Risk Factors in Dental Implant Surgery

This article is the second in a series for Oral Health. The first article was published in the August 2015 issue, with the title “Surgical Risk Factors in Implant Dentistry: Influence on Failures and Bone Loss”. Table 1 in this article, organizes risk factors in implant dentistry into four categories. These were introduced in the August 2015 article together with the concept of “Evidence Based Dentistry” and a representative case presentation.

Patient Related Systemic Risk factors: (Table 1)
This category of risk factors includes but is not limited to patient related: a) complaints, expectations, psychological suitability and limitations (e.g. clinical limitations and financial limitations), b) history of periodontitis (especially aggressive periodontitis) and c) smoking, systemic disease and medications.

• b) History of Periodontitis:
A patient’s history of periodontitis and in particular aggressive periodontitis needs to be determined from the information gathered from both the initial patient interview, previous dental records as well as from the diagnostic information gathering phase. There have been several articles studying this issue. Readers are referred to a meta-analysis published in 2014.1 A conclusion can be drawn from this review that a history of aggressive periodontitis poses a negative risk factor for and should be taken into account and included as part of the “informed consent” process and treatment.

• c) Smoking, Systemic Disease and Medications:
The patient’s dental, medical and habit history and in particular current conditions that could impact upon the outcome, need to be questioned and evaluated at the initial patient interview and where indicated investigated in more detail. Outside consultations may be needed to determine if any pre-treatment precautions need to be taken or if treatment is absolutely contra-indicated.

Patient Informed Consent
Successfully achieving “patient informed consent” is a critically important aspect of overall patient care. It is a legal and ethical duty for dentists to make sure that the patient understands the important aspects of treatment. There have been several recent RCDSO Dispatch articles that have addressed this issue, for example “Dental Implant lawsuits”, August/September 2015 issue, “Informed Consent Learning program”, November/December 2015 issue and “Informed Consent From
Material Risks to Material Information”, February/March 2016 issue.

New study finds troubling rates of dental implant complications

The study evaluated rates of dental implant loss and peri-implantitis as the result of dental implants.

Any dental procedure comes with the chance of infection, but a recent study out of Sweden has discovered that patients with dental implants run a high risk – and that several contributing factors can exacerbate this risk

The research out of the University of Gothenburg aimed to evaluate the correlation between dental implants, implant loss and peri-implantitis, a destructive infection that affects the tissue surrounding dental implants and can result in loss of supporting jawbone. Researchers also explored the relationship between periodontitis and rates of implant loss.

The study consisted of 4,716 randomly selected participants that had all had dental implants in 2003-2004. Researchers sent out a survey and received dental records and charts for 2,765 patients in the study. 596 patients were also examined at a nine-year follow-up appointment. The results found that almost eight percent of patients with dental implants experienced the loss of at least one implant within that timeframe.

More research on dental implants: New discovery can prevent dental implant infections

“Altogether, 7.6 percent of patients had lost at least one implant and 14.5 percent had developed peri-implantitis with pronounced bone loss,” reported Dr. Jan Derks, a researcher at Sahlgrenska Academy. 50 percent of patients presented with some signs of peri-implantitis, but only 14.5% were considered to have moderate to severe implications (equating to a crestal bone loss exceeding 2 mm). The 7.6 percent that had lost an implant showed an average loss of 29 percent of bone support.

Dr. Derks’ research also found that patients with preexisting periodontitis experienced an increased risk of peri-implantitis. Smoking was also identified as a risk factor contributing to early implant loss. The study also reported that “progression of peri-implantitis occurred in a non-linear, accelerating pattern, and, in the majority of cases, the onset of the disease had occurred early.”

Interestingly, the rate of implant failure did not differ between the general practice and specialty practices. “22% of all patients in the present sample received their implants in a general practice setting, and implant los in this subgroup was not different from outcomes in patients treated in specialist clinics,” the study stated.

“Peri-implantitis appears to develop within a few years and then progresses quickly at an accelerating pace,” said Dr. Derks. He hopes that the information gained from the study can help dentists minimize the risk of peri-implantitis and implant loss.

Dental implants Instructions

Dental implants have been accepted as a viable treatment option for completely and partially edentulous patients.1,2,3 Further improvements toward the successful osseointegration of dental implants have involved modifications to both surface topography and surface chemistry.4 Implant design (i.e., types and dimensions), surgical procedure, implant placement time, and time prior to loading have been shown to influence implant survival rates.5,6,7,8.

Why to choose this treatment dental?

Therefore, risk factors associated with implant failure have become a frequently discussed topic in recent dental research. Among patient factors, male gender, smoking, autoimmune disease, and penicillin allergy have been found to trend toward higher failure rates.9,10 In contrast, short implants in mandibular posterior sites have been found to have a survival rate of 100%, while the same was not true for implants in the maxillary posterior position, wherein 6-mm implants had a survival rate of only 87%.

Most survival study designs are longitudinal and retrospective with many years of follow-up. Their statistical methods use implant failure as the unit of analysis, without considering multiple implant failures in the same patient. Outcomes related to implants in a single patient must be more closely correlated than those in separate patients; ignoring these correlations could result in a bias in p-value computations.11,12,13

Therefore, in this retrospective study, we aimed to evaluate dental implant outcomes and to identify risk factors associated with implant failure over 12 years via dental records of patients attending an educational institution.

Dental Implants – Will They Do the Work?

The niche of dentistry along with the technology that is put to use by the dentists is developing at an alarming pace. There was a time when the commoners had to opt for removable dentures, if they lost their teeth. Times are changing and now we have access to dental implants. What is dental implant motor? What are the various kinds of dental implants? Can I opt for this procedure if I lose a couple of teeth? The queries posed to cosmetic dentists in the real world as well as in the virtual world (internet discussion forums) are also increasing. If you are in need of a dental-implant, the first thing you must be doing is to fix an appointment with the local dentist. Sometimes, expert cosmetic dentists can rectify minor problems with the use of ulterior technology.

A dentist will examine the patient thoroughly. He will also employ advanced technologies that will generate portable dental x rays machine images of the jawbone and the gums. All these are required to determine the type of dental implant, which will work out to be highly feasible for the patient. Yes, the ‘one size fits all’ paradigm does not work out over here. Many patients would shun away from dental-implant procedures because of the pains. However, you must realize that you are in safe hands. An expert dentist will employ the least painful procedures. I am not stating that the procedure is painless. In the words of expert dentists, dental implants might cause ‘minor discomforts’. Once the process is completed, the dentist might ask the patient to seek respite on painkiller prescriptions. Do not worry, the dentist will provide the same. The healing period varies greatly – if you follow the guidelines cited by the dentist, it will take a maximum of three to four weeks for the pain to subside. I understand that many readers might have various notions when it comes to the success rates of dental implants.

You must shed the belief that this is a new technology. Dental-implantation procedures have been in existence since some years. Throughout these years, dentists have perfected the niche. Hence, the success rate of dental implant procedure is 90 to 95 percent. Does that make you feel better? I do realize that you might have numerous queries surfacing in your mind right now. The best person, who can give you satisfactory answers, is none other than your dentist. It is important to find the right kind of dentist who is well versed with dental implants. Someone who utilizes the latest techniques will be your best bet. The internet is a good place to initiate the search for the finest cosmetic dentists. You must also consider the number of sittings (appointments) with the dentist.

About Its Material and Methods

Patient population

Sixty-one implants were inserted in 7 adult patients (4 female and 3 male; age range 38 to 62 years). All patients were free of any medical conditions interfering with implant treatment. Five (71.43%) patients were smokers and 2 (28.58%) were nonsmokers. All patients had been referred from general dentists and were not previously treated for periodontal disease at the time of the first examination.

Examination

Each patient underwent a comprehensive dental and periodontal examination. Periodontal charting included documentation of probing depths, recessions, clinical attachment levels, bleeding on probing, tooth mobility, furcation involvement, and plaque scores. Periodontitis was diagnosed in the presence of more than 4 sites with clinical attachment loss exceeding 4 mm, radiographic evidence of alveolar bone loss, and bleeding on probing. Impressions for diagnostic casts were taken and a panoramic radiograph was obtained. Casts were mounted on a semi-adjustable articulator after face-bow transfer and check-bite registration.

An occlusal analysis was performed, diagnostic wax-ups were prepared on the articulated casts, and restorative treatment needs determined. Once the restorative and periodontal treatment plans were established, radiographic and surgical guides were fabricated to facilitate implant placement. Table 1 shows the patient treatment plan and time schedule.

Periodontal treatment

Periodontal treatment, including surgical treatment if necessary, had been performed previously on all patients.

Implant selection

Unless outlined differently, cylindrical screw implants with a large-grit sandblasted and acid-etched surface and either a 1.8-mm or a 2.8-mm smooth neck were used (ITI Straumann Standard Plus with a 1.8-mm smooth neck; (ITI Straumann Standard with 2.8-mm smooth neck)Implant size was determined based on assessment with a panoramic radiograph taken with a radiographic stent in place, and a clinical examination.

 

Some Information about Dental Implant Surface

Dental root form implants are manufactured from a highgrade titanium alloy, the surface of which consists of a micro layer of titanium oxide. The implant surface can also be treated by plasma spraying, acid etching, sandblasting or coated with HA. The removal of plaque and calculus deposits from these implant surfaces with Dental Instruments designed originally for cleaning natural tooth surfaces can result in major alterations to the delicate titanium oxide layer. Altering the surface topography by roughening the surface may enhance calculus and bacterial plaque accumulation.

Resulting scratches, cuts or gouges may also reduce the corrosion resistancy of titanium, and corrosion and mechanical debris can accumulate in the surrounding tissue. The aim of procedures for debriding dental implants should be to remove microbial and other soft deposits, without altering the implant surface, and thereby adversely affect biocompatibility. Increased surface roughness can lead to an increase in bacterial accumulation and resultant soft tissue inflammation. Because of the critical nature of the implant/soft tissue relationship, metal ultrasonic scaler tips, hand scalers or curettes should not be used as they have been shown to significantly alter the titanium surface.

Current methods for professional cleaning of implant or titanium transmucosal elements include the set of plastic ultrasonic tips( ultrasonic scaler ) or hand instruments followed by the prophy cup polishing method or various types of floss and buffing strips. The design of the permanently cemented super structure often does not allow adequate access for the prophy cup, especially in interproximal areas, and plastic instruments are not very efficient for the removal of plaque or mineralized deposits. In addition, the prophy cup and paste method may leave residual paste at the implant/soft tissue interface area.

Airpolishing consists of directing, water, air and sodium bicarbonate towards the tooth or implant surface, resulting in efficient removal of bacterial plaque and soft mineralized deposits. The residual powder is biocompatible and being soluble is not retained at the implant/soft tissue interface( dental implant machine ).

Two airpolishing systems are currently available. One system, typically available on the Dentsply Prophyjet? and Cavijet,? the EMS Airflow, and the Satelec units, delivers the air and powder, typically at 60-80 psi pressure through one nozzel and the water through a separate concentric nozzel. Some mixing of the streams takes place at the interface of the streams, but the centre of the stream consists essentially of dry powder. This “Biphasic” stream is directed at the tooth or implant surface. Several studies have investigated this system, and its effects on implant surfaces, and conclude that this system can result in significant changes to the implant surface.

The Modern Technology of Dental Implant

The primary use of dental implants is to support dental prosthetics. Modern dental implants make use of osseointegration, the biologic process where bone fuses tightly to the surface of specific materials such as titanium and some ceramics. The integration of implant and bone can support physical loads for decades without failure.

For individual tooth replacement, an implant abutment is first secured to the implant with an abutment screw. A crown (the dental prosthesis) is then connected to the abutment with dental cement, a small screw, or fused with the abutment as one piece during fabrication. Dental implants, in the same way, can also be used to retain a multiple tooth dental prosthesis either in the form of a fixed bridge or removable dentures.

Dental Laboratories and dental technicians( dental laboratory equipment ) often work behind the scene with the dentist and/or the specialist and are an integral part of the treatment process for patients. A thorough understanding of patients’ anatomical limitations during treatment planning is essential, as is recommending and implementing the appropriate impression/transfer techniques, abutment design, and restoration design.

The modern dental laboratory, armed with a dental technician with the appropriate knowledge, skill, and experience can provide implant restorations in a financially, technically and esthetically predictable manner, delivering the highest standard of patient care.

In order to improve the predictability of any treatment outcome, it is critical to understand whether the patient’s anatomy, bone, and soft tissue, is favorable for esthetic integration. Dr. John Kois has noted that the patients’ presenting situation is the most important factor in determining whether an optimum esthetic result can be achieved.

As every situation is different, it is important for the patient to realize that compromises to the way the teeth look may still occur. Considerations that may compromise the symmetry of an attractive smile may include medical and/or dental history, gum, bone or existing teeth.

An implant supported bridge (or fixed denture) is a group of teeth secured to dental implants so the prosthetic cannot be removed by the user. Bridges typically connect to more than one implant and may also connect to teeth as anchor points. Typically the number of teeth will outnumber the anchor points with the teeth that are directly over the implants referred to as abutments and those between abutments referred to as pontics. Implant supported bridges attach to implant abutments in the same way as a single tooth implant replacement by dental implant machine. A fixed bridge may replace as few as two teeth (also known as a fixed partial denture) and may extend to replace an entire arch of teeth (also known as a fixed full denture). In both cases, the prosthesis is said to be fixed because it cannot be removed by the denture wearer.

 

What Should You Do to Your Teeth After Dental Implants

The advent of the dental implants marked a novel way in the insertion of dentures. Significant portions of the people were complaining of discomfort after dentures were inserted. Dentures also had to be removed while sleeping or at times during the day. The dentures also demanded a significant amount of cleaning and safeguarding. Dental implants cleared the path for all these problems. Further, implants can be made to compliment any of the other dental appliances such as bridges or crowns. They can used to provide strength to the dental devices including the dentures.

Dental implants are artificial teeth that are surgically implanted in the mouth in place of missing teeth, teeth that need to be removed due to decay or irreparable disfigurement. The root of a dental implant is placed in the jaw bone, giving them the appearance and feel of authentic teeth.

Dental implants are impervious to tooth decay, you’re still prone to gum disease. That’s why you need to brush, floss and visit your dentist regularly. There are some additional steps that you should take keep your new teeth just as dazzling as your original pearly whites.

See your dental specialist twice a year. Not only will she thoroughly clean your implants and remove plaque, but a cosmetic dentist in New Jersey can evaluate if your implants need adjustments.

Your dentist may also prescribe chlorhexidine gluconate mouthwash, a germicidal rinse that reduces bacteria and treats gingivitis. This powerful mouthwash also helps reduce the risk of post-op infections.

Because your new “fake teeth” actually perform like the real thing, you still need to practice the same oral habits. That means brushing twice a day, flossing daily, and regular dental checkups. Here are some oral hygiene recommendations from the American Dental Association:

Use a toothbrush with soft bristles that can reach all your teeth.
Buy a new toothbrush every three or four months or earlier when bristles fray.
Don’t forget to brush your tongue as well. The tongue harbors bacteria that can lead to tooth decay and gum disease.
Floss daily to remove food particles and bacteria from between teeth and under the gum line.

Making Your Smile more Beautiful by Dental Implant

Your smile approved dentist places the implant into the jaw then inserts a screw to prevent debris from entering. It will take 3 to 6 months for the implant to fuse with the jawbone, during which time the gum is secured over the implant.

Upon returning to the dentist, the implant is uncovered and an extension called a post is attached. Once the gum tissue has healed around the post, the implant and post act as the foundation for the new tooth. Finally, the dentist makes a crown that best suits your natural teeth, considering factors including size, shape and colour. Once completed, the crown is attached to the implant post and you can enjoy your beautiful new smile!

The recovery time for dental implants is dependent on the patient, and it differs from one individual to another. Depending on your circumstances, the downtime could be a couple of days or a couple of weeks. On average, it takes just a couple of days to feel back to normal. The complete healing of your jawbone and gum tissue takes approximately 3-6 months.

Once healed, dental implants should be painless and comfortable. Immediately after surgery, however, discomfort and mild pain is expected to last up to a week. Your dentist may prescribe you something for the pain and to avoid infection; otherwise, over-the-counter painkillers can help to manage the pain.

Different dental implants may require different care. Your dentist will ensure you are equipped with the correct products, such as special brushes, to care for your implants. Maintaining good oral hygiene is vital for preventing infection around your dental implant.

With thorough cleaning and frequent visits to your dentist for professional cleaning and maintenance, your dental implants will be well looked after, allowing you to enjoy them for many years to come.

The Procedures of Dental Implant Treatment

The use of dental implants has become more and more popular over the years.  A dental implants treatment is for individuals who have a missing tooth or teeth.  They are also for those who need support for a bridge or a denture.  The most common reason though is to replace a missing tooth or teeth, permanently.

It is important that you know just what an implant is so you know what to expect as a result of the dental implant procedure. A dental implant is a device that has been particularly fabricated and manufactured to act like and look like your own teeth. The implant will take the place of a missing or damaged tooth in your mouth. The tooth is often made of a combination of titanium and other materials and is designed to look and feel just like a normal tooth would.

The procedures needed to put in a dental implant model can take some time. It is a surgical procedure that you can have performed. The procedure involves placing an implant into your upper or lower jaw, wherever the implant is required. A screw is then positioned into the implant area and the gum tissue replaced over the implant to help secure it into place.

This first step is then allowed to heal properly before the next step occurs, where a post gets placed so that the artificial tooth (which is the dental crown), can be affixed securely to it in the implant, giving you the tooth you want.

The implant will act just like your normal teeth would and no one will be able to tell the difference by looking at you. The implants, unlike your other teeth, will not wear over time and can be brushed and treated just as you would any other tooth that you have. As long as the other teeth around the implant are healthy ones, you will not have any problems at all.

Having dental implants is nowhere near as messy or hard to take care of like your traditional dentures. You can brush your dental implants just like you would regular teeth. No more fighting with messy, sticky, and sloppy adhesives. Also, dental implants look more realistic than traditional dentures and have a very comfortable feel to them.
