Many of our patients and prospective patients ask us similar questions about dentures and implant dentures when they visit High River Denture & Implant Clinic. Read our answers below.
Implant dentures are replacement, or substitute tooth roots, used to replace natural tooth roots in areas of the mouth where teeth are missing.
The reason it is so important to replace the tooth root as well as the visible part of the tooth is that natural tooth roots are embedded in the bone, stimulating bone growth and providing the stable foundation necessary to bite and chew.
When teeth are missing, the bone that previously supported those teeth melts away, or deteriorates. This process is called bone resorption. However, the bone can be preserved by replacing missing tooth roots with implant dentures. Since the bone actually forms a strong bond to the implants, they can serve the same functions as natural tooth roots.
The overall quality of life is enhanced with replacement teeth that look, feel and function like natural teeth. With implant-supported replacement teeth, the appearance of the smile is more natural and the teeth function more like natural teeth. The result is increased comfort and confidence when smiling, speaking and eating.
Integrity of facial structures is preserved
By preventing the bone resorption that would normally occur with the loss of teeth, the facial structures remain intact. This is particularly important when all of the teeth are missing, as the lower one-third of the face collapses if implants are not placed to preserve the bone.
Adjacent teeth are not compromised to replace missing teeth. Tooth replacement with traditional tooth-supported bridges requires grinding down the teeth adjacent to the missing tooth/teeth, so that the bridge can be cemented onto them. This tooth structure can never be replaced and the long-term health of these teeth is compromised. Partial dentures have clasps that hook onto adjacent teeth, putting pressure on them as the partial rocks back and forth. Eventually these teeth can loosen and come out as a result of this pressure. Replacing missing teeth with implant-supported crowns/bridges does not involve the adjacent natural teeth, so they are not compromised or damaged.
The mouth is restored as closely as possible to its natural state. By replacing the entire tooth, including the root, it is possible to replicate the function of natural teeth, with a strong, stable foundation that allows comfortable biting and chewing. In addition, nothing in the mouth looks or feels artificial.
Increased stability and a sense of security that teeth will not fall out when eating, laughing or sneezing
People who wear dentures often worry that their dentures will fall out when they laugh, sneeze and sometimes even when they eat. Since the bone bonds to the implants, replacement teeth have a stable foundation and are securely attached to the implants, so there is no fear that teeth will fall out.
Improved health due to improved nutrition and proper digestion
People with dentures usually have problems eating certain foods, such as fresh vegetables and fruits, which can compromise their nutrition. Additionally, since it is difficult to chew properly with dentures, digestion is often compromised.
Since implants preserve bone, preventing deterioration of the facial structures, appearance is improved. Collapse of the lower one-third of the face caused by complete tooth loss can be visually corrected and the remaining bone preserved. The appearance of wrinkles around the mouth caused by posterior bite collapse or complete facial structure collapse, are virtually eliminated. The smile is improved when replacement teeth look more like natural teeth. Even when only one tooth is missing, long-term aesthetics are usually much better with an implant-supported replacement tooth than with a traditional tooth-supported bridge. This is particularly important in the front of the mouth, where preventing a visible bone defect is critical for natural appearance.
Improved ability to taste foods
Wearing an upper denture can prevent someone from really tasting food, as the roof of the mouth is covered. With implant-supported replacement teeth, it is not necessary to cover the roof of the mouth, so it is possible to enjoy the taste of foods.
Increased convenience of hygiene
It is much easier to care for an implant-supported crown, which can be cleaned like a natural tooth, as opposed to a tooth-supported bridge, which requires the use of a floss threader for proper cleaning. It is also easier to clean implant-supported replacement teeth than a removable partial.
Elimination of denture adhesives
Since implant-supported teeth are securely attached to the implants, there is no need for messy denture adhesives, which are often needed to keep dentures from falling out.
Restored self-esteem and renewed self-confidence
Many of the people who now enjoy the benefits of implant-supported replacement teeth state that their self-esteem and self-confidence have been restored as a result of improved appearance, function, comfort and health.
Nearly everyone who is missing one or more teeth and in general good health is a candidate for implant denture treatment. There are a few medical conditions that can undermine the success of implant treatment, such as uncontrolled diabetes and smoking. However, there are very few conditions that would keep someone from having implant treatment altogether.
Quality and quantity of available bone for implant placement is more often a factor in qualifying for implant dentures than medical conditions. However, even people who have lost a significant amount of bone can qualify for implant denture treatment with additional procedures to add bone or create new bone. Advances in this type of treatment have made it possible for thousands of patients who would not previously have been considered candidates to have successful implant treatment.
The first step is an examination and consultation with a dentist or dental specialist to determine whether or not you are a candidate for implant treatment. This usually involves x-rays and may include taking impressions for models of your teeth. If you have already lost a significant amount of bone, additional x-rays taken at another facility that specializes in this type of x-ray may also be recommended.
During the examination, your dentist or dental specialist will be evaluating the area(s) of your mouth where teeth are missing, including the amount of bone available to support the placement of implants. Your dentist will also be evaluating the type of replacement teeth that will best meet your needs. A review of your health history will indicate whether there are any medical conditions that could prevent you from being a candidate for implant treatment.
Following the initial consultation, you may be referred to a dental specialist for another evaluation. If you are referred to a surgical specialist, this will typically be for the purpose of further evaluating the quality and quantity of available bone to determine the number of implants necessary, as well as whether additional procedures may be needed to obtain the desired functional and aesthetic result. If you have already lost a significant amount of bone, typically the surgical specialist will be evaluating the possibility of procedures to add (graft) bone, or create new bone.
Implant Placement Procedure
The implants are placed in the bone using a standard surgical technique. Following the implant placement procedure, the implants may be left undisturbed for a period of 3 to 9 months so that the bone can bond with the implants, or the implants may be placed and immediately loaded with replacement teeth. Your surgeon and dentist will select the procedure that is best for you. In any case, you will always have some type of temporary replacement teeth, so that you never have to be without teeth during treatment.
Abutment Attachment Procedure
Following the appropriate healing period, a small connector, or extension, called an abutment, is attached to each implant. The permanent replacement teeth will eventually be attached to the abutments.
Fabrication of Replacement Teeth
A series of appointments with your dentist will be needed to take impressions of your teeth and the implant abutments, to place temporary replacement teeth, to select the appropriate shade for your replacement teeth, and to try them for proper fit. In between these appointments, the laboratory technician will fabricate your replacement teeth and the underlying structures that will be attached to the implants.
Implant dentures preserve bone because they function like tooth roots, firmly embedded in the bone. In order for the implants to become embedded in the bone, the bone must bond to the implants. This process takes anywhere from 3 to 9 months, depending upon the quality of the bone into which the implants are placed.
There are other treatment options that do not include implant dentures and take less time to complete; however, none of these traditional methods of tooth replacement preserve bone. And, in fact, dentures and partials actually accelerate the bone resorption process. In selected cases, implant dentures can be immediately loaded after placement. Thus the time to complete this treatment plan is minimal. Your restorative dentist and/or surgeon will evaluate your options for immediate loading.
Most implant patients report that the discomfort is far less than they expected, and is much like having a tooth extracted. And although everyone is different with regard to pain tolerance, most patients are very comfortable simply taking Motrin afterward.
Documented clinical research demonstrates that implant-supported replacement teeth have been successful for over 35 years. These were some of the first root-form implant cases ever completed and they have been closely monitored from the beginning. It is highly likely that these cases will be successful throughout the lifetime of those patients.
Implant dentures are designed to be permanent; however, many factors contribute to the long-term success of implant treatment, such as home care and regular maintenance visits to the dentist or dental specialist.
By comparison, research demonstrates that the typical tooth-supported bridge lasts from 7 to 10 years and those partials and dentures are functional for approximately 5 years. Insurance statistics indicate that bridges, partials and dentures last 5 years and they generally pay for replacements every 5 years.
Implant denture treatment is one of the most successful procedures in the medical/dental field, with documented success rates over 95%. Although successful treatment is very predictable, there are rare occasions where the bone does not completely bond to the implants. When this occurs, new implants are placed. Smoking or putting too much pressure on newly placed implants, as with excessive grinding of the teeth, can cause problems with the bone bonding to the implants, and should be avoided.
The home care recommended varies depending upon the type of implant-supported replacement teeth. For example, a single implant-supported crown is cleaned like a natural tooth, with regular brushing and flossing. Implant-supported bridges that replace a few teeth are cleaned like tooth-supported bridges, brushing and flossing with a floss threader.
Home care is a little more complicated for people who are missing all of their teeth. Special brushes and floss are often recommended. With overdentures, it is necessary to clean the implant attachments, as well as the overdenture. Permanently fixed implant supported replacement teeth are cleaned like all other bridges.
In all cases, it is recommended that patients see their regular dentist and hygienist at least twice each year unless they routinely see the periodontist, in which case they would continue to alternate visits. If a surgical specialist placed the implants, it is usually recommended that the patient see the specialist at least once each year as well. These visits, combined with proper home care, are essential to the long-term success of implant treatment.
An investment in implant denture treatment is an investment in overall health, appearance and well-being, as it involves preserving the integrity of facial structures, as well as replacing missing teeth.
The actual cost of implant treatment is based on a number of factors, such as the number of missing teeth being replaced, the type of implant-supported teeth (treatment option) recommended and whether additional procedures are necessary to achieve the proper aesthetic and functional result.
There is often a misconception that there is a set cost for each implant. The fees are calculated based on the amount of time the dentist or dental specialist anticipates spending to complete treatment (implant placement, other surgical procedures, fabrication of replacement teeth) as well as the estimated cost of implants, other components and materials necessary to complete treatment and dental laboratory fees.
The only way to accurately estimate the cost for an individual patient is to have an examination and consultation with a dentist or dental specialist. If a dentist and dental specialist work together on a patient’s treatment, there is a separate fee for each of the doctors.
Insurance coverage of implant treatment depends on the individual policy. However, it is rare to receive any substantial coverage. The benefit coverage is determined strictly by the amount the employer wants to spend on the policy, and how much the insurance companies want to preserve their profit margins. In addition, there are major limitations on most dental insurance plans. In reality, the plans are only designed to cover routine maintenance, emergencies and basic care.
The insurance companies use statistical data to determine the most common procedures submitted on claims, and then set their own “usual and customary fee” schedule for these procedures. They then determine the specific restrictions and limitations for each plan. Because the plans are only intended to cover the basics, there is an annual maximum allowable benefit of $1,000 to $1,500 on most plans.
Although most companies exclude implant dentures as a covered benefit, many of them will pay the same benefit they would cover for the lowest cost alternative treatment option (partials and dentures) and some of the diagnostic records, if a specific request is made for “alternative benefits.” Even if an individual policy includes implants as a covered benefit, the amount of coverage is still limited to the annual maximum allowable.
