Simply, Dental Implants are small titanium cylinders that are inserted into the jaw to replace the roots of missing teeth. After a period of healing, a porcelain or gold crown is cemented over the implant. Dental Implants allow patients to smile, chew and function normally. Although you have a number of restorative options for the treatment of missing teeth, none have proven to be as effective and durable as implants. In many cases, Dental Implants may be the only sound choice for the replacement of missing teeth and supporting structures. People who have lost teeth often feel too self-conscious to smile, talk, and chew naturally. This can lead to secondary health problems like malnutrition and a low self-esteem. Regardless of the nature of problems related to tooth loss, Dental Implants provide a simple solution and the results are proven.
Advantages of Implant Dentistry
Dental Implants are stronger and more durable than their restorative counterparts (bridges and dentures). Implants offer a permanent solution to tooth loss. Additionally, implants may be used in conjunction with other restorative procedures for maximum effectiveness. For example, a single implant can serve to support a crown replacing a single missing tooth. Implants can also be used to support a dental bridge for the replacement of multiple missing teeth, and can be used with dentures to increase stability and reduce gum tissue irritation. Procedural advancements, including the development of narrower “mini” implants, mean that more people than ever before are candidates for Dental Implants.
The Dental Implant Procedure
Today’s Dental Implants are virtually indistinguishable from other teeth. This appearance is aided in part by the structural and functional connection between the dental implant and the living bone. Implants are typically placed in a single sitting but require a period of integration with the bone before they can be restored. Integration of an implant with the bone can take anywhere from three to six months. Once this happens, the dentist can complete the procedure with the placement of a crown or anchoring of a denture.
Detailed procedural steps for Dental Implants are as follows:
Preparing the Jaw for Implantation: A Dental Implant is commonly composed of a titanium screw and a crown. A small-diameter hole is drilled at where the implant is going to be placed in order to guide the titanium screw that holds a Dental Implant in place. To avoid damaging vital jaw and face structures a surgeon must use great skill and expertise when boring the pilot hole and sizing the jaw bone. The surgeon will consult various x-rays that pinpoint these structures.
Placement of the Implant: After the initial pilot hole has been drilled into the appropriate jaw site, it is slowly widened to allow for placement of the implant screw. Following this placement, a protective cover screw is placed on top to allow the implant site to heal and the dental implant to anchor (osseointegration). After several months, the protective cover is removed and a temporary crown is placed on top of the dental implant. The temporary crown serves as a template around which the gum grows and shapes itself in a natural way. The process is completed when the temporary crown is replaced with a permanent crown.
Success Rates of Dental Implants
Dental implants are among the most successful procedures in dentistry. There is no guarantee that an implant procedure will be successful, but studies have shown a five-year success rate of 95% for lower jaw implants and 90% for upper jaw implants. The success rate for upper jaw implants is slightly lower because the upper jaw is less dense than the lower jaw, making successful implantation and osseointegration potentially more difficult to achieve.
Dental implants may fail for a number of reasons. The cause is often related to a failure in the osseointegration process. For example, if the implant is placed in a poor position, osseointegration may not take place. Dental implants may break or become infected (like natural teeth) and crowns may become loose.
If you are a smoker who is considering a dental implant, your dentist will likely advise you to give up smoking before undergoing the process because smokers face a higher risk of implant failure. Since the procedure can be extremely expensive, you may risk wasting your money on dental implants if you do not give up the habit. On the plus side, dental implants are not susceptible to the formation of cavities.
Implant Dentistry: New Procedural Strategies
Dentists trained to perform implants, crowns and/or surgery have begun to use a new strategy for the replacement of missing teeth. Dental implants are placed into locations where teeth have recently been extracted. When successful, this new strategy can shed months off of the treatment time associated with dental implants because osseointegration is sped up. Candidacy for this type of early intervention is dependant upon anatomical factors of the extracted tooth site. For example, in many cases the extracted tooth site is wider than the implant, making it impossible to place the implant into the site immediately after extraction. Dental work would have to be performed first in order to create a perfect fit for the implant.
Another strategy for implant placement within narrow spaces is the incorporation of the mini-implant. Mini-implants may be used for small teeth and incisors as well as to secure loosely fitting dentures.
