Dental implants are changing the way people live. They are designed to provide a foundation for replacement teeth that look, feel, and function like natural teeth. The person who has lost teeth regains the ability to eat virtually anything, knowing that teeth appear natural and that facial contours will be preserved. Patients with dental implants can smile with confidence.

What Are Dental Implants?

The implants themselves are titanium posts that are surgically placed into the jawbone where teeth are missing. These metal anchors act as tooth root substitutes. The bone bonds with the titanium, creating a strong foundation for artificial teeth. Small posts that protrude through the gums are then attached to the implant. These posts provide stable anchors for artificial replacement teeth.

Implants also help preserve facial structure, preventing bone deterioration that occurs when teeth are missing.

The Surgical Procedure

For most patients, the placement of dental implants involves only one surgical procedure. First, implants are placed within your jawbone. For the first three to four months following surgery, there is a healing collar that protrudes through the gums and acts as an optorator to allow the neck of the implant to be easily accessed.  In some cases, we delay the placement of the healing collar until after the implant has integrated with the jawbone.  A second procedure will be necessary to uncover the implants and attach the healing collar.  Drs. DiGregorio and Anjomshoaa will inform you on when you can return to your general dentist to have posts and crowns made.  You should be able to wear temporary dentures and eat a soft diet during this time. At the same time, your dentist is forming new replacement teeth.  The entire procedure usually takes six to eight months. Most patients experience minimal disruption in their daily life.

Surgical Advances

Using the most recent advances in dental implant technology, Drs. DiGregorio and Anjomshoaa are able to place immediate load implants. These implants do not require a second procedure to uncover them.  In some instances, the implant can be immediately loaded with temporary posts and crowns.  There are even situations where the implants can be placed at the same time as a tooth extraction – further minimizing the number of surgical procedures. Advances in dental implant technology have made it possible, in select cases, to extract teeth and place implants with crowns at one visit. This procedure is called “immediate loading”.

Implants are a team effort between an oral and maxillofacial surgeon and a restorative dentist. While Dr. DiGregorio or Dr. Anjomshoaa performs the actual implant surgery, initial tooth extractions, and bone grafting if necessary, the restorative dentist (your dentist) fits and makes the permanent prosthesis. Your dentist will also make any temporary prosthesis needed during the implant process.

What Types Of Prostheses Are Available?

A single prosthesis (crown) is used to replace one missing tooth – each prosthetic tooth attaches to its own implant. A partial prosthesis (fixed bridge) can replace two or more teeth and may require only two or three implants. A complete dental prosthesis (fixed bridge) replaces all the teeth in your upper or lower jaw. The number of implants varies depending upon which type of complete prosthesis (removable or fixed) is recommended. A removable prosthesis (over denture) attaches to a bar or ball in socket attachments, whereas a fixed prosthesis is permanent and removable only by the dentist.

Drs. DiGregorio and Anjomshoaa perform in-office implant surgery in a hospital-style operating suite, thus optimizing the level of sterility. Inpatient hospital implant surgery is for patients who have special medical or anesthetic needs or for those who need extensive bone grafting from the jaw, hip or tibia.

Why Dental Implants?

Once you learn about dental implants, you finally realize there is a way to improve your  life. When you lose several teeth – whether it’s a new situation or something you have lived with for years – chances are you have never become fully accustomed to losing such a vital part of yourself.

Dental implants can be your doorway to renewed self-confidence and peace of mind.  Our office offers two types of dental implants, Zimmer and Nobel Biocare.  Dr. Drs. DiGregorio and Anjomshoaa have been using these two implant companies since 1982 with continued success. 

A Swedish scientist and orthopedic surgeon, Dr. Per-Ingvar Branemark, developed this concept for oral rehabilitation more than 35 years ago.  With his pioneering research, Dr. Branemark opened the door to a lifetime of renewed comfort and self-confidence for millions of individuals facing the frustration and embarrassment of tooth loss.

Why Select Dental Implants Over More Traditional Types Of Restorations?

There are several reasons: Why sacrifice the structure of surrounding good teeth to bridge a space?  In addition, removing a denture or a “partial” at night may be inconvenient, not to mention that dentures that slip can be uncomfortable and embarrassing.

How do we Determine Implant Stability and Restorability?

I currently determine the stability and restorability of an implant by testing the implant with the OSSTELL ISQ (implant stability quotient). In addition to x-ray and physical exam the implant stability is tested via a Radio Frequency Analysis. This entails directing a magnetic pulse at the implant and measuring the result. It is analogous to striking a tuning fork and measuring the pitch. The reading obtained is reproducible and is a consistent indicator of stability. This will assist me in the long term assessment of the implants.

Are You A Candidate For Implants?

If you are considering implants, your mouth must be examined thoroughly and your medical and dental history reviewed. If your mouth is not ideal for implants, ways of improving outcome, such as bone grafting, may be recommended.

What Type Of Anesthesia Is Used?

The majority of dental implants and bone grafts can be performed in the office under local anesthesia, with or without IV sedation anesthesia.

Do Implants Need Special Care?

Once the implants are in place, they will serve you well for many years if you take care of them and keep your mouth healthy. This means taking the time for good oral hygiene (brushing and flossing) and keeping regular appointments with your dental specialists.
