Dental Implants Procedure

How are dental implants placed?

Most dental implant surgery procedures are performing in the office of Dr.Roshkovan DDS, MSc. Local anesthesia is usually adequate for these out-patient procedures but various other forms of patient sedation (such as nitrous oxide and oral sedation) may also be used. Adjunctive surgical procedures, such as vertical bone augmentation, sinus lifting may be performed as separate procedures or at the same time as implant placement. Each surgical procedure is different depending on the clinical situation.

Why is the surgical procedure a three-step process?

The most widely practiced method of placing implants in dentistry is a “staged surgery” procedure. The first stage consists of surgically burying the dental implant (which replaces the tooth root) flush with the bone but underneath the gum. This protects the implant from force while it is healing. At the end of this healing period, the implant needs to be surgically exposed by removing some of the overlying gum or soft tissue.

At this second stage, the Dr. Igor Roshkovan checks the implant for its successful integration or osseuintegration and connects some form of post which penetrates through the gum tissue into the mouth. This post is called the abutment. Abutments come in many forms and can be stock-manufactured or custom-molded by Igor Roshkovan DDS, MSc. and his laboratory. The gum is allowed to heal around the abutment and form a cuff or collar through which the Dr.Igor Roshkovan has access to the implant when preparing the final restorative stage of placing the prosthetic tooth or teeth.

Research has shown that it is often possible to place a suitable abutment at the same time as the implant. This has certain limitations but can eliminate the need for a second surgery to expose the implant. However, the implant still requires adequate healing time for the bone to osseointegrate.

The abutments must also be protected from chewing forces during this period to assure effective bony integration and successful healing. Once the implants have had a chance to heal and have been tested for successful integration, the final restorative step takes place. This stage consists of fabricating and connecting the prosthetic teeth to the successfully osseointegrated implants.

What is One-Stage Surgery?

This method employs a non-submerged one-piece implant that has a metal collar designed to protrude through the gum while the bone is healing to the implant. After a suitable healing time, an abutment can be connected to the implant, allowing for fabrication of the crown to replace the missing tooth. Alternatively, a one-stage technique can be achieved by immediate connection of a temporary healing abutment to a two-piece implant that protrudes through the gum in much the same way as a one-piece implant. Both single stage and two-stage implants have similar success rates.

What is the overall success rate for dental implants?

Despite decades of clinical and scientific research, dental implants do not have a 100% success rate. However, the success rates have improved dramatically since the introduction of dental implant surgery and the dental profession can proudly report success rates well above 80% for most implant patients. Similarly, long-term success rates are in the high 85% range and are likewise improving.
