Transitional Implants Prove Effective in Protecting Implant Surgical Sites

Recently, mini transitional implants have been used to support fixed and removable provisional restorations. They have proven to be effective in protecting implant surgical sites, as well as providing the other prerequisites of an acceptable temporary restoration.

These narrow diameter implants are similar to root form implants, providing immediate tooth replacement, and allowing the patient to immediately experience the positive benefits of implant dentistry.

Some important considerations when using transitional implants are as follows: One must maintain adequate space between "temporary" and "permanent" implants. Similarly, adequate space maintenance between transitional implants and natural teeth is essential. Furthermore, to prevent failure from occlusal overload, it is advisable to use an adequate number of mini implants to support the interim prosthesis.

Transitional implants appear to be more successful in the mandible than the maxilla. It has been suggested that this maty be due to enhanced bone density in the mandible. The noticeable deficiency may be overcome by increasing the number of mini implants in the maxilla. Following confirmation of osseointegration of the permanent implants, the transitional implants can be easily removed.

If immediate loading of the implant is desired, three methods of provisionalization are commonly selected:

• A restoration may be delivered the day of implantation, or at the time of uncovering, by indexing the implant platform with a fixture level impression.
• A temporary cylinder or abutment can be used upon which to fabricate a provisional restoration.
• A laboratory processed acrylic tooth shell can be relined and adapted to a temporary or custom abutment.
