Q. The height of the alveolar ridge has been restored. This is important for both esthetic and functional reasons. From an esthetic standpoint, the size and contour of the prosthesis is affected by ridge height. From a periodontal standpoint, it is important to establish gingival attachment levels on the implants that coincide with the periodontal attachments on the adjacent teeth.

Q.

R. Adequate expansion of the osseous crest allows placement of osseointegrated implants in a more coronal position than would be normally possible. The objective is to place the fixture head so that the anticipated gingival attachment to the implant will be at a similar level as the periodontal attachment to the adjacent teeth. The distraction objective is to expand the alveolar housing to provide a site for implants or to create additional tissue for a second stage reconstructive procedure.

PRINCIPLE: An osseointegrated fixture adjacent a tooth functions best when their respective gingival attachment mechanisms are at the same vertical height.

R.

S. The osseointegrated fixtures are positioned relatively coronal in the alveolus. To remain stable, the anticipated gingival attachment on the implant fixture should minimally impact the periodontal attachment on the adjacent teeth. Proper positioning of the implant is important in achieving this goal. Adequate site reconstruction is often a prerequisite to satisfactory implant positioning. The biologic width on the implant will probably be similar to that of the tooth.
