First molar replacement with an osseointegrated implant.

The effective use of two osseointegrated Brånemark implants for the replacement of a single first molar is described. A first molar lost to endodontic failure was replaced using two 10-mm titanium fixtures in the area previously occupied by the mesial and distal roots of the molar. The use of multiple fixtures in the molar area provided a better distribution of forces to the alveolar bone. At 1-year recall, the patient exhibited excellent oral hygiene and normal function. Adequate bone dimensions are a prerequisite to this treatment.
