ARMAMENTARIUM

OSSEOCONDUCTIVE IMPLANT SURFACES

The TiUnite surface on Nobel Biocare implants has been shown to support the healing process and to maintain initial implant stability better than machined titanium implants. TiUnite is a highly osseoconductive surface.

Position and Angulation of the Implants

The tooth positions for the planned restoration should be decided preoperatively. The ideal length and angulation of implants are best achieved by using the NobelGuide (see Chapter 4). This allows selection of the most appropriate position and angulation for each implant. The existing removable prosthesis often serves as a guide for these positions. In some cases, a diagnostic wax-up is necessary. The prosthetic team must ensure that the surgical team clearly understands the tooth positions required for the final prosthesis. A good means of doing this is to provide a surgical guide. A surgical guide can be fabricated quickly and simply by making a clear acrylic resin replica of the existing removable denture or the waxed-up try-in (see Chapter 4). Except for a supporting posterior connection, the palatal area of the replica is cut away, leaving only the buccal contours of the teeth.

The process for implanting the Brånemark Zygoma implant follows these steps.
