E. Intended Use of the Device

Nobel Biocare's TiAdapt™ Abutment System is a set of screw retained preparable abutments that are secured to an endosseous implant and are intended to function as an anchor to which prosthetic devices, such as artificial teeth, may be attached using dental cement to restore a patient's chewing function.

F. Comparison of Technological Characteristics

The technological characteristics between the components of the TiAdapt Abutment System and the corresponding predicate products found in the Brånemark System® are identical.

### Summary Of Safety And Effectiveness Concerns

Safety and effectiveness problems that have been encountered with similar Abutment Systems used with endosseous implants that are currently being marketed include:

- 1. occasional fractures of the screw attaching the abutment to the fixtures usually due to functional overload from masticastory forces:
- 2. screws working loose (usually because torque force below recommended values was applied when the abutment was attached to the fixture) may lead to the formation of granulation tissue at the level of the fixture and abutment connection which may, in turn, result in infection:
- 3. improper initial seating of abutments resulting in gingival inflammation and fistulae formation, both conditions resolve when proper seating of the abutment is accomplished.
- 4. occasional fracture of the abutment screw which is usually caused by poorly designed and/or fabricated restorations that creates overloads or cause's metal fatigue.
