Question 1 of 1
1. Question
How much bone is recommended at a mini¬mum on the facial and palatal surfaces of the implant to support the ideal orofacial implant position?
Correct
The correct answer is C. The recommended orofacial implant position is contingent upon a minimum of 1.0-mm thickness of facial and palatal bone. 1.0 mm of facial or palatal bone is recommended to ensure stability of the hard and soft tissues. If the facial or palatal bone wall width is less than 1-mm thick, augmenta¬tion procedures are indicated. Ideally, the axis of the implant should be angulated so that the screw channel of a screw retained restoration is located behind (palatal) to the incisal edge of an implant placed in the anterior region.
0. 5 mm is too thin amount of bone to ade-quately support the implant. To ensure pre-dictability of hard and soft tissue stability, a minimum of 1.0-mm thickness of bone is rec-ommended on the facial and palatal aspects of the implant. 0.25 mm is definitely too thin amount of bone to adequately support the im-plant fixture. Such a thickness is likely to result in fenestration.
2.0 mm is greater than the 1.0 mm mini¬mum thickness required facial and palatal to the implant fixture. While 2.0 mm would ad-equately support the implant fixture, the ques-tion asks for the minimum thickness of bone. Therefore, the correct answer is 1.0 mm.Incorrect
