Completed · Not applicable

Conditions studied: Gingival Tissue

In brief

The primary objective of this study is to compare the amount of implant marginal bone loss radiographically and probing depth in between thin and thick mucosa group that will receive a machined collar implant. Null hypothesis is mucosa thickness does not affect implant marginal bone loss on implant with smooth collar.
