Bone-to-Implant Contact: Its Relationship to Factors That Affect Primary and Biologic Implant Stability.

Abstract

The authors assessed the literature regarding bone-to-implant contact (BIC). A wide range of mean BIC percentages was observed with respect to different commercially inserted implants. Higher BIC related to mandibular implants was found compared to maxillary fixtures and with respect to anterior versus posterior implants. Higher bone density is associated with better implant stability and BIC, while rough implant surfaces provide increased BIC versus smooth surfaces. This article discusses how to determine the percentage of BIC and describes factors that affect its values.
