Abstract:
The removal force of abutments with various implant abutment connections is of interest. Hence, thirty implants were categorized into types, i.e., external hex, internal hex and conical connections. The highest removal force was recorded in conical (192.7 +/- 10.9 N) and internal hex (174.3 +/- 15.4 N) and the lowest were in the external hex (145.8 +/- 12.6 N). Important disparities between groups were identified (p < 0.05). Thus, the conical connections provide better mechanical anchoring, thus improving the stability of the implants.
