Influence of Prosthetic Emergence Profiles and Emergence Angles on Marginal Bone Loss Around Implants with and
Abstract:
The study was aimed to retrospectively evaluate differences in marginal bone loss (MBL) between bone level (BL) implants, with (LMS) and without (noLMS) laser-microtextured collar surface, restored with screwed single crowns with different emergence profiles (EP) and emergence angles (EA). Materials and methods: A retrospective evaluation of records and radiographs of 90 patients scheduled for single implant therapy at the molar region over a period of up to 10 years after prosthetic restoration was performed. The radiographic MBL and clinical parameters were measured over time and statistically analyzed. Results: LMS implants presented a statistically significant higher cumulative success rate (97.7 % vs. 91.1%. p<.05) and lower mean MBL compared to noLMS (0.8mm vs. 1.7 mm, p<.05). Around noLMS BL implants an EA.
