| Περίληψη: | Purpose: To retrospectively evaluate differences in marginal bone loss (MBL) between bone level (BL) implants with laser-microgrooved collar surface (LMS) and without laser-microgrooved collar surface (noLMS), restored with screw-retained single crowns with different emergence profiles (EPs) and emergence angles (EAs). 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 (0.8 vs 1.7 mm; P < .05) compared to noLMS. Around noLMS BL implants, an EA = 30 degrees (P < .05) and a concave EP (P < .05) showed a statistically significant correlation with reduced radiographic MBL. Around LMS BL implants, no statistically significant differences were found between different EAs or EPs. Conclusions: Different EAs and EPs have not been found to influence MBL in BL LMS implants. noMLS implants restored with a narrow EA = 30 degrees and a concave EP were associated with significantly less MBL over time.
