Abstract

Objectives: This retrospective study was aimed to compare the clinical and radiographic outcomes of implants with the same body design but different collar surface (laser-microtextured vs. not laser-microtextured) after functional loading.

Materials and methods: Forty-three patients (29 females, 14 males) with 139 implants (60 laser-microtextured and 79 without laser microtexturing) were included in this study. Patients were consecutively included, and the data were collected during their implant maintenance visit. Clinical and radiographic parameters including probing depth (PD), bleeding on probing (BoP), and marginal bone loss (MBL) were recorded. In addition, the implant success index (ISI) score was determined. Statistical analysis was performed using the Mann-Whitney U test, the Kruskal-Wallis rank test, or the Pearson χ2 test, along with binary logistic regression (p < 0.05 was considered to be statistically significant).

Results: The median post-loading follow-up was 24 months with 100% survival rate. There was no significant differences in terms of mean PD (3.01 mm vs. 2.63 mm), mean MBL (0.54 vs. 0.49 mm), BoP (56.7% vs. 53.2%), and ISI score between laser-microtextured collars and implants without laser microtexturing. Logistic regression revealed arch as a significant predictor of peri-implantitis (p = 0.02).

Conclusion: Within the limitations of this study, there was no statistically significant difference between the clinical and radiographic outcomes of implants with laser-microtextured and non-laser-microtextured collar designs. Clinical relevance Prospective studies with larger sample sizes and careful monitoring of implant placement protocols are needed for definite conclusions.
