Aim To compare clinical and radiographic outcomes of implants with a Laser‐Lok®‐microtextured collar to implants with a resorbable blast textured ( RBT ) collar after a 5‐year follow‐up period. Materials and methods Thirty‐four implants with a Laser‐Lok®‐microtextured collar (test group [ TG ]) and 31 implants with an RBT collar (control group [ CG ]) were placed in 45 non‐smoking, periodontally healthy patients. The full‐mouth plaque score, full‐mouth bleeding score, number of sites with plaque, and the number of sites with bleeding on probing ( BOP ) were recorded at baseline, and at 1‐, 2‐, 3‐, 4‐, and 5‐year follow‐up. Probing depth ( PD ) and mucosal recession were assessed at baseline and after the 5‐year follow‐up period. The radiographic marginal bone loss ( MBL ) was calculated by subtracting the bone level at the time of crown insertion from the bone level at the 5‐year follow‐up. Results An implant survival rate of 94% and of 90% was reported for the TG and the CG , respectively. No statistical differences were found between the study groups for presence of plaque (10.1% vs. 25%) or for number of sites with BOP (10.3% vs. 23%). The differences between both study groups were statistically significant for mean MBL (0.81 ± 0.24 vs. 2.02 ± 0.32 mm), mean PD (2.32 ± 0.44 vs. 4.25 ± 0.87 mm), and mean mucosal recession (0.16 ± 0.3 vs. 0.22 ± 0.3 mm). Conclusions Within the limitations of this study, results suggest that the laser‐microtextured implant collar surface may provide more favorable conditions for the attachment of hard and soft tissues, and reduce the level of MBL .
