ABSTRACT

The purpose of the present clinical study was to evaluate the influence of Laser-Lok® microtexturing surface on clinical attachment level and crestal bone remodeling around immediate functional loaded implants in single-tooth replacement in the area of 15–25 and 35–45.

MATERIALS AND METHODS

Seventy-seven patients were included in a prospective, randomized study and divided in two groups: in the control group BioHorizons Tapered Internal non-Laser-Lok®-type (NLL; n=39) implants were used, while in test group BioHorizons Tapered Internal Laser-Lok®-type (LL; n=39) was used. Crestal bone loss (CBL), and clinical parameters including clinical attachment level (CAL), plaque index (PI), and bleeding on probing (BOP), were recorded at baseline examinations (BSL) and 6 (T1), 12 (T2), and 24 months (T3) after loading with the final restoration.

RESULTS

One implants was lost in the control group, and one in the test group, giving a total survival rate of 96,1% after 2 years. PI and BOP outcomes were found similar for both implant types without statistical differences. A mean CAL loss of 1.10mm ± 0.51mm was observed during the first 2 years in the NLL group, while the mean CAL loss observed in LL the group was 0.56mm ± 0.33mm. Radiographically, NLL group implants showed a mean crestal bone loss of 1.07mm ± 0.30mm compared to 0.49mm ± 0.34mm for the LL.

CONCLUSIONS

The type of implants did not influence the survival rate, whereas LL resulted in greater CAL and in shallower radiographic peri-implant CBL than NLL
