Background:
The long-term success of dental implants is strongly influenced by peri-implant soft tissue attachment and maintenance of crestal bone. Laser microtextured collar implants are designed to enhance epithelial and connective tissue adhesion, potentially improving biological seal, and reducing marginal bone loss.
Materials And Methods:
A total of 40 patients requiring single posterior mandibular implants were recruited and randomly allocated into two groups (n = 20 each): Group A (laser microtextured collar implants) and Group B (machined collar implants). Clinical parameters such as probing depth (PD), bleeding on probing (BOP), and peri-implant mucosal thickness were assessed at baseline, 6 months, and 12 months. Radiographic assessment of crestal bone level changes was performed using standardized digital periapical radiographs. Data were analyzed using independent t-tests and repeated measures ANOVA (α = 0.05).
Results:
At 12 months, Group A showed significantly lower mean PD (2.1 ± 0.3 mm) compared to Group B (2.8 ± 0.4 mm, P < 0.001). BOP was observed in 10% of sites in Group A and 35% in Group B (P = 0.04). The mean crestal bone loss in Group A was 0.39 ± 0.11 mm, significantly lower than 0.74 ± 0.14 mm in Group B (P < 0.001).
Conclusion:
Laser microtextured collar implants demonstrated superior soft tissue integration and reduced crestal bone loss compared to conventional implants, suggesting their potential benefit in enhancing peri-implant tissue stability and implant longevity.
