Crestal Bone and Soft Tissue Stability Surrounding Laser Microtextured Collar of Dental Implant; A 3-Year Clinical and Radiographic Evaluation

Abstract

Objective: To evaluate marginal bone level (MBL) and clinical performance of dental implants with laser microtextured collar after three years of loading. Material and Methods: Randomly selected were 24 patients (mean age ± standard deviation [SD] 44.0 ± 11.1 years) who had dental implants in the dental center at the Arab American University in Ramallah, Palestine. 64 implants are necessary to achieve 99% confidence level with a margin of error 0.1mm. Periapical radiographs were taken for these dental implants immeadiatly after loading and 3-years after loading. Crestal bone resorption was evaluated taking into consideration the attached gingivae width. Probing pocket depth and bleeding scores were also evaluated. Results: After 3 years of loading, the crestal bone loss was 0.74 ± 1.06 SD. Probing pocket depth 3.73 ± 0.85 SD. Gingivitis index (Bleeding on probing 0.77 ± 0.86 SD). Plaque index 0.40 ± 0.76 SD. In addition, no significant differences (P = 0.708) related to the attached gingiva width and radiograpgic bone loss were observed. Conclusion: Laser microtexturing of the collar of the dental implants provide stability of hard and soft tissue around dental implants. Nevertheless, it did not eliminate crestal bone resorption. Within the limits of this study, the laser microtexuring can stabilize the soft tissue regardless of the width of attached ginigiva.
