Implant Stability Development of Photofunctionalized Implants Placed in Regular and Complex Cases: A Case-Control Study

Abstracts

The objective of this study was to compare the rate of implant stability development of as-received and photofunctionalized dental implants in regular and complex cases. Forty-nine implants (24 as-received and 25 photofunctionalized) placed in regular or complex cases were studied. Photofunctionalization was performed by UV-treatment of implants for 15 minutes immediately prior to placement. Implant stability was evaluated by measuring implant stability quotients (ISQ) at placement (ISQ1) and at second-stage surgery (ISQ2). The rate of implant stability development was evaluated by calculating the osseointegration speed index (OSI), defined as (ISQ2-ISQ1)/healing time in months. The average OSI was greater for photofunctionalized implants (3.7 ± 2.9) than for as-received implants (0.0 ± 1.0). The OSI in complex cases was 4.2 ± 3.2 for photofunctionalized implants and 0.2 ± 0.9 for as-received implants. In multivariant analysis, photofunctionalization showed the strongest influence on OSI for both regular and complex cases. Photofunctionalization accelerated the rate and enhanced the final level of implant stability development compared to as-received implants, particularly for implants placed into poor-quality bone and other complex cases. Photofunctionalization was a stronger determinant of implant stability than all other implant- and host-related factors.
