Abstract

Osseointegrated endosseous implants have been widely used and become a predictable treatment option for completely and partially edentulous patients. The viability and predictability of this treatment modality have been supported with the high success rates in numerous studies. Clinical guideline requires a healing period of 3 to 6 months without functional loading to achieve osseointegration with machine surface implants. Therefore, numerous studies on immediately loaded implants have been conducted in an attempt to minimize or eliminate this healing period. The purpose of this study was to evaluate the success rate of the immediately provisionalized oxidized-surface implants in healed sites supporting maxillary single premolars. The marginal bone changes at different time interval were also assessed.

Ten subjects with missing single maxillary premolar were enrolled in this study. Each subject received a fixed provisional prosthesis at the time of implant placement surgery, and definitive metal-ceramic prosthesis were placed 6 months later. Each subject was evaluated clinically and radiographically at 1-, 3-, 6-, and 12-months after implant placement. Data was collected and analyzed using repeated measures analysis of variance (ANOVA) at a significant level of α=.05.

At 12 months after implant surgery, all implants (10/10) remained osseointegrated. The mean marginal bone change from the time of implant placement to 12 months post surgery was -0.44 mm. No surgical and prosthodontics complications were observed.

The results of this study suggest that favorable implant success rate and marginal bone change can be achieved with immediate provisionalization of threaded oxidized implants in single maxillary premolars healed sites.
