Abstract

Purpose: To evaluate posterior screw-retained customized PEEK abutments/crowns on a Ti base and compare them to porcelain fused to metal (PFM) crowns on ready-made abutments supported by short implants in terms of stability and marginal bone loss. Materials and Methods: Twelve patients (N=12) with missing posterior teeth indicated for short dental implants were selected based on the pre-established inclusion and exclusion criteria, and randomly divided into two equal groups (n=6) according to the type of implant superstructures. Group (1): Customized PEEK abutment/crowns and group (2): Prefabricated titanium abutment/PFM crowns. Patients were evaluated for stability and marginal bone level immediately after implant placement, immediately after loading, and then after 3, and 6 months. Accordingly, marginal bone loss was calculated. Data was collected, arranged, and tabulated for statistical analysis. Results: Group (2) recorded statistically insignificantly higher implant stability at primary and 0-month intervals than group (1), while at 3- and 6-month intervals group (1) recorded higher stability than group (2). The difference was statistically significant at the 6-month interval. Regarding marginal bone loss, group (1) recorded a statistically significantly less bone loss than group (2) at different intervals. Conclusion: By time, customized posterior PEEK abutments supported by short implants have a significant positive effect on implant stability and marginal bone loss. The customized PEEK abutments constitute an effective alternative to titanium abutments.
