One-year Clinical Evaluation, Patient Satisfaction, and Adaptation of Milled (PEEK) Single Anterior Crowns Veneered with Two Different Techniques.

Abstract

Aim: The aim of the present study is to evaluate the patient satisfaction and marginal adaptation of milled BioHPP polyether ether ketone (PEEK) copings veneered with CAD/CAM composite resin and compare them to milled BioHPP PEEK copings veneered with manual layering.

Materials and methods: A total of 32 patients required anterior crowns to restore discolored, fractured, or maligned anterior teeth. Patients were divided into two groups according to the type of restoration used. The Comparator group included patients receiving milled BioHPP PEEK copings veneered with manual layering, while the intervention group was veneered with CAD/CAM composite resin. After final cementation, patient satisfaction and marginal adaptation were evaluated according to the rating score, and modified RYGE criteria respectively, after 6 and 12 months follow-up interval.

Results: Patient satisfaction results at baseline, the mean satisfaction scores were similar between groups, with no significant difference (p = 0.1536). After 6 months, scores increased in both groups, but the difference between groups remained non-significant (p = 0.0660). By 1 year, scores were identical between groups (means both 1.750), and marginal adaptation comparison between both groups (manual veneered) and (CAD/CAM veneered) revealed insignificant differences between both groups at T0, T1, T2.

Conclusions: After 1 year of follow-up, milled BioHPP PEEK copings veneered with manual veneering and CAD/CAM composite resin veneering, showed successful patient satisfaction, and marginal adaptation.

Clinical significance: The study may provide guidance for the clinicians to use this veneering technique to match shades that are clinically acceptable when esthetic is required with PEEK crowns good adaptation and easier modification.
