Advantages and feasibility of prefabricated PEEK crowns for aesthetic restoration in primary teeth.

ABSTRACT: Objectives The main purpose of this study is to evaluate the efficacy of polyetheretherketone (PEEK) as a material for prefabricated crown restorations in pediatric dentistry, particularly for restoring primary tooth structure defects. Materials and methods This study analyzed the effects of three surface treatment modalities on PEEK's surface morphology, wettability (as measured by contact angle), and shear bond strength. These treatments included alumina (Al₂O₃) sandblasting alone, and in conjunction with a 98% sulfuric acid pretreatment. Subsequently, an evaluation was conducted to assess the compressive and fatigue properties of self-fabricated PEEK preformed crowns, preformed metal crowns, and preformed zirconia crowns. Results Al₂O₃ sandbla
