Evaluation of marginal accuracy of polyetheretherketone and zirconia copings fabricated using computer-aided design/computer-aided manufacturing technique: An in vitro study.

Aim: The aim of this study was to compare the marginal accuracy of polyetheretherketone (PEEK) and zirconia copings fabricated using computer-aided design/computer-aided manufacturing (CAD/CAM) technology, and to assess the impact of their material properties on accuracy when produced with a 4-axis milling system under controlled conditions.

Settings And Design: The study employed an in vitro design with a stainless steel die model featuring a 6 mm axial wall height, a 6-degree total occlusal convergence, and a radial shoulder finish line.

Materials And Methods: Thirty stone dies were created from silicone impressions of the metal die and poured using type-IV dental stone.

Prosthetic rehabilitation of edentulous hemimandibulectomy patient: a clinical report.

Surgical resection of mandible causes deviation of mandible toward affected side, resulting in loss of occlusal contact. This article presents twin rows of nonanatomic teeth on the untreated side of maxillary complete denture. The palatal row helps in mastication, whereas the buccal row supports the cheeks and improves the aesthetics.

Effect of simulated microwave disinfection on the mechanical properties of three different types of denture base resins.

Statement Of Problem: Disinfection of prostheses with chemical solutions has deleterious effects on dentures. The appropriate power setting of microwave for disinfection, without affecting denture base properties, is a controversy.

Purpose: To evaluate and compare the effect of simulated microwave disinfection at a recommended power setting on the mechanical properties of three denture base heat polymerized acrylic resins.
