A 6-year-old child with nonsyndromic oligodontia in the mixed dentition received a removable dental prosthesis with a polyetheretherketone framework and artificial gingiva, restoring esthetics and function. Computer-aided design and computer-aided manufacturing hemispherical glass-ceramic attachments were added to the teeth under the guidance of acid-etching and bonding guides to obtain an undercut area. The bonding and cementation of the attachments and the prosthesis delivery were completed in a single visit. This method offers a suitable prosthodontic treatment option for treating children with oligodontia in the mixed dentition.

Introduction The utilization of Computer-Aided Design and Computer-Aided Manufacturing (CAD/CAM) technology in the production of polyetheretherketone (PEEK) and acetal frameworks enhances the precision and stability of partial denture frameworks. This study evaluates the retentive forces of CAD/CAM-fabricated PEEK, acetal, and cobalt-chromium (Co-Cr) frameworks in removable partial dentures (RPDs). Methods Forty-five frameworks were fabricated (15 each of PEEK, acetal, and Co-Cr) and tested for retentive forces using a universal testing machine at a crosshead speed of 5 mm/min.

Background: The mechanical properties of framework materials significantly influence stress distribution and the long-term success of implant-supported prostheses. Although titanium, cobalt-chromium, zirconia, and polyether ether ketone (PEEK) are widely used, their biomechanical performance under dynamic loading conditions remains insufficiently investigated. This study aimed to evaluate the biomechanical behavior of four framework materials with different Young's modulus using dynamic finite element stress analysis.

Polyetheretherketone (PEEK) has emerged as a revolutionary material in modern dentistry because of its unique combination of mechanical strength, biocompatibility, and versatility. This literature review examines the current applications and future potential of PEEK in various dental disciplines. PEEK's favorable properties, including its low specific weight, high strength-to-weight ratio, and ability to be easily machined, have led to its adoption in prosthetics, implantology, and dental esthetic restorations.

Purpose: To evaluate the effects of various beverages on surface roughness and microhardness of PEEK and PEKK polymers.
Methods: Rectangular-shaped PEEK and PEKK polymers were fabricated and examined in the study. The specimens were immersed for 28 days at 37°C in red wine, coffee, and distilled water.
Purpose: The purpose of this study is to compare the stress distribution between all-on four and all-on six treatment concept with various prosthetics framework materials through finite element analysis.
Materials And Methods: A three-dimensional finite element model of edentulous maxilla was simulated using computerized topographical data of a patient. Four implants were placed according to All-on four concept.
