Article Synopsis
- This study reviews the current applications, limitations, and challenges of using polyetheretherketone (PEEK) in stomatology, highlighting its importance in various dental procedures.
- Numerous studies underscore PEEK's beneficial properties, such as biocompatibility and fracture resistance, and its use in many dental applications, including implants and orthodontic devices.
- Despite its potential, most evidence is based on short-term studies, indicating a need for more long-term clinical research to fully support PEEK's effectiveness in dentistry.
Clinical Acceptance of Digitally Produced Zirconia and Metal Post and Cores, Based on the Impression Method.

Department of Prosthodontics, Carol Davila University of Medicine and Pharmacy, 032799 Bucharest, Romania.
Background: The existing literature predominantly examines post and core assessments post-cementation, neglecting the critical pre-cementation phase. Research on the clinical acceptance of dental posts received from dental laboratories before cementation is notably lacking. This study investigates the percentage of zirconia and metal dental posts that are deemed suitable for cementation by clinicians, among the total received from the dental laboratory.

Statement Of Problem: How resin-based material and a light-activation protocol influence the mechanical properties of materials used to cement glass fiber post-and-cores in endodontically treated teeth is unclear.
Purpose: The purpose of this in vitro study was to evaluate the influence of immediate or 5-minute delayed light activation on the mechanical properties of dual-polymerizing resin cements and dual-polymerizing resin-core materials compared with bulk-fill composite resins.
Material And Methods: Nine resin-based materials were tested: 4 dual-polymerizing resin-core materials, (Allcem Core; FGM, LuxaCore Z; DMG, Rebilda DC; VOCO, and (Clearfil DC Core Plus; KURARAY), 3 dual-polymerizing resin cements, (RelyX Universal; 3M ESPE, RelyX U200; 3M ESPE, and Allcem Dual; FGM), and 2 bulk-fill composite resins, (Opus Bulk Fill APS; FGM, and Filtek One Bulk Fill; 3M ESPE).

Electronic address:
Statement Of Problem: Applications of polyetheretherketone (PEEK) as a promising alternative to ceramic materials have extended to include post-and-cores. However, information regarding the available fabrication techniques for producing custom-made PEEK post-and-cores and their effect on accuracy is still scarce.
Purpose: The purpose of this in vitro study was to evaluate the trueness and intaglio fit of custom-made PEEK post-and-cores fabricated using different techniques.
