Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Effect of margin thickness and cement gap on the fabrication and fit accuracy of additively manufactured crowns in definitive resins with different filler content

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how commercially available composite resins in varying filler content affect the fabrication and fit accuracy (trueness and precision) of additively manufactured (AM) definitive crowns with different margin thickness and cement gaps by comparing them to subtractively manufactured (SM) polymer‐infiltrated ceramic crowns ...

Microleakage assessment of a resin based sealant after acid etching and Er: YAG laser treatment: An in vitro study [PDF]

Stomatološki glasnik Srbije, 2019
Introduction Marginal adaptation of sealants is important element in prevention of dental caries. The failure of marginal adaptation leads to marginal leakage, passage of bacteria, fluids, molecules or ions between enamel and sealant, creating ...

Soft‐Tissue Integration of Dental Implants: Formation, Maintenance, and Relevance for Peri‐Implant Health

Journal of Periodontal Research, EarlyView.
Sixty years after the introduction of dental implants, it is clear that soft‐tissue integration is as essential as osseointegration. This review outlines how peri‐implant soft tissues develop, protect, and sometimes fail, revealing key knowledge gaps and new opportunities to improve long‐term implant stability.
