A Simplified Technique for the Fabrication of Esthetic and Functional Space Maintainers in Pediatric Dentistry

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Introduction Premature loss of primary molars remains a frequent clinical problem in pediatric dentistry and may lead to space loss, occlusal disturbances, and the need for future orthodontic intervention. Conventional space maintainers, such as the band‐and‐loop appliance, are effective in preserving arch length but do not restore occlusal ...

Influence of Airborne‐Particle Abrasion and Thermal Cycling on Enamel Bond Strength and Roughness of Lithium Disilicate Treated With a Self‐Etching Ceramic Primer

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study investigated the effect of a self‐etching ceramic primer (Monobond Etch & Prime [MEP]), with or without aluminum oxide airborne‐particle abrasion, on the surface roughness, and microtensile bond strength (μTBS) of lithium disilicate bonded to enamel, compared with the conventional hydrofluoric acid plus silane (HF

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 ...

Effect of material, prosthesis height, and aging on the fracture strength of additively and subtractively manufactured implant‐supported cantilevered prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant‐supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.
