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.

Wear behavior of pressable lithium disilicate glass ceramic [PDF]

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2015
AbstractThis article reports effects of surface preparation and contact loads on abrasive wear properties of highly aesthetic and high‐strength pressable lithium disilicate glass‐ceramics (LDGC). Abrasive wear testing was performed using a pin‐on‐disk device in which LDGC disks prepared with different surface finishes were against alumina pins at ...

Assessment of impact of a control die on marginal fidelity of milled zirconia crown copings for finishing and polishing

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated and compared the marginal fidelity of milled zirconia copings before and after finishing and polishing with and without a control die. Materials and Methods This prospective multicenter in vitro trial involved two methods regularly used in two clinics for hybrid and full‐digital workflows.

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 ...

Effectiveness of self‐etching ceramic primer on the bond strength of dental glass ceramics: A systematic review and meta‐analysis of in vitro studies on feldspathic and leucite‐reinforced ceramics

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review and meta‐analysis evaluated the bond strength effectiveness of a self‐etching ceramic primer, specifically Monobond Etch & Prime (MEP), compared to hydrofluoric acid with silane (HF+S) in feldspathic and leucite‐reinforced dental glass‐ceramics (DGCs). Materials and Methods This study followed PRISMA‐p guidelines

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?
