Monolithic hybrid abutment crowns: Influence of crown height, crown morphology and material on the implant-abutment complex

Abstract

Monolithic restorative materials are increasingly being applied in modern prosthetic treatment concepts, owing to the digital transformation in dentistry and advances in computer-aided design and manufacturing (CAD-CAM) [1]. The range of options for clinicians is enormous, given the variety of available products with various material properties [2,3]. Most monolithic restorations are manufactured in a CAD-CAM process -subtractive or additive -that requires less time and effort as compared with conventionally veneered restorations, especially regarding the laboratory workflow; Joda et al. reported a single implant crown (SICs) treatment cost savings of 30% and a significant time reduction as compared to veneered crowns [4].CAD-CAM materials can be easily integrated into digital con-cepts[5], which will become increasingly important in the future due to ongoing digitalization [6]. In addition, many requirements of modern dentistry, such as favorable tooth-colored esthetics, exceptional physical properties, and excellent biocompatibility, can be met by tooth-colored monolithic restorative materials [2,3,[7][8][9].

Clinical performance and risk factors of all‐ceramic screw‐retained implant crowns in the posterior region based on a retrospective investigation

“…In addition, it is useful to be aware of potential risk factors for the survival and complication rates of restorations with TBAs that are often based on anatomical situations and only partially within the clinician's scope of influence. Exemplary, the vertical height of an implant crown can be mentioned as a potential risk factor due to high crown-to-implant (C/I) ratios and unfavorable leverage arms (Graf et al, 2024).…”
