“…Bergamo et al 66 evaluated the effect of aging on the adaptation of zirconia abutments in the implant-abutment connection using two different methods on the and aimed to predict the survival possibility of anterior crowns supported by straight and angled abutments. Abutments were randomly divided into three experimental groups according to their laboratory aging state control, autoclave aging and hydrothermal reactor aging.…”

Today, the use of micro-computed tomography is becoming widespread in almost every field of dental research. When the national review articles on micro-computed tomography are examined, it is seen that the focus is on endodontic and surgical dental applications. As prosthodontists, our article, which was compiled in order to deepen the specific usage areas of micro-computed tomography applications and to review the studies done in this area, provides information about the use of micro-computed tomography method in prosthetic dentistry. Micro-computed tomography is a powerful in vitro research method. Micro-computed tomography was used; marginal and internal compatibility of restorations, cement spacing of restorations, adaptation of denture bases, accuracy of prosthetic measurements, effects of occlusal irregularities, volumetric changes in teeth due to dental post application, biomechanical evaluation of implant-abutment connection, and compatibility of maxillofacial prostheses.

“…However, as a mechanical complication, fractures of zirconia abutments were observed more frequently than titanium abutments 7,8) . Additionally, the susceptibility of zirconia to aging and low-temperature degradation may reduce its strength and toughness 9,10) , as zirconia abutments directly contact the oral environment.…”

Fracture strength of implant-supported hybrid abutment crowns in premolar region fabricated using different restorative CAD/CAM materials

et al. 2023

The present study investigated the fracture strength of hybrid abutment crowns (HACs) in the premolar region that were fabricated with different restorative computer-aided design/computer-aided manufacturing (CAD/CAM) materials. The abutment-implant structures were randomly assigned into four groups (n=11 per group): bi-layered zirconia restorations (BL), translucent zirconia (4Y-PSZ) restorations (TZ), lithium disilicate ceramic restorations (LD), and dispersed nanoparticle-filled composite resin restorations (CM). All restorations were adhesively bonded to the titanium abutments. After the restoration-abutment complex was tightened onto the implant, the fracture strength was measured. The TZ (2.06 kN) and LD (1.87 kN) groups had significantly higher median fracture strengths than the BL (1.12 kN) and CM (1.10 kN) groups. In terms of fracture resistance, the 4Y-PSZ and lithium disilicate ceramic monolithic restorations would be superior to bi-layered 3Y-TZP and composite resin monolithic restorations for HACs in the premolar region.
