Monolithic zirconia restorations increasingly have been used in dental practice in recent years and demonstrate superior mechanical performance compared with porcelain-veneered zirconia restorations. Recent advances in manufacturing technology have made possible the fabrication of translucent monolithic zirconia ceramics. This case report describes three clinical examples of monolithic zirconia fixed dental prostheses being used in the anterior and posterior regions and exhibiting acceptable esthetic results.

Objectives: The aim of this randomised controlled trial was to assess clinical, radiographic and patient reported outcomes of narrow versus standard diameter titanium zirconium (TiZr) implants supporting single crown restorations in posterior sites with limited bone width.
Materials And Methods: Participants requiring replacement of single missing posterior teeth with implant-supported crowns were randomly allocated into 2 treatment groups: narrow (3.3 mm) or standard (4.

Background: The growing demand for esthetic restorative materials highlights the need to evaluate their marginal accuracy and fracture resistance to ensure optimal clinical outcomes for primary molars.
Aim: The aim was to assess the vertical marginal gap distance and fracture resistance of esthetic restorative materials after cyclic loading.
Design: Forty extracted primary molars were randomly divided into four groups: Group I, stainless steel veneered crowns with tooth-colored material; Group II, prefabricated monolithic zirconia crowns; Group III, yttria-partially stabilized zirconia computer-aided design/computer-aided manufacturing (CAD/CAM) crowns; and Group IV, hybrid ceramic CAD/CAM crowns.

Objective: The use of vertical margin design in all-ceramic restoration has generated inquiries regarding its clinical efficacy under diverse dynamic oral conditions. This research aims to assess the marginal fit and fracture resistance of monolithic zirconia crowns featuring vertical margin design as opposed to those with conventional horizontal margin design.
Materials And Methods: Two metal dies were employed to generate replicated resin dies mimicking mandibular first molar preparation.

Highly translucent zirconia (TZ) is frequently used in dentistry. The properties of several highly translucent zirconia materials available in the market require an in-depth understanding. In this study, we assessed the translucency, crystalline phase, mechanical properties, and microstructures of three newly developed highly translucent zirconia materials (Zpex 4.

The present article describes a step-by-step maximally digitalized workflow protocol with computer-aided design and computer-aided manufacturing (CAD/CAM) in partial-arch edentulous patients rehabilitated with fixed dental prostheses and removable partial dentures (FDPs and RPDs). Facial digitalization, intraoral scans, and functional mandibular movement recordings were used to create a 4D virtual patient on commercially available CAD software. The fixed components including post-and-cores, both metal-ceramic with extra-coronal attachment and monolithic zirconia crowns, and the RPDs were manufactured by computer numerical controlled direct milling.
