Zirconia crown has been widely used in the field of prosthodontics. Traditional zirconia exhibits excellent mechanical properties but lacks translucency. The introduction of transparent zirconia significantly enhances its aesthetic performance. In clinical applications, factors affecting the aesthetic results of full zirconia crown should be comprehensively considered, and the most suitable restoration should be chosen. Additionally, clinicians need to design appropriate tooth preparation dimensions and methods based on an individual patient's actual situation. During the clinical bonding process of zirconia, proper surface treatment of the tooth and restoration is essential. The selection of suitable adhesives is crucial for achieving optimal bonding strength and aesthetics.

Statement Of Problem: Despite high survival rates of implant-supported single crowns, retention loss remains common and decementation of crowns can compromise long-term stability, patient satisfaction, and treatment costs. Limited long-term evidence on cement type, abutment design, and materials requires further research to optimize clinical outcomes.
Purpose: The aim of this retrospective clinical study was to analyze the survival and decementation rates of zirconia and metal-ceramic implant-supported crowns in combination with different abutments (prefabricated or custom and unabraded or airborne-particle abraded).

Introduction: This study investigated the effect of sandblasting time and primer type on the shear bond strength of composite attachments to full-contour zirconia crowns.
Methods: A total of 108 zirconia specimens were fabricated and divided into 9 groups (n = 12) according to sandblasting time (10, 30, and 60 seconds) and primer type (silane, 10-methacryloyloxydecyl dihydrogen phosphate [MDP], universal). After sandblasting with 110-μm alumina particles, specimens were primed, and attachments were bonded using a packable composite.

Purpose The aim of this study was to assess the effectiveness of a PEEK (polyether-ether-ketone) ultrasonic tip in the cleaning around implant-supported restorations and to evaluate the effect of different cement types on the amount of residual cement at the restoration margins.Materials and methods A master model with an implant analogue placed in the upper left first premolar region was used to create 72 cast models and zirconia crowns were fabricated for each model. A total of 72 zirconia crowns were divided into two main groups based on the cleaning method applied after cementation.

Background: Short clinical crowns/abutments (SCC) pose a challenge in achieving adequate retention. Auxiliary retentive features (ARF), such as grooves, are commonly employed to enhance retention. The marginal gap (MG) and internal fit (IF) of restorations are critical factors influencing clinical success.

Fixed prosthetic restorations, particularly those made entirely of zirconia, are widely used in clinical dental practice for the restoration of natural teeth. Their success largely depends on the design of the tooth preparation, especially the type of finish line, as well as the restoration's ability to withstand occlusal forces during mastication. Over 12 months, a total of 21 extracted teeth were initially collected, from which six were selected for this study.
