A high level of clinical skill is required for fabricating a provisional fixed partial denture with fiber-reinforced composite resin (FRC) using either the direct or chairside technique. The freehand approach to restoring missing teeth represents a challenge to the clinician, particularly when shaping and finishing a hygienic pontic. This technical report describes a simplified method for chairside fabrication of a fixed dental prosthesis with FRC. It is based on using a translucent template to guide the buildup procedure and to ensure optimal anatomy and function.

Objectives: This study aims to explore the effect of improving clinical efficiency by replacing traditional impression workflow with centralized digital impression workflow.
Methods: The department of prosthodontics in Center of Stomatology, Peking University Shenzhen Hospital has improved the clinical workflow by replacing the traditional impression made by doctors using impression materials for each patient with a centralized digital impression made by one technician for all patients in the department. This cross-sectional study recorded the chairside time required for impression taking in patients undergoing single posterior zirconia full crown restoration before clinical process improvement; the time required for centralized digital impression production; the comfort level of patients; and the adjacency relationship, occlusal contact relationship, and time required for prostheses adjusting (i.

Background: To minimize the risk of impaired osseointegration historically, it has been recommended to insert the implant into the bone (submerged implants) and to allow for submerged healing of 3-6 months in the lower and upper jaw, this conventional technique is advocated. The concept of nonsubmerged healing was introduced in 1988 in which gingival former was placed at the time of implant placement instead of cover screw. The treatment concept of nonsubmerged implant placement enables early implant loading, one surgical procedure only, and a reduced treatment period for the patients.

Background/purpose: The accuracy of intraoral scanners (IOSs) plays a crucial role in the success of final restorations in digital workflows. Previous studies have shown that numerous factors affect the accuracy of IOSs. Most studies have evaluated the accuracy of IOS under one restoration condition.

Objective: This study aimed to assess the fracture resistance of chairside computer assisted design and computer assisted manufacturing (CAD-CAM) lithium disilicate partial and full-coverage crowns and veneers for maxillary canines.
Methods And Materials: Forty-eight restorations for maxillary right canines (12 per group) were designed as follows: (1) partial crown with finish line in the upper middle third; (2) partial crown with finish line in the lower middle third; (3) traditional labial veneer; and (4) traditional full-coverage crown. Restorations were fabricated out of lithium disilicate (Amber Mill, Hassbio) using a chairside CAD-CAM system (Cerec Dentsply Sirona).
