Influence of different scan body design features and intraoral scanners on the congruence between scan body meshes and library files: An in vitro study.

Statement Of Problem: Implant scan bodies (ISBs) present with a variety of features, including diverse design geometries and manufacturing materials. How these features influence the congruence between the clinically obtained mesh file and the software-based library file of the scan body during the alignment stage within the computer-aided design (CAD) software program is unclear. It is also uncertain how these features influence the scanning accuracy of different scanners.

A comprehensive review and update on the current state of computer-assisted rehabilitation in implant dentistry.

Aim: This paper provides a comprehensive review of the established concepts and newer developments related to computer-assisted implant rehabilitation.

Methods: Two independent researchers searched the English literature published to 31st December 2023 in the PubMed/Medline database for primary and secondary research and related publications on computer-assisted implant planning, computer-assisted implant placement and computer-assisted implant restoration.

Results: A total of 58,923 papers were identified, 198 relevant papers were read in full text and 110 studies were finally included.

Complete Digital Restoration: Implant-Supported Prosthesis Using Rapid Prototyping and a Model-Free Approach.

This report presents a completely digital workflow utilizing digital intraoral scanning, rapid prototyping techniques, and a monolithic final restoration. A complete fixed prosthesis supported by six implants was used to replace a patient's periodontally compromised mandibular natural dentition. A staged approach was used in which a series of milled and 3D-printed provisional restorations were fabricated to help the patient transition to the dental implant rehabilitation.

Using the surgical guide for impression-free digital bite registration in the edentulous maxilla-a technical note.

Studies reporting on the application of digital bite registration for fully edentulous patients rehabilitated with dental implants are scarce. This article describes a technique for intraoral digital registration of the occlusal vertical dimension in a fully edentulous maxilla to be rehabilitated with a fixed implant prosthesis. Following fully guided placement of six maxillary implants, the surgical stent duplicating the existing upper full denture was securely fixed on two anterior implants and sectioned along the center line of the hard palate.
