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.

Adjunctive Nd:YAG laser irradiation in the treatment of stage III/IV periodontitis: a 12-month, randomized, controlled trial.

Objectives: The aim of this study was to evaluate the clinical efficacy of the adjunctive use of Nd:YAG laser (1064 nm) to full-mouth scaling and root planning (FMS), in stage III/IV periodontitis patients.

Materials And Methods: Sixty stage III/IV periodontitis patients were randomly assigned to three groups. The control group received FMS, laser 1 group received combined FMS/single Nd:YAG laser irradiation (3 W, 150 mJ, 20 Hz,100 μs), and laser 2 group received combined FMS/double Nd:YAG laser irradiation with 1-week interval (2.

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.

Histologic evidence of periodontal regeneration in furcation defects: a systematic review.

Objective: To systematically review the available histologic evidence on periodontal regeneration in class II and III furcations in animals and humans.

Materials And Methods: A protocol including all aspects of a systematic review methodology was developed including definition of the focused question, defined search strategy, study inclusion criteria, determination of outcome measures, screening methods, data extraction and analysis, and data synthesis. The focused question was defined as follows: "What is the regenerative effect obtained by using or not several biomaterials as adjuncts to open flap surgery in the treatment of periodontal furcation defects as evaluated in animal and human histological studies?"

Search Strategy: Using the MEDLINE database, the literature was searched for articles published up to and including September 2018: combinations of several search terms were applied to identify appropriate studies.
