Evaluation of Accuracy and Position of Milled and 3D-Printed Teeth in Digital Complete Dentures.

Purpose: To compare the accuracy of milled versus 3D-printed complete denture bases and teeth and to assess the position of the teeth in relation to the corresponding denture bases.

Materials And Methods: Two different manufacturing techniques were used in this study. In Group A, 10 complete dentures were digitally designed and fabricated by milling prepolymerized blocks of polymethyl methacrylate (PMMA).

A Comparison of Denture Base Retention and Adaptation Between CAD/CAM and Conventional Fabrication Techniques.

Purpose: To assess the retention and adaptation of milled and printed denture bases in comparison to conventional ones.

Materials And Methods: A total of 24 completely edentulous patients were selected. For each patient, three maxillary denture bases were constructed according to different fabrication techniques, thus defining the three groups for comparison: group 1 consisted of denture bases constructed by a conventional technique, group 2 consisted of denture bases milled from prepolymerized blocks of PMMA, and group 3 consisted of denture bases fabricated by a 3D printing technique.

Assessment of tooth positions of printed complete dentures with different designs and tooth positioning techniques.

Purpose: To evaluate the accuracy of tooth positions in printed complete dentures with different designs and teeth positioning techniques.

Materials And Methods: Five different designs of complete dentures and teeth positioning techniques were evaluated in this in vitro study. In Group I, the denture bases and teeth were designed as a single piece.

Customized scan bodies to facilitate intraoral scanning for full arch implant prosthesis: A dental technique.

This article presents the design of customized resin scan bodies with different forms and their use to facilitate intraoral scanning of a maxillary full arch implant case with five implants. The aim is to limit the distance between the scan bodies and to create definite landmarks to facilitate the scanning process in full arch implant cases.

Evaluation of the Accuracy and Adaptation of BioHPP Removable Partial Denture Frameworks Constructed by Milling vs the Pressing Technique.

Purpose: To evaluate the accuracy and adaptation of BioHPP removable partial denture frameworks constructed from milling vs the pressing technique.

Materials And Methods: This in vitro study was applied on an educational maxillary stone model with bilateral bounded saddles. Two different manufacturing techniques were used, and thus two groups were defined: (1) the pressed group, in which 20 BioHPP frameworks were constructed by milling a castable resin that was pressed into BioHPP using the lost wax technique; and (2) the milled group, in which 20 BioHPP frameworks were constructed directly by milling the BioHPP blanks.

Subtractive versus additive indirect manufacturing techniques of digitally designed partial dentures.

Purpose: The purpose of this study was to evaluate the accuracy of digitally designed removable partial denture (RPD) frameworks, constructed by additive and subtractive methods castable resin patterns, using comparative 3D analysis.

Materials And Methods: A Kennedy class III mod. 1 educational maxillary model was used in this study.

Retention of a telescopic overdenture on customized abutments after the simulation of 1 year in function.

Background: Telescopic implant-retained overdentures are considered one of the most common treatment modalities for edentulous patients.

Objectives: The aim of the study was to evaluate the retention of a BioHPP (biocompatible highperformance polymer) telescopic overdenture supported by customized abutments made from 2 different materials after the simulation of 1 year in function.

Material And Methods: Twelve models of a completely edentulous mandible were three-dimensionally (3D)-printed.
