Comparative Evaluation of Temporomandibular Disorders and Dental Wear in Video Game Players.

: The increasing prevalence of video gaming has raised concerns about its potential impact on musculoskeletal health, particularly temporomandibular disorders (TMDs). This study aims to compare TMD symptoms, mandibular function, and dental wear between gamers and non-gamers among university students. : An observational study included 108 students aged 20 to 23 years, divided into gamers (n = 48) and non-gamers (n = 60).

Clinical Acceptance of Digitally Produced Zirconia and Metal Post and Cores, Based on the Impression Method.

Background: The existing literature predominantly examines post and core assessments post-cementation, neglecting the critical pre-cementation phase. Research on the clinical acceptance of dental posts received from dental laboratories before cementation is notably lacking. This study investigates the percentage of zirconia and metal dental posts that are deemed suitable for cementation by clinicians, among the total received from the dental laboratory.

Methods of postural analysis in connection with the stomatognathic system. A systematic review.

This systematic review aimed to identify the main tools used to analyze the relationship between the postural and stomatognathic systems. The study followed the PRISMA guidelines, and data were collected from Science Direct and PubMed databases to identify articles published until December 2022. After applying inclusion and exclusion criteria, 26 articles were selected from the initial 903 articles.

Fully digital workflow for retrofitting a new crown to an existing removable partial denture.

A fully digital technique for retrofitting a new crown to a removable partial denture (RPD) is presented. The conventional crown preparation was followed by intraoral scanning of the preparation, the antagonists, and the occlusal relationship and by scanning the RPD both in situ and outside the oral cavity. All the standard tessellation language (STL) files were indexed in a design software program, and the new crown was designed.

Modular Digital and 3D-Printed Dental Models with Applicability in Dental Education.

: The ever more complex modern dental education requires permanent adaptation to expanding medical knowledge and new advancements in digital technologies as well as intensification of interdisciplinary collaboration. Our study presents a newly developed computerized method allowing virtual case simulation on modular digital dental models and 3D-printing of the obtained digital models; additionally, undergraduate dental students' opinion on the advanced method is investigated in this paper. : Based on the digitalization of didactic dental models, the proposed method generates modular digital dental models that can be easily converted into different types of partial edentulism scenarios, thus allowing the development of a digital library.

Compressive and Flexural Strength of 3D-Printed and Conventional Resins Designated for Interim Fixed Dental Prostheses: An In Vitro Comparison.

A provisionalization sequence is essential for obtaining a predictable final prosthetic outcome. An assessment of the mechanical behavior of interim prosthetic materials could orient clinicians towards selecting an appropriate material for each clinical case. The aim of this study was to comparatively evaluate the mechanical behavior-with compressive and three-point flexural tests-of certain 3D-printed and conventional resins used to obtain interim fixed dental prostheses.

Biochemical Interaction between Materials Used for Interim Prosthetic Restorations and Saliva.

The purpose of this study was to analyze the oxidative stress level and inflammatory status of saliva in the presence of certain materials used for obtaining interim prosthetic restorations. Four types of interim resin materials were investigated: a pressure/heat-cured acrylic resin (Superpont C+B, SpofaDental a.s Czech Republic, /KaVo Kerr Group), a milled resin (Telio CAD polymethyl methacrylate, Ivoclar Vivadent AG, Liechtenstein), a 3D printed resin (NextDent C&B MFH, NextDent by 3D Systems, the Netherlands), and a pressure/heat-cured micro-filled indirect composite resin (SR Chromasit, Ivoclar Vivadent AG, Liechtenstein).

Biologic and Esthetic Outcome of CAD/CAM Custom Ceramic Implant Abutment: A Clinical Report.

A prerequisite of a functional and esthetical implant-supported crown is a proper surgical planning and an abutment with a design and color that maintain the initial soft-tissue contour. This clinical report describes the use of a custom ceramic implant abutment designed with computer-aided design and computer-aided manufacturing (CAD/CAM) technology. A zirconia framework was milled and cemented extra orally to a prefabricated titanium base, the new custom abutment being both precise and esthetic.
