J Prosthet Dent 2024:S0022-3913(24)00279-8. [PMID: 38658250 DOI: 10.1016/j.prosdent.2024.04.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 04/03/2024] [Accepted: 04/04/2024] [Indexed: 04/26/2024]
Abstract
Assessing the correlation between the current restorative space and the target restorative space is important in determining whether additional tooth preparation is required when replacing failed prostheses. However, existing techniques are not always accurate or efficient. This article describes a digital workflow for the accurate chairside evaluation of the current restorative space and nontemplate-guided tooth preparation. Reference data was obtained from an initial scan of the existing restoration with an intraoral scanner. After removing the existing restoration, a second scan of the tooth was made and compared with the reference data to evaluate the current restorative space. Subsequently, the abutment tooth was prepared and rescanned, with the restorative space being re-evaluated until it met the requirements. This workflow enables the immediate and accurate evaluation of the restorative space, facilitating accurate chairside tooth preparation without the need for silicone indices or other templates, thereby saving time and cost.

Abstract
AIMS Distance between dentistry and medicine is a traditional and historical obstacle that affects multiple levels of the health system, especially the health policies to improve health service quality. Changes in dental education, especially involving the adoption of integrative health models in professional development, are considered essential for reducing this gap. We aimed to show a dental curriculum focused on special care as a tool for medicine-dentistry integration. METHODS In this study, we present a new proposal for an undergraduate dental curriculum in which topics related to special care are addressed transversally and are the core for interdisciplinary integration of oral health with systemic health. We also describe how themes related to dental home care and hospital dentistry were included in this course as basic professional competencies. RESULTS AND CONCLUSION This initiative is aligned with the global trend to adopt educational systems that contribute to the reduction of health care inequalities and improve health service quality.

MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59010116. [PMID: 36676740 PMCID: PMC9861456 DOI: 10.3390/medicina59010116] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Revised: 12/20/2022] [Accepted: 12/30/2022] [Indexed: 01/09/2023]
Abstract
Background and Objectives: 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. Materials and Methods: 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. Three-dimensionally printed simulated dental models can subsequently be manufactured based on the previously obtained digital models. The opinion of a group of undergraduate dental students (n = 205) on the proposed method was assessed via a questionnaire, administered as a Google form, sent via email. Results: The modular digital models allow students to perform repeated virtual simulations of any possible partial edentulism cases, to project 3D virtual treatment plans and to observe the subtle differences between diverse teeth preparations; the resulting 3D-printed models could be used in students' practical training. The proposed method received positive feedback from the undergraduate students. Conclusions: The advanced method is adequate for dental students' training, enabling the gradual design of modular digital dental models with partial edentulism, from simple to complex cases, and the hands-on training on corresponding 3D-printed dental models.
