Digital Denture

Utilization of computer-aided design/computer-aided manufacturing (CAD/CAM) rapidly increases in dental medicine. Making of computer-engineered complete denture is based on scanning of patient data, designing of prosthesis and milling or rapid prototyping. This is digital denture, term that includes innovative devices, software programmes and corresponding materials. Industrially polymerized cross-linked polymethyl methacrylate (PMMA) is the material used for fabrication of digital denture. The aim of this study is to analyze the different cross-linked PMMA used for fabrication of CAD/CAM complete denture.

Abstract Background Contemporary dentistry is advancing toward computer-aided design/ computer-aided manufacturing (CAD/CAM) technology. But the budding dentists are unaware about the advancement. This survey aims at detecting the level of awareness among the undergraduate students and then correlating those results to modify the future curriculum. Objective The study aims (1) to assess the awareness among the dental undergraduate students and (2) to correlate the level of awareness among the third years, final years, and interns. Sample Selection Study sample consist of 300 students (third year students, final year students, and interns) of A. B. Shetty Memorial Institute of Dental Sciences, Mangalore, Karnataka, India. The information of the survey was collected with the help of a questionnaire. Results More than 70% of the students were aware about the basic functioning of CAD/CAM unit and approximately 74% of the students were unaware about the materials used to fabricate the prosthesis using CAD/CAM technology.

The introduction of computer-aided design/computer-aided manufacturing (CAD/CAM) technology into complete denture (CD) fabrication ushered in a new era in removable prosthodontics. Commercially available CAD/CAM denture systems are expected to improve upon the disadvantages associated with conventional fabrication. The purpose of this report is to present the workflow involved in fabricating a CD with a traditional clinical recording method and CAD/CAM technology and to summarize the advantages to the dental practitioner and the patient.

Great emphasis has been attached to the achievement of productivity and producibility benefits through the application of computer-aided design and computer-aided manufacturing (CAD/CAM) technologies. To ensure the achievement of these benefits, it is important that the end user have appropriate software and be able to use it to his advantage. The proper procurement, customization, installation, training, and implementation of software can play a significant role in the effectiveness of CAD/CAM.

ABSTRACTObjective: To fabricate orthodontic brackets from esthetic materials and determine their fracture resistance during archwire torsion.Materials and Methods: Computer-aided design/computer-aided manufacturing technology (Cerec inLab, Sirona) was used to mill brackets with a 0.018 × 0.025-inch slot. Materials used were Paradigm MZ100 and Lava Ultimate resin composite (3M ESPE), Mark II feldspathic porcelain (Vita Zahnfabrik), and In-Ceram YZ zirconia (Vita Zahnfabrik). Ten brackets of each material were subjected to torque by a 0.018 × 0.025-inch stainless steel archwire (G&H) using a specially designed apparatus. The average moments and degrees of torsion necessary to fracture the brackets were determined and compared with those of commercially available alumina brackets, Mystique MB (Dentsply GAC).Results: The YZ brackets were statistically significantly stronger than any other tested material in their resistance to torsion (P < .05). The mean torques at failure ranged from 3467 g.mm for Mark II to 11,902 g.mm for YZ. The mean torsion angles at failure ranged from 15.3° to 40.9°.Conclusion: Zirconia had the highest torsional strength among the tested esthetic brackets. Resistance of MZ100 and Lava Ultimate composite resin brackets to archwire torsion was comparable to commercially available alumina ceramic brackets.

Introdução: O sistema CAD CAM (Computet Aided Design/Computer Aided Manufacturing) representa um grande avanço para a odontologia restauradora e protética. Inserido na odontologia na década de 70, sofreu constantes aperfeiçoamentos, e recentemente tem sido empregado na confecção de próteses totais. O presente trabalho busca discutir o uso desse sistema para confecção de próteses totais, além de apresentar as técnicas para tal, vantagens e desvantagens e comparar brevemente com a técnica manual. Metodologia: Revisão discutida da literatura, realizada por meio da análise de estudos de casos clínicos, revisões narrativas da literatura, teses e dissertações, que estivessem na língua inglesa ou portuguesa. Foram utilizadas as bases de dados PubMed e LILACS, utilizando os descritores: “CAD CAM “, “complete denture” e “digital”. O operador booleano “AND” foi utilizado associado aos descritores. Foram selecionados 32 estudos para análise de 1994 a 2021. Resultados: O sistema CAD CAM é composto por: scanner, software e a unidade CAM fornecendo o escaneamento de um molde, modelo ou da própria cavidade oral. A obtenção das relações intermaxilares geralmente é feita através do método convencional com posterior escaneamento dos dados para manipulação e planejamento da futura prótese no software. Melhor retenção, resistência a fratura, menor contração de polimerização, liberação de monômeros, porosidade e tempo de cadeira, são benefícios dessa técnica. Conclusões: A confecções de próteses totais digitais apresenta futuro promissor na odontologia, todavia, limitações referentes ao escaneamento, relações intermaxilares e acessibilidade, são uma realidade. Faz-se assim, necessário mais estudos sobre tal temática.

Advances in computer technology opened new horizons in teaching Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) technologies. This paper will report the outcomes of two current NSF grants, 0311586 and 0302314, funded on Rapid Prototyping (RP) curriculum development. The objective of these RP projects is to provide advanced instruction and laboratory practices in the areas of CAD/CAM/CAE through challenging laboratory assignments and industrial projects that are integrated into any engineering curriculum. These projects create web-based materials, and also adapt and implement RP experiences and educational practices following successful similar models at various engineering schools to enhance pedagogy in design and manufacturing curriculum. Enhanced RP capabilities enable the students to build physical models directly from CAD data, where the prototype communicates important information about parts, including engineering data such as fit and limited functional testing, labeling, highlighting, and appearance simulation. Developed RP labs are used in junior and senior level design and manufacturing courses, including the senior capstone courses.
