Modelos odontológicos digitais: o fim da era do modelo de gesso

Abstract

Significant advances have been taking place in the dental environment with the implementation of technologies such as digital scanning, whose success and agility in diagnosis and treatment planning requires precise information. Digital models are increasingly present in the reproduction of dental arches and the relationship between them, thus facilitating the clinician's decision-making. Thus, the aim of this study is to approach, through a literature review, the use of digital models and their methodology for obtaining them in the dental office, highlighting the advantages, disadvantages, indication and contraindication of this technique. For that, a narrative literature review was carried out, with a descriptive approach, carried out through searches in online databases, in English and Portuguese. It was observed that scanning with intraoral scanners has become increasingly accurate and simple to handle, causing minimal discomfort to the patient and skipping steps in relation to conventional impression, reducing the need to maintain stocks of impression material, speeding up all diagnosis and planning and with a proven accuracy. Despite being a recent technology that still has a high cost of implementation in the dental office, there is a tendency to popularize the technique, making the intra-oral scanner, the use of software and 3D printers items present in the clinic's daily life, reducing each the need and use of traditional plaster models is increasing.
