Escaneamento intraoral na terapia de fissura palatina: Desenvolvimento de um protocolo infantil associado à análise da imagem 3D em software livre

Abstract

Introduction: Cleft Palate (CP) is a congenital anomaly with a higher incidence of malformations that affect the face and oral cavity, characterized by a cleft that interrupts bone and / or palatal mucosa continuity. The treatment is of a surgical nature and, through anatomical variation of the fissure, it can be performed in stages. The rehabilitation process can be achieved using the three-dimensional (3D) image, through the intraoral scanner for copy and evaluation of the PF, due to its ability to reproduce the anatomical characteristics in detail. Choosing free and open source software optimizes the planning and surgical treatment of CP, as well as integrating rehabilitation costs. Aim: To develop a 3D intraoral scanning protocol for children with CP and to develop a protocol of commands in free and free software for intraoral image analysis in the Standard Tessellation Language (STL) format. Methods: This was an exploratory observational research, based on an integrative revision method of the literature added to a clinical case. Four steps were followed: (1) investigation of the current literature, (2) creation of a protocol for copying the CP in a child with an intraoral scanner, (3) execution of the protocol in a patient who will undergo a palatoplasty, (4) analysis and measurement crack in free and open source software. Results: The protocol developed to be effective and comfortable for recording CP, since it was developed based on an investigation of the literature associated with the priority of adapting the scan for the patient's age group. The measurement of the crack in the digital copy using free and free software is efficient and multifunctional, with the possibility of effectively assisting in the planning of the surgical rehabilitation Conclusion: With an execution of the scanning protocol, as a failure in the copy of the crack were minimized, the risk of aspirating impression material eliminated and the captured image stored to assist in the design of the patient's rehabilitation treatment. The results found were promising, since the applicability of free software to study the fissure, drives the use of health technologies based on scientific evidence.
