Construction of the Three-dimensional Finite Element Model of the Mandibular and Temporomandibular Joint in Patients with Obstructive Sleep Apnea Hypopnea Syndrome
摘要
Abstract
Objective To construct the three-dimensional finite element model of the mandible and temporomandibular joint (contains the upper airway and surrounding structures) in patients with OSAHS (obstructive sleep apnea hypopnea syndrome) , and provide references for the treatment of OSAHS from the temporomandibular joint. Methods The section images of an OSAHS patient's mandible and temporomandibular joint were acquired by thin- section CT scanning and digital image processing was utilized to construct a three-dimensional finite element model by using mimics, image ware and ansys software. Results The three -dimensional finite element model was constructed which including 949850 elements and 932932 nodes with the mandible and temporomandibular joint. The exact three - dimensional shape of model was well constructed: it also simulated mandibular advancement oral appliance for the treatment of OSAHS to provide a reference for further study of the treatment from the temporomandibular joint. Conclusions The three - dimensional finite element model of the mandible and temporomandibular joint (includes he upper airway and surrounding structures) is more accurate and applicable. It is a basis for further study of OSAHS treatment from the temporomandibular joint.关键词
