无牙颌种植义齿修复咬合接触设计的研究进展

Advances in occlusal contact design of implant-supported dentures in complete edentulous patients

种植义齿咬合接触的设计是无牙颌患者种植修复的重要考量因素之一。适宜的咬合力在保证患者咀嚼能力的同时,避免种植体受到过大负荷,而不良咬合力则会影响种植修复的预后。无牙颌患者种植义齿的正中咬合接触设计应当尽量保证咬合力平行于种植体长轴,减少悬臂梁和不良支点的存在,保持后牙接触的均匀稳定,首选尖牙保护作为种植体保护性咬合。

The design of occlusal contact of implant-supported dentures is one of the important factors to consider for implant restoration in patients with edentulism.Proper occlusal force can ensure the patients'chewing ability and avoid excessive loading on the implants,while improper occlusal force will affect the prognosis of implants.The design of the centric occlusal contact for patients with edentulism should ensure that the occlusal force is parallel to the long axis of the implants,reducing the existence of cantilevers and improper fulcrums,and maintain the even and stable contact of the posterior teeth.The first choice of implant protected occlusion is the canine guide occlusion..
