Objective:The aim of this study was to evaluate the behavior of the overdenture,the mastication force distribution and the stress distribution in alveolar bone induced by the type of the attachment,through three-dimension finite element analysis. Method:The CT data of mandible and denture from a patient were collected. Then reverse engineer softwares were used to construct a 3D finite element model of the complete two implants-supported overdenture,which include mandible,different type of attachment(bar clip attachment B;ERA E;ball attachment R;magnetic attachment M)and overdenture. By definition the contact relationship of different parts of the model and simulate centric occlusion,to investigate the behavior of the overdenture,the mastication force distribution and the stress distribution in alveolar bone. Result:During centric occlusion,the front of the overdenture with ERA or ball attachments were sagged,buffer space delayed and reduced the vertical load of implants;The overdenture with magnetic or bar attachments have no vertical gap,so the front of the overdentue have no settlement,while the back of the overdenture rotated and sagged,Which increased the load of implants. The peak stress in peri-implant alveolar:the bar attachment was the highest,followed by magnetic attachment,ERA was low and the ball attachment was the lowest;The peak stress in posterior alveolar ridge:the bar attachment was the highest,ball attachment secondly,ERA and magnetic attachments were the lowest. Conclusion:The type of attachment have a significant effect on the behavior of the overdenture,the mastication force distribution and the stress distribution in alveolar bone;The vertical gap of the attachments can delay the vertical load of the implants and reduce the risk of the bone resorption surrounding implants.
