stress distribution - Opis:
- A new type of dental implant was designed as multi-component mainly including inset and abutment between which a gap was introduced to guide the force to transmit from the cancellous bone to cortical bone, with the intention to lower the stress peak at cortical bone. By the way of finite element analysis (FEA) associated with advanced computer tomography (CT) and 3D model reconstruction technology to construct precise mandible model, biomechanical aspects of implant were investigated. Compared with traditional implant that created stress dominantly at cortical bone, stress peak at the implant/bone interface in the cervical cortex decreased sharply (about 51%) for new type of implant. Furthermore, varying implant shape and gap dimensions to optimize the design of this new implant was performed. Optimization results revealed that: 1) screwed cylindrical implant is superior to tapered, stepped and smooth cylindrical implant in effectively decreasing the stress peak of bone; 2) deepening and widening gap would contribute to the decline of stress peak, but at the cost of break and destruction of the inset; 3) suitable gap size with the depth of 7mm and width of 0.3mm would be applicable. This work may provide reference forclinical application of dental implant.
