Biomechanical Study About Different Designs Of Implant -supported Mandibular First Molar With Crown

The mandibular first molar plays an important role and endures much more occlusal force in chewing. To restore the missing tooth, implant-supported prosthesis has been widely used and the longevity of the implants has been mainly influenced by the peripheral excessive stress concentration in clinic. Accordingly, the appropriate design of implant-supported prosthesis to balance the stress is an essential problem in dental biomechanical study.As an effective method, Finite Element Analysis has been applied for mechanical study of implant-supported prosthesis, mandible and maxilla, temporomandibular joint and prosthesis. In this study, three-dimensional models of the mandibular first molar of different diameter single implant-supported and double implant-supported with various spatial arrangement were established via CT scan technology, UG and Patran programs. Meanwhile, the peripheral von Mises stresses were observed to explore the biomechanical advantages and theory proof of different implant-supported designs for the dental clinic.
