Fracture resistance of single-tooth implant-supported

Ver documento

Detalhes bibliográficos
Resumo:The purpose of this study is to identify and compare the fracture behaviour of the ceramic used in a single-tooth implant-supported. This type of prosthesis is mainly used when a single tooth replacement is needed. Two different materials are tested for the abutment (ceramic and titanium), assuming fully connection to the crown. The implant is made of titanium. The numerical simulations used the concept of continuous damage mechanics to predict crack pattern when loading the tooth in the vertical direction. The ceramic abutment grants an increase of 10% in fracture resistance and is able to accommodate a larger extension of damage material of the crown.
