Alveolar ridge augmentation with the perforated and nonperforated bone grafts
(Journal Of Periodontal And Implant Science, 2014-02-01) [Artigo]
Purpose: Autogenous bones are frequently used because of their lack of antigenicity, but good osteoconductive and osteoinductive properties. This study evaluated the biological behavior of perforated and nonperforated ...
Non-linear 3D finite element analysis of full-arch implant-supported fixed dentures
(Materials Science & Engineering C-materials For Biological Applications, 2014-05-01) [Artigo]
Despite the necessity for faster clinical protocols for immediate loading of implant-supported dentures, there is a lack of biomechanical studies to confirm the rigid splinting effectiveness. We compared the stress in ...
