This study evaluated the von Mises stress (MPa) and equivalent strain occurring around monolithic yttria-zirconia (Zir) implant using three clinically simulated finite element analysis (FEA) models for a missing maxillary central incisor. Two unidentified patients’ cone-beam computed tomography (CBCT) datasets with and without right maxillary central incisor were used to create the FEA models. Three different FEA models were made with bone structures that represent a healed socket (HS), reduced bone width edentulous site (RB), and immediate extraction socket with graft (EG). A one-piece abutment-implant fixture mimicking Straumann Standard Plus tissue level RN 4.1 X 11.8mm, for titanium alloy (Ti) …

Osteopetrosis, or marble bone disease, is a disturbance of skeletal development in which the rate of bone resorption fails to keep pace with the rate of bone formation. Bone matrix accumulates excessively throughout the skeletal system, causing damage to neighboring tissues--particularly the dental, hematopoietic and nervous tissues. The line of investigation on osteopetrosis which has led to the current point of view that the thyroid gland represents the primary side of the disturbance was initiated soon after an experimental animal became available.
