The implant-supported rehabilitation ofposterosuperior sectors may be sometimes conditioned by the pneumatization of the para-nasal sinuses, which decreases the possibility of implant placement when the bone height is < or = 4 mm. (prerequisite for primary stabilization). Sinus lift surgery with simultaneous application of implants is the procedure which provides the best chance of success comp...

i ntroduction: bisphosphonates are  widely used  for  various bone  diseases including osteoporosis and bone tumors. one of the complications associated with these pharmaceutical agents is bisphosphonate-related osteonecrosis of the jaw. this condition may be triggered by placement of dental implants. in turn,  osteonecrosis  of  the  jaw  may  cause  failure  in  osseointegration  of implants....

Various studies already have shown that the occurrence of oral implant failure is higher in the maxilla than in the mandible. To learn whether Ca-P coatings can improve the success rate of oral implants in the maxilla, three different plasma-sprayed, Ca-P-coated, self-tapping Brånemark implants were inserted in the trabecular bone of the maxilla. Before the insertion of the implants, the two fi...
