Abstract:
The implant rehabilitation of maxillary posterior defects involves a number of possibilities ranging from short implants, sinus lift in one or two phases, atraumatic lift with or without filling, pterygoid or zygomatic.
Complications of dental implants occur despite of good planning of surgery and if it happens, you have to know how to solve and is informed of how the specific case of migration of the maxillary sinus implant resolved to immediately resolve the or refer situation and also how to rehabilitate the space. Rehabilitation of a subsequent partial maxillary defect with extraction implant in 13, 15 and 16, with wide implants and atraumatic sinus lift occurs because our disposal 6 mm in height. With sufficient primary stability of 16 as 35Nw the healing abutment is placed, but the tightening by the 15d by insufficient initial setting thereof, the sinus implant migration occurs, immediately resolved with the opening thereof, expanding the alveolar defect and extraction, placing a pterygoid implant. It is concluded that implantology near sinus involves risks that the patient should know and professional knowledge to solve them, that pterygoids implants are adequate to extreme cases of posterior edentulous maxillary alternative and not to rely on the initial primary stability as the bony apposition and changes in bone resorption are continuous immediately after implant placement.
