Diagnosis and prosthodontic management of a complicated posterior implant in the maxillary sinus region by radiography and sinoscopy

ABSTRACT

A case was presented in which there was a screw-vent implant inserted in the maxillary posterior edentulous area. The implant was presented with both clinical and radioographic manifestations suggestive of encroachement on the maxillary sinus and the decision was directed towards removal of the implant. An endoscopic examination of the maxillary sinus revealed that the sinus lining was completely continuous and intact. A period of three months was allowed for bone healing together with the proper medication of the patient. A suprastructure was constructed with consideration to the suitable design which offered a proper load distribution and decreased effect of the occlusal forces. A clinical-radiographic follow up of the case has denoted a successful implant without notable clinical mobility or peri-implant inflammation as well as healthy bone surrounding the implant
