I am a periodontist and recently had a case referred for installation of a dental implant in #3 area [maxillary right first molar; 16]. Â The patient had #3 extracted 2 weeks prior and there is a root tip — probably from the palatal root — in the maxillary sinus. Â This is clearly visible in the CBVT scan. There is also an apparent oral antral fistula between the maxillary sinus and the oral cavity. Â I prescribed Biaxin [clarithromycin]. What is the recommended course of treatment to manage the root tip and graft the area for a future implant? How do you recommend I proceed? Â
