Dental Implants inside the Maxillary Sinus - Three Case Reports and Proposal of Management

Zagalo, L, Silva Marques, Jm, Zagalo, C

Abstract :

The placement of dental implants is a common practise in dentistry. From this procedure, complications may arise including the intrusion of the implant into the maxillary sinus, which occasionally occurs. The lining epithelium of the maxillary sinus propels its entire content towards the drainage hole. This, by the occlusion of the hole by foreign bodies, causes the frequent development of sinusitis, thus placing formal indication for their surgical removal. A computerized tomography scan of the paranasal sinuses (CT PNS) should be part of the preoperative evaluation to identify the exact location of the implant. The authors propose, illustrating three examples, the performance of Caldwell-Luc technique in situations in which the implant is submucous and performing endoscopic endonasal surgery in other situations. The latter technique allows for less sequelae and does not hinder the eventual achievement of sinus lifting afterwards.
