Maxillary sinus implant removal: modified Caldwell-Luc technique
Keywords:Mouth rehabilitation; Surgery, Oral; Maxillary sinus; Maxillary sinusitis.
The installation of immediate implants after tooth extractions is becoming a common practice in the dental clinic. During this surgical procedure, complications such as the displacement of dental implants into the maxillary sinus may occur due to the close relationship between the floor of the maxillary sinus and the upper teeth. In these cases, treatment consists of removing the implant that has been displaced in order to prevent future complications such as maxillary sinusitis and oroantral fistula. The present study aims to present a clinical case in which the removal of the maxillary sinus implant was performed using the modified Caldwell-Luc Technique. The patient sought a private clinic for extraction of the left upper second molar and oral rehabilitation with implants. Even with little bone height between the floor of the maxillary sinus and the crest of the alveolar ridge, the professional opted for immediate implant installation after extraction, but when returning after 90 days, the implant had moved into the sinus. The implant was removed using the modified Caldwell-Luc technique, which consists of making a bone window in the lateral wall of the maxillary sinus, removing the fragment, replacing the bone window, and suturing the previously folded flap. Therefore, it can be concluded that the Caldwell-Luc technique benefits the closure of the bone defect, avoids fistulas and the area of fibrosis in the membrane, being an effective and viable alternative for removing implants in the maxillary sinus region.
