Abstract

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.

Highlights

Introduced in the late 1970s, the concept of implants installed immediately after tooth extraction has become increasingly popular in dental clinics over the past few years
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
There are countless benefits intrinsic to the technique of immediate implant installation, such as less bone resorption, preservation of patient aesthetics and reduction of treatment time and costs, many of them helping to reflect on a better prognosis (Hegde, Prasad, Shetty & Shetty, 2013 and Vergara & Caffesse, 2003)

Summary

Introduction

Introduced in the late 1970s, the concept of implants installed immediately after tooth extraction has become increasingly popular in dental clinics over the past few years. This growing success is largely due to the preservation of the patient's aesthetics, reduction of Research, Society and Development, v. The work in question deals with a case report in a qualitative and descriptive way, with the objective of demonstrating the removal of a maxillary sinus implant using the modified Caldwell-Luc Technique, as well as its indications, of a patient attended at the dental school of Araçatuba UNESP/SP - Brazil.
