Etiology and clinical treatment of apical peri-implantitis
Apical peri-implantitis(API)is an inflammato-ry lesion categorized as one of the biological complications of dental implants,with a relatively low clinical occurrence rate(0.26%-3.80%).This condition typically localizes around the periapical region of the implant,while other bone-implant interfaces remain unaffected.In the early stages of API,char-acteristic clinical symptoms are often absent,and detection of potential lesions relies on radiographic imaging.Currently,there is a lack of universally recognized classification systems and clinical treatment consensus for this condition.Treatment options generally involve non-surgical approaches aiming at implant preservation and surgical interventions,including flap elevation with implant apical surgery,guided bone regenera-tion,and/or implant apical resection.Early diagnosis and treat-ment of API during the osseointegration phase holds promise for improving implant survival rates and reducing the risk of implant removal.
