Implant‐related orofacial pain managed with implant apicoectomy: A case report

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background In recent years, the use of implants has emerged as a widely accepted method for the replacement of missing teeth. Although rare, chronic pain associated with implant placement has been reported in the literature. Conversely, apicoectomy, the removal of the apical portion has been integrated into the implantology field in cases with
