Circumferential Occlusal Access Procedure (COAP): Novel Minimally Invasive Surgical Approach for Treatment of Peri-Implantitis- A Case Series.

Treatment of peri-implantitis is typically most successful when a full-thickness surgical flap is elevated to access the contaminated implant surface and the bone loss that has occurred. This approach, however, can be problematic. Primary flap approximation can be challenging after a regenerative procedure, especially with a shallow vestibule, thin mucosa, or minimal zone of keratinized tissue. Incomplete wound closure and soft-tissue dehiscence can lead to membrane and graft exposure. In medicine, minimally invasive techniques have been developed and are being used in an increasing variety of procedures. This article will present the circumferential occlusal access procedure (COAP), a minimally invasive, flapless surgical technique designed to access and detoxify a contaminated implant surface and facilitate bone repair or regeneration while reducing the potential for membrane exposure and recession.
