An apicoectomy is the surgical removal of the tooth's root tip and surrounding infected tissue when conventional root canal therapy fails. It is an advanced endodontic surgical method designed to save a tooth from extraction by sealing the root from the reverse end.
Treatment Process:
Radiological Evaluation: The size of the periapical lesion and its relation to the surrounding bone are analyzed using high-resolution X-rays.
Microsurgical Access: A small flap is made in the gum to gain direct access to the infected root tip and the surrounding pathological tissues.
Root-End Resection: The apex of the root, which acts as the source of infection, is precisely trimmed and removed.
Retrograde Filling: The tip of the root canal is sealed with specialized biocompatible materials (like MTA) to prevent future bacterial leakage.
Tissue Healing: The site is sutured; over time, the surgical void fills with natural bone, enhancing the tooth's long-term stability.
Benefits and Advantages:
Preventing Tooth Loss: Saves teeth destined for extraction, preserving the natural dental arch and function.
Resolving Chronic Pain: Permanently eliminates persistent throbbing or pain that remains after a standard root canal.
Preserving Restorations: Allows for the treatment of teeth with expensive crowns or bridges without needing to remove the restoration.
Stopping Cyst Development: Prevents root-end infections from evolving into cysts or causing extensive jawbone erosion.
