Aim. The aim of this case series is to introduce a new surgical template designed for static endodontic microsurgery using Piezosurgery®. The template, created with computer-aided design/computer-aided manufacturing (CAD-CAM) technologies, aims to enhance the precision of root-end resections by providing individualized guidance for the surgical procedure. This approach seeks to reduce invasiveness, minimize bone loss, and improve surgical outcomes in cases of persistent apical periodontitis or other post-treatment endodontic complications.
Summary. Conventional endodontic treatments can fail in 14-16% of cases due to persistent infections within the root canal system or extraradicular factors. In such cases, endodontic microsurgery, especially when guided by advanced technologies, offers a high success rate of up to 89%. Recent innovations in piezoelectric devices and CAD-CAM-based surgical templates enable more precise, less invasive procedures. The new surgical template presented in this study allows for accurate root-end resections, ensuring optimal root sealing while minimizing damage to surrounding tissues. The template’s design aims to improve accuracy and reduce the risk of surgical errors compared to freehand procedures, promoting better healing and fewer complications.
Key Learning Point
Persistent apical periodontitis after root canal treatment can often be resolved with microsurgical techniques.
The integration of CAD-CAM technology with Piezosurgery® enhances surgical precision, reducing bone loss and tissue trauma.
Surgical templates designed for static endodontic microsurgery provide individualized, accurate guidance, leading to improved surgical outcomes.
The use of piezoelectric devices offers precise cutting with minimal damage to soft tissues, crucial for surgeries near sensitive structures.
-Advances in guided endodontic surgery are improving success rates and minimizing post-operative complications.
