Augmented reality-guided endodontics: Minimally invasive access through the prosthesis using AReneto® system - A case...

Area of Science:

• Endodontics
• Dental Technology
• Augmented Reality in Medicine

Background:

• Vital tooth preparation for dental prostheses can lead to apical periodontitis.
• Root canal treatment is often necessary but complicated by the challenge of prosthesis removal.
• Patient cost concerns can further complicate treatment decisions regarding prosthesis removal.

Purpose of the Study:

• To explore the use of the AReneto® system for minimally invasive endodontic access through existing prostheses.
• To evaluate the effectiveness of an augmented reality (AR)-guided approach in endodontic treatment.
• To demonstrate a method for avoiding prosthesis removal during root canal treatment.

Main Methods:

• A case series involving two patients with porcelain-fused-to-metal (PFM) bridge prosthesis and periapical pathology.
• Preoperative virtual planning of the access cavity using the AReneto® system.
• Intraoperative guidance via AR glasses projecting the planned access into the clinician's field of view.

Main Results:

• The AReneto® system facilitated accurate endodontic access through the existing prosthesis.
• Root canals were successfully cleaned, shaped, and obturated.
• Follow-up confirmed resolution of symptoms and healing of periapical pathology.

Conclusions:

• The AReneto® system enables precise, minimally invasive endodontic access, eliminating the need for prosthesis removal.
• This approach reduces treatment complexity and enhances clinical efficiency.
• Successful outcomes were achieved, validating the AReneto® system's effectiveness.
