In-house handcrafted 3D tools for arthroscopic discopexy of the temporomandibular joint. A technical note.

BACKGROUND

Arthroscopic discopexy is a minimally invasive procedure for treating internal derangement of the temporomandibular joint (TMJ). However, a long learning curve limits its widespread adoption, as it is a technique that requires high skill, specialized instruments, and a high cost, as well as difficult access.

OBJECTIVE

This study aims to propose a design for a new instrument, fabricate it, and evaluate a set of low-cost 3D-printed instruments to facilitate arthroscopic TMJ discopexy.

METHODS

The instruments were designed using computer-aided design (CAD) software and fabricated with Kirschner nail, orthodontic pliers, and methacrylate via 3D printing. Also, a short case series is mentioned as a proof of concept.

RESULTS AND

CONCLUSIONS

The 3D-printed instruments were successfully used to perform the discopexy procedure in ten cases, demonstrating comparable performance to conventional instruments at a fraction of the cost without any complications related to instruments or surgical technique.
