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.
