Computed Guided Prolotherapy Versus Conventional Prolotherapy

An auriculotemporal nerve block using Mebacaine 0.5% was administered near the mandible's neck. The patient sat at a 45° angle with their head turned. The posterior entry point was 10 mm from the midtragus and 2 mm below the line, while the anterior entry point was marked 20 mm from the midtragus and 10 mm below the line. A biting block kept the mouth open. 2-3 ml of Ringer lactate was injected with an 18-gauge needle to enlarge the joint space. A second needle allowed the solution to flow freely. After lavaging the joint, 1 ml of I-PRF was injected into the upper joint space. Jaw manipulation was done to address adhesions and improve disc mobility.

Patients underwent arthrocentesis with Ringer lactate, followed by I-PRF injection in the TMJ's superior space using a CT-planned 3D-printed guide. Positioned at a 45° angle, patients were comfortably seated, and disinfection was performed. The patient-specific guide, fitting over maxillary teeth and the face, was employed unilaterally or bilaterally with a biting block for mouth opening maintenance. An 18-gauge needle administered 2-3 ml of Ringer lactate, widening the joint space, followed by a second needle allowing free solution flow (80-90 ml) to flush the superior joint space. Post-arthrocentesis, 1 ml of I-PRF was injected. To enhance joint mobility and free the disc, gentle manipulation of the lower jaw was performed after removing the needles and guide.
