Various surgical techniques have been proposed to prevent recurrent temporomandibular joint (TMJ) dislocations, with inconsistent results regarding recurrence and preservation of mandibular mobility. We report the innovative use of a custom-made porous bioceramic medical device for the treatment of recurrent bilateral TMJ dislocations. The implants were computer-designed from the patient's preoperative CT scan and manufactured by the Cerhum company. Implantation and fixation were performed through preauricular approaches. At one-year follow-up, no recurrence or surgical complications were observed. Mandibular mobility was within normal limits, and the aesthetic outcome was satisfactory. This is the first reported use of porous bioceramic in the management of recurrent TMJ dislocations. The technique combines the osseointegrative properties of the material with the precision of a patient-specific design. However, the intrinsic fragility of bioceramic requires limiting implant thickness. Additional cases and longer follow-up are mandatory to confirm the efficacy and safety of this novel technique.
