BACKGROUND: The aim of this study was to present a retrospective review of cases through questionnaires, evaluating the impacts of customized prostheses for patients with temporomandibular joint (TMJ) disease.
METHODS: A retrospective study of TMJ reconstruction with TMJ prosthesis, customized by Engimplan/Materialise Company (Rio Claro, Brazil), evaluated a total of 22 adult patients aged over 30 years (73%), over a period of 2 years, with 31 prostheses implanted with varied diagnoses (bone degeneration, ankylosis, orthognathic sequelae, and trauma) obtained with preoperative imaging tests (computed tomography) and clinical evaluation of the patient.
RESULTS: The pre- and postoperative results were measured by OHIP Table I4, maximum interincisal opening (MIO), eating ability, pain, satisfaction, and prosthesis safety (infection, sensitivity, paranesthesia, and stability of prosthetic components) within 15 days, 3 months, 6 months, and 1 year. Results demonstrate that the installation of customized prostheses, through what was designed in the customized virtual presurgical planning, achieved positive patient outcome 1 year after surgery, impacting significantly on the absence of pain (average VAS 1±1.1/10), with MIO (36±4 mm) and eating ability (VAS 9.3±0.8/10) within normality and stability of prosthetic components (no revisions), significantly improving all OHIP-14 parameters (average from 22±2 preoperatively to 3±0.8 after 1 year, P<0.01) and being able to affirm the creation of state of the art in customized TMJ prostheses.
CONCLUSIONS: Future research is needed to address the long-term safety and performance of this TMJ prosthesis.
