Total condylar prosthesis for alloplastic jaw articulation replacement.

Area of Science:

• Biomaterials Science
• Orthopedic Surgery
• Dental Mechanics

Background:

• Growing interest in mandibular joint endoprostheses.
• Understanding compressive forces during jaw rotation is crucial.
• Focus on developing complete artificial joints from the outset.

Purpose of the Study:

• To describe clinical results of individually-produced Wisil total mandibular joint endoprostheses.
• To evaluate the success of treatment using patient assessments, clinical findings, and biomechanical measurements.
• To present a novel total mandibular joint prosthesis based on accumulated experience.

Main Methods:

• Implantation of 9 custom total endoprostheses in 6 patients.
• Post-operative assessment of jaw function via patient self-reporting.
• Clinical examination, tooth load measurements, and jaw tracing for treatment evaluation.

Main Results:

• Successful clinical outcomes reported by patients regarding jaw function.
• Positive clinical findings and biomechanical data supporting prosthesis efficacy.
• Experience gained informed the design of a new prosthesis with distinct material and condyle shape.

Conclusions:

• Individually-produced Wisil total mandibular joint endoprostheses demonstrate successful clinical application.
• A combination of patient, clinical, and biomechanical assessments is effective for evaluating treatment success.
• Further innovation in mandibular joint prosthesis design is guided by clinical experience.
