Virtual planning for total temporomandibular joint replacement
Official title: Three-dimensional Virtual Planning of Total Temporomandibular Joint Replacement Using Standardized Prosthesis.
Run by Lund University Hospital · NCT07373184 · Data updated 2026-11-12
This project sees if virtual planning using standard (non‑custom) TMJ prostheses can plan jaw and implant positioning for patients who already had total TMJ replacement.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for inclusion are patients with severe TMJ pathology who previously underwent total TMJ replacement at the Department of Oral and Maxillofacial Surgery, Skåne University Hospital (Lund) between 2010 and 2025 and who have not had additional TMJ surgery afterwards.
✕Probably not a fit
Patients who had additional TMJ surgery after the replacement or whose anatomy requires bespoke, patient‑specific implants are unlikely to benefit from virtual planning using standardized prostheses.

What this trial studies
This retrospective project uses imaging and surgical records from patients treated with total TMJ replacement at Lund University Hospital between 2010 and 2025. Investigators generate virtual models and run treatment simulations using standardized (off‑the‑shelf) TMJ prosthesis templates to plan jaw movements, prosthesis positioning, and fixation. Measured outcomes include maximal bone–prosthesis interface area, number of possible fixation screws, the ability to centre the mandibular component in the fossa, and the surgical movements required to correct severe malocclusion. The aim is to determine surgical feasibility of virtual planning with standardized prostheses and whether some benefits of custom implants can be delivered at lower cost.
Why it matters
Potential benefit: If successful, this approach could bring the advantages of virtual surgical planning to more patients at lower cost by enabling reliable planning with standardized TMJ prostheses.
How similar studies have gone: Patient‑specific TMJ prostheses and virtual surgical planning have seen clinical use and success, but applying the same virtual planning methods systematically to standardized off‑the‑shelf TMJ prostheses is less well tested.
