Custom-made Total Joint Replacement for the Management of Recurrent Bilateral Temporomandibular Joint Ankylosis - A Retrospective Study.
Article in Annals of maxillofacial surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Recurrent bilateral temporomandibular joint (TMJ) ankylosis poses a significant challenge due to limited treatment options and extensive functional impairment. Alloplastic total joint replacement (TJR) represents a potential solution, particularly custom-made devices that allow for precise anatomical reconstruction. However, data on the efficacy of custom-made TJR in this specific population remains limited. This study aimed to evaluate the functional outcomes of custom-made alloplastic TJR in managing recurrent bilateral TMJ ankylosis. Specific outcomes assessed include maximal incisal opening (MIO), postsurgical malocclusion, heterotopic bone formation and dietary restriction patient satisfaction. Materials and Methods: This study was a retrospective study on six patients who underwent custom-made alloplastic TJR for recurrent bilateral TMJ ankylosis at a single institution. Preoperative and postoperative MIO and dietary restrictions were evaluated. Radiographic assessments, complications, patient satisfaction and quality of life after surgery were documented. Results: Custom-made TJR resulted in a significant increase in mean MIO from 5.5 mm (standard deviation [SD]: 5.54 mm) preoperatively to 35.17 mm (SD: 2.99 mm) at 1-year follow-up. All patients demonstrated improvement in dietary restrictions. The radiographic assessment showed stable prostheses. No major complications were observed, and all patients reported satisfaction with the surgical outcome. Discussion: This study suggests that custom-made alloplastic TJR is a viable treatment option for patients with recurrent bilateral TMJ ankylosis, leading to substantial improvements in mouth opening, pain reduction and overall function. Larger, prospective, multi-centre studies are needed to confirm these findings and further evaluate the long-term outcomes.
