Abstract

fetched live from OpenAlex

Temporomandibular disorder (TMD) is a multi-etiologic disability, accompanied by a wide range of symptoms, requiring a variety of therapies, with TMJ reconstruction considered the most severe. TMJ surgery is associated with many morbidities and limitations, especially in the elderly. Previous studies have determined the shape and dimensions of the Condylus mandibulae in children and adults, but a range of measurements in the elderly population has yet to be created. This study aims to establish a range of measurements and the morphology of the Condylus mandibulae in an older population using micro CT. 14 cadaveric Condylus mandibulaes (8 male, 6 female; average age, 838.6) were scanned with microCT and measured using Amira 4.1.1 modeling software. The anteroposterior length (LAP), mediolateral width (WML) and height (H) of each Condylus mandibulae was measured from 5 equidistant slices in the coronal, sagittal and axial planes. Additionally, each Condylus mandibulae was measured at its greatest anteroposterior length, mediolateral width and height using digital callipers on the cadaveric specimen. This study is the first to accurately describe the morphology of the Condylus mandibulae in an elderly population. The length and width measurements of digital calliper (10.51 0.87; 18.33 2.35) and corresponding micro-CT (11.46 1.60; 17.62 2.05) both showed high consistency and reliability. Our findings lay the foundation for the creation of an off-the-shelf Condylus mandibulae prosthesis or anatomically shaped Condylus mandibulae scaffold for elderly patients.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
