Occlusal Relations in Patients With Scaphocephaly
Bibliographic record
Abstract
Scaphocephaly results from a premature fusion of the sagittal suture. Usually, cranial vault corrective surgery is performed during the first year of life. There is currently no scientific data regarding occlusion of scaphocephalic patients, or the potential effect of craniovault surgery on the occlusion. The aims were to describe occlusion in scaphocephalic patients and compare with a general pediatric population, and to compare the difference in occlusion of surgically versus unoperated treated scaphocephalic subgroup. A total of 91 scaphocephalic patients (71 boys aged between 2 and 11 y) seen at the Craniofacial Clinic of CHU Ste-Justine's formed the experimental group. All patients received an orthodontic assessment. Among them, 44 underwent craniovault surgery, whereas 47 remained unoperated. Thirty-eight (33 boys; 17 operated) had lateral cephalometric radiographies, some of them also had cephalometric growth follow-ups. Clinical values for dental classification and overjet indicate an increased prevalence of class II malocclusions in scaphocephalic patients. However, interestingly enough, cephalometric values indicative of skeletal class II malocclusions (ie, N-A perp HP, N-B perp HP, N-Pog perp HP, Wits, N-A-Pog) remained within normal limits. Some cephalometric values present statistically significant differences between operated and unoperated patients (ANS-PNS t2, P = 0.025; /1-FH t2, P = 0.028), but these are individual variations not related to scaphocephaly. Maxillary width of scaphocephalic children remains within normal limits. Scaphocephalic patients clinically presented more class II malocclusions compared with normal children. Radiographic values remain, however, within normal limits for both anteroposterior and transverse dimensions. Corrective craniovault surgery did not affect occlusion in these patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
