Anatomical Considerations on the Alveolar Antral Artery as Related to the Sinus Augmentation Surgical Procedure
Bibliographic record
Abstract
BACKGROUND: The alveolar antral artery (AAA) is a vascular structure that often passes through the area of lateral window opening during sinus augmentation and can reach dimensions that, if the vessel is severed, can represent a serious complication of the surgical procedure. PURPOSE: With this narrative review, we aimed at summarizing the results obtained from all the studies that analyzed the variability in anatomical position and dimension of the AAA in order to give the clinician a reference when planning for a sinus augmentation surgery. MATERIALS AND METHODS: A search of available literature was conducted using electronic databases (PubMed and Medline) and manual searching. RESULTS: Detection rate of AAA on cone beam computerized tomography (CBCT) is variable and may depend upon the experience of the clinician. The course of the vessel is most frequently intraosseous, and its diameter, despite being smaller than 1 mm in most of the cases, can have a high incidence of diameters between 1 mm and 2 mm. Mean distances of the AAA from alveolar crest and sinus floor range from 11.25 mm to 26.90 mm and 5.80 mm to 10.40 mm. CONCLUSIONS: Anatomical variants of the AAA that may increase the risk of severe intraoperatory bleeding are frequent and must be detected by the clinician implementing the use of the CBCT.

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; both teacher heads agree on what is shown here.
