Impact of Maxillomandibular Sagittal Variations on Upper Airway Dimensions: A Retrospective Cross-sectional CBCT Evaluation.

Aim: This study aimed to analyze the upper airway dimensions in adult patients with different anteroposterior (sagittal) skeletal malocclusions (class I, II, and III) using cone beam computed tomography (CBCT) imaging.

Materials And Methods: This retrospective cross-sectional study involved 90 CBCT records from adult subjects who were categorized into three skeletal groups based on their ANB values: Class I ( = 30), class II ( = 30), and class III ( = 30) and were evaluated. The following upper airway measurements were considered: oropharyngeal airway volume, hypopharyngeal airway volume, pharyngeal airway volume, oropharyngeal airway length, hypopharyngeal airway length, pharyngeal airway length, the most constricted site of the pharyngeal airway, and the most constricted cross-sectional area (MIN-CSA) of the pharyngeal airway.

Optimized human dedifferentiated fat cells from the buccal fat pad-derived osteoinductive extracellular vesicles promote osteoblast differentiation.

Background/purpose: Bone reconstruction in the maxillofacial region typically relies on autologous bone grafting, which presents challenges, including donor site complications and graft limitations. Recent advances in tissue engineering have identified highly pure and proliferative dedifferentiated fat cells (DFATs) as promising alternatives. Herein, we explored the capacity for osteoblast differentiation and the osteoinductive characteristics of extracellular vesicles derived from DFATs (DFAT-EVs).
