Summary
Buccal cortical bone inclination in the maxilla differs among vertical facial types. This finding is crucial for optimizing miniscrew placement in orthodontics.
Area of Science:
- Orthodontics
- Dental Anatomy
- Maxillofacial Surgery
Background:
- Maxillary alveolar bone morphology varies with facial type.
- Understanding buccal cortical bone inclination is vital for orthodontic treatment planning.
Purpose of the Study:
- To investigate variations in maxillary buccal cortical bone inclination based on facial height.
- To determine if facial patterns (hypodivergent, normodivergent, hyperdivergent) influence bone angulation.
Main Methods:
- Cone-beam computed tomography (CBCT) scans of 135 adult patients were analyzed.
- Cortical bone inclination was measured relative to the occlusal plane in the maxillary buccal region.
- Measurements were taken at specific interdental sites from canine to second molar.
Main Results:
- Significant differences in cortical bone inclination were observed among vertical facial types (P < .05).
- Variations were noted particularly between the canine-first premolar and second premolar-first molar regions.
- These differences are relevant for miniscrew insertion sites.
Conclusions:
- Vertical facial patterns significantly influence maxillary buccal cortical bone inclination.
- Miniscrew insertion angles in the maxillary buccal region should be adjusted considering the patient's vertical facial pattern.
