Class I - The Ortho Guide
Class I skeletal patterns usually have a mild convex facial profile. The maxilla and mandible are in harmony to the soft tissue glabella. The lower incisors occlude or lie below the cingulum plateau of the upper incisors (British Standards Institute 1983)

2022年3月1日 · Skeletal malocclusions are typically diagnosed in neonatal infants and often accompany tongue deformities, cleft palate, or other skeletal abnormalities. Class I Malocclusion.

2019年6月30日 · Control of maxillary occlusal plane is the key for the successful treatment of skeletal Class I malocclusion. This could be achieved either by en bloc distalization or mesialization of the maxilla by performing a LeFort I osteotomy and bilateral sagittal split osteotomy or by anterior segmental osteotomy.
Class II malocclusion. Hypodivergent Skeletal Pattern A skeletal pattern in which the skeletal planes are more parallel to each other. Characterized by a low mandibular plane angle, short lower facial height and is often associated with Class II Division 2 malocclusions.

Skeletal Class II: Distal mandibular development in relation to the maxilla. The profile is prognathic (Convex). He subclassified skeletal II into: Class II/1: Narrow maxillary arch with crowding in the canine region; Class II/2: Lingually Inclined maxillary incisors, the laterals may be normal or proclined.
15 Class I malocclusion - Pocket Dentistry
2015年1月1日 · A Class I skeletal pattern shows upper and lower jaws of approximately the same size, with a SNA of 80°, SNB of 78°, and an ANB difference of 2°. The maxillo-mandibular planes angle (MMPA) may be increased or average (27°). If the MMPA is decreased there may an increased overbite and a tendency towards a Class II skeletal pattern.

Dentoskeletal morphology in adults with Class I, Class II Division 1 ...
This study aimed to evaluate dentoskeletal morphology in skeletal Class I and II anomalies associated with Angle Class I, Class II Division 1 (Class II/1), and Class II Division 2 (Class II/2) malocclusions with increased overbite compared with normal occlusion.
skeletal discrepancies between the arches are more commonly associated with Class II or Class III occlusions, but milder transverse discrepancies are often seen in Class I cases. Increased vertical skeletal proportions and anterior open bite can also occur where the anteroposterior incisor relationship is Class I. 2. Soft tissues
