What is the effect of molar intrusion with temporary anchorage devices on the vertical facial morphology and mandibular rotation in the permanent dentition stage during open bite treatment?
The objective of the study is to assess the effect of molar intrusion with temporary anchorage devices on the vertical facial morphology and mandibular rotation during open bite treatment in the permanent dentition.
Therefore, the goal of the current report is to systematically review the effect of molar intrusion with temporary anchorage devices on the vertical facial morphology and mandibular rotation during open bite treatment in the permanent dentition stage.
In order to evaluate the results of molar intrusion in the treatment of open bite malocclusion, it is necessary to recognize the effect of the posterior teeth intrusion on the mandibular rotation and facial morphology.
The images in the CMU, FERET and MIT-CBCL face databases include variations to imitate real-world conditions, such as slight rotation, different facial expressions, different race, and different illumination directions.
Future well-conducted and clearly reported multicenter randomized controlled trials with a non-treatment control group are needed to provide the best scientific evidence relating to the effect of molar intrusion on the mandibular rotation and facial esthetic during open bite treatment.
Current available evidence suggests that that posterior teeth intrusion in the permanent dentition stage using TADs might cause mandibular counterclockwise rotation and improve facial esthetics.
The intrusion of posterior teeth with temporary anchorage devices was suggested to lead to decreased lower facial height by a counterclockwise rotation of the mandible; this may resemble the orthognathic surgery outcomes for any open bite patients [10].
The large OH 5 cranium from Olduvai, originally assigned as a male [28], is here considered a female, based on the predicted correlates of a developmental model of posterior vertical facial hyperplasia and upward maxillary rotation (Table S1).
Prolonged positive allometric growth of the ramus and corresponding posterior vertical expansion of the upper face in men would determine the degree of anterior facial remodeling and the upward rotation of the nasomaxillary complex.
