Actual (reported)This study aims to evaluate and compare the inclination of the lower and upper permanent first molars and the transversal width of the lower and upper jaws in individuals of different age groups to evaluate whether the existing anomaly at different ages in individuals with a bilateral posterior crossbite. For this reason, first molar tooth inclination and lower and upper jaw transversal width will be evaluated in adolescent and post-adolescent individuals with a bilateral posterior crossbite.

Actual (reported)Mandibular and maxillary first molar positions
The inclinations of the lower and upper permanent first molars in the frontal plane will be evaluated.
At the beginning of the examination, it will be evaluated as an average of 10 minutes for each patient's lower and upper jaw.
Dimensions of the upper dental arch in the transverse direction
The distances of the right and left permanent canines, first and second premolars, and permanent first molars transversely to each other in the upper jaw of each patient will be evaluated. In addition, dental arch perimeter and dental arch depth will be evaluated.
At the beginning of the examination, it will be evaluated as an average of 15 minutes for each patient's maxilla.
Dimensions of the lower dental arch in the transverse direction
Individuals with bilateral posterior crossbite will be included.
Individuals with no anterior and/or posterior crossbite and transversal malocclusion will be included.
No interventional treatment intervention will be made for individuals. Digital dental models taken for orthodontic recording will be examined.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.

Actual (reported)Precision Orthodontics: A Comparison of Custom vs Traditional Bracket Treatment Efficiency
The distances of the right and left permanent canines, first and second premolars, and permanent first molars transversely to each other in the upper jaw of each patient will be evaluated. In addition, dental arch perimeter and dental arch depth will be evaluated.
At the beginning of the examination, it will be evaluated as an average of 15 minutes for each patient's mandible.
Evaluation of the transverse dimensions of the lower and upper jaws between different age groups
The differences between the periods of different age groups (12-14 years, 14-16 years and 16-18 years) will also be evaluated separately for each group and parameter.
At the beginning of the examination, it will be evaluated as an average of 25 minutes for each patient's mandible.
Evaluation of the transverse dimensions of the lower and upper jaws between the sexes
At the beginning of the examination, it will be evaluated as an average of 25 minutes for each patient's mandible.
