Dentoskeletal Changes In The Transverse Dimension Using Tooth Bone-Borne Vs. Bone-Borne Expansion Appliances

Not Applicable

Completed

• Conditions: Transverse Maxillary Deficiency

• Registration Number: NCT05930054
• Lead Sponsor: TC Erciyes University

Brief Summary

This study aimed to investigate the skeletal, dentoalveolar, and periodontal changes of tooth-bone-borne (TBB) and bone-borne (BB) appliances with identical miniscrew placement using cone-beam computed tomography (CBCT) in the post-pubertal growth spurt stage.

Detailed Description

Eighteen patients were divided into 2 groups: TBB group (n = 9, 16.11 ± 0.59 years of age) and BB group (n = 9, 15.33 ± 1.22 years of age). CBCT scans were obtained before treatment and after 3 months of expansion. Transverse skeletal and dental expansion, alveolar and tooth inclination, and buccal alveolar bone thickness were evaluated in maxillary first premolars and molars. Paired t tests and independent-sample t tests were used to compare the expansion appliances.

Primary Outcome Measures

Name	Time	Method
Nasal Changes	up to 1 year	Nasal Width:Distance between right and left inner lateral limits of nasal cavity, parallel to the base of the nasal cavity, Nasal Floor Width :Width at widest portion of floor of the nose

Secondary Outcome Measures

Name	Time	Method
Maxillary Skeletal Changes	up to 1 year	Maxillary width:Maxillary width tangent to nasal base at tooth level ,palatinal maxillary width:The distance between the inner cortical points of the palatinal bone
Dentoalveolar Changes	up to 1 year	The palatal alveolar angle (PAA) is the angle between the lines created by drawing tangents to the right and left palatal alveolar plates
