Clinical Trial 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.

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.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 18
• Est. completion date: July 12, 2022
• Est. primary completion date: May 10, 2021
• Accepts healthy volunteers: No
• Gender: All
• Age group: 14 Years to 17 Years

Eligibility

Inclusion Criteria:

• With a unilateral or bilateral morphological lateral crossbite
• Whose first molars and premolars had completely erupted at pretreatment
• With maxillary constriction of more than 4 mm and less than 10 mm
• Who were going through the post-pubertal growth spurt stage based on hand-wrist radiographs

Related Conditions & MeSH terms

• Transverse Maxillary Deficiency

Intervention

Device:
• skeletal anchorage and rapid palatal expansion
Eighteen patients were randomly divided into 2 groups through a free randomization program (Random Allocation Software 2.0). Baseline demographic characteristics were matched in both groups. All appliances were fabricated by the same technician in the orthodontic lab. All individuals were treated by a single practitioner.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Nasal Changes	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	up to 1 year
Secondary	Maxillary Skeletal Changes	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	up to 1 year
Secondary	Dentoalveolar Changes	The palatal alveolar angle (PAA) is the angle between the lines created by drawing tangents to the right and left palatal alveolar plates	up to 1 year
