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

TC Erciyes University18 enrolled

Overview

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.

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.

Conditions

Transverse Maxillary Deficiency

Interventions

skeletal anchorage and rapid palatal expansionDEVICE

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.

Outcomes

Primary Outcomes

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

Time frame: up to 1 year

Secondary Outcomes

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

Time frame: up to 1 year

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

Time frame: up to 1 year
