Dentoskeletal Changes In The Transverse Dimension Using Tooth Bone-Borne Vs. Bone-Borne Expansion Appliances
- Conditions
- Transverse Maxillary Deficiency
- Interventions
- Device: skeletal anchorage and rapid palatal expansion
- 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.

Group Intervention Description bone-borne (BB) group skeletal anchorage and rapid palatal expansion The BB appliance was composed of a central expansion jackscrew, 4 tubes as described in TBB group, and less acrylic used around it to adjust its position. In order to carry it to the mouth after preparation on the cast model, essix was used, which also included the patient's teeth tooth-bone-borne (TBB) group skeletal anchorage and rapid palatal expansion The TBB appliance was composed of a central expansion jackscrew (Dentarum), 4 tubes, 2 bands on the upper first molars to facilitate placement of the appliance, and 1.5-mm diameter stainless steel arms extending to the premolar teeth. Soldered stainless steel tubes (internal diameter: 2.0 mm; external diameter: 3.0 mm; length: 2.0 mm) served as guides for miniscrew placement. The size of the screws (PSM) was chosen as 1.8 mm in diameter and 11 mm in length, considering the 2 mm height of the tubes, 1 to 2 mm gap between the appliance and the palate surface, 1 to 2 mm gingiva thickness, and 5 to 6 mm length required for the bicortical placement of the screw in the bone.
- 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
