简要总结

Rapid palatal expansion aims at skeletally correcting the transverse maxillary deficiency by applying forces to separate the mid-palatal suture. In adult patients, the separation of the mid-palatal suture may not be possible due to its increased interdigitation. Miniscrew-assisted rapid maxillary expansion (MARPE) was proposed to transmit the forces directly to the mid-palatal suture through palatal miniscrews in addition to the anchor teeth. However, some non-growing patients may not respond favorably to MARPE. Hence, the use of corticopunctures as an adjunct to MARPE was recently proposed to overcome the increased resistance of the sutures in adult patients.

The study aims to assess and compare the skeletal and dental effects of miniscrew-assisted rapid palatal expansion with and without corticopunctures in non-growing patients.

详细描述

Rapid palatal expansion is a common treatment modality that aims at skeletally correcting the transverse maxillary deficiency by applying forces to separate the mid-palatal suture. In adult patients, the separation of the mid-palatal suture may not be possible due to its increased interdigitation and ossification. Miniscrew-assisted rapid maxillary expansion (MARPE) was proposed to transmit the forces directly to the mid-palatal suture through palatal miniscrews in addition to the anchor teeth. However, some non-growing patients may not respond favorably to MARPE. Hence, the use of corticopunctures as an adjunct to MARPE was recently proposed to overcome the increased resistance of the ossified mid-palatal sutures in adult patients.

The aim of the study is to assess and compare the skeletal and dental effects of miniscrew-assisted rapid palatal expansion with and without corticopunctures in non-growing patients.

A randomized clinical trial will be conducted to address the aim of the study. Patients will be randomly and equally assigned to group 1 (Corticopuncture-facilitated MARPE) or group 2 (Conventional MARPE). Both groups will be treated using Maxillary Skeletal Expander (MSE II, Biomaterials Korea Inc., Seoul, Korea). Ten corticopunctures will be made in group 1 along the mid-palatal suture with the aid of a 3D printed surgical guide. The skeletal and dental changes will be assessed using cone beam computed tomography scans obtained before treatment and after 6 months of expansion stabilization. The results will be compared between the groups and analyzed using the appropriate statistical tests.

结局指标

主要结局

Transverse skeletal changes from baseline to an average of 6 months after the initial activation, measured using cone beam computed tomography (CBCT)

时间窗: At baseline and an average of 6 months after the initial activation

The data from CBCT scans at the different time points will be exported in Digital Imaging and Communications in Medicine (DICOM) format and processed using suitable software. The relevant landmarks will be defined and located by the investigator to measure the transverse skeletal changes in mm from baseline to the end of passive retention of the expansion.

次要结局

  • Dento-alveolar inclination changes from baseline to an average of 6 months after the initial activation, measured using CBCT(At baseline and an average of 6 months after the initial activation)
