Palatal Expansion Technique

Brief summary
This study aims to compare two different methods for maxillary expansion in adult patients with transverse maxillary deficiency. Participants will receive either miniscrew-assisted rapid palatal expansion (MARPE-MICRO-4). We want to compare the surgically assisted rapid palatal expansion (SARPE) and the non surgical/conservative method. Clinical (3D scans of the upper jaws) measurements will be used to evaluate skeletal expansion and stability over time. Approximately 90 adult patients will be included and followed for 12 months. The results of this study may help clinicians choose the most appropriate treatment method for adult maxillary expansion.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Skeletal maxillary expansion measured with 3D scans | Baseline to 6 months after completion of maxillary expansion. | Changes in intermolar and intercanine width will be measured on digital dental models. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Buccal tipping of posterior teeth measured on 3D digital models | Baseline to 6 months after completion of maxillary expansion | Buccal tipping of posterior teeth will be assessed using 3D digital dental models by measuring changes in crown inclination of maxillary premolars and molars before treatment and after completion of maxillary expansion. |
