What this Trial Is About
Aim of the study: assess the effect of printed framework pure bone-born rapid maxillary expanders on MPS. Materials and Methods: The intra-oral scan and CBCT will be sent to the lab for MARPE fabrication, four mini-screws size 10mm in length, and 1.7 mm in diameter will be placed, after that, the device will be retained to the mini-screws by retaining screw. The activation of MARPE will be 1 turn (0.25 mm per turn) per day. After 3 months, a CBCT image will be taken to assess the MPS. Outcomes: CBCT analysis: For the first premolar and the first molar: points will be made at the most anterior section where the crown and palatal root can be seen at their greatest length. For the second premolar: in the most anterior section showing maximum length of its root. Measuring the distance between the external right and left maxilla edges in the axial view before expansion and after 3 months from the first activation. Tooth inclination will be measured using the coronal section at a point on the most anterior section, where the crown and the mesiobuccal root can be seen at their greatest length. Buccal alveolar bone thickness measurements were made from the outermost point of the bones to the mesiobuccal root at the level of the furcation point, and fenestration were also evaluated.
