Summary

Previous studies confirmed that MARPE (Mini-screw Assisted Rapid Palatal Expansion) technique resulted in transverse skeletal expansion without the undesired dentoalveolar compensations or drawbacks. It also resulted in widening of the nasal cavity and zygomatic bone. ALT-RAMEC (Alternate Rapid Maxillary Expansion and Constriction) in literature proved to be advantageous over conventional RME in producing subluxation and sutural displacement to facilitate maxillary protraction in skeletal class III growing patients.The current study investigates the efficacy of a combination of MARPE/ ALT-RAMEC techniques to expand the maxilla in adult cases of transverse maxillary deficiency. It compares the proportion of success cases in patients who are treated with MARPE/ ALT-RAMEC to those treated using MARPE (conventional). It also describes the circum-maxillary sutural displacement in patients treated with both techniques, it hypothesizes that it will result in transverse skeletal expansion as well as sutural subluxation and displacement in young adult ages, which may be a sign of hope in the treatment of antero-posterior deficiency in adults without resorting to surgery. It also will describe the dento-skeletal changes (the amount of dental tipping) and the respiratory changes that occurred after applying the two different expansion techniques. It will also compare clinically, the changes occur gingivally (Gingival recession and Pocket depths) between pre-treatment and post-expansion periods.

Conditions

  • Maxillary Dysostosis (Disorder)

Interventions

PROCEDURE

Mini-screw Assissted Rapid Palatal Expansion

Mini-screw assissted RPE will be the main intervention in the two comparative groups. In the control (group A) will be used with its conventional activation protocol. While in experimental (group B) will be used with ALT-RAMEC protocol.
