Research/Original Article (دارای رتبه معتبر)

Maxillary transverse deficiencies pose significant challenges in orthodontics, necessitating effective treatment methods. Traditional approaches like rapid maxillary expansion (RME) have demonstrated limitations, especially in skeletally mature patients. Skeletal anchorage-based expansion methods, such as miniscrew-assisted rapid maxillary expansion (MARME), have emerged as viable alternatives, offering advantages in terms of reduced dental side effects and improved stability.

Report of a Case: 

A 14-year-old female presented with a severely constricted maxillary arch and intricate occlusal issues. This case report details the utilization of MARME as a treatment modality. Miniscrews were strategically placed by an orthodontist specialist, and the expansion process was carefully monitored. Post-treatment outcomes revealed a significant increase in midpalatal suture opening width, showcasing the effectiveness of MARME. Cone beam computed tomography images demonstrated a notable expansion of the transverse dimension, leading to improved occlusal relationships.


Skeletal anchorage-based expansion, particularly MARME, stands out as a preferred method for addressing maxillary constriction in adolescents. This case serves as an illustration of the feasibility and distinctive advantages of Temporary Anchorage Devices (TADs) in the context of maxillary expansion for skeletally mature patients.
