Abstract (English): Maxillary transverse deficiency (MTD) occurs when the maxilla is narrow in relation to the mandible, leading to malocclusion. Patients with MTD frequently present unilateral or bilateral posterior crossbite, anterior crowding, and prominent buccal corridors when smiling. Over the years, several methods have been developed to address this condition, including Mini-Implant-Assisted Rapid Palatal Expansion (MARPE), which emerged as an alternative to surgical intervention and has undergone modifications and improvements. MARPE utilizes 2 to 4 mini-implants placed in the palate to provide skeletal anchorage, thereby promoting a more parallel opening of the midpalatal suture (MPS) and inducing changes in both hard and soft tissues. Outcomes vary depending on biological, clinical, behavioral, and technical factors. The aim of this article is to conduct a narrative review using digital databases to explore the biomechanical principles of MARPE, its effects in children, adolescents, and adults, and to assess its effectiveness compared to Rapid Palatal Expansion (RPE) and Surgically Assisted Rapid Palatal Expansion (SARPE). It is concluded that MARPE is an effective tool for addressing maxillary transverse deficiency (MTD), with its success depending on several factors such as appliance design and the patient's skeletal maturity. MARPE achieves more stable expansion and presents fewer side effects compared to rapid palatal expansion (RPE). In contrast to (SARPE), it offers a less invasive approach for young adults, although its efficiency tends to decline with increasing age. Future studies could focus on the application of artificial intelligence to enhance MARPE treatment planning. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): La deficiencia transversal maxilar (DTM) se presenta cuando el maxilar es estrecho en relación con la mandíbula, causando maloclusión. Pacientes con DTM presentan con frecuencia mordida cruzada posterior unilateral o bilateral, apiñamiento anterior y grandes corredores bucales al sonreír. A lo largo de los años se han desarrollado varios métodos para tratar esta condición como la Expansión Palatina Rápida Asistida por mini-implantes (MARPE), que surgió como alternativa a la intervención quirúrgica y, que con el tiempo sufrió variaciones y mejoras. Utiliza de 2 a 4 mini-implantes en el paladar, generando un anclaje esquelético; de esta forma provoca una apertura más paralela de la sutura palatina media (SPM), induciendo cambios en los tejidos óseos y blandos. Los resultados varían según factores biológicos, clínicos, conductuales y técnicos. El objetivo de este artículo es realizar una revisión narrativa en bases de datos digitales sobre los fundamentos biomecánicos de MARPE, sus efectos en niños, adolescentes y adultos, y describir su efectividad comparado con Expansión Maxilar Rápida (RPE) y Expansión Palatina Rápida Asistida Quirúrgicamente (SARPE). Se concluye que MARPE es una herramienta efectiva para abordar la DTM, dependiendo su éxito de varios factores como la planificación de la aparatología y la maduración ósea del paciente. MARPE logra una expansión más estable y presenta menos efectos secundarios que RPE. Frente a SARPE, ofrece un abordaje menos invasivo en adultos jóvenes, pero su eficiencia disminuye con la edad avanzada. Futuros estudios podrían centrarse en la aplicación de inteligencia artificial para perfeccionar la planificación del tratamiento con MARPE. [ABSTRACT FROM AUTHOR]
