Rapid maxilary expansion in young adults: comparison of tooth-borne and bone-borne appliances, a cohort study.

Abstract

Resumen: Introducción: Las compresiones maxilares son una de las anomalías más frecuentes, independiente del tipo de dentición que se esté estudiando. Su tratamiento se puede realizar con un aparato expansor ya sea dentosoportado o esqueletalmente soportado, dependiendo de las consideraciones de maduración biológica del paciente. Se ha demostrado éxito en el tratamiento en etapas prepuberales, sin embargo, existe evidencia de una sutura abierta aún en etapas post adolescencia. El objetivo de este estudio es comparar, mediante Cone Beam CT, los efectos de un dispositivo de expansión rápida maxilar esqueletamente soportado, en relación a los dentosoportados, en adultos jóvenes con compresión maxilar. Material y método: Se realizó un estudio de tipo observacional retrospectivo, donde se evaluaron nueve pacientes (tres hombres y seis mujeres) con un promedio de edad de 18±5,5 años,que asistieron al Servicio de Ortodoncia de la Universidad de Chile, durante los años 2014-2015. Seis pacientes fueron tratados con aparatos dentalmente soportados (tipo Hyrax) y tres pacientes con apartos esqueletalmente soportados (MARPE). A través de CBCT se

Tomographic dimensions for the installation of rapid maxillary expansion mini-implants in different age groups

“…Mini-implant-assisted for RME, or MARPE, is a means of expanding basal bone without surgical intervention in adolescent patients 18 and young adults, 8 which has been shown to be a treatment modality that is associated with a high success rate in maxillary expansion, skeletal and dental, 19 which is why it is important to know how the dimensions of the maxilla are manifested, in the palatal region, where the mini-implants intended to be used with MARPE are placed.…”

“…6-8 Knowledge of the linear values of the upper jaw is the basis for planning orthodontic treatments that require RME, 9-11 such as mini-implant-assisted rapid palatal expansion (MARPE), which generates an increase significant in the transverse maxillary skeletal dimension, showing a more parallel radiolucency of the palatal suture than traditional methods, causing fewer collateral effects on the posterior teeth, such as the greater angulation of the molars generated by dental support methods. 8 Palate has become an important site for the placement of anchorage devices, due to its bone quantity and quality, 9 especially if RME is desired. 6 The morphology of the craniofacial region is predominantly controlled by genetic factors; however, functional demands can have a significant effect on growth and development.…”

Sutural loading in bone‐ versus dental‐borne rapid palatal expansion: An ex vivo study

“…A retrospective study by Rojas et al compared the success rate of DRPE and BRPE in patients with an average age of 18 ± 5.5 years using CBCT 31 . Successful expansion was observed in all the BRPE patients compared to only half of the DRPE subjects.…”

Non-surgical rapid maxillary expansion with mini-implants in adults: A Narrative Review

“…6 Traditionally RME has been able to be performed in prepubertal stages; however, evidence has recently emerged of opening the maxillary suture in post-adolescent stages. 7 and even more in the adult stage, 8 in which it would be very useful, considering that this approach has been conventionally performed by surgery only. 3 For this reason, it is necessary to synthesize all the current information about this therapeutic procedure in adulthood.The objective of this narrative review is to present the results reported in the scientific literature about RME with skeletal anchorage in adults.…”
