Following Surgically Assisted Rapid Palatal Expansion, Do Tooth-Borne or Bone-Borne Appliances Provide More Skeletal Expansion and Dental Expansion?

Abstract

According to the literature, to achieve more effective skeletal expansion and minimize dental expansion after SARPE, a BB appliance should be favored.

Is There a Significant Difference in Relapse and Complication Rate of Surgically Assisted Rapid Palatal Expansion Using Tooth-Borne, Bone-Borne, and Orthodontic Mini-Implant–Borne Appliances?

“…4,30 In contrast, a significant difference in skeletal expansion has been detected in favor of BB appliances rather than TB appliances in a previous study. 34 A subgroup analysis of premolar and molar expansion in that study showed that BB appliances were more effective in achieving skeletal expansion than TB appliances at the premolar and molar levels. However, at the dental level, no significant difference was seen between BB and TB appliances in the amount of expansion at the premolar and molar levels in our study.…”

Stability and surgical complications of tooth-borne and bone-borne appliances in surgical assisted rapid maxillary expansion: a systematic review

“…Several studies have evaluated the stability, technique, expansion protocols and complications of these appliances, 2,21,49-51,57-59 and a recently published systematic review and meta-analysis has investigated which appliance provides more skeletal and dental expansion. 66 However, there is still no consensus on which appliance has the best outcomes in terms of less dental and skeletal relapse and fewer complications in the postoperative period. 59 A comprehensive search strategy 67 was used in this systematic review, prioritising sensitivity over specificity by using the highest level of evidence available.…”

Análise das modificações dentoesqueletais em pacientes submetidos à expansão rápida de maxila assistida cirurgicamente

“…Nos modelos de gesso também houve aumento significativo das distâncias entre cúspides caninas, cúspides mesovestibulares dos primeiros pré-molares e cúspides mesovestibulares dos primeiros molares, demonstrando que houve uma expansão linea r da a rcada e não apenas inclinações dentárias. É importante salientar que, mesmo no procedimento de expansão maxilar assistida cirurgicamente, podem ocorrer movimentações dos dentes posteriores, visto que simultaneamente à abertura gradual da sutura palatina mediana a força liberada pelo aparelho expansor provoca a compressão do ligamento periodontal, com inclinação lateral dos processos alveolares, podendo causar vestibularização dos dentes posteriores [9].…”
