Comparison of skeletal and dentoalveolar effects of tooth-and-bone-borne and bone-borne miniscrew-assisted rapid palatal expansion in young adults

Key Points

• To compare the skeletal and dental effects of two types of miniscrew-assisted rapid palatal expansion in young adults.
• Performed rapid palatal expansion using tooth-and-bone-borne (TBB) and bone-borne (BB) systems.
• Evaluated midpalatal suture separation success rates in both groups.
• Measured skeletal and dental expansion outcomes, focusing on dental inclination.
• Both TBB and BB groups achieved similar midpalatal suture separation success rates of approximately 73%.
• Skeletal expansion results were comparable between the two expansion techniques.
• The TBB group showed significantly greater dental inclination compared to the BB group.
