Effect of three different maxillary expansion appliances on root resorption

Aim: The study was to examine rapid maxillary expansion (RME), semi-rapid (SRME), and slow (SME) compare the root resorptions occurring in supporting upper first premolar teeth during treatment by using micro-computed tomography (micro-CT). Methodology: Thirty individuals that required tooth extraction were divided into three groups consisting of 10 for RME, SRME, SME. RME group, molar with hyrax screw activated ¼ tour twice daily banded appliances. SRME acrylic-bonded appliances per morning night until opening suture. Upon suture, it every two days sufficient gained. SEM quad helix 20 days. After 12 weeks retention period, extracted. scanned Micro-CT (SkyScan 1172, Kontich, Belgium), images analyzed a Dell Precision T5500 determine resorption crater volumes. Results: In all samples, craters concentrated on buccal surfaces roots. highest volume, total observed followed least volume detected SME group. Conclusion: Since exposed more force surfaces, most seen How cite this article: Topal R, Gündüz Arslan S. Effect different resorption.
