The Combined Effect of Two Different Tooth Movement Acceleration Methods on Upper Molar Distalization
Abstract
Objective: To investigate the effects of piezocision, low-level laser therapy and their combined application on upper molar distalization.
Subjects and Methods: A total of 40 adolescents aged 14-18 years were enrolled in this randomised controlled clinical trial with 4 groups in a split-mouth study design. The groups consisted of piezocision (P), low-level laser therapy (LLLT), combined (CB) and control (C). After alignment and levelling of the upper teeth with used fixed orthodontic appliances, a mini screw-supported molar distalization appliance was placed palatally and an open coil spring was placed buccally. An equal force (200g) was applied distally to the maxillary first molars from both the buccal and palatal sides. P, LLLT, and their CB application methods were used to accelerate tooth movement with the onset of upper molar distalization, except for group C. To evaluate tooth movements, measurements were performed on three dimensional digital dental models and lateral cephalometric radiographs obtained from individuals. The significance level was set at p<0.05.
Results: In terms of the acceleration of distal movement of the upper molars, this study found a statistically significant difference between the groups. In particular, the combined group had the highest rate of tooth movement, while the control group had the lowest rate. However, no statistically significant difference was observed between the P and LLLT groups.
Conclusions: The combination of non-invasive (LLLT) and minimally invasive (P) techniques in the distalization of upper molars has a positive effect on the acceleration of distal tooth movement.
