Patient’s Perception of Pain in Treatment with Temporary Anchorage Devices (Micro-implant, Mini-implant and Mini-plate): Intragroup and Intergroup Analysis

Currently, temporary anchorage devices (TADs) are being used in orthodontic treatments for skeletal anchorages. However, patients remain apprehensive regarding the use of this novel concept in orthodontic procedures. The purpose of this study was to compare the differences and the change in pain perception after treatment using TADs (micro-implant, mini-implant and mini-plate). Fifty-seven TADs (20 micro-implants in the infrazygometic crest, 19 mini-implants in the posterior paramedian palate and 18 miniplates in the infrazygometic crest) were inserted as skeletal anchorages. The visual analog scale (VAS) was used to evaluate and compare the patients’ perception of pain for 3 TADs procedures. The repeated-measure general linear model (GLM ) was used in the analysis of intragroup. One-way ANOVA was applied to analyze the data from intergroup and followed by the Tukey's HSD (honestly significant differences) test for post hoc comparisons. One day VAS after TADs placement, mini-implant group (56.8) and mini-plate group (59.5) were significant greater than microimplant group (30.8) and no difference between mini-implant group and mini-plate group. Seven days VAS after TADs placement, mini-plate group (27.2) and mini-implant group (10) weren’t significant than micro-implant group (17). However, mini-plate group were significant greater than mini-implant group. The TADs could enhance the effectiveness and efficiency of orthodontic treatment, and the patients could endure the pain and discomfort during the TADs treatment.
