Pain and discomfort experience after miniscrew insertion as an anchorage device in orthodontic patients

Introduction: The aim of this study was to evaluate the degree of pain and discomfort experienced for 1 week after miniscrew insertion using a questionnaire survey. Materials and Methods: Thirty-nine miniscrews were inserted in the mandible and maxilla of 33 patients with a self-drilling JB head type miniscrew under local anesthesia. Patients were asked to rate the degree of pain and discomfort experienced on a visual analog scale (VAS) after 1 hour, 12 hours, 1 day, and 1 week . Data were analyzed using the Statistical Package for the Social Sciences version 22 software. Repeated measures analysis of variance (ANOVA) with considering the jaw, side of insertion, and length of miniscrew as a between subject factor was used. Results: There was no significant association between the length of miniscrew (P = 0.448), the jaw (P = 0.870), and the side of the insertion (P = 0.346) and causing pain. The maximum degree of pain experience was in 1 hour after insertion that was 48.79 mm in VAS scores, which started to decrease significantly after 12 hours, 1 day, and 1 week as the minimum intensity of the pain was 1 week after the miniscrew insertion that was 2.31 mm in VAS scores. Conclusion: On the basis of the patient responses, it can be concluded that miniscrew could be an acceptable option in orthodontic treatments.
