OHRQoL assessment using OHIP-14 between sliding anterior retraction with self-ligating brackets and micro-osteoperforations for accelerated orthodontics in orthognathic surgery patients who were assigned for pre-molar extraction and decompensation
Our patients are participants in a randomized clinical trial, an ongoing study about the effectiveness of micro-osteoperforations to accelerate tooth movement. The study sample consisted of 22 consecutive subjects - 12 females and 10 males - between the ages of 18 and 35, who were selected for ortho-surgical treatment and pre-molar extraction assigned for decompensation. The participants were randomly allocated to two groups: control (anterior retraction was performed using implant-assisted sliding mechanics with self-ligating brackets) and experimental (micro-osteoperforations were performed in the activation appointments for anterior retraction using implant-assisted sliding mechanics). For immediate and follow-up assessment of patients' perceptions, comparing regular orthodontic activation and activation with Accelerated Orthodontics, subjects were asked to complete an electronic questionnaire OHIP-14, to assess the participants' comfort level, experiences, and QoL impact.
Exclusion Criteria:
Minimally invasive micro-osteoperforations procedure used to achieve accelerated orthodontic tooth movement. Topical and local anesthetic will be delivered in the area to be treated in accordance with standard practice
Procedure: micro-osteoperforations
Anterior retraction after premolars extraction will be done conventionally (sliding mechanics)
Three vertical micro-osteoperforations, using Excellerator, in the buccal extracted site were executed following the aseptic procedure and local anesthesia
Comparision of OHRQoL between groups - OHIP-14A
comparision of OHIP-14A results between groups after appointment for anterior retraction: The sum of the numeric scores for each participant in all 14 items, with a maximum score of 56 (4x14);
Time frame: 4 days
Comparision of OHRQoL between groups - 7 domains
comparision of each OHIP-14 domain results between groups after appointment for anterior retraction: To evaluate which domains had the most impact during the trial, the answers for each question were combined as pairs and summed for statistical analysis.
Time frame: 4 days
