FACTORS AFFECTING THE EFFECT OF MICROIMPLANT TREATMENT FOR ORTHODONTIC PATIENTS

Objective: To investigate the associated factors affecting the therapeutic effect of microimplants for orthodontic patients. Methods: The clinical data of 175 (280 cases) malocclusion patients treated with microimplants from August 2019 to August 2021 were retrospectively collected. These patients were classified into unsuccessful groups (31 cases) and successful groups (249 cases) based on their microimplant loosening failure information. Then, the clinical data from the successful and unsuccessful groups were statistically analyzed, and factors associated with multivariate Logistic regression analysis were used to influence the effect of microimplant treatment for the orthodontic patients. Results: The proportions of patients aged no more than 12 years, with vertical bone plane type and high angle, poor oral hygiene, and mandible implanted with dental arch account for 35.48%, 54.84%, 67.74% and 64.52%, respectively. The proportions were higher than 14.46%, 28.92%, 25.70%, and 28.92% of the successful group (P < 0.05). The results of multivariate Logistic regression analysis showed that the age (<= 12 years), vertical bone plane type and high angle, poor oral hygiene, and mandible implanted with dental arch are the independent risk factors affecting the effect of microimplant treatment of orthodontic patients (OR=1.145, 3.232, 6.290, 5.663, P < 0.05). Conclusion: The risk factors affecting the effect of microimplant treatment in orthodontic patients are the age (<= 12 years), vertical bone plane type and high angle, poor oral hygiene,mandible implanted with dental arch, etc. According to the above factors, orthodontic patients undergoing microimplant treatment can be subjected to targeted treatment and intervention, so as to further improve the success rate of the micro implant treatment.
