Clinical effect of orthodontic-repair combined therapy for maxillary anterior teeth dentition defect with malocclusion

Objective To investigate the clinical effect of orthodontic-repair combined therapy in the treatment of maxillary anterior teeth dentition defect and malocclusion. Methods The clinical data of 68 patients with maxillary anterior dentition defect and malocclusion were analyzed retrospectively.They were divided into control group (repair treatment) and study group (orthodontic-repair treatment) according to the different methods of treatment, 34 cases in each group.The tooth occlusal relationship, the occlusion of the anterior teeth and the arrangement of the teeth, clinical treatment effect and the treatment cost were analyzed.The satisfaction of the patients after treatment was investigated by questionnaire.The debris index and attachment loss index were detected. Results The good rate of tooth occlusal relationship, good rate of anterior teeth coverage and teeth order rate in the study group were 82.35%(28/34), 88.24%(30/34), 94.12%(32/34), respectively, which were significantly higher than those in the control group[58.82%(20/34), 67.65%(23/34), 73.53%(25/34)](χ2=4.53, 4.19, 4.53, P=0.03, 0.04, 0.03). The total effective rate of the study group was 94.12%(32/34), which was significantly higher than that of the control group[70.59%(24/34)](χ2=6.50, P=0.03). The average treatment cost of the study group was (8 124.63±386.58)yuan, which was significantly higher than (2 179.86±276.82)yuan of the control group (t=72.90, P=0.00). The patients' satisfaction of the study group was was 88.24%(30/34), which was significantly higher than that of the control group[52.94%(18/34)](χ2=10.20, P=0.00). The debris index and attachment loss index in the study group were (0.14±0.07), (5.06±1.38), respectively, which were significantly lower than those in the control group[(0.63±0.18), (6.52±1.58)](t=14.79, 14.79, P=0.00, 0.00). Conclusion Orthodontics combined with orthodontic treatment can help to improve the patients' tooth deformity, and the effect is remarkable, which can win the patients' praise, but the cost of the method is high, so patients should be considered in the selection.
