[The clinical results of combined periodontal-orthodontic treatment on patients with periodontitis and labial displacement of incisors].
OBJECTIVE
To evaluate the clinical effects of combined periodontal and orthodontic method in treating labial displacement of anterior teeth caused by periodontitis.


METHODS
21 cases with periodontitis and fly-out of anterior teeth were selected. After the inflammation was controlled by essential periodontal therapy, the anterior teeth were allied by edgewise appliances; meanwhile, periodontal care and occlusal adjustment were conducted to control inflammation and occlusal trauma, until normal occlusion was established. A total of 74 teeth were treated, the periodontal probing depth and the degree of alveolar ridge resorption was recorded before and after treatment, respectively. All the data were statistically analyzed by Ridit test and Chi-square test.


RESULTS
After 1-2 years of follow-up, all cases under 40 years got satisfactory effects, with significantly decreased periodontal probing depth (P<0.01) and alveolar ridge (P<0.05).


CONCLUSIONS
Combined periodontal and orthodontic treatment was effective in the management of periodontitis, occlusal trauma and teeth alignment, and the effects were stable for a relatively long period. But patients over 40 years was not suitable for the treatment.
