Analysis Of Related Factors In Orthodontic Treatment Of Gingival Recession

[Objective]This study through the analysis of orthodontic treatment in patients with age, sex, extraction or nonextraction treatment, periodontal status, malocclusion type, congestion, CEJ to alveolar crest distance and inclination and protrusion of the upper and lower central incisors, is further explored the related factors of gingival recession during orthodontic treatment,and provides a theoretical basis for clinical prevention of gingival recession.[method]To select 200 cases of patients receiving orthodontic treatment,age 12-30 years old, Straight wire appliance technology is used. This experiment adopted panoramic radiograph, cephalometric, intraoral photography and model et al, to statistically analyze the patient’s age, sex, extraction or nonextraction treatment, periodontal status(gingival biotype, oral health status, gingival recession), malocclusion type, congestion, and CEJ to alveolar crest distance and the change in inclination and protrusion of the upper and lower central incisors before and after orthodontic treatment, We go to explore the prone factors of gingival recession in orthodontic treatment.[Results]1.Age, sex and oral health status was not associated with gingival recession(p>0.05). 2.Malocclusion in vertical growth pattern and crowding associated with gingival recession, the patients with high angle is more prone to gingival recession than the patients with low angle and average angle; The degree of congestion is the heavier, the incidence of gingival recession is the more frequently. Sagittal malocclusion types is not associated with gingival recession.3.The formation of gingival recession and whether extraction treatment are significantly correlated(p=0.002), Extraction treatment is more likely to cause tooth gingival recession.4.Thin gingival biotype is more susceptible to gingival recession, the same gingival biotype mandibular gingival recession occurred relatively higher rate than maxillary.5. CEJ- the alveolar crest increases, that is, the more resorption of the alveolar bone, and gingival soft tissue will shrink. 6.There was no correlation between the change in inclination and protrusion of the upper and lower central incisors and the appearance of the gingival recession before and after orthodontic treatment,[Conclusion]The results of this research show that the formation of gingival recession and extraction treatment, gingival biotype, vertical growth pattern of the malformation, congestion, alveolar bone absorption, has a close relationship.The formation of gingival recession and age, gender, sagittal malocclusion type, oral health status and the upper and lower incisor faciolingual inclination movement has no correlation. However, clinical gingival recession is often the result of many factors, so we should consider various prone factors comprehensively.
