Weinspach, I. Staufenbiel, H. Günay, W. Geurtsen, R. Schwestka-Polly, A.P. Demling] Einfluss kieferorthopädischer Chirurgie auf die parodontalen Gewebe Kurzzeitergebnisse Objective: The present prospective study aimed at evaluating the influence of orthognathic surgery on mucogingival tissues and the subgingival microflora. Patients and methods: Fifteen consecutively-treated patients with a mean age of 24.9±7.7years were included in this study. The surgical interventions comprised the Le FortI osteotomy of the maxilla and/or sagittal split osteotomy of the mandible. The following periodontal and microbial parameters were measured preoperatively (T0) as well as 1week (T1) and 6weeks (T2) postoperatively: pocket probing depth(PPD), gingival recession(GR), clinical attachment level(CAL), bleeding on probing(BOP), plaque index(PI), and changes in the subgingival microflora. Periodontal parameters were calculated for all sites as well as for buccal and oral sites separately. For statistical analysis, the general linear model and paired t test were applied (level of significance: p<0.05). Results: PPD readings increased significantly on oral tooth sites when T0 values were compared to T1 (p=0.009) and T2 values (p=0.042). GR increased significantly on buccal sites from 0.10±0.16mm at baseline to 0.21±0.23mm at T1 (p=0.013) and 0.31±0.31mm at T2 (p=0.001). Furthermore, we noted significant changes in the CAL (oral sites) and PI (buccal and oral sites). We observed no significant differences in BOP and periodontopathogenetic bacteria. Conclusion: Orthognathic surgery has a statistically significant effect on the development of gingival recessions. However, this effect may not necessarily clinically impair the esthetic appearance.
