ABSTRACT
Objective: To discuss the therapeutic effect of related periodontal surgical treatment and aesthetic rerepair in the patient with residual root and crown of anterior teeth induced by unfitting prosthesis and to clarify the curative effect of periodontal surgical treatment and aesthetic re-repair in the anterior teeth area, and to provide guidance for making the program of clinical treatment. Methods: Two years after repair of the anterior teeth of a patient, the restorations loosed; on the one hand the patient had a toothache of chewing food accompanying gingival bleeding, on the other hand the upper labial frenum was too high, furthermore the upper left incisor apical area showed low density images. After the consultation of periodontics, endodontics, prosthodontics and other disciplines doctors, anterior teeth root canal re-treatment and periodontal basic treatment were adopt as well as crown lengthening combined with labial freneetomy to restore the normal biological width, additionally apply not only guided bone regeneration (GBR) but also platelet rich fibrin (PRF) to repair the defects of apical bone. One month later, provisional restorations were put into use and then three months later permanent repairs were conducted. Results: The corresponding gingival and gingival papilla shape recoverd perfectly and the height of gingiva coordinated with that of adjacent teeth, in the meantime the upper labial frenum attached normally and there was not obvious space between upper incisors; the morphology and function examination of restoration in maxillary anterior region were both well. The follow-up X-ray showed that the bone density of the defect area was the same as that of the peripheral bone without obvious boundaries. Conclusion: The aesthetic repair of thin biotype referring to anterior area, especially in the complicated re-treatment cases, the intervention of the appropriate periodontal surgical treatment is not only beneficial to obtain the obvious short-term effect, but also positive to stabilize longterm effects.
