Clinical research of guide bone regeneration and guide tissue regeneration on bone loss of furcation involvement of periodontitis;

Guided tissue regeneration in the treatment of class Ⅱ-Ⅲ teeth furcation defects;

Objective:The objective of this study was to investigate clinical significance of the guided tissue regeneration (GTR) by using Biomesh membrane to the treatment of Class Ⅱ furcation defects.

Objective The purpose of this study was to evaluate the effectiveness of platelet-rich plasma(PRP),bovine porous bone mineral(BPBM)and guided tissue regeneration (GTR) used in combination,compared to GTR alone in the treatment of grade Ⅱ molar furcation defects in dogs.

Clinical analysis of the therapy and crown of mandibular molars with furcation involvement;

Clinical evaluation of apically repositioned flap in the treatment of Class Ⅲ furcation involvements;

Observation of masticatory efficiency of molar with furcation involvement after separating roots

Levels of glycosaminoglycans in gingival crevicular fluid of patients with periodontal degree II furcation involvement before and after guided tissue regeneration.;

Because of the complication and variation in anatomy and cause, the treatment of root furcation lesion was very difficult.

To provide the comparison and initial basis in the further clinical application of LIPUS, we established mandibular premolar classⅡfurcation involvement model and canine periodontal fenestration wounds model, and explored the effect of LIPUS combined with autogenous bone graft or GBR treatment on periodontal tissue repair in beagle dogs.
