[Clinical study of prosthetic gingival reconstruction in vertical bone defect patients].

OBJECTIVE

To evaluate the preliminary clinical results of prosthetic gingival reconstruction in vertical bone defect patients.

METHODS

The study included 31 partial or edentulous patients (male 22, female 9) with 152 implants supporting fixed prostheses from February 2002 to January 2011 in Peking University School and Hospital of Stomatology. The implant-supported fixed prostheses with artificial gingival material to compensate for vertical defect were delivery after implant healing period. At time of prostheses delivery, a panoramic radiograph was taken. The results were evaluated according to California Dental Association by two prosthodontists. Clinical observation included survival of the implants, integrity of the restoration, complication of prosthesis and degree of satisfaction of the patients.

RESULTS

A total of 152 implants supported fixed prostheses with artificial gingival materials to compensate vertical bone defect were delivered. No implants lost, and the survival rate was 100% during the follow-up period. The sore of acceptance of prosthesis was 96.8%. All patients were satisfied with the clinical results.

CONCLUSIONS

The artificial gingival reconstruction technique is feasible for vertical bone defect patients.
