Complications with Surgical Procedures Utilizing Connective Tissue Grafts

Randall J. Harris, DDS / Richard Miller, DDS / Laura Harris Miller, DDS / Christopher Harris, DDS

The goal of this study was to evaluate the incidence and severity of the complications that occur after connective tissue grafts are used. Five hundred consecutively treated patients, for whom connective tissue grafts were used for root coverage or gingival augmentation, were included in this study. Complications did occur, but the rates and intensities seemed clinically acceptable. There was no pain reported in 81.4% of the patients, no bleeding in 97.0% of the patients, no infection in 99.2% of the patients, and no swelling in 94.6% of the patients. None of the factors evaluated in this study were associated with a statistically significant increase in the rate or intensity of complications. These factors included: age, sex of patient, smoking status, purpose of the graft (ie, for root coverage or for gingival augmentation), size of the recipient area, and the location of the defect being treated. Based on the results of this study, the incidence and severity of complications seemed to be clinically acceptable. (Int J Periodontics Restorative Dent 2005;25:449-59.)
