Abstract

BACKGROUND: The present study was to compare and evaluate the clinical outcome of soft tissue defects in Class I Seibert’s Ridge following soft tissue augmentation with the absorbable collagen (CollaCote™) impregnated with platelet rich plasma to autogenous connective tissue graft. MATERIALS & METHOD: Eighteen patients were selected from the Outpatient pool of the Department of Periodontics, Ragas Dental College & Hospital, Chennai for this comparative clinical trial. The horizontal soft tissue ridge was augmented using absorbable collagen (Collacote™) impregnated with platelet rich plasma to autogenous connective tissue graft. All these patients exhibited Seibert’s type I ridge defect, in the anterior region. Prior to their enrollment in to the study the entire surgical procedure and its outcome were explained to the patients following which an informed consent was obtained. All selected patients were assessed clinically for mean width of keratinized gingiva, changes in papillary height, horizontal dimensional change at mesial, midbuccal and distal region and vertical defect morphology at baseline and after 3 month follow-up. Statistical analysis was done using non parametric test- ‘Mann–Whitney U test’. RESULTS: At the end of the 3 month period, there was no significant increase in the mean width of keratinized gingiva or vertical defect measurement in both the test and the control groups. However, there was a significant average increase in the horizontal dimension of the ridge in both the test and the control groups . (82% in group A and 79% in group B). Similarly, papillary height measurements in group B(control) showed an average increase of 1.39±0.22 when compared to group A(mesial papailla-1.72±0.51,distal papilla-1.67±0.43). CONCLUSION: The present clinical study clearly demonstrates the use of the collagen sponge (Collacote™) impregnated with PRP to that of Connective tissue graft as a predictable treatment modality in the soft tissue defect of Seibert’s Class I ridge regardless of the initial gingival biotype, indicating that the thin gingival biotype can be converted to the thick gingival biotype morphologically and behaviouraly after this procedure. In patients with thin palatal mucosa where the connective tissue of proper thickness cannot be harvested, CollacoteTM with PRP can be a viable alternative to CTG in treating soft tissue ridge defects.
