Clinical study of biomaterial collagen type i, no cross-link, in the treatment of gingival recession in humans

Background

The current techniques available for root coverage have advantages and limitations, with different results and patterns of repair. In the literature, several effective surgical techniques for the treatment of gingival recessions, using the gingival conjunctive tissue graft. Biomaterials composed of collagen have biocompatibility and ability to promote wound repair, in addition to its natural biological potential, which enables a favorable environment for regeneration, making collagen a highly preferred biomaterial for root coverage.

Aim/Hypothesis

Clinical evaluation of the no-cross link, type I collagen biomaterial for treatment of the Miller's class I or II gingival recessions, in humans.

Material and Methods

The sample consisted of 24 gingival recessions in canines and or maxillary and mandibular premolars. Periodontal parameters- depth of probing (DP), clinical level of insertion (NCI), degree of root coverage (RC), keratinized mucosa (KM) and thickness of the free gingival margin (TFGM) at 90 and 180 days+ measured using the Digital Periodontal pachymeter and the UNC 15 probe. The clinical results were analyzed by the Wilcoxon statistical tests.

Results

Results at 180 days, there was no significant change in DP, KM and TFGM, significant for NCI and root coverage were observed demonstrating a reduction of the gingival recession (70% at 90 days and 58% at 180 days).

Conclusion and Clinical Implications

The results of this study indicating the necessity of using membranes with better biological and clinical behavior.
