Gingival Fibers There are functions: • To brace the marginal gingiva firmly against the tooth. • To provide the rigidity necessary to withstand the forces of mastication without being deflected away from the tooth surface. • To unite the free marginal gingiva with the cementum of the root and the adjacent attached gingiva. • The gingival fibers are arranged in three groups: gingivodental, circular, and transseptal 12 June 2008 Year 3 Block Head & Neck 40
