A subepithelial connective tissue graft takes tissue from under healthy gum tissue in the palate, which may be placed at the area of gum recession. This procedure has the advantage of excellent predictability of root coverage, [19] as well as decreased pain at the palatal donor site compared to the free gingival graft. The subepithelial ...
The term free describes how the graft is completely removed from the donor site rather than remaining attached via a pedicle. The term autogenous, from the Greek root auto-("self"), describes how the individual who receives the graft is the same individual who provides the donor tissue. [3] The connective tissue is generally taken from the hard ...
A free gingival graft is a type of gingival grafting performed to correct acquired deficiencies of the gum tissue around teeth or dental implants.Besides autologous tissues, xenogeneic collagen matrices are using for gingival augmentation after dental implantation. [1]
Guided bone regeneration (GBR) and guided tissue regeneration (GTR) are dental surgical procedures that use barrier membranes to direct the growth of new bone and gingival tissue at sites with insufficient volumes or dimensions of bone or gingiva for proper function, esthetics or prosthetic restoration. Guided bone regeneration typically refers ...
The gingival fibers, (H), extend from the cementum (B) into the attached gingiva. Some fibers extend coronally into the crest of the free gingiva, some horizontally, and still other extend horizontally over the crest of the alveolar bone, (C), and then apically to connect on the facial aspect of the buccal plate of the alveolar bone.
This technique is adopted when gingival margins and crystal bone height are to be maintained at their pretreatment locations. Fiberotomy is performed at 7-10 day intervals during treatment. A scalpel is used to sever supracrestal connective tissue fibres, thereby preventing crystal bone from following the root in a coronal direction. [citation ...
The supracrestal attachment apparatus is composed of two layers: the coronal junctional epithelium and the more apical gingival connective tissue fibers. [1] The two layers together form the thickness of the gingival tissue, and this dimension is termed the biologic width .
The alveolar bone (C) is surrounded for the most part by the subepithelial connective tissue of the gingiva, which in turn is covered by the various characteristic gingival epithelia. The cementum overlaying the tooth root is attached to the adjacent cortical surface of the alveolar bone by the alveolar crest (I) , horizontal (J) and oblique (K ...
