Abstract
Lack of adequate width and thickness of periodontal or peri-implant soft tissues can compromise the aesthetics, function or survival of teeth and dental implants. Biomaterials are widely used in dentistry to overcome the disadvantages of autogenous tissue transplantation. The advantage of using biomaterials is that there is no need for re-surgery and that they are available in large quantities. The most widely used biomaterial for soft tissue augmentation is collagen, as it is believed to best mimic the natural cellular environment of the extracellular matrix, although other biomaterials are also candidates for soft tissue regeneration. Collagen matrices differ in composition, three-dimensional structure, elasticity and mechanical stability. Aim. is to review the literature on the optimization of regeneration at the stages of soft tissue augmentation using a collagen matrix.
Highlights
The absence of keratinized gingiva around dental implants increases the susceptibility of peri-implant tissues to bacterial biofilm-induced alteration [1]
Does a lack of keratinized gingiva contribute to plaque accumulation around teeth and implants, but it can lead to soft tissue recession in the aesthetic zone
Studies showed that soft tissue recession around the implant might be the result of soft tissue remodeling around the dental implant
Summary
The absence of keratinized gingiva around dental implants increases the susceptibility of peri-implant tissues to bacterial biofilm-induced alteration [1]. Does a lack of keratinized gingiva contribute to plaque accumulation around teeth and implants, but it can lead to soft tissue recession in the aesthetic zone. The presence of keratinized gingiva is closely related to optimal soft and hard tissue health. This is true for patients who maintain proper plaque formation control. Lack of keratinized gingiva was associated with plaque formation, greater soft tissue recession, and more areas that required additional surgical intervention. The above indicates that implants not surrounded by keratinized gingiva are more prone to plaque accumulation and soft tissue recession, despite adequate oral hygiene and supportive periodontal therapy [7]
