Soft Tissue Defects: CTG and Dermis
Soft tissue defects in dental treatments can vary widely, requiring different approaches depending on the specific circumstances. When there is adequate keratinized tissue (KT), the need for an autogenous graft can often be avoided. For instance, in a case involving gingival recession, teeth #4 and #5 were effectively treated with Dali Dermal Allograft, while tooth #6 was treated using an autogenous connective tissue graft. Nine months post-treatment, the areas showed successful root coverage with natural contours, thickness, and tone.
In terms of dermal allografts vs CTG, there have been several studies comparing the two approaches and the research suggests that dermal allografts can achieve comparable results to connective tissue grafts in specific cases. (1,2)
