Injectable Tissue-Engineered Soft Tissue for Tissue Augmentation
Soft tissue augmentation is a process of implanting tissues or materials to treat wrinkles or soft tissue defects in the body. Over the years, various materials have evolved to correct soft tissue defects, including a number of tissues and polymers. Autogenous dermis, autogenous fat, autogenous dermis-fat, allogenic dermis, synthetic implants, and fillers have been widely accepted for soft tiss...
متن کاملSafety data of injectable nonanimal stabilized hyaluronic acid gel for soft tissue augmentation.
BACKGROUND Nonanimal hyaluronic acid gel was recently developed for soft tissue augmentation and volume expansion and has been shown to offer several advantages in comparison to other augmentation materials. There are rare reports of adverse events believed to be secondary to trace amounts of proteins in the hyaluronic acid raw material. OBJECTIVE To determine the safety profile of nonanimal ...
متن کاملThe history of injectable silicone fluids for soft-tissue augmentation.
BACKGROUND The debate over the legitimacy of silicone as a safe tool for soft-tissue augmentation has spanned well over half a century. Proponents concede that injections of questionable purity and/or of massive quantities have produced unfavorable outcomes. They assert that in experienced hands with "injectable-grade" silicone, there are very few problems. Despite these claims, the literature ...
متن کاملSoft Tissue Augmentation with Silk Composite Graft
PURPOSE The objective of this study was to evaluate the interaction between 4-hexylresorcinol (4HR) and antibody as that affects the performance of a silk-4HR combination graft for soft tissue augmentation in an animal model. METHODS The silk graft materials consisted of four types: silk+10% tricalcium phosphate (TCP) (ST0), silk+10% TCP+1% 4HR (ST1), silk+10% TCP+3% 4HR (ST3), and silk+10% T...
متن کاملMechanical properties of highly porous PDLLA/Bioglass composite foams as scaffolds for bone tissue engineering.
This study developed highly porous degradable composites as potential scaffolds for bone tissue engineering. These scaffolds consisted of poly-D,L-lactic acid filled with 2 and 15 vol.% of 45S5 Bioglass particles and were produced via thermally induced solid-liquid phase separation and subsequent solvent sublimation. The scaffolds had a bimodal and anisotropic pore structure, with tubular macro...
