Barrier Membranes and Soft Tissue Substitutes in Implant Dentistry: A Focus on Biomaterial Type and Rationale for Use

摘要

The efficacy of tissue regeneration in implant dentistry has been well documented. Augmenting deficient bone and/or bound-down soft tissue with implant placement or as a staged protocol is considered good practice today. When particulate biomaterials are used for bone augmentation, a barrier membrane protects the environment from unwanted cellular invasion. Barriers are either resorbable or need removal after some time. Biomaterials for soft tissue augmentation may be classified as: (1) autogenous (harvested from the patients' palate or tuberosity), (2) allogenic, and (3) xenogenic. The choice of a barrier membrane or a soft tissue substitute depends on the clinical situation, clinicians’ preference and patient acceptance.
