Histological and Clinical Evidence of Soft Tissue Regeneration from a Porcine Collagen Matrix - Case Report
Journal: Advances in Medicine and Engineering Interdisciplinary Research DOI: 10.32629/ameir.v1i2.1240
Abstract
Tooth loss results in loss of hard and soft tissue volume, making it difficult to achieve aesthetically pleasing results. In order to decrease the morbidity caused by an autologous graft in the alveolar seal, it can be replaced by a resorbable matrix of collagen. The present case report evaluated clinically and histologically a porcine collagen matrix, in soft tissue regeneration, during the installation of an implant immediately after dental extraction. After 6 months, clinically, a tissue with an optimal final aesthetic appearance was obtained and histologically, the formation of an epithelial and connective tissue compatible with that of a normal mucosa was evidenced.
