Document Type and Number:
WIPO Patent Application WO/2012/012269
Kind Code:
A3
Abstract:
Biodegradable stents and methods for selectively guided tissue regeneration in treating a periodontal defect adjacent to a root of a tooth are provided. The biodegradable stents and methods comprise a coronal portion and a transverse portion or shelf, which reduce unwanted migration of gingival epithelium, gingival connective tissue, and soft tissue and enable the cementum and periodontal ligament cells to re-establish the periodontal ligament in a proper sequence resulting in a new periodontal attachment.
