Simplified protocol for horizontal and vertical post-extractive GBR with intentionally exposed PTFE membrane - Case series
Cappellin MR
Abstract
Purpose: Post-extractive sites often need soft and hard tissue regeneration in order to place implants with optimal functional and aesthetic conditions. The author proposed several techniques for bone preservation and regeneration: most of them requires release incisions and coronally advanced flap to obtain primary closure, so regain a correct alignment of keratinized gingiva makes mandatory a further surgery with a connective tissue graft from secondary surgical site.
Case report: Since May 2018 we applied with some adjustments Open Barrier Technique (proposed by E. Funakoshi, 2005) in 152 post-extractive alveolar preservation and GBR; after 3-6 months we placed 194 implants, with 100% success and survival rate.
Conclusions: Our simplified protocol allows performing vertical and horizontal GBR in post-extractive sites without release incisions: non resorbable PTFE membrane protects wound and bone graft for 6-8 week; secondary healing ensures thick keratinized tissue and bone maturation, suitable to place implants after 3-6 months.
