Success in guided tissue regeneration (GTR) is dependent on what key factor?

In guided tissue regeneration (GTR), the presence of keratinized soft tissue is a crucial factor for success. Keratinized tissue provides a stable and resilient surface that can protect the underlying regenerative materials and promote proper healing. This type of tissue has a higher barrier to bacteria and can help maintain the integrity of the surgical site.

Keratinized tissues also play an important role in creating an environment conducive to periodontal regeneration by allowing for better attachment of the gingival epithelium, which can positively influence the overall clinical outcomes in GTR procedures. The stability and quality of keratinized tissue around the surgical site are significant for the formation of a functional attachment and the prevention of post-surgical complications.

Other factors like the patient's oral hygiene and vascularity are also important in periodontal healing and regeneration but are secondary to the role of keratinized tissue in providing a successful biological foundation for GTR. The extent of gingival recession may indicate the need for GTR but does not directly influence the regenerative process as much as the quality of the keratinized soft tissue surrounding the area.
