THE COMBINED GRAFT TECHNIQUE ISTVAN URBAN ’ s minimally invasive approach to create a maximum amount of keratinized tissue .
When building bone in a large defect , …
... we face a large displacement of the mucogingival line and vestibular loss due to larger bone volume we have to cover , …
... and we need a huge graft to regenerate the lost keratinized tissue .
A very painful experience for the patient that results in poor esthetics !

Shortly after a Geistlich Biofunctionality meeting – discussion about how to create additional keratinized tissue after bone regeneration in large defects .
But there is no keratinized tissue left in such a site to be collected . There is only mucosa and a lot of distortion !
Geistlich Mucograft ® is a good cell collector . Can we use it to correct the large mucogingival defects ?
It should be something we can do ?!
Hmm … maybe we can transplant a mini free gingiva strip around the matrix … It will work as a source for cell migration and ingrowth into the matrix .
R & D
Yes , let ’ s do a study on this . I know that patients appreciate if we harvest only a tiny strip of 2-3 mm instead of a huge free gingival graft .
This actually makes a lot of sense . Let ’ s plan a pilot study !
