dem alleinigen Membranverfahren zu erwarten ?
Deep intra-osseous defects represent a major challenge for the clinician. Sites with intraosseous
lesions have been shown to be at higher risk of disease progression in subjects who
had not received systematic periodontal therapy. Reconstructive procedures have been used
with varying success during the past decades to accomplish the restitutio ad integrum of lost
attachment apparatus in deep intraosseous defects. One of the most investigated method to
achieve the reconstruction of intraosseous defects is to combine the access surgery with the
placement of bone grafts or implant biomaterials into the debrided bony lesion with the goal
to regenerate the lost periodontal tissues. Grafting biomaterials include autogenous grafts,
allogenic grafts, xenogenic grafts and alloplastic materials. The assumption behind the clinical
use of GPs is that the complete regeneration of the attachment apparatus (including new
bone formation and new connective tissue attachment) would be enhanced by the various
biomaterials due to their osteogenetic potential (if the graft would contain viable bone- forming
cells), osteinductive capacities (exerted by the release of bone-inducing substances), or
osteoconductive properties (i.e. the possibility to create a scaffold to support bone formation).
Overall, observational and controlled trials have generally reported an additional benefit in
terms of soft and hard tissue improvements following the use of GPs. However, due to the
large variety of graft biomaterials proposed on the market, the magnitude of such improvements
as well as the consistency of the advantage achieved when GPs are compared to an
access flap procedure need to be determined yet. The presentation will focus on the effect
of the use of grafting procedures in addition to conventional open flap debridement in the
treatment of deep intraosseous defects. Specific advantages of the grafting procedures when
compared to membrane-supprtive reconstruction will also be analyzed.
