Vertical augmentation with RPMTM
Re-inforced PTFE Mesh, RPMTM, can be easily trimmed, adapted, and fixed with pins. RPMTM offers a high stability and the secluded space can be augmented with a mixture of Geistlich Bio-Oss® and autologous bone. Geistlich Bio-Oss® provides long-term volume stability10, and autologous bone contain the required osteoinductive properties for vertical augmentation11. The autologous particulated bone graft can be harvested from the mandibular ramus using a bone scraper device9,11.
PTFE membranes have a long-standing history as barrier membranes and are highly biocompatible6. Collagen membranes, such as Geistlich Bio-Gide®, have been shown beneficial for uneventful soft tissue healing12,13 in guided bone regeneration (GBR) procedures resulting in low complication rates12. Thus, potential exposures can be anticipated by covering non-resorbable mesh with Geistlich Bio-Gide® to get a better soft tissue healing12,13. Moreover, both, Geistlich Bio-Gide® and RPMTM follow the concept of biofunctional membranes that allow early vascularization of the graft.
As for all augmentative procedures, soft tissue management is key9,14. This especially comprises:
- Preparation of soft tissues before, during, or after treatment to increase mucogingival thickness and keratinized tissue width
- Elevation of a full-thickness remote or papilla preservation flap
- Periosteal release to advance flap to achieve tension-free closure
- Primary soft tissue closure by horizontal mattress and single interrupted sutures
