Tissue Preservation Clinical Trial
Official title:
Proof of Concept: Intra-oral Soft Tissue Preservation of Extraction Sockets in Anterior Upper Jaw
It is planned to evaluate if a porcine collagen matrix (Mucograft Seal) is offering comparable results to free gingival grafts (FGG) in post-extraction tissue preservation. If so, this would provide a substantial benefit to the patient as the second intervention on the palate and the subsequent morbidity of the donor site is omitted.
In a proof of concept 5 groups are compared in preserving soft- and hard tissue after tooth
extraction in the esthetic zone:
1. Mucograft® Seal + Bio-Oss®
2. Free Gingival Graft (FGG) + Bio-Oss®
3. Free Gingival Graft + Gelatine sponge (Spongostan®)
4. Spongostan®+ Mucograft® Seal
5. Spongostan®
Volumetric changes of hard and soft tissues are recorded , 2/4/8 weeks and 3/6/12 months
after extraction.
