Periosteal elevation induces supracortical peri-implant bone formation.

Purpose: The aim of the study was to evaluate the possibility of supracortical peri-implant bone formation after periosteal elevation.

Materials And Methods: Periosteal elevation with an elevation height of 5 or 10 mm was performed in an animal experiment with 24 female domestic pigs. For this purpose, four implants were inserted in the frontal bone of each animal.

Vestibuloplasty: porcine collagen matrix versus free gingival graft: a clinical and histologic study.

Background: A free gingival graft (FGG) is currently the gold standard for augmenting small areas of keratinized mucosa. The porcine collagen matrix (CM) represents an alternative to autologous tissue harvesting. This study aims to compare the CM versus FGGs for augmenting keratinized peri-implant mucosa based on clinical and histologic evaluations.

Guided bone regeneration in pig calvarial bone defects using autologous mesenchymal stem/progenitor cells - a comparison of different tissue sources.

Due to donor side morbidity and the absence of osteogenic properties in bone substitutes, there is a growing need for an alternative to traditional bone grafting within the scope of tissue engineering. This animal study was conducted to compare the in vivo osteogenic potential of adipose-derived (AD), periosteum-derived (PD) and bone marrow-derived (BM) mesenchymal stem/progenitor cells (MSC). Autologous mesenchymal stem/progenitor cells of named tissue origin were induced into osteogenic differentiation following in vitro cell expansion.

Guided bone regeneration: dynamic procedures versus static shielding in an animal model.

Due to its osteoinductive potential, the periosteum plays a crucial role in the process of neoosteogenesis. Therefore, periosteal elevation can lead to new bone formation in an artificially created space. In this study, we compared dynamic periosteal elevation with static shielding in an animal experiment.

Bone regeneration in osseous defects-application of particulated human and bovine materials.

Objective: Different bone substitute materials are used to manage the challenge of local bone loss subsequent to craniofacial reconstructive surgery. In this animal study we examined the de novo bone formation in bone defects after insertion of Puros Allograft of human origin or Navigraft of bovine origin, and compared the regenerative potential of each material to that of autogenous bone.

Study Design: Using the adult domestic pig as the animal model, we created identical bone defects in the frontal skull and filled them with the different test materials using random assignment.
