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. (More)
A case of an abnormal loop of the extracranial vertebral artery enlarging the intervertebral foramen at C5-C6 and the transverse foramen at C5 is reported. This occurrence is rare and was associated with cervicobrachial neuralgia caused by neurovascular compression of the C6 root. The patient was cured by microvascular decompression.
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)(More)
The penetration of air gun pellets in facial soft tissue can cause major problems during the removal of foreign bodies, although conventional radiography, computed tomography, image-guided surgical removal, and ultrasound have been applied to facilitate the procedure. It was the aim of the present case report to introduce a modified intraoperative method(More)
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(More)
The osteoinductive potential of periosteum and bone can be stimulated by elevating the periosteum in a distraction-like modus, but also by an ad-hoc elevation. This was tested and proved in an experiment in 9 Goettingen mini-pigs with elevation heights of 5, 10 and 15mm. Specially designed and perforated titanium meshes were implanted subperiosteally to(More)
The authors have designed a biocompatible and bioresorbable plate (1) in Phusilines* for anterior cervical interbody stabilization. Phusilines* are polymer of alpha hydroxyacid (poly lactic acid), and their in vivo degradation (in lactic acid and via the Krebs circle, in water and carbon dioxide), is complete within 18 months. Screws are available in the(More)
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. Different elevation/shielding heights of 5, 10, and(More)
The authors report the case of a 62-year-old man referred to the department of oral and maxillofacial surgery because of a clinical suspicion of palate carcinoma. Incidentally, diagnostic radiology showed a metallic foreign body in the left maxillary sinus. Anamnestic data revealed that a shot from an air gun accidentally hit the patient's left cheek in(More)
