The aim of the present study was to evaluate histologically and radiographically the tissue response to dolomite [CaMg(CO3)2] and its osteogenic potential in the repair of bone cavities in the calvaria of rats. A bone defect 10 mm in diameter and 1 mm deep was made in the calvaria of male Wistar rats. The defects were filled with dolomite, inorganic bovine bone (positive control), or coagulum (...

The effects caused by the implantation of bioabsorbable hydroxyapatite (HA) bound to a pool of bone morphogenetic proteins (BMPs) and other bone noncollagenous hydrophobic proteins mixed with anorganic bovine bone inside rabbit bone marrow were assessed. Within the interior of hollow cylindric titanium prototypes, the following biomaterials were inserted: (1) test group: HA containing a pool of...

Bovine milk has been shown to contain bioactive components with bone-protective properties. Earlier studies on bovine milk whey protein showed that it suppressed bone resorption in the female ovariectomised rat. A new osteotropic component was subsequently identified in the whey basic protein fraction, but bone bioactivity may also be associated with other whey fractions. In the present study, ...

Objectives- To assess the ectopic bone formation in canine masseter muscle following the implantation of the natural bovine bone minerals (NBM) loaded with canine mesenchymal stem cells (MSCs).Design- Experimental study.Animals- four mongrel dogs.Procedures- Tripotent MSCs isolated from the canine bone marrow were loaded onto the NBM sponges and allowed to adhere. The cell-loaded scaffolds were...

OBJECTIVE To carry out a radiological and histomorphometric evaluation of bone response to bovine bone implants inserted in rabbits' tibiae. MATERIALS AND METHODS Twenty New Zealand rabbits weighing 3900-4500 g were used. Twenty bovine bone implants (Endobon) in granulated form of 500-1000 μm granulometry were inserted in the proximal metaphyseal area of the animals' right tibia and 20 contro...

This paper introduces the culture preparation of ovine, bovine and human cancellous bone cores to be used in an explants model Zetos. The three dimensional (3D) bone cores were prepared and evaluated for all three animals. Bone cells in vivo constantly interact with each other, migratory cells, surrounding extracellular matrix (ECM) and interstitial fluid in a microenvironment, which continuous...

Background: Tooth extraction is followed by a resorption of the bone in buccal or facial portion, up to 50% first six months after extraction. Bone loss mainly results from damage periodontal ligament complex. Socket preservation surgical procedure aimed maintain an alveolar ridge extraction, eliminating minimizing need for future augmentation implant-prosthetic rehabilitation. techniques use s...

BACKGROUND The performance of implant surgery in the posterior maxilla often poses a challenge due to insufficient available bone. Sinus floor elevation was developed to increase needed vertical height to overcome this problem. The present study described and reported a simple, safe and predictable bone graft mixture for the sinus lifting procedure. MATERIAL AND METHODS Seventy patients were ...
