conclusions along with the technological advancement, different materials are employed according to the size of the cranium defect and the age of the case. the application of split costa cranioplasty for the small cranium defects in the region of patient’s face is the method with the least possibility of complications, and its cosmetic and functional results are quite promising. introduction os...

background: there are multiple methods for acceleration of bone healing. bone marrow has been shown to contain osteoprogenitor cells.   objective: to determine the effect of percutaneous bone marrow injection on bone healing.   methods: 15 mature, 2-kg-weighing white new zealand rabbits from both sexes were randomized into 3 groups: group i: only osteotomy of right radius was performed and a 5 ...

Background: Tissue engineering using Stem cell from Human Exfoliated Deciduous Teeth (SHED) and a natural biomaterials biomaterial scaffold has become a promising therapy for the alveolar bone defect. The aim of this study was to analyze the Osteoprotegerin (OPG) and Receptor Activator of NF-Κb ligand (RANKL) expression after the application of Hydroxyapatite scaffold and SHED.Methods: A labora...

Bone defects, which can be caused by factors such as trauma, tumor, or osteomyelitis, are clinically common. They lessen the weight a bone is able to bear and cause severe pain patient. Although transplantation gold standard for treating it not suitable all patients due its poor availability, risk of spreading disease, possibility requiring secondary surgery. cement filler defects fill any shap...

Introduction: Stafne’s Bone Cavity [SBC] is a rare, well-defined, mandibular bone lesion, which was first discovered by Edward C. Stafne in 1942. Objective: The purpose of this article to evaluate digital diagnostic approach (SBC) through review and description some clinical cases. Methods: conducted an analysis the literature all articles published on Cavity. We report case 55-year-old male pa...

the purpose of this study was to evaluate the efficacy of two types of bone substitutes, bio-oss and nuoss, for repair of bone defects.this study was performed on the calvaria of 14 new zealand rabbits. the 6mm critical size defect (csd) models of bone regeneration were used. three csds were created in each surgical site. the first defect was filled with nuoss, the second one with bio-oss and t...
