The Zygomatic Bone
Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more
Age related: As teeth are repositioned alveolar bone remodels to support the teeth within the limits of basal bone support. Talk to a qualified orthodontic specialist who will know the limits your body impose on your expected orthodontic result. ...Read more
Treatment for undisplaced fracture or bone bruise of posterior medial talus and articular surface, and minor bone bruise distal calcaneous?
Unclear question: Bone marrow edema is not a clinical entity. If you have swelling in the foot or ankle, that could be due to many reasons, e.g., local injury, or abnormal veins; if both sides are affected, then it may be due heart failure, low blood protein, and side effect of some medications. ...Read more
Access: Good question. 1) bone marrow is present in multiple locations including the "long bones" (arms, legs), sternum, and hips , 2) the psis - posterior superior iliac spine (hip) is relatively flat with a thinner cortex, so is easier to access and is not near vital structures (like the heart and lungs). ...Read more
Regeneration?: Bone grafting mostly produce a regeneration effect, which meant eestablish a loss bone height (hard to achieve in horizontal defect) or bone width (easily achieved). Your jaw bone growth can only achieved with bmps (bone morphogenetic proteins) and patient should be at young age. ...Read moreSee 1 more doctor answer

Do granules of a dental bone graft move around? Like under your interior jaw bone near the extraction site.
Hopefully minimal: One of the reason why the bone graft fail is the instability or movement of the graft. True grafting required graft stabilization with membrane, cages (titanium fixture to protect graft), or screw in the case of block graft. Micromovement of graft will hinder the fibroblast migration and adhesion and interupt vascular genesis. Must achieve good clotting and full closure for graft stabilization. ...Read moreSee 2 more doctor answers
Will a nondisplaced tibia fracture(not growth plate fracture) change the height of the bone once fully healed?
What are the short/long term effects of a hairline skull fracture. 3" in length from lambdoid suture forward toward the temporal bone.
Usually none: In an adult, the type of fracture you describe really has no long-term effects. Short term problems really have to do with any associated intracranial problems (hemorrhages, contusions, etc.). Potential fractures requiring treatment are ones that are exposed through the scalp (open), significantly depressed, ones involving skull sinuses, which can leak csf, or "growing" fractures in young children. ...Read moreSee 1 more doctor answer
One process is: Greater. In osteoporosis, bone resorption is more prevalent then bone formation. As a result, a negative bone balance occurs and bone loss will occur and over time osteopenia or osteoporosis will occur. Medications such as Fosamax and Boniva (ibandronate) slow down bone resorption. ...Read more
