Will partial dentures decrease the chances of bone loss in the jaw or collapse of jaw due to bone resorption?

---

Once the tooth is removed, regardless of partials isn't the supporting bone in the jaw already dissolving?
No, a denture will not prevent bone resorption. Dentures get looser as time goes on, due to bone resorption. When a tooth is removed, bone resorption starts straight away, and is rapid for the first 3-6 months, and then continues at a slow rate. New dentures proviided straight after tooth removal (immediate dentures) will therefore be a poor fit after just a few months  (+ info)

what is bone resorption and bone formation in osteoporosis pathology?

---

What a great question! Osteoporosis is fundamentally caused by an imbalance in the delicate system that maintains our bones.

Normally, cells called osteoclasts (responding to a hormone called PTH) break down old bone, reabsorb it, and then cells called osteoblasts lay down new bone.

This process continues every minute of every day of our lives - bone is constantly being broken down, recycled, and rebuilt (the term we use for this is 'remodeling').

In osteoporosis, a disease marked by decreased bone mineral density (BMD), this balance between bone breakdown and bone rebuilding is dysfunctional. There are 3 reasons for why/how osteoporosis happens:

1. Something called "peak bone mass" is insufficient. This means that your bones simply don't have the strength to support the required weight. This usually happens during growth (birth to a few years post-puberty).

2. Too much bone resorption. If too much bone is being chewed up and recycled, then the strength of your bones decreases.

3. Not enough new bone being laid down. If osteoblasts aren't doing their job (for whatever reason), then your bones will also be weak.

A tremendous amount of research has gone into better understanding these 3 problems, but the take home message is that osteoporosis is complex. Treatment is also complicated, but fundamentally aims to increase the amount of calcium available for bone formation and to prevent osteoclasts from breaking down bone (this is what the bisphosphonates like Fosamax do - they kill osteoclasts).

Wow - great question and long answer. Hope this helps!  (+ info)

do painkillers have any effect on bone during orthodontic treatment(like delaying deposition/resorption 4 ex.)

---

actually i heard that from an orthodontist but i looked 4 it everywhere and couldn't find such a thing..so did anyone hear about it?
Most of the stuff I can see seems to be related to Non Steroidal Anti Inflammatory medications (ibuprofen, indomethacin, and the like) and COX2 inhibitors (celecoxib, rofecoxib etc)

Furthermore, most of the stuff says that there is no clear evidence that they do.  (+ info)

Any advice regarding abnormal bone growth contributing to tooth root resorption?

---

I went to the dentist after experiencing some diffuse, dull pain in my lower jaw. An xray was taken which revealed an opaque, round mass encroaching on the distal root of tooth #30. The root is almost half dissolved. There is a small abscess on the other root, which may explain the discomfort. I have been referred to an endodontist and an oral surgeon. They both agree that I would benefit from an I CAT dental scan. Right now the insurance companies are arguing on whether it's dental or medical.
I am very concerned about this being osteosarcoma.
Is there a professional who can advise me on what diagnostics to ask for next? I CAT, Biopsy?
See a periodontist  (+ info)

My daughter was just diagnosed with condylar resorption. Anyone else have it and can shed some light?

---

Condlyar resorption is a rare disease and it sounds like every case is a little different. We are looking to find other people who have this condition and want to know what happened in their cases. My daughter is 17 years old and had jaw surgery last year. The condylar resorption just showed up about two months ago. Her bite is now back to the way it was before surgery. She has some pain and we are seeing a chiropractor.
Condylar resorption almost exclusively affects women. Its exact etiology and pathogenesis remain unclear. It has been associated with rheumatoid arthritis, temporomandibular joint internal derangement, condylar fractures, connective tissue or autoimmune diseases, orthodontic treatment, and orthognathic surgery. In most cases, however, there is no identifiable precipitating event, hence the term "idiopathic condylar resorption." The female predisposition to this condition may be attributed to the influence of estrogen and prolactin on the bone response. Treatment of idiopathic condylar resorption is controversial. Condylectomy and reconstruction with costochondral graft offer definitive management of active idiopathic condylar resorption.  (+ info)

What bone would be used in a bone graft to replace the shaft of the radius?

---

My mother was just diagnosed with bone cancer and she was told she would need a bone graft in the shaft of her radius. Which bone whould be likely to be used?
It depends on a number of factors such as how much bone needs to be replaced. Another factor would be the training her surgeon has had.

Most commonly, bone grafts are taken from a persons hip. If the graft that is needed is very large, or there is concern that the bone cancer may have traveled to other bones, they may choose to use either an artificial bone grafting material or a bone that has come from a deceased person that has generously donated their bones.

Unfortunately, this is an answer that can only come from her doctor.

The best of luck to you and your family. May your mother have a speedy recovery.  (+ info)

How does resorption work in the exfoliation of deciduous teeth?

---

Can some one help me out here. Thanks
The pressure of the crown of the permanent teeth pressing against the roots of the baby teeth causes the roots to literally dissolve away. When the baby roots become short enough, there is not enough to hold the the tooth in so they become loose and fall out. The pressure exerted by the permanent tooth on the baby tooth will also help push the baby tooth out.  (+ info)

What is the difference between bone spurs and osteoarthritis?

---

I have been having pain in my hip for a while so i went to the doctor and he said i have bone spurs in my hip. I researched bone spurs and everything keeps talking about osteoarthritis. I am just wondering if that is the same thing or is it caused by osteoarthritis? I also would like to know how to heal bone spurs without surgery if that is even possible. Any information would be great thanks! :)
Osteoarthritis can cause bone spurs to form. Bone spurs a bony growth formed on normal bone and usually forms when the body tries to repair itself by building extra bone. Hence, sometimes, as we age and the slippery tissue in between our joint breaks down and wears away, bone spurs may form in along the edges of the joints.

What is the bone called that is located above your heel and behing your akilies?

---

I fractured this bone in my foot that the dr. says not everyone has. I checked the internet and i can not find the bone that was shown in my x ray!
I know all the bones and you have me stumped... you might be confused... The lower leg has the tibia and fibula; the foot has the calcaneus, cuboid, navicular, cuneiforms (3), talus, and the metatarsals. Maybe it was part of one of these bones? The little bumps and things on the bones have names too - maybe it was a tubercle?  (+ info)

What is the most common way to break a bone?

---

I'm writing a story and I'm trying to write a scene where the character gets in a fight and breaks a bone. Having never actually broken a bone, I turn to you guys for help.

If someone got into a fight, how hard would they have to be hit to break a bone? What bone would be broken? (I'm thinking more of arm or collar bone or something, rather than just nose.) If they put it up and someone hit their arm, could it break it? Or would it have to be hit against something harder?
Usually it's a 'slip & fall' that breaks a bone.
It would have to be a mighty punch to break someones bone (and not your own as well).
If they were pushed and fell awkardly, that's another story.  (+ info)
