Synthetic bone takes a little longer to consolidate , said Dr. Constantine Simos , an instructor and practitioner in the Oral and Maxillofacial Surgery Department of Tufts University School of Dental Medicine
.The advantage is that the patient avoids a donor site and the procedure can be accomplished more quickly..
That's one reason bone allografts ( typically cortical or trabecular ) are popular alternatives.Allografts are osteo-inductive and osteo-conductive.They do not have the osteogenic properties that allow bone to form quickly and under conditions in which significant bone augmentation or repair is needed.3.
said harvesting natural bone from intraoral sites can be done in the office ; in most cases , so can harvesting from the tibia.But taking bone from the hip will most likely be performed in a hospital operating room or outpatient surgery center so you have to factor in additional costs as well as the disadvantage of having to recover from surgery at an extra site.
Alloplastic bone grafting materials come in a wide array of formulations.These include non-resorbable and resorbable hydroxyapatite versions ; polymer , hard-tissue replacement materials ; and glass ceramics.
added , however , that autogenous bone is more predictable , and that a combination of autogenous bone and synthetic bone is a popular route to take.Natural bone is more predictable , he
For example , suppose a doctor is doing a sinus lift.If you use real bone , you can be certain that , within about four to six months , you'll be able to place implants.With synthetic , you have to wait about eight to 12 months and then evaluate it with x-rays.It's not as predictable.
Also , it's never clear cut that it's just natural bone or just synthetic.
said the initial procedure can be readily learned by GPs and then offered to their patients.For general practitioners who are doing extractions , ridge preservation is something that they could pick up through continuing education and something they could offer to the patient.If the patient fractures a tooth or if a tooth cannot be restored and the patient plans on an implant in the future , ridge preservation can certainly be something important that they can offer the patient.
And , even if they are not going to do it , they can make the patient aware of it..
Ridge preservation materials
said synthetic bone is usually the top choice with ridge preservation.Ridge preservation implies preserving or maintaining the width and the height the way it would have been if the tooth was there , he
said.Alternatively , once the tooth is removed , the bone will slowly resorb and you will lose the height and the width that you had when the tooth was there.Ridge preservation is done right when the tooth is extracted.
Again , similar discussion takes place as to which material to use , although with ridge preservation , the amount that you need to graft is so minute , so small that that's almost always done with synthetic.It would be too small of a gain to do something like graft natural bone.Although some people maybe just take it from another part of the jaw.
said alveolar distraction ( also referred to as distraction osteogenesis ) is a new and effective development. ( He
also believes bone morphogenic proteins ( BMPs ) will be effective one day. ).
Distraction osteogenesis is a general term ; basically , it means regenerating bone by the process of distracting or elongating it.Osteogenesis specifically applies to bone.A more correct term would be distraction histogenesis , which applies when one is trying to regenerate bone and soft tissue.
Alveolar distraction is hot , Dr. Simos
said.In the last four to five years , more devices have been manufactured to accomplish this regeneration , and more implant surgeons are making use of this process.
One of the things about distraction is that it actually uses the existing bone and soft tissue.It sort of elongates them to get the required height and width.It's predictable because you're using the patient's own tissue , and it's already there..
Another significant advancement is bone morphogenic proteins ( BMPs ) , Dr. Simos
said.They are the future of bone regeneration and these kinds of procedures.BMPs still are in clinical trials , but they are going to play a significant role in the near future.
BMPs are basically proteins found naturally in the body.They stimulate stem cells or pre-cursor cells to become osteoblasts or cells that make bone.They take cells , which aren't really quite anything yet , and make them into cells that produce bone.
