Platelet Rich Plasma
Oral Surgery Norwood, MA | Mansfield, MA
Platelet Rich Plasma (PRP) is exactly what its name suggests. The substance is a by-product of blood (plasma) that is rich in platelets. Until now, its use has been confined to the hospital setting. This was due mainly to the cost of separating the platelets from the blood (thousands) and a large amount of blood needed (one unit) to produce a suitable quantity of platelets. New technology permits Dr. Turesky to harvest and produce a sufficient quantity of platelets from only 20-40 cc of blood drawn from patients in his office.
Why All The Excitement About PRP?
PRP permits the body to take advantage of the normal healing pathways at a greatly accelerated rate. During the healing process, the body rushes many cells and cell types to the wound in order to initiate the healing process. One of those cell types is platelets. Platelets perform many functions, including the formation of a blood clot and the release of growth factors (GF) into the wound.
These GF (platelet-derived growth factors PGDF, transforming growth factor-beta TGF, and insulin-like growth factor ILGF) function to assist the body in repairing itself by stimulating stem cells to regenerate new tissue.
The more growth factors released and sequestered into the wound, the more stem cells stimulated to produce new host tissue. Thus, one can easily see that PRP permits the body to heal faster and more efficiently.
A subfamily of TGF is a bone morphogenic protein (BMP). BMP has been shown to induce the formation of new bone in research studies in animals and humans. This is of great significance to the surgeon who places dental implants. By adding PRP, and thus BMP, to the implant site with bone substitute particles, the implant surgeon can now grow bone more predictably and faster than ever before.
PRP Has Many Clinical Applications:
- Bone grafting for dental implants. This includes only and inlay grafts (ridge split grafts), sinus lift procedures, ridge augmentation procedures, and closure of cleft, lip, and palate defects.
- Repair of bone defects created by removal of teeth or small cysts.
- Repair of fistulas between the sinus cavity and mouth.
PRP Has Many Advantages:
- Safety: PRP is a by-product of the patient’s own blood; therefore, disease transmission is not an issue.
- Convenience: PRP can be easily generated in the doctor’s office while the patient is undergoing an outpatient surgical procedure, such as placement of dental implants.
- Faster healing: The supersaturation of the wound with PRP, and thus growth factors, produces an increase of tissue synthesis and thus faster tissue regeneration.
- Cost-effectiveness: Since PRP harvesting is done with only 55 cc of blood in the doctor’s office, the patient need not incur the expense of the harvesting procedure in the hospital or at the blood bank.
- Ease of use: PRP is easy to handle and actually improves the ease of application of bone substitute materials and bone grafting products by making them more gel-like.
Frequently Asked Questions About PRP:
Is PRP safe?
Yes. During the outpatient surgical procedure, a small amount of your own blood is drawn out via the IV. This blood is then placed in the PRP centrifuge machine and spun down. In less than fifteen minutes, the PRP is formed and ready to use.
Should PRP be used in all bone-grafting cases?
Not always. In some cases, there is no need for PRP. However, in many cases, the application of PRP to the graft will increase the final amount of bone present in addition to making the wound heal faster and more efficiently.
Will my insurance cover the costs?
Unfortunately not. The cost of the PRP application is paid by the patient.
Can PRP be used alone to stimulate bone formation?
No. PRP must be mixed with either the patient’s own bone, cadaver bone, or a synthetic bone product.
Are there any contraindications to PRP?
Very few. Obviously, patients with bleeding disorders or hematological diseases do not qualify for this in-office procedure. Dr. Turesky will help you to determine if PRP is right for you.
