Bone Grafting

Periodontal disease is the leading cause of bone loss in the oral cavity, though there are others such as ill-fitting dentures and facial trauma.  The bone grafting procedure is an excellent way to replace lost bone tissue and encourage natural bone growth.  Bone grafting is a versatile and predictable procedure which fulfills a wide variety of functions.

A bone graft may be required to create a stable base for dental implant placement, to halt the progression of gum disease or to make the smile appear more aesthetically pleasing.

There are several types of dental bone grafts.  The following are the most common:

  • Autogenous bone graft – In this type of graft the bone is removed from elsewhere in the body and implanted in the mouth.  Common donor sites for bone grafting include the iliac section of the pelvis, the chin and the posterior third molar areas of the jaw.  If large amounts of bone need to be harvested, the hip or the shin bone (tibia) is generally used.

  • Allograft – Synthetic bone (man made) can be created in the laboratory and used in the bone grafting procedure.  Bone can also be obtained from a bone bank (cadaver bone).

  • Xenograft – This is the implantation of bovine (cow) bone.  A xenograft is perfectly safe and has been used successfully for many years.  Ample bone can be obtained and no secondary donor site is necessary.

Reasons for bone grafting

There are a wide variety of reasons why bone grafting may be the best option for restoring the jaw bone.

Dental implants – Implants are the preferred replacement method for missing teeth because they restore full functionality to the mouth; however, implants need to be firmly anchored to the jawbone to be effective.  If the jawbone lacks the necessary quality or quantity of bone, bone grafting can strengthen and thicken the implant site.

Sinus lift – A sinus lift entails elevating the sinus membrane and grafting bone onto the sinus floor so that implants can be securely placed.

Ridge augmentation – Ridges in the bone can occur due to trauma, injury, birth defects or severe periodontal disease.  The bone graft is used to fill in the ridge and make the jawbone a uniform shape.

Nerve repositioning - If the inferior alveolar nerve requires movement to allow for the placement of implants, a bone grafting procedure may be required.  The inferior alveolar nerve allows feeling and sensation in the lower chin and lip.

What does bone grafting treatment involve?

Bone grafting is a fairly simple procedure which may be performed under local anesthetic; however if large amounts of bone area need to be grafted, general anesthetic may be required.

Initially, the grafting material needs to either be harvested or prepared for insertion.  A small incision is made in the gum tissue and then gently separated from the bone.  The bone grafting material is then placed at the affected site.

The bone regeneration process may be aided by:

  • Gum/bone tissue regeneration – A thin barrier (membrane) is placed below the gum line over the grafting material.  This barrier creates enough space for healthy tissue to grow and separates the faster growing gum tissue from the slower growing fibers.  This means that bone cells can migrate to the protected area and grow naturally.

  • Tissue stimulating proteins – Enamel matrix proteins occur during natural tooth development.  Emdogain is a matrix protein product which is usually placed on the affected site before the gum is sutured.  It mediates the formation of accellular cementum on the tooth which provides a foundation to allow periodontal attachment to occur.  Tissue stimulating proteins help to create lost support in areas affected by periodontal defects.

  • Platelet-rich growth factors –A high platelet concentration liquid can be used to create a blood clot at the site of a wound.  It has recently been discovered that PRGF also stimulates bone growth – meaning a denser graft in a shorter time period.

The gum is sutured in place and a follow up appointment will need to be made within 10 days to assess progress.  Bone grafting is a highly successful treatment and a good base for further periodontal restorations.

Testimonials

Dr. Mirkin is a trustworthy dentist with a gentle touch. I went in for a cleaning yesterday and was pleasantly surprised by how thorough she was with my consultation. She noted a few problem areas but was not pushy, which was refreshing. She took a lot of time discussing which teeth were most in need of work, and others that may need work down-the-line. I highly recommend Dr. Mirkin to anyone looking for a caring and professional dentist. Thanks Dr. Mirkin!

Since going back to school I lost my dental insurance. I found Dr. Mirkin through groupon and read great reviews so decided to give her a try. She is a very caring, attentive dentist that truly cares about your overall health as well as your teeth. She spends quality time explaining things and making you feel comfortable. She referred me to the dental choice program which is basically a discount program for those without dental insurance. Her prices are reasonable and her services are great. I recommended her to my boyfriend who started seeing her for dental care and we will not go anywhere else now. Also, Jessica her secretary is very friendly, responds quickly to phone calls and online appointment requests and or messages. She has made dealing with this office smooth and efficient.
