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.

I loved my experience at Dr. Lopez's office. 20 years ago I had several unsightly metal fillings put in my mouth. Also, I've worn my teeth down by grinding considerably over the years. As I grew older, my teeth did not look good to me when I smiled. In July of 2015, I wanted to have all of the metal fillings in my mouth removed, and one of the fillings in particular had already cracked the tooth that it filled. Initially, I was very nervous, but Dr. Lopez and his staff completely put me at ease from the time I walked in the door. The way he rebuilt the grinding damage on my back teeth is remarkable. He is not only a great dentist but a gifted architect and engineer at the same time. I didn't even feel the numbing shots at all, and I actually fell asleep in the chair during the procedure thanks to Dr. Lopez's relaxing demeanor and the calming music in the room. To my wife, I affectionately refer to him as Dr. Lopezzzzzz, now, since I did fall asleep. I would recommend Dr. Lopez to even my closest family. Thank you, again, Dr. Lopez.

I went to Dr. Lopez to get veneers on eight teeth (upper, front). From my initial consultation to getting my temporary veneers put in today, I have been consistently impressed by his practice. The entire staff operate as a single, professional team. Extremely courteous, knowledgable, and accommodating, they do everything they can to help patients feel both comfortable and fully informed of everything that goes on during their visit.

My process with the veneers thus far has been extremely smooth and easy. Despite what you may read on the Internet from other people who have gotten veneers elsewhere, Dr. Lopez goes through great measures to ensure that your experience is pain and worry free. He is truly a master at his craft, and his vast experience in the dental profession (equally reflected in his accolades) definitely shows.

I have a check-up for the temporary veneers in the next couple of weeks, and the permanent veneers will arrive shortly thereafter. I have full confidence that the rest of this process will go just as well as it has so far, especially after my visit today. Highly recommend this office for your dental needs. 5/5 stars.

I have never liked going to the dentist because of painful past experiences. Shots, rough cleanings, etc. On my first visit, I had a cleaning . There was no pain. I was impressed. And a recent event that required shots, and extractions had me concerned about pain, but Dr. Lopez reassured me not to worry. As he began the shots,NO PAIN AT ALL!!! I was more than impressed! I knew I had found my dentist. Dr. Lopez and his staff are kind, gentle, professional, and the atmosphere is very relaxed and pleasant! I am very pleased, and highly recommend him!!!
