Bone Regeneration New York City


In the past, teeth were often removed without placing a bone graft into the site to preserve the shape of the jaw. Once a tooth is missing, the body no longer needs to maintain the width of the jaw which previously accommodated the tooth.  Therefore, the jawbone shrinks in width and the gum tissue follows. This can lead to a deficient jawbone which is too narrow or short to accommodate an implant.

Now, it is possible to preserve the shape of the jawbone at the time of tooth removal and regenerate bone previously lost from prior extractions through bone regeneration.

Socket preservation is the procedure in which bone grafting is performed during tooth removal. This procedure can result in preservation and augmentation of the bone which surrounds the tooth. Tooth removal must be carried out conservatively to promote fast and pain-free healing. This is best performed using the surgical microscope and microsurgical techniques. The tooth socket is then grafted with a combination of different bone graft materials, each with specific properties, to maximize the amount of bone regeneration. The bone graft is then covered with a type of collagen barrier to contain the graft and separate it from the gum tissue. The gum tissue is then conservatively advanced to reduce the exposure of the graft to the oral environment. Socket preservation usually takes about 1.5-2 hrs to complete. It is generally associated with little discomfort and no swelling. The greatest inconvenience after the procedure is the patient needs to chew softer foods on the opposite side of the mouth for 2-3 weeks. Four months after the procedure the patient is ready for implant placement.

If New York City patients have already lost bone structure from previously removed teeth and requires regeneration prior to implants, the procedure is very different. As an analogy, pretend the wood floor (bone) under a carpet (gum tissue) has a large hole. The carpet is now displaced into the wood floor. The furniture in the room (pressure from other forces; lips, cheeks, eating) also resides over the hole and places pressure in that spot. In order to restore the hole, the wood floor would need rigid struts to bridge the gap in the floor. A non-rigid material would not be able to withstand the pressure from the carpet and furniture and would collapse. This is often the situation with bone regeneration for implants (guided bone regeneration- GBR).

When bone is lost after tooth removal, this is analogous to the hole in the wood floor. To regenerate the bone, materials are used to maintain the desired shape of the bone under the gums, and a bone graft is placed within that shape. The shape can best be maintained using rigid materials/barriers that are non-resorbable. Non-resorbable materials mean that they are not absorbed by the body and will need to be removed during a secondary procedure. Resorbable materials are used when the amount of bone missing is minimal (a very small hole in the floor). Over time, resorbable materials become compressed from the pressure of the gum tissue, lips, etc, and the desired result is not obtained.

Most practitioners are not comfortable using rigid materials. This is a very technique-sensitive procedure which requires much training, skill and time to perform without complications. Practitioners are also concerned that using non-resorbable materials is more invasive for New York City patients because it is a two-step procedure.

Servicing the New York City area, periodontist Dr. Kissel has a method to use these materials with little complications and resulting in excellent bone regeneration. He also uses resorbable materials but only when bone loss is minimal, rigid materials are often the best way to completely restore a bone deficiency.
