Losing Bone Due to Periodontal Disease

By Ava Thomas


Periodontal disease leads to the loss of about 30 million teeth by Americans on an annual basis. Due to plaque fosters bacteria that eat away gums, the hard tissue of the jaws end up being exposed here. As soon as the bone in the jaws decays and recedes then the tooth begins to work loose. In stopping this process, dentists are relying on the effectiveness of a new material known as HTR polymer. When it comes to this, they end up gritting their patients' teeth.

For several periodontists on the East Coast, it has been nine years and they are continuing to pack HTR polymer into the gaps that occur between the teeth and the diseased jaws. When it comes to this polymer, there are tiny porous plastic beads coated with a calcium compound that bolster jaw ridges as denture anchors and prevents jaw deterioration where a tooth has been removed.

According to one New York periodontist all sorts of fillers, human bones, animal bones, and even plaster of Paris have been tried out. From these, none have been working as consistently as this one. According to a company spokesman the new materials manufacturer said that a lot of teeth, even millions of them, can be saved by the product. But some experts in the field are skeptical about HTR, as they were about various ceramics and metal pins that preceded it.

As mentioned by the official of the American Dental Association's council on materials and instruments, no jury will be present here. Today, there has yet to be a material that is able to stimulate bone growth. A recent company backed survey of 64 dentists, periodontists and oral surgeons found that in 647 uses of the material, 634 were considered a success.

In trying to save teeth loosened by periodontal disease, the failures occurred. The Food and Drug Administration approval was received in 1983 but before this happened, HTR was actually used experimentally not only in New York clinics but also in surrounding clinics as well. But since then, the material has achieved a 98 percent success rate in more than 4,000 uses worldwide, the company claims.

The results and the material itself have not been submitted to the dental association, which therefore has no official position. When it comes to the material, the company hopes that it will gain acceptance nationwide. It is negatively charged not to mention biologically compatible, nonreabsorbable, and hydrophilic making it able to take up water. What is being described here is the ideal grafting material, also known as HTR.

He considers HTR as something that works simply yet in a mysterious fashion. In this case, the small granules serve as a sort of scaffolding around which new bone material can collect and grow and so they end up injected in the corroded space around the tooth. The material has a hydrophilic nature and so it attracts wet bone marrow cells and the negative charge holds them there and stimulates growth. It is calcium that is needed so that the material will be able to integrate with the bone.

He was once the head of dental research at a medical school in New York, and no longer willing to stop with teeth. Considering how HTR stands for hard tissue replacement, he says that it should work wherever needed. According to him, a considerable amount of work on the spinal fusion and in the treatment of bone fractures have already been done. When it comes to HTR, as long as it is properly molded it can be used as a complete bone replacement.

  1. Periodontitis is typically a slow moving condition, taking many months or even years to develop. Once the disease develops and is diagnosed, it is never really cured.
