UNAIR NEWS – To deal with problems in dental health, dentistry should always improve and innovate. One of the problems often found is a trauma after tooth extraction. The trauma usually causes inflammation which then causes alveolar bone resorption.

Alveolar bone functions as the buffer for artificial teeth, so when the dimension of alveolar bone reduced, either vertically or horizontally, the stability of retention and comfort of the artificial teeth while for dental implants, its reduction will increase the risk of implant failure risk.

Prof. Dr. Utari Kresnoadi, M.S., drg., Sp.Pros(K), in her inauguration as the professor of Faculty of Dentistry (FKG) Universitas Airlangga on Saturday, December 10. The 455th professor of Universitas Airlangga presented her scientific oration titled “Tissue Engineering in Prosthetic Dentistry.”

”In the case of tooth extraction, inflammation can happen because of the trauma of the extraction and the extraction can cause the ridge becomes narrower and shorter and cause the jaw bone atrophy . If it isn’t treated soon, it will affect the artificial teeth application,” he said.

In presence of the guests in Garuda Mukti Hall, Prof. Utari stated that the success of making artificial teeth is by using retentive artificial teeth, uneasy to fall off and stable when they are used to chew. The point is great comfort. Therefore, the artificial teeth demand good anatomical conditions which support successful artificial teeth and one of them is a prominent ridge. To create a good ridge, tooth extraction should be avoided. It is a prevention of alveolar bone resorption which is caused by tooth extraction.

“So, even the wound from the extraction has already closed, the alveolar bone loss will continue to happen,” she explained.

She also said that the role of dentistry technology development, especially prosthodontics is greatly needed. For her, technological development affects and is closely related with the esthetical need, chewing and utterance. Various dental treatments such as artificial teeth, venner crown, artificial implants and many others are affected by technological advancement.

Some innovations on tooth extraction socket preservation has been made by Department of Prosthodontics FKG UNAIR through research on herbal material with various graft material which can stimulate the tissue. Researches conducted with combination of Aloe vera and Xenograft, purple mangosteen exocarp  and chitosan.

The researches were conducted to get the best development model of tissue engineering technique to repair and prevent the resorption of buffer bone through inflammation prevention caused by the tooth extraction trauma and activation of alveolar bone formation activation.

“The researches were also conducted to improve effectiveness of herbal material and graft or chitosan as an excellent bio-product functions as alternative to diminish alveolar bond ridge resorption. This tissue engineering also provides new theory for active compound product development,” she said. (*)
