Pelas listas de discussão da ESCO(Eletronic Study Club for Orthodontics), corre a discussão sobre a redução do tempo nos tratamentos ortodônticos, a OrthoAccel's proprietary technology promete uma redução do tempo requerido de tratamento com o aprelho Celerect - utilizando forças cíclicas para mover o dente através do osso de forma mais rápida através de acelerada remodelação óssea. O produto é um dispositivo removível similar a um retentor com fio ortodôntico ou protetor bucal e já foi validado em modelos animais. Supõem-se que os aparelho aplique forças intermitentes a baixa frequencia no arco(1-60Hz) de forma pulsátil e vibratória por 20 minutos ao dia sem dor ou desconforto. O paciente ativa o aparelho uma vez ao dia e o mesmo se adapta a todos os sistemas de bráquetes, podendo tratar todas as maloclusões ou servir como um verdadeiro complemento. Os testes em humanos iniciam no próxima primavera. Vamos ver .




Now, there may be some theory here. I'm not sure what it is, but there may be one. UIC people, is there something from the labs there that we should know about?

Let's analyze the claim that "its device cuts in half the treatment time required for braces..." They likely have absolutely no data to support this. They have done no work at all in humans ("The company expects to begin human clinical studies at the University of Texas Dental Branch at Houston in late spring 2008.") They may have some animal work (two brackets a certain distance apart, connect together with NiTi spring, in animal with Celerect the teeth move together in x days, instead of 2x days in the control animal). As any orthodontist knows, the time two teeth take to move across an edentulous space has little to do with how long someone has to wear braces.

If you can't even get a kid to brush his teeth twice a day (takes maybe 5 minutes) how many do you think will actually wear something, undoubtedly an uncomfortable something, for even 20 minutes per day?

20+ years ago, when we were in our ortho program, there was some interest in using electric fields to speed up bone healing and turnover (Paul Broadwater could weigh in on this topic). The obvious application of this would initially be in fracture healing, particularly in leg bones. I've seen a lot of my patients come in with fractured bones, and not one of them has ever had any sort of plug-in or battery-operated device to help the bone to heal. This indicates to me that the technique either did not work or caused some sort of other problem.

Anyone else have contributions on this topic? Anyone else want to start our own startup? According to OrthoAccel, it's a "$10. Billion dollar market" for this device.
