自體移植 牙齒也可種回去 【施靜茹】因齒顎矯正拔掉臼齒，或用不到的智齒，過去可能拔掉不用，台北醫學大學日前成立台灣首家保存恆牙的牙齒銀行，標榜以後蛀牙能做為自體牙齒移植。 台北醫學大學牙醫學系主任李勝揚指出，自體牙齒移植和牙齒再植，就是把口內一顆健康牙齒拔起來後，移植到另一顆缺齒位置，在台灣臨床發展十多年，成功率可達九成。 適合做自體牙齒移植的牙齒，包括智齒、齒顎矯正拔掉的臼齒、牙齒萌發位置或角度異常的多生牙、阻生牙，都能保存。 李勝揚說，日本厚生省與齒科醫師19年前就提出「8020」運動，希望日本國民到80歲，仍擁有20顆自己的牙齒，所以這次北醫與日本廣島大學牙齒銀行合作，使用專利程式降溫儀，避免因冰晶形成造成細胞受損。 至於保存恆牙能否萃取幹細胞做為保存？李勝揚說，乳牙能取得牙髓體積約0.2cc，恆牙約0.4cc，再從中分離培養幹細胞保存，待日後幹細胞技術達純熟境界，就能使用。 台北榮民總醫院牙科部主任高壽延說，過去治病人牙齒時，如果病人剛好第一、二大臼齒蛀牙，而且第三大臼齒（智齒）還在，就可以用智齒補臼齒蛀牙。 不過，高壽延強調，第一、二大臼齒如蛀得早，後面牙齒可能向前推，使蛀牙牙槽空間縮小，再加上有人智齒牙根呈爪狀，相對較大，必須修磨才能移植蛀牙區，但可能使牙周細胞受損，造成移植效果變差。 2008-09-30 Autologous transplantation can be kind of back teeth Shi Jing-Ru】 【because of Orthodontists molar pulled, or less than the wisdom teeth, in the past may not have pulled out, Taipei Medical University recently set up to preserve Taiwan's first permanent teeth Bank, tooth decay can do for itself after autologous transplantation teeth . Taipei Medical University dental Head of the Department of Li Yang pointed out that the autologous transplantation of teeth and tooth replantation, the mouth is a healthy tooth pulled up, transplanted to another location of the missing tooth in Taiwan for more than a decade of clinical development, the success rate is Up to 90. Suitable for autologous transplantation teeth teeth, including wisdom teeth, pulled out of Orthodontists the molar teeth or the location of the germination point of view of the abnormal teeth, impacted teeth can be preserved. Li Yang said that the Japanese Ministry of Health and Welfare and dental doctors 19 years ago on "8020" campaign hope that the Japanese people to the 80-year-old, still has 20 of his teeth, so the Taipei Medical University and Hiroshima, Japan Bank teeth, the use of patented cooling program Miriam, to avoid the formation of ice crystals cause damage to cells. As for the preservation of permanent teeth can extract stem cells for preservation? Li Yang said that the deciduous dental pulp can be made about the size 0.2cc, permanent teeth about 0.4cc, and then separated from stem cells to preserve culture, stem cell technology in the future to be reached proficient level, you can use. Taipei Veterans General Hospital Department of Dentistry, said Yan, director of Igor, who in the past dental treatment, if the patient is just the first and second molar tooth decay, and the third molars (wisdom teeth) also can fill with wisdom molar tooth decay . However, the extension of Igor stressed that the first and second molars as early borers, the back teeth may be pushed forward so that the alveolar space to reduce tooth decay, plus some wisdom teeth were root-like claws, relatively large, the mill would have to be transplanted District tooth decay, periodontal cells could cause damage, resulting in the deterioration effect of transplantation. 2008-09-30 View more information, see the World Journal reported that e-ePaper
