随着人们寿命增长,无牙颌人口逐渐增多,保持无牙颌者牙槽骨高度显得更重要。口腔医师制作一种既有组织相容性,又不引起吸收的羟磷灰石牙根复制品代替拔除牙根,在防止牙槽骨进一步吸收方面取得很大成就。本文作者主要观察羟磷灰石牙根复制品植入的位置与成功率关系。材料和方法作者对21名拔除下颌牙齿,并立即戴义齿患者进行了研究。治疗经过:仔细拔除下颌牙齿,尽量不损伤牙槽骨,骨尖磨平,不需邻近软组织瓣覆盖。拔牙后用牙槽尺测量牙槽窝高度,选择合适无菌的羟磷灰石牙报复制品植入,用木锤将牙根复制品牢固固定在牙槽窝内,使它位于牙槽嵴下2mm～3mm,缝合牙龈,将预成义齿立即戴上,进行咬合词整。术后嘱患者
With the increase of people's life expectancy, the population of edentulous jaws gradually increases. It is more important to maintain the height of the alveolar bone of the edentulous. Instead of removing the roots, dentists make a great success in preventing alveolar bone from further absorption by making a hydroxyapatite root replica that is histocompatible and does not cause absorption. The author of this paper mainly observed the location of hydroxyapatite root implants implantation and the success rate. Materials and Methods The authors studied 21 patients who had mandibular teeth removed and were immediately denture. After treatment: careful removal of the mandibular teeth, try not to damage the alveolar bone, the tip grinding, without adjacent soft tissue flap coverage. After tooth extraction with alveolar ruler to measure the height of the socket, select the appropriate sterile hydroxyapatite tooth implants implants, with a wooden hammer will be firmly fixed in the alveolar reproductive root socket, so that it is located in the alveolar ridge 2mm ~ 3mm, suture gums, the pre-denture immediately wear, the word occlusion word.
