【摘要】：目的:拍攝口腔頜面部錐形束CT(Cone-beam computed tomography,CBCT),應(yīng)用“彩立方植牙與定位器定制系統(tǒng)”進(jìn)行種植位點(diǎn)的設(shè)計(jì)并制作出數(shù)字化3D打印導(dǎo)板,輔助醫(yī)師在上頜前牙區(qū)進(jìn)行種植體的植入,術(shù)后分析應(yīng)用數(shù)字化3D打印導(dǎo)板在上頜前牙區(qū)進(jìn)行種植手術(shù)的精確度,對(duì)其在上頜前牙區(qū)種植的精度進(jìn)行評(píng)價(jià)。方法:選擇2015年9月-2016年8月,于青島大學(xué)附屬醫(yī)院口腔種植科行種植手術(shù)的40例上頜前牙區(qū)牙列缺損的患者,隨機(jī)分為I、II兩組,每組20例。第Ⅰ組患者術(shù)前取模并灌注石膏模型,制作并佩戴放射導(dǎo)板拍攝CBCT,第Ⅱ組患者常規(guī)拍攝CBCT。患者拍攝CBCT后,將數(shù)據(jù)導(dǎo)入“彩立方植牙與定位器定制系統(tǒng)”,進(jìn)行三維重建,通過測量分析種植區(qū)牙槽骨的形狀、寬度、高度、厚度,在種植區(qū)域設(shè)計(jì)合理的種植體數(shù)量、位置、型號(hào),完成種植位點(diǎn)的設(shè)計(jì)。根據(jù)第Ⅰ組患者的設(shè)計(jì)方案制作數(shù)字化3D打印導(dǎo)板,并將其用于種植手術(shù),第II組患者進(jìn)行常規(guī)種植手術(shù)。術(shù)后兩組患者都拍攝口腔頜面部錐形束CT,應(yīng)用“彩立方植牙與定位器定制系統(tǒng)”將術(shù)前設(shè)計(jì)的種植位點(diǎn)與種植體實(shí)際位點(diǎn)進(jìn)行配準(zhǔn)比較,測量實(shí)際位置與設(shè)計(jì)位置的差異,將所得數(shù)據(jù)進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果:第Ⅰ組患者共植入37枚種植體,第Ⅱ組患者共植入32枚種植體。兩組患者術(shù)后均拍攝CBCT,將所得數(shù)據(jù)導(dǎo)入“彩立方植牙與定位器定制系統(tǒng)”,與術(shù)前設(shè)計(jì)的種植位點(diǎn)圖像做配準(zhǔn),比較并測量種植位點(diǎn)與設(shè)計(jì)位點(diǎn)的偏差,測量偏差為:Ⅰ組頂部(0.64±0.40)mm(0.12~1.62 mm),根尖部(0.72±0.39)mm(0.06~1.59 mm),深度(0.42±0.40)mm(-0.67~1.19 mm)和角度(2.35±1.05)°(0.50~4.03°);Ⅱ組頂部(1.57±0.34)mm(0.90~2.20 mm),根尖部(2.04±0.93)mm(0.78~3.61 mm),深度(0.76±0.64)mm(-0.74~1.64 mm)和角度(6.71±3.63)°(2.13~13.13°)。兩組種植體在頂部、根尖部、角度、深度有統(tǒng)計(jì)學(xué)差異(P0.05)。結(jié)論:1.拍攝CBCT并應(yīng)用“彩立方植牙與定位器定制系統(tǒng)”進(jìn)行種植手術(shù)的術(shù)前設(shè)計(jì),診斷更加明確,可以制定更合理的治療計(jì)劃。2.制作數(shù)字化3D打印導(dǎo)板,利用其輔助種植體的植入,將術(shù)前設(shè)計(jì)準(zhǔn)確轉(zhuǎn)移到手術(shù)操作中,提高種植體植入的精度,具備優(yōu)良的臨床應(yīng)用前景。
[Abstract]:Objective: to photograph CT(Cone-beam computed tomographyct of conical bundle in oral and maxillofacial region, and to design the implant site by using "Cube Color Cube Implant and Locator customization system" and to make the digital 3D printing guide plate, which can assist the physician to implant the implant in the maxillary anterior tooth area. After operation, the accuracy of implant implantation in maxillary anterior teeth with digital 3D printing guide was analyzed and evaluated. Methods: from September 2015 to August 2016, the accuracy of implant in maxillary anterior teeth was evaluated. Forty patients with maxillary anterior dentition defect were randomly divided into two groups: I II group (n = 20). The patients in group 鈪，
