摘要
目的评价多功能转移杆(FMT)作为临时基台在上前牙区单牙常规种植即刻修复病例中对种植体周围软组织形态和外形轮廓维持的临床效果。方法收集2015年1月至2016年6月在中山大学附属口腔医院种植科采用Zimmer种植系统行上颌单颗前牙常规种植联合即刻修复和延期修复的患者共43例,其中实验组(即刻修复)23例、对照组(延期修复)20例,共植入Zimmer TSV种植体43枚。观察期为种植术后至永久冠修复共6个月。实验组分别在术后2周、3个月、6个月及戴牙当天,对照组在戴牙当天拍摄口内数码照片,记录龈乳头指数(PFI)、红色美学指数(PES)和唇侧丰满度(LCS),并对实验组和对照组永久冠戴入时的PFI、PES、LCS记录结果进行比较和评估。评估结果采用SPSS 21.0统计软件进行统计分析。结果实验组与对照组戴牙当天的PFI、PES和LCS之间差异均存在统计学意义(t_(PFI)=-4.242,P_(PFI)<0.001;t_(PES)=-8.508,P_(PES)<0.001;Z_(LCS)=-3.307,P_(LCS)=0.001),在观察期各个时间点,实验组的PFI、PES、LCS评分结果均优于对照组。结论 Zimmer多功能FMT在上颌单颗前牙常规种植即刻修复术后6个月的观察期内对种植体周围软组织的外形轮廓起到了一定的维持和引导软组织生长的作用。
Objective To evaluate the clinical effect of the multi- functional Fixture Mount/ Transfer （FMT） as a temporary abutment in the immediate provisionalization of the peri-implant soft tissue morphology and contour profile. Methods From January 2015 to June 2016, 43 patients who were treated with Zimmer implantation system were enrolled in this study consecutively in the Department of Oral Implantology, Affiliated Stomatological Hospital of Sun Yat-sen University. The experimental （immediate restoration, 23 Cases） and the control groups （delayed restoration, 20 cases） were treated with 43 Zimmer TSV implants in total. An observation period of six months was taken from the surgery to the restoration of permanent crowns. Digital oral photographs were taken so as to evaluate the effect of FMT in terms of the papilla filling index （PFI）, the pink esthetic seore（PES）, and the labial convexity score （LCS）. Specifically, for the experimental group, photographs were taken in two weeks, three and six months after surgery, as well as on the day when the permanent crown was fixed, which was done for the control group. The data were analyzed in statistical software （SPSS 21.0）. Results There were significant differences in PFI, PES and LCS between the experimental and control groups （tPFI = -4.242, PPFI 〈 0.001 ; tees = - 8.508, PPES 〈 0.001 ; ZLCS =-3.307, PLCS = 0.001 ）. The scores of PFI, PES and LCS in the experimental group were higher than those in the control group. Conclusions During the observation period of the six months after the immediate provisionalization of sigle-tooth implants in the anterior maxilla, Zimmer multi-functional Fixture Mount/ Transfer played an evidential role in maintaining contour profile and guiding the growth of soft tissue.
