摘　　要：目的:比较3种序列咬合纸选磨调[牙合]方式对单颗磨牙种植修复延迟咬合特征的影响。方法:选择32例患者32颗第一磨牙种植修复体,按随机数字表法分为A组(12例)、B组(10例)和C组(10例),分别采用(100+40)、(100+50+30)、(100+40+20)μm序列咬合纸调[牙合],TeeTester数字化咬合分析系统检测修复当天,修复后3、6个月修复体与邻牙的咬合延迟时间及[牙合]力百分率比值,同期记录随访期间各组需再次调[牙合]的病例数。采用SPSS 25.0软件包对数据进行统计学分析。结果:修复当天各组咬合延迟时间差异均有统计学意义(P<0.05),修复后3、6个月,C组仍小于A组和B组(P<0.05);随访期间各组时间均有缩短趋势(P<0.05),但仍存在咬合延迟。与B组及C组相比,A组在修复各时间点的[牙合]力百分率比值均较小(P<0.05);随访期间各组比值呈增大趋势(P<0.05),其中C组升高幅度最大(P<0.001)。A组需再次调[牙合]病例数较少,C组最多(P<0.05)。各组种植修复体与邻牙的咬合延迟时间与[牙合]力百分率差值存在正相关性(P<0.001)。结论:(100+40)μm序列组咬合稳定性高,具备更强的临床适用性。序列选磨调[牙合]方式实现的咬合接触间隙越小者,咬合特征变化可能越大,临床上需密切随访。PURPOSE:To compare the effects of three occlusal adjustment methods in different sequences by articulating paper on the delayed occlusal characteristics of single molars.METHODS:Thirty-two implants of first molars were divided into group A(n=12),group B(n=12)and group C(n=12)by sequential adjustment according to random number means,and(100+40),(100+50+30)and(100+40+20)μm sequence occlusal papers were used for occlusal adjustment,respectively.TeeTester was used to measure the delay time and force ratio between prosthesis and adjacent teeth at restoration day,3 and 6 months after restoration,and to record the number of cases readjusting in each group during follow-up.SPSS 25.0 software package was used for data analysis.RESULTS:There were significant differences in delay time between groups at restoration day(P<0.05),and 3 and 6 months after restoration,delay time of group C was still smaller than that of group A and B(P<0.05).During follow-up,the time of each group showed a trend of shortening(P<0.05),but there was still delayed occlusion.Compared with group B and C,the force ratio in group A was lower at each time(P<0.05).The ratio of each group showed an increasing trend during follow-up(P<0.05),and group C showed the largest increase(P<0.001).The number of cases readjusting was relatively small in group A,and the most was in group C(P<0.05).There was positive correlation between delay time and force difference of prosthesis and adjacent teeth(P<0.001).CONCLUSIONS:The(100+40)μm sequence group had higher occlusal stability and better clinical applicability.The smaller the occlusal contact space realized by the sequential method,the greater the change might be,which requires close follow-up in clinical practice.
