| 目的 比较上颌前牙区螺丝固位（SR）和粘接固位（CR）的种植修复效果。方法 选择2015年7月至2016年10月于安徽医科大学附属口腔医院种植科修复的74例上颌前牙区缺牙患者（90颗种植体），根据临床固位方式的不同，将患者分为SR组（51颗）与CR组（39颗）。比较两组修复后第1天和3、6、12个月边缘骨吸收、软组织指标和牙龈位置。结果 与SR组相比，CR组骨吸收量显著减少（F组间=14.644，P<0.05）；改良出血指数（mSBI）显著增加（F组间=7.536，P<0.05）；角化龈宽度（wKM）显著增加（F组间=11.489，P<0.05）；牙龈边缘位置（GL）效果较好（F组间=6.407，P<0.05）；两组改良菌斑指数（MPI）记分的差异无统计学意义（F组间=1.525，P>0.05）。CR组美观满意度较高（t=-3.35，P<0.05）；刷牙出血满意度较低（t=3.022，P>0.05）；总体满意度差异无统计学意义（t=0.971，P>0.05）。结论 在边缘骨吸收、wKM、GL和美观满意度方面，CR效果较好；在mSBI和刷牙出血满意度方面，SR效果较好。CR与SR在上颌前牙区的种植修复效果上各有优劣，需临床进一步研究。 |

| Objective To compare the prosthetic outcomes of screw retained (SR) and cement retain (CR) implant restorations in anterior area of maxilla.Methods This study included 74 patients (90 implants) with teeth loss in maxillary anterior region who received odontoprosthesis in Implantology Department of the College & Hospital of Stomatology, Anhui Medical University from July 2015 to October 2016. Based on clinical retaining modes, these patients were classified into SR group (51 implants) and CR group (39 implants), in whichthe marginal bone loss, soft tissue index and gingival level at D1, M3, M6 and M12, respectivelywere compared after odontoprosthesis.Results Compared with screw retained implant restorations, the outcomes observed in patients receiving cement retained implant restoration proved better. The marginal bone loss was obviously less (inter-group F value=14.644, P<0.05); modified sulcus bleeding index(mSBI) was obviously higher (inter-group F value=7.536, P<0.05); the width of keratinized mucosa (wKM) was obviously greater (inter-group F value=11.489,P<0.05); gingival level performed better(inter-group F value=6.407, P<0.05). Modified plaque index (MPI) demonstrated no statistically significant differences between the two groups (inter-group F value=1.525, P>0.05). The esthetic outcome of CR group was better(t=-3.35, P<0.05); the satisfaction level of bleeding during tooth brushing was lower in CR group (t=3.022,<0.05); there was no significant difference in overall satisfaction (t=0.971, P>0.05).Conclusion The CR group achieve a better effect in marginal bone loss, wKM and esthetics while the SR group achievea better effect in mSBI and gingival bleeding induced by tooth brushing. SR and CR implant restorations in anterior maxilla have their own pros and cons. Further studies are still needed. |
