【摘要】 目的:探讨牙周病伴牙列缺损的患者,经套筒冠义齿修复后对牙周组织的影响。方法:选择18例牙周病伴游离端缺损欲行套筒冠修复的患者,修复前对患者基牙进行完善的牙周序列治疗和根管治疗。病情稳定后进行套筒冠义齿修复,随机分为洁治组和非洁治组。并对洁治组患者的牙周进行定期牙周序列治疗。记录下修复前,修复后1个月,修复后3个月,修复后6个月四个时段基牙的菌斑指数(PLI),牙龈指数(GI),牙龈出血指数(BOP),探诊深度(PD),牙齿松动度,并采用产黑菌及具核梭杆菌的选择性培养基对龈下菌斑标本进行分离培养,并进行对照比较。结果:经套筒冠修复后,牙齿松动度逐渐变小,与修复前相比差异有统计学意义(P<0.05)。套筒冠义齿修复后洁治组四时段,菌斑指数、牙龈指数、探诊出血指数与基线无显著性差异;洁治组四时段之间,以上指数均无显著性差异,牙周袋变浅与基线有显著性差异。套筒冠义齿修复后非洁治组修复后6个月菌斑指数、牙龈指数上升明显,与基线差异有显著性(P<0.05);其余各项差异无显著性。套筒冠义齿修复后洁治组基牙牙周产黑菌与具核梭杆菌的检出率在各时段与基线差异无显著性;基牙各时段之间差异也无显著性。非洁治组套筒冠义齿修复后,产黑菌、具核梭杆菌检出率在修复后3个月上升(P<0.05),6个月后明显上升(P<0.01)。结论:牙周病伴牙列缺损患者经套筒冠义齿修复后,由于通过改变基牙的冠根比例,降低了基牙的松动度,但义齿对细菌的附着并未改善,说明及时进行牙周序列治疗,防止菌斑的再次形成,对提高该义齿的成功率具有重要意义。更多还原

【Abstract】 Objective: To study the influence on periodontal disease with defect of dentition after telescope crown retainer to the abutment periodontium .Methods: 18 cases of periodontal diseases and these complicated with partial edentulism were treated with prosthodontic methods after comprehensive periodontal therapy.Telescope crown was choised after state steady and divided into two groups at random:periodontal therapy group and non-periodontal therapy group. Plaque Index ( PLI) , Gingival Index ( GI) , Probing Depth ( PD) , Sulcus Bleeding Index (SBI),Tooth movability(TM) of both before and following prosthetic restoration of 1,3,6months were recorded. Samples from subgingival pocket were collected,cultured,evaluated and compared between periodontal therapy group and non-periodontal therapy group.Result: Compared to abutment before prosthetic,the teeth movability after telescopic denture treatment got notable decrease(P<0.05). PLI,GI,SDI and the quantity of Bacillus megatherium and F.nucleatum of the periodontal therapy group had not notable change compared with the basic line.(P>0.05). After restorative 3 month, GI,PLI and the positive rate and the quantity of Bacillus megatherium and F.nucleatum of the non-periodontal therapy group showed significant different with the periodontal therapy group(P<0.05).6 month later,the upwards index showed extreme different the both group(P<0.01).Conclusion: Periodontal diseases and these complicated with partial edentulism were treated with telescope crown retainer to decrease the tooth movability.But periodontal plague attachment was not under control effective. So the periodontal therapy has important sense to raise the achievement ratio of prosthetic after telescopic crown retainer by preventing the relapse of periodontal plague attachment.更多还原
