To evaluate the influence of soft tissue aesthetic outcomes following application of adhensive fixed partial denture and implant supported temporary restoration in maxillary single tooth implant procedure. Discuss the feasibility and details of the shaping the soft tissue by combine adhensive fixed partial denture and implant-supported temporary restoration.
The study included 29 patients(Male: 17, Female: 12) with hopeless maxillary single tooth from Sept. 2008 to Dec. 2010. All patients received tooth extraction and implant treatment in department of oral implantology, Peking University School and hospital of Stomatology. The adhesive fixed partial denture as a provisional restoration was used to support the soft tissue of the tooth extraction socket after tooth extraction. The average time of patient wearing adhensive fixed partial denture was 3.7 months. The implant supported temporary restoration was delivered to shape the soft tissue after implant placement. The average time of implant supported provisional restoration using was 8.3 months. Soft tissue esthetic condition was evaluated through 4 main index reference pink esthetic score (PES) before tooth extraction and at the time of the final restoration. Clinical observe items also included the survival rate of fixed partial denture and rate of re-adhesive, integrity of temporary restoration and degree of satisfaction of the patients. The control group included 29 cases with removable denture or without temporary restoration. The base line differences between control group and experiment group were not statistically significant.
The survival rate of both the adhensive partial denture and implant-supported provisional restoration was 100%. The re-adhesive rate of adhesive partial denture was 16.2% during follow-up period. The PES at the time of final restoration were significant different between two groups by t test (7.48±0.51 vs. 5.69±0.71, P<0.000 1). Patients were satisfied with the clinical results.
This study indicates that fixed partial restoration and implant-supported provisional restoration could be used to support and to shape the soft tissue contour and to improve the aesthetic effects.
评估在上颌单颗牙种植手术中应用粘结固定局部义齿和种植体支持的临时修复体对软组织美学效果的影响。探讨联合应用粘结固定局部义齿和种植体支持的临时修复体塑造软组织的可行性及具体方法。
本研究纳入了2008年9月至2010年12月期间29例上颌单颗牙无法保留的患者（男性17例，女性12例）。所有患者均在北京大学口腔医学院口腔种植科接受拔牙及种植治疗。拔牙后使用粘结固定局部义齿作为临时修复体来支撑拔牙窝处的软组织。患者佩戴粘结固定局部义齿的平均时间为3.7个月。种植体植入后使用种植体支持的临时修复体来塑造软组织。种植体支持的临时修复体的平均使用时间为8.3个月。通过4项主要指标参考粉色美学评分（PES）在拔牙前及最终修复时评估软组织美学状况。临床观察项目还包括固定局部义齿的存留率、重新粘结率、临时修复体的完整性及患者的满意度。对照组包括29例使用可摘义齿或未进行临时修复的病例。对照组与试验组的基线差异无统计学意义。
粘结局部义齿和种植体支持的临时修复体的存留率均为100%。随访期间粘结局部义齿重新粘结率为16.2%。两组最终修复时的PES经t检验差异有统计学意义（7.48±0.51 vs. 5.69±0.71，P<0.000 1）。患者对临床结果满意。
本研究表明，固定局部修复和种植体支持的临时修复可用于支撑和塑造软组织轮廓并改善美学效果。
