摘要
【目的】探讨即刻种植倾斜种植体修复牙缺失的疗效。【方法】前瞻性选择2015年1月至2017年1月在本院行单种即刻种植倾斜种植体修复牙缺失的患者18例,以术后6个月为基线,进行4年随访,随访时间点分别为放置即刻(T_(0)),6个月(T_(1))、1年(T_(2))和4年(T_(3));统计种植体成功率,比较不同时刻边缘骨水平(MBLs)、颊黏膜水平(MBMLs)、种植体稳定性系数(ISQ)、红色美学分值(RES)和白色美学分值(WES).【结果】18例患者中,4例无完整随访记录,其中1颗种植体在修复前失败,1例病例双侧第一磨牙缺失,2例失访;其余14例共15个单种植体冠完成4年完整随访记录,且未接受其他治疗。4年随访时种植体成功率93.33%(14/15)。与T_(0)时刻比较,T_(1)、T_(2)、T_(3)时刻MBLs、MBMLs值增加(P<0.05);与T_(1)时刻比较,T_(2)、T_(3)时刻MBMLs值增加(P<0.05);但T_(2)、T_(3)时刻MBLs、MBMLs值比较差异无统计学意义(P>0.05)。与T_(0)时刻比较,T_(1)、T_(2)、T_(3)时刻返中和远端乳头的ISQ值升高(P<0.05),但T_(2),T_(3)时刻近中和远端乳头的ISQ值与T时刻比较差异无统计学意义(P>0.05)。与T_(0)时刻比较,T_(1)、T_(2)、T_(3)时刻RES、WES评分明显增高,其差异具有统计学意义(P<0.05),之后T_(2),T_(3)时刻RES、WES评分变化较小,与T_(1)时刻比较差异无统计学意义(P>0.05)。T_(1)时刻共出现2例种植体维护,包括确定种植体冠、饰面瓷和氧化锆基牙断裂,T_(2),T_(3)时刻无种植体修复问题且螺钉完好无松动,随访4年共发生种植体松动1例、基牙疼痛1例、龈炎1例,经积极治疗均得到显著改善。【结论】倾斜种植体即刻植入修复单个缺失牙成功率较高,且具有较好的美学价值,值得临床推广应用。
【Objective】To investigate the effect of immediate load and tilted implant in the restoration of tooth loss.【Methods】From January 2015 to January 2017,18 patients were prospectively selected.All patients were followed up for 3 years,staring from 6 months after surgery.Various indexes were recorded immediately after load(T_(0)),6-month(T_(1)),1-year(T_(2))and 3-year(T_(3))after treatment.There included marginal bone levels(MBLs),mid-buccal mucosal levels(MBMLs),implant success rate,implant stability quotient(ISQ),prosthodontic maintenance,prosthodontic complications,pink esthetic score(PES),and white esthetic score(WES).Then the aesthetic effect was discussed.【Results】Of the 18 patients,4 cases did not have complete follow-up records(1 implant failed before restoration,1 case had bilateral first molars missing,and 2 cases were lost to follow-up).The remaining 14 cases with a total of 15 single implant crowns finished 4 years follow-up.The success rate of implant was 93.33% during the 3-year follow-up period(14/15).Compared to the data at To,the value of MBLS and MBMLs increased at T_(1),T_(2) and T_(3)(P<0.05);and MBMLs value increased at T_(2) and T_(3)compared to T_(1)(P<0.05),however,the value of MBLS and MBMLs at T_(2) showed no significant difference compare to T_(3)(P>0.05).ISQ values of mesial and distal papilla at T_(1),T_(2)and T_(3)were lower than those at To(P<0.05),while the values at T_(2)and T_(3)had no obvious changes,which showed no significant different from those at T_(1)(P>0.05).Compared to To,the RES and WES scores at T_(1),T_(2),and T_(3)were significantly higher,and the difference was statistically significant(P<O.05).After that,the RES and WES scores at Te and Ts changed slightly,and there were no statistical differences compared to T_(1)(P>0.05).At T_(1),there were some prosthodontic maintenance issues involving the definitive implant crowns whichincluded fracture of veneering ceramic and zirconia abutment as well as acsthetic concerns.At T_(2) and T_(3) therewere no further pros
