摘　　要：目的:评价石英纤维桩联合氧化锆全瓷冠在磨牙大面积缺损修复治疗中的短期临床效果。方法:对28例患者32颗已完善的根管治疗的磨牙残根、残冠,采用石英纤维桩联合氧化锆全瓷冠进行修复。修复后1、6、12个月随访检查,包括修复体完整性、边缘适合性、解剖外形、颜色及牙龈。结果:修复体的完整性好(93.75%),有2例因咬过硬食物崩瓷,边缘适合性及解剖外形良好,修复体颜色与邻牙协调一致(84.37%),纤维桩核及冠均无松动、脱落,X线牙片示纤维桩与根管壁密贴,未见折裂等。结论:石英纤维桩联合氧化锆全瓷冠在磨牙大面积缺损修复治疗中可取得良好的近期临床效果。Objective To evaluate the clinical effect of quartz fiber post and zirconia all-ceramic crowns in restoring extensively damaged molar.Methods A total of 32 molars of 28 patients were included.After complete root canal therapy,the teeth were restored with quartz fiber posts and zirconia all-ceramic crowns.Follow-up survey were conducted 1month,6 months and 12 months later,including the intactness,marginal adaptation,anatomical contour and color of prostheses and gingival health.Results 93.75% of prostheses were found to be intact;little wane was found in two all-ceramic crowns due to hard food biting.Marginal adaptation and anatomical contour was good,color of prostheses in harmony with adjacent teeth（84.37%）.No loosening or exfoliation was found among quartz fiber posts and composite resin core.Roentgen diagnosis revealed posts＇ adaptation to root canal without fracture of posts and cores in any prostheses.Conclusion Quartz fiber posts and zirconia all-ceramic crowns are reliable and ideal materials in the restoration of extensively damaged molar.
