摘要
目的评价磨牙大面积牙体缺损采用纤维桩及全瓷冠修复的短期临床效果。方法28例患者,共33颗磨牙残冠根采用纤维桩及全瓷冠修复。于修复体黏固后1周、1个月及6～24个月复查,评价修复体完整性,边缘适合度,牙周组织健康状况及根尖周健康状况。结果93.9%的修复体保持完整。有2颗修复体发生崩瓷或折裂,为咬硬物所致。所有修复体边缘适合性良好,色泽稳定,牙龈状况良好。纤维桩及树脂核无松动、折裂、缝隙等。X线片未见根尖异常,未见根折或桩折。结论在严格掌握适应证的条件下,将纤维桩及全瓷冠用于磨牙残根残冠修复能够取得良好的近期临床效果。
Objective To evaluate the treatment outcome of fiber-reinforced composite posts and all ceramic crown in restoring extensively damaged molar. Methods A total of 33 molars of 28 patients were included. After complete root canal therapy, the teeth were restored with fiber-reinforced composite posts and all-ceramic crowns. Patients were followed up for 1 - 24 months. Clinical examinations and radiograph were taken to evaluate the treatment outcome. Results 93.9% restorations were found to be intact. Little wane was found in one In-ceram crown caused by hard food biting. One IPS E.max press crown broke for hard biting. One tooth suffered from gingivitis, and was cured by polishing. No loosening, fracture and gap existed among fiber post, composite resin core, dentine and crown. No dislodgment or fracture of posts or roots were observed in all restorations. Conclusions The favorable results after 1 - 24 months of clinical service indicate that fiber-reinforced composite post-and-core system and all-ceramic crown are reliable and ideal materials in the restorations of molar residual root and crown.
