文题释义: 
超瓷材/复合纤维:
是一种新型的非金属类固定修复材料,含有陶瓷填料和树脂基质,两种材料的联合使用,有效改善了瓷材料脆、硬的缺陷,具有良好的硬度和机械强度,在修复治疗之后,不会导致过度磨损对颌牙情况的出现,不破坏正常恒牙的建立,因此,不会对儿童及青少年的正常生长发育及口颌系统健康状态等产生不利的影响。
恒牙牙体缺损修复材料:当前临床上应用比较广泛的嵌体种类主要有——合金嵌体、瓷嵌体及聚合瓷(超瓷)嵌体3大类。其中,合金嵌体有很多种,包括非贵金属及贵金属成分,其中金合金嵌体是尤为理想的一种材质,其生物性、抗压强度及硬度能与天然牙达到理想的匹配,缺点就是有色金属;铸瓷嵌体强度不及金属嵌体,临床反应有崩裂现象,目前也有尝试氧化锆嵌体,其强度较铸瓷高,但硬度较天然牙高,因此难以避免会造成对天然牙磨损的现象,而瓷嵌体最大的优势就是颜色逼真。

背景:超瓷材/复合纤维是一种新型的非金属类固定修复材料,具有良好的硬度和强度,但目前关于超瓷材/复合纤维修复年轻恒牙牙体缺损的研究相对较少。
目的:观察超瓷材/复合纤维修复年轻恒牙牙体缺损的临床效果。
方法:纳入60例年轻恒牙牙体缺损患者,其中男27例,女33例,年龄10-17岁,均接受超瓷材/复合纤维修复治疗。修复后随访36个月,检测患者牙周碱性磷酸酶水平、牙周探诊深度、龈沟出血指数、牙齿松动度、菌斑指数、龈沟液量和天冬氨酸转氨酶水平,以及观察修复体完整性、边缘适合性及颜色匹配情况。
结果与结论:修复后36个月,患者牙周碱性磷酸酶水平与修复前比较差异无显著性意义(P > 0.05),牙周探诊深度、龈沟出血指数、牙齿松动度、菌斑指数、龈沟液量和天冬氨酸转氨酶水平均较修复前明显下降(P < 0.05);2例修复体不完整,6例修复体颜色不匹配,2例修复体边缘不密合。结果表明,超瓷材/复合纤维修复年轻恒牙牙体缺损,可维持良好的牙周健康状态,具有良好的组织相容性。

Abstract:

BACKGROUND: Targis/composite fiber is a new type of non-metallic repair material that has good hardness and strength, but it is rarely reported on its application in the repair of young permanent tooth defects.

OBJECTIVE: To investigate the clinical effect of Targis/composite fiber in repairing young permanent tooth defects.
METHODS: Sixty cases of young permanent teeth defects 10-17 years of age were enrolled, including 27 males and 33 females. All cases were subjected to Targis/composite fiber repairing. After 36 months of follow-up, alkaline phosphatase level, probing depth, gingival sulcus bleeding index, tooth mobility, plaque index, gingival crevicular fluid volume and aspartate aminotransferase level in patients were detected; the integrity and edge of dental prosthesis and the color matching.

RESULTS AND CONCLUSION: After 36 months, the alkaline phosphatase level in the patients had no significant changes (P > 0.05), but the probing depth, gingival sulcus bleeding index, tooth mobility, plaque index, gingival crevicular fluid volume and aspartate aminotransferase level were decreased significantly compared with those before repair (P < 0.05). Additionally, there were two cases of incomplete dental prosthesis, six of color mismatching, and two of unsealed prosthesis edge. These findings indicate that the Targis/composite fiber for repairing young permanent tooth defects has good histocompatibility maintains periodontal health in good condition, is a kind of ideal repair materials.
