文题释义:
光固化复合树脂:
是一种重要的填充材料,由树脂基质和一些石英玻璃、陶瓷、二氧化硅等无机填料组成,还加入了一些能对X射线起到阻射作用的钡、镧等材料,便于牙齿修复后的检查;具有色泽美观、易于恢复自然牙外形、稳定耐磨等特点,特别适用于修复前牙牙冠缺损。
新型光固化复合树脂:因为一些无机添料的添加,显著增强了硬度、耐磨性和耐折性,从而可以用于修复咀嚼力比较大的后牙。对于美观要求比较高或后牙缺损不大的患者来说,是一种十分理想的补牙材料。临床利用光固化复合树脂对前牙牙冠缺损患者进行修复治疗,可在保留残存牙冠的前提条件下,对患者自然牙的特点和外观形状等予以恢复。而且,光固化复合树脂可以和患者牙体直接爱你发生强力的粘结,修复结束之后可以长期保持较好的抗压性和耐磨性,从而有效提高了修复效果以及充填材料使用寿命长。

背景:光固化复合树脂性能好,色泽美观持久,具有一定的的抗压强度,因此被广泛应用于口腔修复,但目前关于其修复成人正畸牙冠缺损的报道相对较少。
目的:探讨光固化复合树脂修复成人正畸牙冠缺损的可行性。
方法:纳入300例成人正畸牙冠缺损患者,其中男160例,女140例,年龄16-41岁,均实施光固化复合树脂充填修复。修复结束后随访36个月,了解修复大体外观效果、临床修复效果及不良反应发生情况。
结果与结论:①经修复,患者咬颌关系正常,光固化树脂冠十分稳固,外观与邻牙对侧同名牙对称,无叩痛,X射线片检查根尖无阴影;②随访36个月,300例患者中,修复成功268例,其余32例出现脱落,修复成功率为89.33%;300例患者中,对修复效果表示满意的有271例,满意率为90.33%,300例患者均未出现严重不良反应;③结果表明:光固化复合树脂修复成人正畸牙冠缺损的成功率及患者满意率高,且无严重不良反应。

Abstract:

BACKGROUND: Because of good performance, beautiful and permanent color, and certain compressive strength, light-cured composite resin has been widely used in dental restoration. But there are less reports about its usage in adult crown restoration during orthodontic treatment.

OBJECTIVE: To explore the feasibility of light-cured composite resin in the adult crown restoration during orthodontic treatment.
METHODS: 300 adult cases of crown defects scheduled for orthodontic treatment were enrolled, including 160 males and 140 females, aged from 16 to 41 years. All the crown defects were filled with light-cured composite resins. After 36-month follow-up, the gross appearances of repaired teeth, repairing effect and adverse reactions were statistically recorded and analyzed.

RESULTS AND CONCLUSION: After restoration, patients exhibited normal occlusion, and the filled crowns were fixed stably and firmly whose appearance was symmetric with that of the contralateral isonym tooth of the adjacent tooth. In addition, patients complained of no percussion pain, and no apical shade was shown by X-ray examination. At the end of the follow-up, crown restoration was successful in 268 of 300 cases, with a success rate of 89.33%, and the filled crowns fell out in the other 32 cases; 271 of 300 cases were satisfied with the repairing effect, and the satisfaction rate was 90.33%. Besides, there were no serious adverse reactions in all the patients. These results show that light-cured composite resin for adult crown restoration during orthodontic treatment obtains a higher repair success rate and satisfaction rate, with no serious adverse reactions.
