Clinlical application of zirconium dioxide all-ceramic restoration in improving adult anterior teeth with slight malocclusion

目的运用二氧化锆全瓷修复技术,通过短期治疗,快速改善成人轻度错牙合并达到临床美学修复的效果。方法选取22例不愿或不适合进行长期正畸治疗的个别前牙错牙合成人病例,进行二氧化锆全瓷美学修复。修复后进行疗效评估,随访观察1年。结果修复后19例患者对修复效果满意,牙列恢复整齐美观,与邻牙、对颌牙及患者面部关系协调。结论成人前牙轻度错牙合用全瓷冠进行美学修复过程中,适应证的选择、前牙美学修复前的准备、标准化的基牙预备、过渡性修复体的制作、全瓷材料的选择等均为关键性因素。

Objective To improve adult anterior teeth with slight malocclusion and obtain clinical aesthetical effect by using zirconium dioxide all-ceramic restoration in a short period of treatment. Methods 22 patients with slight malocclusion in anterior teeth,who were unwilling to or unsuitable for orthodontic treatment in a long time,were selected for all-ceramic aesthetical restoration. After treatment,therapeutic effects were evaluated with a follow-up observation in one year. Results 19 patients were satisfied with the orthodontic effects. Their dentitions were tidily and beautifully restored,and had harmonious relationships with adjacent teeth,jaw teeth,and the patients＇ facial appearances. Conclusion The choice of indications,preparation before dental aesthetical restoration,standardized butment preparation,fabrication of transitional restoration,and the selection of all-ceramic materials,are crucial for using allceramic restoration to improve adult anterior teeth with slight malocclusion.
