数字化口腔修复（23）--激光脱敏后的CAD／CAM全瓷冠修复（附病例报告）

目的：观察二极管激光活髓牙脱敏后的CAD／CAM全瓷冠修复效果。方法：对1例13-23／33-43活髓牙烤瓷联冠修复患者，伴有冷热刺激敏感，牙龈萎缩，边缘不密合及颜色不协调，应用CEREC?椅旁CAD／CAM全瓷冠修复，二极管激光辅助活髓牙牙本质脱敏。3个月后采用改良USPHS标准对其临床疗效进行评价。结果：椅旁CAD／CAM二矽酸锂玻璃陶瓷全冠修复体外形颜色美观，边缘密合，粘接、固位良好，冷热刺激过敏症状消除。牙龈健康，形态正常及探诊无出血。结论：半导体激光可以有效减轻和消除牙本质过敏症状。

Digital restorative dentistry and prosthodontics(23)---The restoration of CAD/CAM all-ceramic crown after using dehypersensitivity of diode laser (with a case report)

Objective:To observe the effect of CAD/CAM all ceramic crown after using diode laser to dentine dehy-persensitivity. Methods:One case of 13-23/33-43 PFM bridge with dentine hypersensitivity symptom,gingiva recession,in-complete marginal,and disharmony color were restored by chair-side CAD/CAM all ceramic crown and diode laser to dentine dehypersensitivity in the same time. The clinical effect of was evaluated by modified United States Public Health Service standard after three months. Results:The chair-side CAD/CAM lithium disilicate glass all ceramic crowns had the perfect color,realistic shape, marginal integrity, and good retention. Hot and cold stimulation did not cause dentin hypersensitivi-ty. The morphology of gingiva was normal,healthy,and no bleeding during probing. Conclusion:The diode laser can effective-ly reduce and eliminate dentine hypersensitivity.
