Technology: major soft enamel, bite version (etching), stamping, injection from (fill oil), silk screen, Dijiao, die casting, Kirschner printing.
主要工艺有：软珐琅、咬版(蚀刻)、冲压、注漆(填油)、丝印、滴胶、压铸、柯式印刷等。
Enamel is almost completely transparent in the near-infrared spectrum, allowing OCT to create highly detailed images of teeth as well as soft tissue.
由于珐琅质在近红外光谱端近乎完全透明，因此oct可以形成牙齿和软组织的高精确图像。
In contrast, the KEY III is suitable for the treatment of soft tissue and hard tissue (enamel and bone), and in periodontology for gentle calculus removal.
相反，KEYIII则适用于治疗软组织和硬组织(牙釉质和牙骨质)，在牙周病学中可轻柔地去除结石。
Soft clean white surface of the teeth factor, safe and effective, not to hurt the enamel.
亮白因子柔和洁净牙齿表面，安全有效，不伤牙釉质。
