牙齿缺失修复方法
Tooth replacement options

传统的牙缺失修复方案是固定义齿（冠、桥）以及局部或全口的活动假牙，可以满足牙缺失后短期的美学要求。但这些方法都不能防止骨萎缩。冠和桥需要把两个或更多的健康牙齿进行磨削，以支撑牙桥。这会带给健康牙齿蛀牙或牙髓病的风险。如果，被磨削的基牙损坏后，更多牙齿会被牺牲，来做支撑牙桥的基牙。同时，桥下面的骨骼也会继续萎缩。

Traditional treatment options for tooth replacement, Crown & Bridge and full or partial dentures, address the short-term cosmetic problem of missing teeth, but do nothing to stop bone loss. Crown & Bridge also requires that two or more healthy teeth be ground down to serve as abutments (posts) for a bridge, leaving them at a much greater risk for cavities and endodontic failure. If the original abutment teeth fail, more healthy teeth must be sacrificed to serve as posts, while you continue to lose bone beneath the bridge.

然而，采用种植体不会损伤旁边的健康牙齿。种植体可以像天然牙齿一样把咀嚼力量传导到颌骨上，这可以有效地减少骨萎缩。这就是为什么很多领先的牙科机构都将种植牙作为牙缺失修复的标准手段。

With implants, however, the healthy teeth are left alone. Dental implants, like natural teeth, also transmit chewing forces to the jawbone, which reduces bone loss. This is why many leading dental organizations now recognize dental implants as the standard of care for tooth replacement.
