延迟的牙植入器在原始的大口腔骨缺陷在前大部
概括
牙提取部位的自然愈合,然后进行大气泡分裂手术,在两年内显著增加了骨体积,并保持了骨宽. 这种骨增强技术避免使用骨替代品来放置牙植入物.
科学领域:
- 牙科植入物学 牙科植入物学
- 在口腔外科手术.
- 牙周病学 牙周病学
背景情况:
- 在美学上部区域的膜骨缺陷往往需要增强牙植入物放置.
- 提取插座的自然愈合可能导致骨体积不足,无法立即恢复植入物.
研究的目的:
- 为了研究在提取插座中进行硬组织重塑,经历自然愈合和随后的膜分裂脊椎手术.
- 为了评估骨体积和脊柱宽度的变化,在这种两阶段的牙科植入物手术方法后.
主要方法:
- 对13个切口部摘取部位进行了回顾性评估,这些部位经过了无骨替代品的口愈合,随后进行了延迟的膜裂解和植入物放置.
- 圆束计算机断层扫描 (CBCT) 在术前和术后分析骨体积和骨宽度.
- 使用非参数测试进行的统计分析,显著程度为p < 0.01.
主要成果:
- 两年后观察到100%的植入物存活率,没有植入周围并发症.
- 总骨体积 (p = 0.0105) 和骨顶宽度 (p = 0.0012) 显著增加.
- 平均脊柱宽度增加了+1.4毫米,这表明通过分裂脊柱手术成功增加了骨.
结论:
- 自然的口愈合与延迟的膜分裂相结合,有效地增加了骨体积,并保留了膜骨.
- 这种方法提供了足够的骨增强,可以在没有骨替代品的情况下放置牙植入物.
- 提取后部位增强主要集中在前部区域.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
