概括
这项研究发现,在使用狭窄或标准直径的牙科植入物支柱时,在12个月后,植入周边边缘骨水平没有显著差异. 临床结果和患者报告的结果在两组之间也相似.
科学领域:
- 牙科植入物学 牙科植入物学
- 牙修复 牙修复 牙修复 牙修复 牙修复
- 牙周病学 牙周病学
背景情况:
- 植入周边边缘骨损失是植入成功的一个关键指标.
- 体直径可能会影响周围植入物骨水平.
- 对于狭窄与标准支柱的比较数据有限.
研究的目的:
- 为了比较12个月的围部植入边缘骨水平变化.
- 评估与不同支柱直径相关的临床结果和并发症.
- 评估患者报告的结果和审美评价.
主要方法:
- 随机对照试验,包括28名部分牙患者.

01:40Bone Remodeling
38.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
