|August 29, 2025
概括
使用螺丝式或共度式植入物假体进行即时加载的完整牙科康复,成功率很高. 螺丝松动是最常见的问题,而共度假肢则有更多的脱落.
科学领域:
- 牙科学
- 牙整形
- 植入物学
背景情况:
- 在全面的牙科康复中越来越多地使用即时加载协议.
- 在临床决策中,比较螺丝式和共度式植入物假体至关重要.
研究的目的:
- 分析立即加载完整康复的临床结果.
- 在生存率和成功率方面比较螺丝固定与共度植入假肢.
主要方法:
- 对203名患者进行了回顾性研究,其中1356名患者使用了261个固定假肢.
- 评估植入物存活率,假肢成功,并发症 (技术和生物).
- 使用奇方测试进行统计分析,以比较螺丝固定和共度组.
主要成果:
- 整体植入物存活率高 (98%),整体假肢成功率为89. 3%.
- 在螺丝固定和共度组之间,植入物存活率或假肢成功率没有统计学意义上的差异.
- 螺丝松动 (4. 2%) 是最常见的并发症;共度假肢脱落的发生率更高 (9. 2%).
结论:
- 这两种即时负荷康复疗法都具有很高的成功率和较低的并发症发生率.
- 螺丝松动是两种方法的主要并发症.
- 与螺丝固定假肢相比,共度假肢的脱落率明显高.

01:21Drug Accumulation During Multiple Dosing: Repetitive IV Injections
Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...
01:24Drug Accumulation During Multiple Dosing: Intermittent IV Infusions
Intermittent intravenous (IV) infusion is a method of drug administration where medications are delivered over short infusion periods followed by intervals of no drug delivery. This approach helps to prevent sustained high drug concentrations in the bloodstream, reducing the risk of adverse effects associated with prolonged exposure. Unlike continuous infusion, steady-state concentrations may not be achieved during a single dosing cycle but can be reached through repeated...
