概括
对前部开口咬伤的Invisalign治疗仅实现了预测咬伤关闭的66.2%. ClinCheck软件高估了治疗结果,影响了清晰对齐器治疗的可预测性.
科学领域:
- 矯正牙科 矯正牙科是一種矯正牙科.
- 牙科技术 牙科技术
背景情况:
- 透明对齐器,像Invisalign一样,理论上可以通过充当封闭性咬伤块来纠正前部开口咬伤.
- 这种建议的机制,限制后部挤出或侵入后牙,缺乏实质性证据.
研究的目的:
- 为了评估Invisalign治疗在纠正前部开口咬伤的准确性.
- 为了将ClinCheck软件的预测结果与初始对齐器序列的实际获得结果进行比较.
主要方法:
- 对76名接受非提取性Invisalign治疗的成年患者进行了追溯分析.
- 使用Geomagic Control X软件对预处理,后处理和预测的ClinCheck立体石版文件进行比较.
- 测量超咬和超喷射,以评估治疗的准确性.
主要成果:
- 获得的开口咬合关闭率约为ClinCheck预测结果的66.2%.
- 基于后部咬牙块或特定牙运动 (前部挤出,后部侵入) 的使用,没有观察到有效性的显著差异.
- 随着两周的对齐器更换间隔,观察到更大的咬合关闭趋势 (平均0.49毫米).
结论:
- ClinCheck软件显著高估了可以通过Invisalign治疗实现的咬合关闭程度.
- 对于前部开口口纠正,Invisalign的可预测性可能低于之前声称的.

01:27Open Angle Glaucoma: Treatment
491
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:03Prediction Intervals
2.3K
The interval estimate of any variable is known as the prediction interval. It helps decide if a point estimate is dependable.
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
