概括
骨固定 (SA) 与大延伸 (MP) 显著提高了III类缺口患者的中脸,鼻子和上唇体积. 与快速 palatal 扩张 (RPE) 和改进的替代快速大扩张和收缩 (Alt-RAMEC) 相比,这种方法提供了优越的软组织形状控制.
科学领域:
- 矯正牙醫和牙臉整形醫學
- 在面研究中使用3D成像.
- 软组织分析在不良闭塞的软组织分析
背景情况:
- 第三类恶性闭塞在软组织形状管理方面存在挑战.
- 大延伸 (MP) 是一种常见的治疗方式.
- 评估与MP结合的不同扩展技术对于优化结果至关重要.
研究的目的:
- 为了比较三种扩张方法 (RPE,Alt-RAMEC,SA) 与MP相结合对软组织形状的影响.
- 用3D立体摄影仪分析软组织变化.
- 为了确定最有效的扩张技术,用于美学软组织修饰.
主要方法:
- 51名患有III类缺陷闭塞的患者 (8-12岁) 根据扩张技术分为三组.
- 治疗涉及快速口腔扩张 (RPE),修改后的交替快速大扩张和收缩 (Alt-RAMEC),或骨固定 (SA) 与大延伸 (MP).
- 在治疗前和治疗后的软组织变化使用3D立体摄影图像进行评估.
主要成果:
- 所有组都显示出显著的软组织变化,包括中脸,鼻子和上唇体积增加,下唇和下巴体积减少.
- 骨固定 (SA) 组在中脸,鼻子和上唇体积中表现出最显著的增加.
- 快速 palatal 扩张 (RPE) 显示出最大的 alar 基宽度增加,而 SA 导致了最多的鼻尖突出和上唇缩小.
结论:
- 骨固定 (SA) 支持的上伸展 (MP) 提供了对软组织美学的优越控制.
- 与RPE和Alt-RAMEC相比,这种方法最大限度地减少了不良的牙和垂直骨副作用.
- SA提供可预测和美观的软组织变化,用于III类缺陷治疗.

01:20Nursing Process for Patient and Caregiver Teaching III: Evaluation and Documentation
2.6K
Evaluation of the teaching process enables the nurse to determine if the patient's learning needs were met and if training was effective. If the expected outcomes are not met, the care plan is revised, and additional education or reinforcement is provided. Nurses can ask questions after the session or obtain feedback to assess the patient's understanding of the topic.
Nurses can use several methods to evaluate patient outcomes. For example, oral questions can assess cognitive learning,...

01:12Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
2.5K
Class III antiarrhythmic drugs are a group of medications that can prolong action potentials in the heart. They achieve this by blocking potassium channels or enhancing inward currents from sodium channels. However, these drugs have a unique property of "reverse use-dependence," which is most pronounced at slower heart rates and can lead to torsades de pointes—a specific type of arrhythmia. However, it is essential to note that excessive QT interval prolongation—a measure of...

204
Self-evaluation is the process by which individuals assess their abilities, behaviors, and characteristics based on feedback from others. Charles H. Cooley observed that a person’s self-perception is primarily influenced by how others see and judge them. He suggested that individuals form their identities based on their interpretations of others' reactions. As a result, social interactions play a crucial role in shaping self-esteem and personal identity. These external evaluations often...

01:08Role of Communication in the Nursing Process III: Evaluation and Documentation
2.1K
A successful patient outcome depends mainly on the evaluation stage of the nursing process. Evaluation determines effectiveness by reviewing what was done previously after the completion of nursing interventions. Every time a healthcare professional steps in or administers treatment, they must reassess or evaluate the action to ensure the intended result. During the evaluation phase, there are three probable patient outcomes:

01:25Drug Classes and Categories
3.1K
Drugs can be classified according to their chemical composition or their intended therapeutic application. For instance, anti-infective agents that possess the ability to eliminate pathogens or suppress their growth and reproduction can be grouped based on the organisms they target or their chemical structure. Furthermore, drugs can be divided into prescription, nonprescription, or controlled substances. Prescription medications, such as antibiotics, require oversight from a licensed healthcare...

01:25Antibody Structure and Classes
9.4K
Antibodies, also known as immunoglobulins, are produced by B cells in response to foreign substances, such as bacteria and viruses. These proteins are critical for recognizing and neutralizing these substances, protecting the body from potential harm.
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.
