Summary
Mini-screw assisted distalization effectively moved lower teeth, including molars, premolars, and canines, to correct mild Class III malocclusion. This orthodontic approach showed minimal relapse after treatment, offering a stable solution.
Area of Science:
- Orthodontics
- Dental Implantology
Background:
- Mild Class III malocclusion requires effective treatment strategies.
- Mini-screw implants offer skeletal anchorage for orthodontic tooth movement.
Observation:
- Two mini-screws were placed in the mandibular inter-root bone for anchorage.
- Distalization of lower molars, premolars, and canines was performed using the mini-screws.
Findings:
- Successful distalization of the entire lower dentition was achieved.
- The orthodontic treatment duration was approximately 2.5 years, with 1 year dedicated to molar distalization.
- Minimal relapse was observed during the post-retention phase.
Implications:
- Mini-screw assisted distalization is a viable option for correcting Class III malocclusion.
- This technique can lead to predictable dentoalveolar changes with long-term stability.

The identity of a substance is defined not only by the types of atoms or ions it contains but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the water molecule, which has only one, the two substances exhibit very different properties.

01:12Antiarrhythmic Drugs: Class III Agents as Potassium Channel Blockers
1.9K
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...

01:16Self-Locking Screw
2.4K
A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.

01:21Screw: Problem Solving
689
In mechanical engineering, the interaction between a threaded screw shaft and a plate gear involves analyzing the resisting torque on the plate gear that can be overpowered when a specific torsional moment is applied to the shaft. To better comprehend this concept, consider a generic situation with a threaded screw shaft with a given mean radius and lead and a plate gear with a specified mean radius. The coefficient of static friction between the screw and gear is also provided.

1.6K
Screws are characterized by a helical ridge known as a thread wrapped around a cylindrical shaft. They are commonly used as fasteners to hold objects together or to transmit power and motion in machines. One type of screw that is particularly useful for transmitting power is the square-threaded screw.

03:43Applications of the Ideal Gas Law: Molar Mass, Density, and Volume
63.2K
The volume occupied by one mole of a substance is its molar volume. The ideal gas law, PV = nRT, suggests that the volume of a given quantity of gas and the number of moles in a given volume of gas vary with changes in pressure and temperature. At standard temperature and pressure, or STP (273.15 K and 1 atm), one mole of an ideal gas (regardless of its identity) has a volume of about 22.4 L — this is referred to as the standard molar volume.
