Summary
Combining self-ligating brackets with surgical methods, low-level laser therapy, or infrared light significantly accelerates adult orthodontic tooth movement. These methods show no adverse periodontal effects, though more research is needed.
Area of Science:
- Orthodontics
- Dental Technology
- Periodontology
Background:
- Self-ligating brackets are widely used in orthodontics.
- Accelerating orthodontic tooth movement is a key area of research.
- The effectiveness and safety of adjunctive acceleration methods require thorough evaluation.
Purpose of the Study:
- To assess the efficacy of acceleration techniques combined with self-ligating brackets for adult orthodontic treatment.
- To investigate the impact of these combined interventions on the rate of tooth movement.
- To identify any associated side effects on periodontal tissues.
Main Methods:
- A systematic review of randomized controlled trials (RCTs) and controlled clinical trials (CCTs).
- Electronic database searches (PubMed, Scopus, Google Scholar, EMBASE) from 1990 to 2021.
- Risk of bias assessment using Cochrane's tool.
Main Results:
- Combining self-ligating brackets with flapless corticotomy, low-level laser therapy (LLLT), or infrared light accelerated tooth movement by 20-50%.
- Surgical methods (flapless corticotomy) showed acceleration of 43-50%.
- LLLT resulted in 20-50% acceleration, and infrared light in 22% acceleration.
- Vibrational forces did not significantly accelerate tooth movement.
- No significant adverse effects on periodontal tissues were reported for the effective methods.
Conclusions:
- Flapless corticotomy, LLLT, and infrared light, when combined with self-ligating brackets, are effective in accelerating orthodontic tooth movement in adults.
- Current evidence suggests these acceleration methods are safe for periodontal tissues.
- Further high-quality research is recommended to confirm efficacy and investigate potential side effects thoroughly.

A slider-crank mechanism converts rotational motion from the crank into linear motion of the slider or vice versa. This mechanism consists of three main parts: the crank, the connecting rod, and the slider. The movement of the slider-crank is an example of general plane motion as the fluctuating angle between the crank and the connecting rod. Consider a segment AB where point A is at the end of the slider and point B is on the diametrically opposite end to point A, on a crack. The variance in...

01:22Relative Motion Analysis using Rotating Axes - Acceleration

Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame. The absolute velocity of point B is determined by adding the absolute velocity of point A, the relative velocity of point B in the rotating frame, and the effects caused by the angular velocity within the rotating frame.
