01:40Overview of Metabolism
38.7K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

01:19Overview of Functional Groups
16.7K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, certain functional groups will make a molecule hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each functional group is a unique...

01:10Pharmacokinetics: Overview
9.7K
Pharmacokinetics is a scientific discipline that focuses on the journey of a drug within the body, encompassing four key stages: absorption, distribution, metabolism, and elimination. The first stage, absorption, involves the drug's transfer into the bloodstream. Several factors dictate the extent and speed of this process. For example, the liver often metabolizes oral drugs before they reach systemic circulation, leading to only partial absorption. In contrast, intravenous (IV)...

01:13Bioavailability: Overview
4.6K
Bioavailability refers to the proportion of an unaltered drug that, after administration, enters the systemic circulation and can be distributed to the desired action site. Factors such as gastrointestinal (GI) absorption and liver biotransformation influence the bioavailability of a drug when it is administered orally. When a drug is administered intravenously, it enters the systemic circulation directly; by definition, its bioavailability is assumed to be 100%. The bioavailability of an...

00:59Uncertainty: Overview
1.8K
In analytical chemistry, we often perform repetitive measurements to detect and minimize inaccuracies caused by both determinate and indeterminate errors. Despite the cares we take, the presence of random errors means that repeated measurements almost never have exactly the same magnitude. The collective difference between these measurements - observed values - and the estimated or expected value is called uncertainty. Uncertainty is conventionally written after the estimated or expected value.

01:06Potentiometry: Overview
4.6K
Potentiometry is an analytical technique that measures the potential difference between two electrodes in an electrochemical cell without drawing any significant current that could alter the solution's composition. This method employs an indicator electrode, which exchanges electrons with the analyte solution, and a reference electrode with a constant potential. Each electrode is immersed in a solution comprised of two half-cells. In a conventional setup, the reference electrode serves as...

Summary
Orthodontic implants offer superior maxillary first molar movement compared to traditional anchorage methods. While reviews show varied success rates, implants are a significant advancement in orthodontic anchorage, though most existing reviews lack high quality.
Area of Science:
- Orthodontics
- Dental Implantology
Background:
- Implant anchorage is crucial in orthodontics, with increasing applications since their development.
- Existing reviews on orthodontic implants lack comprehensive evaluation.
Purpose of the Study:
- To comprehensively evaluate the effects of orthodontic implants using data from published review articles.
- To assess the efficacy and safety of orthodontic implants.
Main Methods:
- Systematic electronic search of databases (Cochrane Library, Medline, Embase, Ebsco, Sicencedirect) for relevant reviews.
- Manual search of specific orthodontic journals and identification of reviews on orthodontic implants.
- Quality assessment of included reviews using the Assessment of Multiple Systematic Reviews (AMSTAR) tool.
Main Results:
- 23 reviews were included in the analysis, with most being of less than moderate quality.
- Implant anchorage demonstrated superior movement of the maxillary first molar compared to traditional methods.
- Success rates of orthodontic implants varied widely across the reviewed studies.
Conclusions:
- Orthodontic implants represent a significant advancement in anchorage, particularly for complex tooth movements.
- Further high-quality systematic reviews are needed to fully elucidate implant efficacy and safety.
- Maxillary first molar movement is notably enhanced with implant-supported anchorage.
