Summary
Bone grafting in orthognathic surgery may improve healing and stability, but evidence is limited. Further research is needed to confirm benefits and guide clinical decisions on using bone grafts for osteotomy sites.
Area of Science:
- Oral and Maxillofacial Surgery
- Regenerative Medicine
- Biomaterials
Background:
- Bone grafting is utilized in orthognathic surgery to enhance healing and stability after jaw repositioning.
- The decision to employ bone grafts presents a clinical dilemma due to satisfactory outcomes in most cases.
Purpose of the Study:
- To systematically review the existing literature on the use of bone grafts in orthognathic surgery.
- To evaluate the impact of bone grafting on healing, stability, and aesthetic results.
Main Methods:
- A comprehensive literature search was conducted across major databases (PubMed, MEDLINE, Embase, Cochrane).
- Inclusion criteria led to the selection of 48 articles for review after initial screening of 1937 articles.
Main Results:
- Bone grafting generally shows benefits for healing, stability, and aesthetics in orthognathic surgery.
- No significant difference was observed between graft types, though calcium phosphate cement and hydroxyapatite were linked to increased infection rates.
Conclusions:
- There is a notable lack of robust evidence supporting bone grafting at osteotomy sites in orthognathic surgery.
- Proposed guidelines are based on current evidence, but future research is essential for validation.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

01:20Random and Systematic Errors
15.1K
Scientists always try their best to record measurements with the utmost accuracy and precision. However, sometimes errors do occur. These errors can be random or systematic. Random errors are observed due to the inconsistency or fluctuation in the measurement process, or variations in the quantity itself that is being measured. Such errors fluctuate from being greater than or less than the true value in repeated measurements. Consider a scientist measuring the length of an earthworm using a...

13.3K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this...

In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...
