まとめ
本研究では、カスタム(インビジブル)および従来(カランジェ)の矯正方法におけるブラケットポジショニングの精度を比較した。両システムとも理想的な配置からの有意な逸脱を示し、前歯のブラケットはより切縁側に位置していた。
科学分野:
- 矯正歯科; 歯科技術
背景:
- 正確なブラケットポジショニングは、効果的な矯正治療に不可欠である。ブラケット設置のばらつきは、治療結果と効率に影響を与える可能性がある。
研究 の 目的:
- インビジブル(カスタム)および修正カランジェ(従来)システムのブラケットポジショニングの精度を評価および比較する。ブラケット設置におけるアンドリュースの処方からの逸脱を評価する。
主な方法:
- インビジブルシステムを使用した11名と修正カランジェ法を使用した15名の合計26名を分析した。デジタルモデルを使用して、顔面軸(FA)点に対するブラケット位置を測定した。有意な逸脱(TSD)が0.5 mmを超える歯を特定し、分析した。
主要な成果:
- 有意な逸脱(69.5%)を示す歯の割合は、インビジブル群(56.65%)と比較して、修正カランジェ群の方が高かった。両システムとも、後歯と比較して前歯において切縁側/咬合側の逸脱が大きかった。逸脱は両治療群ともに主に咬合側または切縁側であった。
結論:
- インビジブルおよび修正カランジェ法はともに、アンドリュースのFA点に対して切縁側/咬合側にブラケットを位置付ける傾向がある。両評価方法ともに、前歯のブラケットポジショニングは後歯よりも一貫して切縁側である。

The Anchoring-and-Adjustment Heuristic

In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Complementation Tests
4.9K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Consider a symmetrical roof truss structure, composed of vertical, diagonal, and horizontal members. The length of each horizontal member is 4 m. The lengths of the vertical members FB and HD are 4 m, while the length of member GC is 6 m. The loads acting at joints F, G, and H are 2 kN, while those at joints A and E are 1 kN.

Systems of Linear Equations in Two Variables

Solving a system of linear equations is a fundamental concept in algebra. A system of equations consists of two or more linear equations involving the same set of variables. One of the most efficient algebraic methods for solving such systems is the substitution method. This technique involves expressing one variable in terms of the other from one equation and substituting it into the second equation. This method is particularly useful when one of the equations is easily rearranged.Consider the...
