|August 22, 2025
まとめ
この研究は,大きな噛み上げ器と 歯茎の裏側に置くことで,前部の切断部を 大きく減らすことが示されています. 影響は個人に異なっており,一貫した噛み上げと過剰な噛み下げの比率が観察されました.
科学分野:
- 歯科
- 矯正歯科
- バイオメカニカルエンジニアリング
背景:
- 前の切歯部が 歯科でよくある問題です
- 歯周病の治療には 歯周病の治療に使われます
- 治療計画において,異なる噛み上げ器の設計の有効性を理解することは極めて重要です.
研究 の 目的:
- 鉄製のベアリングボールを用いて,第1および第2の歯茎の噛み上げの影響を評価する.
- 噛み合わせの縮小を異なるサイズで比較する.
- 臨床前および臨床での測定の信頼性を評価する.
主な方法:
- この研究では,23人の若い成人の歯の鋳型と口内スキャンを使用した.
- 2mmと3mmの直径のステンレス鋼のベアリングボールが,下部第1および第2の歯茎に配置されました.
- オーバーバイトの変化は,クリニック前では鋳型で,クリニックではデジタルスキャンで測定された.
主要な成果:
- 2mmと3mmのベアリングボールは 前部オーバーバイトを大幅に減少させた.
- より大きな球 (3mm) と後部部 (第2の歯茎) は,より大きなオーバーバイトの減少をもたらしました.
- 臨床前および臨床測定では,優れた信頼性 (ICC) の比較結果を示した.
結論:
- 噛み上げ器のサイズと歯茎の位置は 噛みすぎの減少に直接影響する.
- 2mmのボールでは約1. 6:1,3mmのボールでは約1. 4:1でした.
- 噛み上げに対する反応において,個体間での有意な変動が観察された.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
