まとめ
アルベオラの骨の厚さは切断器の傾きに大きな影響を与え,頭と下の間には地域的な違いが認められる. 骨の評価を伴う複雑な矯正治療の場合には,コンビームコンピュータトモグラフィー (CBCT) が不可欠です.
科学分野:
- 矯正歯科
- 歯科 画像検査
- 歯周病学
背景:
- 切断器の位置は 矯正治療の目標と長期の安定性にとって重要です
- 切断器の最適な位置付けには,筋肉によってバランスをとった 軟骨の骨髄部分に配置する必要があります.
- 不適切な矯正は 根の吸い込みや骨の折れや窓の形成などの 合併症を招きます
研究 の 目的:
- アルベオラ骨の厚さと切り口の傾きとの関係に関する文献を体系的にレビューする.
- この関係を評価する上でコーンビームコンピュータトモグラフィ (CBCT) の役割を評価する.
主な方法:
- PRISMAのガイドラインに従って体系的なレビューが行われました.
- 検索は2024年7月までのPubMed,Scopus,Cochrane Libraryを含み,日付や言語の制限はありませんでした.
- 研究タイプにはRCT,症例対照,コホート研究が含まれ,レビュー,メタ解析,症例報告は含まれなかった.
主要な成果:
- 最初 の 捜索 に よっ て 167 件 の 記事 が 見つかっ た が,二重 な 記事 を 削除 し た とき の 記事 は 92 件 に 減少 し まし た.
- 最終的に選出された 8 件の論文は 体系的なレビューの基準を満たした.
- このレビューでは,アルベオラ骨の厚さと切り口の傾きとの間に有意な関連が確認された.
結論:
- アルベオラの骨の厚さは地域によって異なるが,上頭部にはより厚い口腔骨があり,下口部にはより薄い唇骨がある.
- CBCTは,重度の不一致,骨の欠陥,または膜の限界を超えた複雑な症例に不可欠です.
- 安全な矯正治療の計画に関する臨床ガイドラインを精進するために,標準化された方法と多様な縦断研究が必要です.

01:27Cranial Bones: Lateral View
2.6K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:14Cranial Bones: Superior and Posterior View
2.8K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:08Overview of the Skull
5.2K
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

01:21Tooth Anatomy

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...

01:29Bone Formation by Intramembranous Ossification
7.3K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

01:22Sutures of the Skull
7.6K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
