まとめ
3Dプリントチタンメッシュを用いたガイド下骨再生は、歯科インプラントの骨量を確実に回復させる。この技術は、骨増生が必要な患者において、予測可能な結果と高い臨床的成功率を示す。
科学分野:
- 口腔外科
- 再生医療
- 生体材料工学
背景:
- 歯の喪失後の歯槽骨吸収は、しばしば歯科インプラントの配置を妨げる。
- 3Dプリントチタンメッシュを用いたガイド下骨再生(GBR)は、骨量の回復のための有望な技術である。
- メッシュ露出などの合併症は、現在のGBR法で発生する可能性がある。
研究 の 目的:
- マイクロパーフォレーション加工されたグレード2チタンメッシュを用いたGBR技術の臨床的信頼性と骨増加を評価すること。
- 歯科インプラント処置のための骨増生の予測可能性を評価すること。
- 個別化メッシュ、前庭部スクリュー、自家骨を用いた結果を分析すること。
主な方法:
- 3Dプリントチタンメッシュを用いたGBRを受けた16人の患者の後ろ向き研究。
- メッシュは、ダイレクトメタルレーザー焼結を用いてデジタル設計および製造された。
- 2段階の骨再生処置で、インプラント配置前に最低4ヶ月の治癒期間を設けた。
- 術前および術後のCBCTデータを用いて、計画された骨増生と実際の骨増生を比較した。
主要な成果:
- 全16個のメッシュは合併症や露出なく首尾よく移植された。
- 安全なインプラント処置に必要な十分な骨量が、122〜160日ですべての患者で達成された。
- 計画された骨増生と実際の骨増生との間に有意な差は見られなかった。
結論:
- 個別化されたマイクロパーフォレーション加工されたチタンメッシュを用いたGBR技術は、非常に信頼性が高い。
- この方法は、口腔外科における骨増生のための予測可能な短期臨床結果を提供する。
- 自家骨との組み合わせは、骨再生の成功に寄与する。

Bone Structure
51.9K
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Bone Remodeling
40.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Compact Bone
16.8K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Bone Disorders
5.5K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

The Hyoid Bone
5.2K
The hyoid bone is a small U-shaped bone located in the upper neck at the level of the inferior mandible, with its tips pointing posteriorly. It does not directly articulate with any other bone in the body. The hyoid acts as the attachment site for the tongue, the larynx, and the pharynx. It is held in position by a series of small muscles attached from above or below. These muscles help to move the hyoid up/down or forward/back in coordination with movements of the tongue, larynx, and pharynx...

Spongy Bone
8.1K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
