概括
外源性骨块 (XBBs) 显示侧脊增强可接受的生存率,为植入物提供足够的骨体积. 然而,与自身骨块 (ABB) 相比,植入物存活率较低.
科学领域:
- 在口腔外科手术中.
- 牙周病学 牙周病学
- 再生医学是一种再生医学.
背景情况:
- 侧脊增强对于牙植入成功至关重要.
- 外源性骨块 (XBBs) 为自身性骨块 (ABBs) 提供了替代方案.
- XBBs的临床结果需要彻底调查.
研究的目的:
- 为了评估异源性骨块 (XBBs) 在侧脊增强中的临床结果.
- 专注于骨增益,移植存活率和植入物存活率.
- 在数据允许的情况下,将XBB与自身骨块 (ABB) 进行比较.
主要方法:
- 在PubMed,Embase和ClinicalTrials.gov的系统搜索到2024年3月.
- 包括随机对照试验 (RCT) 和前性队列研究.
- 分析了水平骨增益,再吸收,移植和植入物存活率;使用RoB2和NOS评估了研究质量.
主要成果:
- 分析包括4个RCT和5个队列研究 (120个部位,141个植入物).
- 权重平均水平骨增益:4.38毫米;再吸收:0.85毫米.
- 在RCT中,XBB与ABB相比,水平骨益显著增加 (0.72毫米的差异). 权重的移植存活率:91.3%;植入物存活率:84.3%. 组织学分析显示11.6-29.8%的重要骨和7.3-21%的再吸收.
结论:
- 异种骨块 (XBBs) 提供了足够的骨体积和可接受的生存率,用于侧脊增强.
- 植入于XBB增强部位的植入物与自身骨块 (ABB) 增强部位的植入物相比,存活率不太好.
- XBB是一种可行的选择,但需要仔细选择患者并考虑植入物生存结果.

Bone Structure
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.
Classification of Bones
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.

Gross Anatomy of Bone
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in adults, it...

Bone Disorders
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...
