Thekey difference在基底骨和牙槽骨之间basal bone is the osseous tissue of themandible and maxilla除了肺泡过程,而牙槽骨是骨衬里的骨头肺泡.
Mandible and maxilla bones are the bones that form the lower jaw and upper jaw respectively. They are two major bones of our face. The mandible is the largest bone that holds the lower teeth. Moreover, it supports mastication. The maxilla is a fixed bone that holds the upper teeth. It is also important in mastication and communication. Basal bone and alveolar bone are two bones of the maxilla and the mandible. Basal bone is the osseous tissue of the mandible and maxilla, while the alveolar bone is the bone lining the alveolus.

什么是基骨?
基底骨是下颌骨和上颌骨的骨组织,不是肺泡过程。因此,基底骨位于肺泡过程以下。换句话说,肺泡过程依赖于下颌骨和上颌骨的基底骨。在下颌体中,基底骨是两个主要分区之一。基底骨形成牙齿骨骼的结构。此外,基底骨包含大多数肌肉附着。甚至在牙齿发育之前,基底骨就开始在胎儿中发育。衰老时,下颌骨和上颌的基础骨的高度往往会增加。
什么是牙槽骨?
Alveolar process is the bone that possesses teeth and alveoli (tooth housings). Aleveolar process and basal bone are located together, and there is no clear separation between them. In fact, the alveolar process rests on the basal bone. The alveolar process consists of alveolar bone, cortical plate andsponge bone. Thus, alveolar bone is the bone that lines alveolus and supports the tooth. It is a highly mineralized tissue. There are two major parts of the alveolar bone as alveolar bone proper and supporting alveolar bone. Alveolar bone proper consists of bundle bone and lamellar bone. It mainly lines the tooth socket. On the other hand, supporting alveolar bone contains cortical plate and supporting spongiosa.
Alveolar bone has 0.1 to 0.5 mm thickness. To supply nerve and blood to the teeth, alveolar bone has numerous perforations that allowblood vessels and nerves. Moreover, alveolar bone undergoes extensive remodelling according to tooth movement and external stimuli. However, the presence and maintenance of the alveolar bone is tooth dependant. Most importantly, following a tooth extraction, the alveolar bone tends to resorb. Alveolar bone develops from the dental follicle.
What are the Similarities Between Basal Bone and Alveolar Bone?
- Both basal bones and alveolar bones are found in maxilla and mandible.
- 因此,它们是下颌骨和上颌骨的一部分。
基底骨和牙槽骨有什么区别?
Basal bone is one of the major parts of the osseous tissue of mandible and maxillae except for the alveolar processes, while the alveolar bone is the bone that lines alveolus. So, this is the key difference between basal bone and alveolar bone. Moreover, functionally, basal bone forms the structure of dental skeletal, while alveolar bone supports teeth. Besides, another difference between basal bone and alveolar bone is that basal bone begins to develop in the fetus, while alveolar bone develops from the dental follicle.
概括– Basal Bone vs Alveolar Bone
Basal bone is the osseous tissue of the mandible and maxilla. It forms the dental skeletal structure. Basal bone is found below the alveolar process. In contrast, basal bone is a part of the alveolar process. It is the thin bone that lines the alveolus. It has numerous perforations in order to allow blood vessels and nerves to reach the tooth. So, this summarizes the difference between basal bone and alveolar bone.
