What is cribriform plate in alveolar bone?
The alveolar process is the lining of the tooth socket and also known as the alveolus. While the alveolar process is made from compact bone, it can also be called the cribriform plate because it contains holes where Volkmann canals pass from the alveolar bone into the PDL.
What is alveolar bone proper?
The alveolar bone, also called the alveolar process, is the part of the jaw that holds the teeth. The bone here supports the roots of the teeth and keeps them in place.
Where is the alveolar bone proper located?
The alveolar bone is located on the jaw bones which hold the teeth. In humans, these bones that contain the teeth are the maxilla and the mandible. The curved portion of each alveolar process on the jaw is the alveolar arch.
What are the two layers of the alveolar bone known as?
Alveolar bone can be divided into two main parts: a thin layer of compact (radiodense) bone (the ‘cortex’ of alveolus) that lines the alveolus proper, in which Sharpey’s fibers insert, that is radiographically termed the lamina dura (lamina dura denta).
How long does it take to lose bone after tooth extraction?
Bone loss can occur very quickly after tooth extraction, often in as little as six weeks, so it is important to have a plan for replacement ready.
How do you regrow an alveolar bone?
Abstract. Background: Alveolar bone is a critical tissue for tooth retention; however, once alveolar bone is lost, it may not spontaneously regenerate. Currently, bone grafts or artificial bone is commonly used for alveolar bone regeneration therapy.
What does widened PDL indicate?
Up to 100% of patients with progressive systemic sclerosis show this sign.36,37 Widening of the PDL is an early sign of progressive systemic sclerosis, which might help dental practitioners establish timely diagnosis through appropriate laboratory tests.35 In patients taking bisphosphonates, PDL widening can be a good …
What causes widening of PDL?
According to Auluck,5 widening of the PDL space is due to the involvement of the masticatory muscle, which becomes bulky, leading to an increased occlusal load and primary trauma from occlusion. Mehra6 suggested that an increase in the collagen synthesis in scleroderma may be the possible cause of PDL space widening.
What is the function of the cribriform plate?
Cribriform plate. It is perforated by foramina for the passage of the olfactory nerves and the anterior ethmoidal nerves to the upper part of the nasal septum, the latter of those to the superior nasal concha. The lateral lamella forms the lateral border of the plate.
What is the alveolar bone proper?
However, the alveolar bone proper is the area of bone that comes directly into contact with the root of a tooth, or the lining of the socket. The alveolar bone proper is hard, compact bone and not soft, spongy bone. When a dental implant is placed, it comes into direct contact with the alveolar bone proper.
Where is the crest of the alveolar bone located?
The crest of the alveolar bone is normally located around 1 mm below the cemento-enamel junction. Blood vessels and nerves run through the alveolar bone and perforate the cribriform plate. The majority of these blood vessels and nerves supply the periodontal ligament.
What is the difference between alveolar bone and cortical bone?
The alveolar bone proper is also called as “ Cribriform plate ” due to the presence of perforations and canals for the entry of vessels and nerves. Cortical bone contains cortical plates which have perforations in the anterior teeth, for the entry of blood vessels into the inner parts of the teeth.
