What is alveolar in dentistry?
The alveolar process, which is also called the alveolar bone, is the thick ridge of bone which contains the tooth sockets. 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.
Is the alveolar margin the same as the alveolar process?
The coronal margin of the alveolar process, where the cribriform and cortical plates meet, is the alveolar margin. The alveolar margin is typically 1–2 mm apical to the cemento-enamel junction so that there is a band of root cementum residing coronal to the alveolus.
What is the alveolar bone proper?
BONE: ALVEOLAR BONE PROPER: Compact bone that composes the alveolus (tooth socket). Also known as the lamina dura or cribiform plate, the fibers of the periodontal ligament insert into it.
What is alveolar ridge of mandible?
The alveolar ridge is an extension of the maxilla (the upper part of the jaw) and the mandible (the lower part of the jaw) and is a bony ridge that holds the sockets of the teeth. The alveolar ridge is a critical anatomical structure for healthy teeth and successful dental implants.
Where is the alveolar margin?
The alveolar ridge (/ælˈviːələr, ˌælviˈoʊlər, ˈælviələr/; also known as the alveolar margin) is one of the two jaw ridges, extensions of the mandible or maxilla, either on the roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth.
Where is the alveolar nerve?
The inferior alveolar nerve or inferior dental nerve is a mixed sensory and motor branch of the posterior division of the mandibular division of the trigeminal nerve, located in the pteryogomandibular space of the oral cavity/masticator space.
Which facial bones have alveolar processes?
The alveolar process (alveolar bone) is the thickened ridge of bone that contains the tooth sockets on bones that bear teeth (maxilla and mandible). On the maxilla, the alveolar process is a ridge on the inferior surface. It makes up the thickest part of the maxilla.
What is that thing behind your front teeth?
What Is a Frenum? In the mouth, a frenum or frenulum is a piece of soft tissue that runs in a thin line between the lips and gums. It’s present on the top and bottom of the mouth. There’s also a frenum that stretches along the underside of the tongue and connects to the bottom of the mouth behind the teeth.
What is the life span of the alveolar bone?
Alveolar bone loss A key indication of resorption is when scalloped erosion occurs. This is also known as Howship’s lacuna. The resorption phase lasts as long as the lifespan of the osteoclast which is around 8 to 10 days.
Where is the alveolar ridge in the mouth?
The alveolar ridge (/ ælˈviːələr, ˌælviˈoʊlər, ˈælviələr /; also known as the alveolar margin) is one of the two jaw ridges, extensions of the mandible or maxilla, either on the roof of the mouth between the upper teeth and the hard palate or on the bottom of the mouth behind the lower teeth.
What makes up the root of the alveolar bone?
The alveolar bone is made up of two distinguishable parts, alveolar bone proper and supporting alveolar bone. The alveolar bone proper is made up of thin lamellae of bone (cortical bone) which surrounds the root.
Is the alveolar ridge necessary for dental implants?
Adequate alveolar ridge bone height is necessary for patients to receive and benefit from dental implant placement. Regeneration of the alveolar ridge remains a clinical challenge.
The alveolar bone crest more or less parallels the CEJ of the teeth, located 1-3 mm apical to it. This distance increases with age 404. The shape of the alveolar crest depends on many factors, including the contour of the CEJ, degree of tooth eruption and alignment of teeth.
