What is alveolar crest?

The alveolar crest is the most cervical rim found in the alveolar bone proper. When it is healthy, the alveolar crest is slightly apical to the cementoenamel junction (CEJ) by about 1.5-2 mm. The alveolar crests of the adjacent teeth are also uniform in height along the jaw when they are healthy.

What is the socket of the tooth?

The socket is the hole in the bone where the tooth has been removed. After a tooth is pulled, a blood clot forms in the socket to protect the bone and nerves underneath. Sometimes that clot can become dislodged or dissolve a couple of days after the extraction.

What does the alveolar bone do?

Alveolar bone is that part of the maxilla and mandible which supports the teeth by forming the “other” attachment for fibres of the periodontal ligament (Fig. 1.148).

Are the tooth sockets joints?

Gomphoses line the upper and lower jaw in each tooth socket and are also known as peg and socket joints. These joints have a very limited range of mobility so the teeth are held firmly in place.

What is fenestration and dehiscence?

Fenestration is the condition, in which the bony coverage of the root surface is lost, and the root surface is only covered by the periosteum and gingiva. In such lesions, marginal bone is intact. When this bone defect spreads toward the marginal bone, it is called dehiscence.[1]

Why is it called alveolar process?

The term alveolar (‘hollow’) refers to the cavities of the tooth sockets, known as dental alveoli. The alveolar process is also called the alveolar bone or alveolar ridge. The curved portion is referred to as the alveolar arch. The alveolar bone proper, also called bundle bone, directly surrounds the teeth.

What is dry socket pain?

Overview. Dry socket (alveolar osteitis) is a painful dental condition that sometimes happens after you have a permanent adult tooth extracted. Dry socket is when the blood clot at the site of the tooth extraction fails to develop, or it dislodges or dissolves before the wound has healed.

What are the four types of teeth?

We have four different types of teeth, with each type serving a particular purpose for eating and chewing.

When does dry socket happen?

Dry socket is a condition that can occur after tooth removal. It usually happens 3–5 days after surgery. Dry socket causes intense pain because it exposes the nerves and bones in the gum. Dry socket, or alveolar osteitis, can last for up to 7 days.

What is the alveolar process made of?

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.

How does alveolar bone develop?

The alveolar bone begins to first form by an intramembranous ossification with in the ectomesenchyme surrounding the developing tooth. This first formed bone is called as woven bone is less organized and is replaced with more organized lamellar one. When a deciduous tooth is shed, its alveolar bone is resorbed.

What is alveolar bone loss?

Cumulative alveolar bone loss results in a weakening of the supporting structures of the teeth and predisposes the patient to tooth mobility and loss. It is one of the hallmarks of periodontitis.

What is tooth socket made of?

34.2. The alveolar bone is that part of the mandibular and maxillary bone which surrounds the teeth and forms the tooth sockets. The bone of the tooth socket is a dense cortical plate into which the principal fibers of the periodontal ligament are inserted, referred to as Sharpey’s fibers.

What are ligaments?

A ligament is a fibrous connective tissue which attaches bone to bone, and usually serves to hold structures together and keep them stable.

What is gingiva?

(JIN-jih-vuh) The tissue of the upper and lower jaws that surrounds the base of the teeth. Also called gums.

What is osseous crater?

Osseous Craters: Craters are cup- or bowl-shaped alveolar. defects in inter-alveolar bone with bone loss approxi- mately equal on the contiguous roots or the concavities. present in the crest of inter-dental alveolar bone and are. confined within the facial and lingual bony walls.

What does Abfraction mean?

Abfraction (AF) is the pathological loss of tooth substance caused by biomechanical loading forces that result in flexure and failure of enamel and dentin at a location away from the loading.

What is a fenestrated wall?

Fenestrated walls, also known as fenestrated planes, are used as a kind of video surveillance utilized in Derse. They consist of a wall panel made up of four separate windows used to show events elsewhere – these walls can be broken, and entered.

What does alveolar process mean?

The alveolar process is the horizontal portion of the maxilla that holds the tooth roots. b. Alveoli for the tooth roots are present all along the alveolar process, except where these have been resorbed following the loss of teeth.

Where is attached gingiva?

The gingival sulcus, or crevice, is therefore created between tooth and mucosa; its depth varies from 0.1 to 0.3 cm. The attached gingiva extends from the free gingival groove to the beginning of the alveolar crest and is continuous with the alveolar mucosa.

Where is alveolar ridge situated?

The alveolar ridge is a small protuberance just behind the upper front teeth that can easily be felt with the tongue.

What are the warning signs of dry socket?

The symptoms of dry socket can vary but may include:

Can dry socket heal on its own?

In most cases, dry socket will heal on its own, but as the site heals patients will likely continue to experience discomfort. If you do choose to treat dry socket at home, you need to clean the wound with cool water, irrigate the socket with saline, and keep gauze over the socket.

Will antibiotics heal dry socket?

Antibiotics are only rarely used to treat dry socket. Patients with a compromised immune system or a history of dry socket may be prescribed a single-dose antibiotic when the tooth is removed to prevent infection.

What is the milk teeth?

Deciduous teeth — also known as baby teeth, primary teeth, or milk teeth — are your first teeth. They start developing during the embryonic stage and start to erupt through the gums about 6 months after birth. All 20 of them are typically in by age 2½.

What are premolars used for?

Premolars Premolars, or bicuspids, are used for chewing and grinding food.

What are human fangs called?

Canines. Canines are the sharp, pointed teeth that sit next to the incisors and look like fangs. Dentists also call them cuspids or eyeteeth. Canines are the longest of all the teeth, and people use them to tear food.

When can you stop worrying about dry socket?

This risk is present until you’re fully healed, which may take 7 to 10 days in many cases. Dry socket occurs when the blood clot that should have formed in the socket after your extraction is either accidentally removed or never formed in the first place. Dry socket is no longer a risk once the site is healed.

Will swallowing cause dry socket?

Swallowing your saliva will create enough pressure to stop the residual bleeding and stabilize the blood clot. Swallowing your saliva will prevent DRY-SOCKET PAIN.

How long does it take the hole to close after tooth extraction?

When your tooth is extracted from your jaw, there is trauma to the jaw bone and this will take longer to heal than the gum tissue. The bone will start to heal after one week, nearly fill in the hole with new bone tissue by ten weeks and completely fill in the extraction hole by four months.
