Classification of alveolar ridge defects
What is alveolar ridge defect?
When teeth are extracted, a certain amount of bone loss or resorption occurs, usually about 30-60%. This loss is typically three-dimensional in nature, with width loss or horizontal deficiency developing to a greater extent than other types of deficiencies.
What are the alveolar ridges?
The alveolar ridge is a small protuberance just behind the upper front teeth that can easily be felt with the tongue. The major part of the roof of the mouth is formed by the hard palate in the front, and the soft palate or velum at…
What is the other name of alveolar ridge?
The term alveolar (/ælˈviːələr/) (‘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.
What is alveolar ridge and its function?
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.
Why is it called the alveolar ridge?
It is so-named because the small jaw ridges are actually the edges of the cavity sockets, or alveoli, that house the roots of teeth.
What is residual alveolar ridge?
“Residual alveolar ridge is that portion of the alveolar ridge and its soft tissue covering which remains following the removal or loss of teeth”.
What is edentulous alveolar ridge?
Alveolar ridge keratosis is a benign, hyperkeratotic patch or plaque that commonly develops on the retromolar pad or edentulous alveolar ridge. It is believed to represent a response to chronic, frictional trauma (i.e., from opposing teeth, prostheses, or foodstuffs during mastication).
What is alveolar ridge augmentation?
Alveolar ridge augmentation is obtained with the placement of titanium mesh above cancellous iliac bone graft. The success rate of alveolar bone volume, width and height is assessed by CT scan. 39. Resorption of iliac cancellous bone graft is directly linked to the width of alveolar bone defect.
Is the alveolar ridge part of the hard palate?
The alveolar ridge (/ˌælviˈoʊlər, ælˈviːələr, 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 is the ridge of a tooth?
The ridges are also known as mamelons. They are rounded bumps on the edge of a tooth. Like the other parts of the tooth’s outer covering, they are made of enamel. In French, the word mamelon means “nipple.” It refers to the way each bump protrudes from a tooth.
What are the ridges in the top of your mouth for?
The hard palate, which composes two-thirds of the total palate area, is a plate of bone covered by a moist, durable layer of mucous-membrane tissue, which secretes small amounts of mucus. This layer forms several ridges that help grip food while the tongue agitates it during chewing.
What is ridge anatomy?
anatomy any elongated raised margin or border on a bone, tooth, tissue membrane, etc.
Where is the alveolar in the mouth?
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 ridges on the hard palate called?
On the ventral surface of hard palate, some projections or transverse ridges are present which are called as palatine rugae.
What are the two holes on the roof of my mouth?
Answer: You may be seeing the Palatine Foramina
These are normal “holes” on either side of the palate at the junction between the hard and soft palate that transmit the Greater and Lesser Palatine nerves.
Is the uvula part of the alveolar ridge?
This is the alveolar ridge. Sounds which involve the area between the upper teeth and this ridge are called alveolars. the hard portion of the roof of the mouth.

What is purpose of the grooves ridges depressions and tubercles in the mouth cavity?
These are ridges and fissures on the chewing surfaces of the teeth. They allow us to grip food as we chew and break it down.
What is the difference between hard palate and soft palate?
The roof of the mouth is known as the palate. The hard palate is the front part of the roof of the mouth, and the soft palate is the back part.
