What causes dental fenestration?
A naturally occurring fenestration leaves the exposed root surface in direct contact with either the alveolar mucosa or the gingiva. The condition may be caused by a variety of factors including tooth movement due to orthodontics, pathology (both endodontic and periodontal), root apex contours, and occlusal issues.
What is bone fenestration?
A fenestration is a “window” of bone loss on the facial or lingual aspect of a tooth that places the exposed root surface directly in contact with gingiva or alveolar mucosa. It can be distinguished from the dehiscence in that the fenestration is bordered by alveolar bone along its coronal aspect.
What is dehiscence and fenestration?
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]
How is dental dehiscence treated?
Many surgical techniques are introduced to enhance alveolar bone volume for placing the dental implants. Guided bone regeneration (GBR) is one such established surgical technique for correcting buccal dehiscence defects, along with the use of various barrier membranes for the same.
What is the alveolar process?
The alveolar process, which is also called the alveolar bone, is the thick ridge of bone which contains the tooth sockets. 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 does fenestration mean in construction?
Originating from the Latin word fenestra, meaning window, fenestration refers to the openings in a building’s facade. In simple terms, fenestration can be explained as the arrangement of windows, doors and openings in a building.
What causes dehiscence dental?
Predisposing factors of Dehiscence and Fenestration: Prominent root contours. Malpositioning of teeth. Labial protrusion of root. Thin bony plates.
What are alveoli surrounded by?
Each alveolus is cup-shaped with very thin walls. It’s surrounded by networks of blood vessels called capillaries that also have thin walls. The oxygen you breathe in diffuses through the alveoli and the capillaries into the blood.
What is the difference between alveoli and alveolus?
What is the difference between Alveoli and Alveolus? The only difference between alveoli and alveolus is that alveolus is the singular word of alveoli.
