What is dental fenestration?
Fenestration is an isolated area in which the tooth root is denuded of bone and the root surface is covered only by periosteum and overlying gingiva. Mucosal fenestration is a clinical entity in which the overlying gingiva or mucosa is also denuded thus the root is exposed to the oral cavity.
What is gingival fenestration?
Gingival fenestration is an opening through oral keratinized tissue, usually unattached, that is observed in thin gingiva, with usually thick subgingival calculus deposits. This lesion is seen infrequently, but may be more common than has been reported; lack of symptoms may inhibit patient awareness.
What is mucogingival surgery?
The term Mucogingival Surgery was proposed by Friedman in 1957 to indicate any surgery “designed to preserve attached gingiva, to remove frena or muscle attachment, and to increase the depth of the vestibule”.
Which of the following is mucogingival surgery?
mucogingival surgery or plastic surgery of muco-gingival tissue is a surgical procedure targeted to correct and eliminate anatomic, developmental and traumatic alterations of gingiva.
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 Mucoperiosteal flap?
Oral surgical flap by definition is the operation in which a portion of the mucoperiosteal tissue is surgically detached from the underlying bone for better access and visibility.
What is Resective osseous surgery?
RESECTIVE OSSEOUS SURGERY 8/34 defined as the procedure by which changes in the alveolar bone can be accomplished to rid it of deformities induced by the periodontal disease process or other related factors, such as exostoses and tooth supra eruption.
What is alveolus in dentistry?
The alveolar process is the thick ridge of bone in the jaw that holds the dental alveoli, or tooth sockets. The dental alveoli hold the roots of the teeth in place, and in case of a dental implant, the alveolar process holds implant hardware in place.
What is flap elevation?
Flap elevation decreases the bone volume fraction and density of medullary bone in the surgical area, allowing for the acceleration of tooth movement.
Gingival fenestration means the exposure of the tooth due to loss of the overlying bone and gingiva. Though treatment of mucosal fenestration occurring in association with chronic periapical inflammation has been reported previously, the occurrence and treatment of gingival fenestration have not been documented in great detail.
What is the difference between dehiscence and fenestration of tooth?
Fenestration and Dehiscence are two similar conditions of Tooth which are similar due to bone loss around the tooth but are different by the type of bone loss or bone surrounding it. To understand the differences first let us know about What is Fenestration and What Dehiscence:
What is fenestration of bone?
The loss of bone is at least 4 mm apical to the margin of the inter-proximal bone. Fenestration is classified based on their apicocoronal location in relation to the root length. It is divided into four types –
What is fenestration of the maxilla?
A fenestration develops when there is no defect seen on the alveolar margin but rather a window-like structure exposes the root surface at the middle or the lower third of the root. Fenestration are usually seen in the upper jaw bone (maxilla) somewhere between the first molar and the canines.
