There are
three different categories
used to arrange gingival fibers.
What are the different types of gingival fibers?
Semicircular fibers
: fibers which go through the facial and lingual gingiva surrounding each tooth. They attach to the interproximal surfaces of the same tooth. Transgingival fibers: fibers which run between two non-adjacent teeth.
What are gingival fibers made of?
Gingival fibers are the connective tissue fibers which are found in the gingival tissue adjacent to the teeth. They aid in holding the gum tissue firmly against the teeth. They are primarily composed of
type I collagen, however, type III fibers are also involved
. These fibers connect the tooth to the gingival tissue.
What are the Dentoalveolar fibers?
The dentoalveolar fibre group consist of
five oriented principal fibre groups
which insert into the dentoalveolar group and function to resist forces and movement: alveolar crest, horizontal, oblique, apical and interradicular. … The ligament fibre bundles do not all insert into the alveolar bone.
What are Supracrestal Fibres?
Supracrestal fiberotomy is
a surgical technique that divides the free gingival and transseptal fibers around rotated teeth that have been corrected orthodontically
. This report examines the rationale of the procedure in addition to its applications, indications, and contraindications.
What is the function of gingival fibers?
The gingival fibers are the connective tissue fibers found in the gingival tissue next to the teeth. They
help hold the gum tissue firmly against the teeth
. They primarily consist of type I collagen, but type III fibers are also involved. These fibers attach the tooth to the gingival tissue.
Where are Sharpey’s fibers found?
In the teeth, Sharpey’s fibres are
the terminal ends of principal fibres (of the periodontal ligament)
that insert into the cementum and into the periosteum of the alveolar bone.
What is Fibre in teeth?
Transseptal fibers (H)
extend interproximally over the alveolar bone crest and are embedded in the cementum of adjacent teeth; they form an interdental ligament. These fibers keep all the teeth aligned. These fibers may be considered as belonging to the gingival tissue because they do not have an osseous attachment..
What is a Luxated tooth?
Tooth luxation is
the dislodgement of a tooth
, sometimes invisibly, that occurs when trauma disrupts the ligaments and tissues holding the tooth in place.
Which substance is the hardest calcified material in the body?
- Enamel is the hardest, white outer part of the tooth. …
- Dentin is the layer underlying the enamel. …
- Pulp is the softer, living inner structure of teeth. …
- Cementum is a layer of connective tissue that binds the roots of the teeth firmly to the gums and jawbone.
What is Supracrestal attachment?
The term “biologic width” is replaced by “supracrestal tissue attachment”, consisting
of junctional-epithelium and supracrestal connective tissue
. • An infringement of restorative margins within the supracrestal connective-tissue attachment is associated with inflammation and loss of periodontal supporting tissue.
What is 7th key of occlusion?
Boltons ratio, seventh key of occlusion aids
in analyzing the proportionality of the maxillary and mandibular teeth
. This analysis helps in diagnosing, analyzing and treating a case into a harmony resulting into structural and functional stability of upper and lower arch in any given case.
What are circular fibers?
The circular fibers (Müller’s muscle, Rouget’s muscle) are
internal to the meridional ones
, and in a meridional section appear as a triangular zone behind the filtration angle and close to the circumference of the iris. They are well-developed in hypermetropic, but are rudimentary or absent in myopic eyes.
What is gingival fiber incision?
A fiberotomy or pericision is
an orthodontic surgical procedure designed to sever the gingival fibers around a tooth
. It usually reduces the tendency to relapse of tooth rotations corrected by dental braces or other treatments.
What is Dentogingival unit?
The dentogingival unit (DGU) has been described as
a functional unit composed of the epithelial attachment and connective tissue attachment of the gingiva
– both of which afford biological protection (1).
What is the interdental papilla in dentistry?
The interdental papilla is
a component of the gingiva
which is present between the proximal surfaces of the teeth occupying the cervical embrasure space which extends to fill the lingual, buccal, and occlusal pyramidal space of the interdental space [1].
