What is the importance of biological width?

The natural barrier that develops around the teeth and dental implants to protect the alveolar bone from disease and infection is known as the biologic width. As such, biologic width is vital for the preservation of periodontal health and removal of irritation that could damage the periodontium.

What is the biologic width in dentistry?

The biologic width is the distance established from the junctional epithelium and connective tissue attachment to the root surface of a tooth. This is also described as the height between the deepest point of the gingival sulcus and the alveolar bone crest.

What happens when biological width is violated?

Biologic width violation can lead to bleeding or recession of the gingival tissue; chronic inflammation of the gingival tissue, especially immediately around the restoration; the formation of pockets between the gums and teeth; and loss of alveolar bone.

What is the biologic width composed of?

Biologic width describes the combined heights of the connective tissue and epithelial attachments to a tooth.

Who coined the term biologic width?

[Figure 1] Based on this work, the biologic width is commonly stated to be 2.04 mm, which represents the sum of the epithelial and connective tissue measurements. In 1977, Ingber et al. described “Biologic Width” and credited D. Walter Cohen for first coining the term.

What is the new term for biological width?

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.

How much is biologic width?

The Term Biologic Width He found that biologic width was relatively similar on all the teeth in the same individual from incisors to molars, and also around each tooth. He also found the average biologic width to be 2 mm as the Garguilo group did.

How much biologic width do you need?

He also found the average biologic width to be 2 mm as the Garguilo group did. What Vacek found that is clinically important was that biologic width varied between individuals, with some having biologic widths as small as . 75 mm, and others as tall as 4 mm, but statistically the majority followed the 2 mm average.

How long is a biologic width?

What does biological width compose of?

Biologic width (BW) as defined by Cohen is the part of the supracrestal gingival tissues that occupy the space between the base of the gingival crevice and the alveolar crest; it includes the junctional epithelium and the connective tissue element.

What is nup in dentistry?

Necrotizing ulcerative periodontitis (NUP) is characterized by soft tissue necrosis, rapid periodontal destruction, and interproximal bone loss. Unlike other periodontal diseases, it presents substantial necrosis of gingival tissues, and loss of periodontal ligament and alveolar bone.

What is the biological width around implant?

The biological width around implant is a 3-4mm distance from the top of the peri-implant mucosa to the first bone-to-implant contact or the stabilized top of the adjacent bone, consisting of sulcular epithelium, junctional epithelium and fibrous connective tissue between the epithelium and the first bone-to-implant …

What is the difference between NUG and NUP?

NUG is an infection limited to the gingiva whereas NUP also involves the attachment apparatus. Predisposing factors may include immune dysfunction, poor oral hygiene, cigarette smoking and emotional stress. NUG and NUP might possibly be different stages of the same infection.

What causes nup?

The causative organisms are mostly anaerobic bacteria, particularly Fusobacteriota and spirochete species. Predisposing factors include poor oral hygiene, smoking, poor nutrition, psychological stress, and a weakened immune system. When the attachments of the teeth to the bone are involved, the term NUP is used.

Is NUP painful?

The main features of NUG are painful, bleeding gums and ulceration and necrosis of the interdental papilla. There may also be intra-oral halitosis, cervical lymphadenitis (swollen lymph nodes in the neck) and malaise. Treatment of the acute disease is by debridement and antibiotics, usually metronidazole.

How do you treat a nup?

Gingivectomy and/or gingivoplasty procedures may be helpful for treatment of superficial craters; periodontal flap surgery, or even regenerative surgery, is more suitable options for deep craters or for NUP.

What is the meaning of NUG?

A piece of marijuana
nug (plural nugs) (slang) A piece of marijuana.

Who are the nugs?

Nug is a term cannabis consumers typically use to describe buds of high-quality cannabis. The opposite of nug is “schwag,” or low-quality cannabis. Nugs make up the larger colas on the cannabis plant and have a relative density of trichomes far greater than leaves and stems or stalks.

What is a pinner?

Definition of pinner 1 : a woman’s cap with long lappets worn in the 17th and 18th centuries.
