FAQ: What Is Biological Width?

The natural seal that develops around both, protecting the alveolar bone from infection and disease, is known as the biologic width.[4] The biological width is defined as the dimension of the soft tissue, which is attached to the portion of the tooth coronal to the crest of the alveolar bone.

What is biologic width of tooth?

Biologic width is the distance that is established by the junctional epithelium and connective tissue attachment to the root surface of a tooth. This can also be described as the height between the deepest point of the gingival sulcus and the crest of the alveolar bone.

Why is biologic width important?

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 a the length of the biologic width of tissue on a healthy Periodontium?

In general, its length is 3 mm from the bone crest to the cement-enamel junction in healthy teeth or until the end of the preparation or the margin of restoration in restored teeth [10].

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 most effective antimicrobial therapy available to reduce plaque and gingivitis?

By eliminating harmful bacteria from the mouth with antibiotics, periodontal symptoms such as bleeding gums and loose teeth can be eliminated without surgical intervention. Antiseptic mouthwashes are the most common antimicrobial treatment.

What is fenestration and dehiscence?

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]

What is the periodontal space?

The Periodontal Ligament (PDL) can be defined as a fibrous joint that anchors the root of the tooth to the alveolar bone socket. Made of fibrous connective tissue, it holds the tooth in sprung suspension enabling the tooth to take on the mechanical pressure during function.

Where should crown margins be placed?

The margins for crowns should be placed supragingivally—that is to say, they should be placed at or above the gum line. If they’re placed slightly below the gumline, they shouldn’t go more than 0.5mm beneath the surface.

What happens when you violate biological width?

Around teeth, the most common response to a biologic width violation is gingival inflammation, a significant problem on anterior restorations. The importance of biologic width to surgery relates to its reformation following surgical intervention.

What is bone sounding dental?

The process of probing anaesthetized tissue with a periodontal probe to establish the level of the underlying alveolar bone. From: bone sounding in A Dictionary of Dentistry » Subjects: Medicine and health — Dentistry.

What is a good crown root ratio?

In considering the crown-root ratio as a prognostic tool, a ratio of 1:2 is considered ideal, whereas for teeth used as abutments for a fixed partial denture, a ratio of 2:3 or 1:1.5 is desirable. Nevertheless, a crown-root ratio of 1:1 is considered to be minimal (20).

What type of bacteria causes periodontal disease?

The bacteria associated with periodontal diseases are predominantly gram-negative anaerobic bacteria and may include A. actinomycetemcomitans, P. gingivalis, P.

What is the width of attached gingiva?

The width of attached gingiva is the distance between the mucogingival junction to projection of the external surface of the bottom of the sulcus or the periodontal pocket.

How do you do crown lengthening?

The procedure involves removing soft tissue and sometimes bone to increase the amount of tooth that is visible. A periodontist may perform the procedure on one tooth, several teeth, or the entire gumline. Dentists may perform crown lengthening procedures to: address cosmetic concerns.
