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.

How are biological width violations corrected?
Biologic width violations can be corrected by either surgically removing bone away from proximity to the restoration margin, or orthodontically extruding the tooth and thus moving the margin away from the bone.
What is the significance of the biologic width of a tooth?
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 makes up biologic width?
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 is the new term for biological width?
The term periodontal phenotype replaced the periodontal biotype and supracrestal attachment is the new term replacing the biological width.
How many mm is biological width?
The biologic width is unique to each patient and will typically vary from about 0.75-4.3 mm. Based on the paper by Gargiulo written in 1961, the mean biologic width was 2.04 mm.
How do you measure biological width clinically?
What is bone sounding dental?
BIOLOGIC WIDTH In order to operationally define biologic. width, Kois suggested that the restorative. dentist must determine the total distance. from the gingival crest to the alveolar crest. This procedure is termed bone sounding.
What is Ante’s law?
Ante’s law states that “the total periodontal membrane area of the abutment teeth must equal or exceed that of the teeth to be replaced.”1 For more than 80 years, this law has been taught in standard textbooks of prosthodontics as an important condition influencing FDP design.
How long is a biologic width?
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.
What is the most effective antimicrobial therapy available to reduce plaque and gingivitis?
Of all the products included here, chlorhexidine appears to be the most effective agent for reduction of both plaque and gingivitis, with short-term reductions averaging 60% (29).
What is bone sounding in perio?
The process of probing anaesthetized tissue with a periodontal probe to establish the level of the underlying alveolar bone.
What is aggressive periodontitis?
Abstract. Aggressive periodontitis is a destructive disease characterized by the following: the involvement of multiple teeth with a distinctive pattern of periodontal tissue loss; a high rate of disease progression; an early age of onset; and the absence of systemic diseases.
How do you get a free gum graft?
- Step 1: Preparing the recipient site.
- Step 2: Harvesting the free gingival graft from palate.
- Step 3: Preparation and placement of fibrin-fibronectin sealing system (Tissucol®/Tisseel) on the root surface.
- Step 4: Placement of free gingival graft on the recipient bed coated with Tissucol.
What is necrotizing periodontal disease?
Necrotizing periodontitis is a disease of tissue destruction of both soft tissue (gums) and hard tissue (alveolar bone). As a result of the disease, both soft and hard tissue defects can make oral hygiene difficult.
What is ferrule effect in dentistry?
What Is the Ferrule Effect? According to Colgate, this phrase “refers to the need to have several millimeters of sound tooth structure left above the bone (alveolar bone) to decrease the risk of a tooth fracturing after certain procedures that require a crown, such as a root canal.”
What is the average width of the marginal gingival?
[14] The width of attached gingiva varies in different areas of the mouth and have been given a range of 1–9 mm,[15] 1–4 mm,[16] 0–g5 mm. [17] In the present study, the range of the mean width of attached gingiva varied from 1 mm to 4 mm.
What is biological width in periodontology?
Biological width is defined as the dimension of soft tissue which is attached to the portion of the tooth coronal to the crest of alveolar bone. (Gargiulo et al 1961) Gargiulo et al described the dimensions and relationships of the dentogingival junction in humans.
Who gave the term biologic width?
Walter Cohen for first coining the term in 1962. This term was based on the work of Gargiulo et al. (1961), who described the dimensions and relationship of the dentogingival junction from measurements made from 30 human cadaver jaws but did not relate them to any clinical applications in dentistry.
What is a crown lengthening procedure?
Crown lengthening is a procedure that is designed to reshape your gums at the base of the affected tooth in order to expose more of the tooth’s surface; and, if deemed necessary, to adjust the tooth’s bone level so that the height or size of the visible portion of the tooth can be extended so that the new restoration …
What does Cal mean in dentistry?
Clinical attachment loss which is also known as CAL, is the presence of periodontal disease. Periodontal disease, or gum disease, is a set of inflammatory conditions which affect the tissues that surround the teeth.
What is Transgingival probing?
[2,7] Transgingival probing is the procedure in which tip of the probe makes direct contact with the bone when the probe is forced under local anesthesia through the gingiva.
How is clinical attachment loss determined?
- When recession of the gingival margin is present, the CAL is calculated by adding the probing depth to the gingival margin level.
- When the gingival margin is coronal to the CEJ, the CAL is calculated by subtracting the gingival margin level from the probing depth.
What is Maryland bridge in dentistry?
A Maryland bridge is also known as a resin-bonded fixed partial denture. Like a traditional bridge, it includes a floating tooth to replace the missing one, but it adheres to the adjacent teeth in a unique way.
What is Pontics?
Pontic is the artificial tooth in the fixed or removable partial dentures; that is, the suspended portion of the fixed partial denture (bridge) replacing the missing natural tooth or teeth.[1] The pontic may be fabricated from cast metal or combination of metal and porcelain.[2] Designing a pontic is not simple; an …
