Crown lengthening is a surgical procedure performed by a dentist, or more frequently a periodontist, where more tooth is exposed by removing some of the gingival margin (gum) and supporting bone. [1] Crown lengthening can also be achieved orthodontically (using braces) by extruding the tooth.
Crown lengthening is a technique for increasing crown height of teeth by flap surgery with or without bone surgery. [3] There are two main types: Aesthetic crown lengthening which is performed when a "gummy" smile is an issue for the patient [3] Functional crown lengthening is used to make an unrestorable tooth restorable.
Crown-to-root-ratio is the ratio of the length of the part of a tooth that appears above the alveolar bone versus what lies below it. [1] It is an important consideration in the diagnosis, treatment planning and restoration of teeth , one that hopefully guides the plan of treatment to the proper end result.
Dental implant, 3D illustration. A dental implant (also known as an endosseous implant or fixture) is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor.
In dentistry, a crown or a dental cap is a type of dental restoration that completely caps or encircles a tooth or dental implant. A crown may be needed when a large dental cavity threatens the health of a tooth. Some dentists will also finish root canal treatment by covering the exposed tooth with a crown.
Scaling and root planing, also known as conventional periodontal therapy, non-surgical periodontal therapy or deep cleaning, is a procedure involving removal of dental plaque and calculus (scaling or debridement) and then smoothing, or planing, of the (exposed) surfaces of the roots, removing cementum or dentine that is impregnated with calculus, toxins, or microorganisms, [1] the agents that ...
A common scenario of dental treatment causing aggravation of tooth mobility is with a new filling or crown which is a fraction of a millimetre too prominent in the bite, which after a few days causes periodontal pain in that tooth and/or the opposing tooth. [30] Orthodontic treatment can cause increased tooth mobility as well.
The implant stability quotient (ISQ) is the value on a scale that indicates the level of stability and osseointegration in dental implants. The scale ranges from 1 to 100, with higher values indicating greater stability. The acceptable stability range lies between 55 and 85 ISQ. [1] ISQ values are obtained using resonance frequency analysis (RFA).
