His workings were then used by other dentists studying dental orthopaedics. His teachings became known as Roux Hypothesis, which Karl Haupl later expanded upon. The Monobloc was developed by Pierre Robin (surgeon) in 1902 and is considered to be one of the first functional appliances in Orthodontics. The Monobloc was a modification of ...
In fixed retainers, composite is usually placed to bond and to cover the wire, whilst ensuring no interference in the interdental space. Fixed retainers are used in situations where instability is more likely, such as severe rotations, periodontal disease and median diastemas. Occasionally the patient will require a removable retainer as well.
The traditional method for management of dental caries has evolved from the exclusive domain of techniques based on complete caries removal prior to tooth restoration. Norna Hall used pre-formed crowns and cemented over carious primary molars using a glass-ionomer luting cement, with no caries removal, tooth preparation, or local anaesthesia.
If porcelain is to be applied to the gold crown, an additional minimum of 1 mm of tooth structure needs to be removed to allow for a sufficient thickness of the porcelain to be applied, thus bringing the total tooth reduction to minimally 1.5 mm. For porcelain or ceramic crowns the amount of tooth reduction is 2 mm. For metal, it is 1 mm.
In the United States a smart retainer sensor is exclusively provided by orthodontists who have signed up to be providers, and should retail for around $100.

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. [1] A crown is typically bonded to the tooth by dental cement. They can be made from various materials, which are usually fabricated using indirect methods. Crowns are ...
The tooth could then be replaced with a dental implant. Alternatively, orthodontic extrusion can be used to achieve crown lengthening. Using brackets, light forces can be used to pull the tooth away from the gums within a few months. A fiberotomy is performed after crown lengthening and is easily performed by the general dentist.
