If a temporary crown becomes de-cemented, it is important that a dentist examine the patient as overeruption of the opposing teeth may prevent accurate fitting of the final crown. [8] If a dentist cannot be seen in a timely manner, the temporary crown may be re-cemented by applying temporary cement to the temporary crown.
Temporary crowns can either be direct, if constructed by the dentist in the clinic, or indirect if they are made off-site, usually in a dental laboratory. Generally direct temporary crowns tend to be for short-term use. Where medium-term or long-term temporisation is required, the use of indirect temporary crowns should be considered. [10]
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.
Zinc phosphate was the very first dental cement to appear on the dental marketplace and is seen as the “standard” for other dental cements to be compared to. The many uses of this cement include permanent cementation of crowns, orthodontic appliances, intraoral splints, inlays, post systems, and fixed partial dentures.
Provisional (or temporary) luting agents are used specifically for inter-appointment fixation of temporary restorations, prior to cementation of a permanent restoration. [20] It is mainly provisional crowns and bridges (fixed partial dentures) that are cemented with eugenol-containing temporary cements, but sometimes they may be used for ...
The diagnosis of toothache can be challenging, [35]: 80, 81 not only because the list of potential causes is extensive, but also because dental pain may be extremely variable, [44]: 975 and pain can be referred to and from the teeth. Dental pain can simulate virtually any facial pain syndrome. [44]
After the prefabricated post is properly cemented into the post space, a core material, such as dental composite, can be packed around the cemented post. After the material has been cured or has had a chance to set and properly formed into a crown preparation, an impression can be taken for the fabrication of a prosthetic crown. [9]
Dental porcelain (also known as dental ceramic) is a dental material used by dental technicians to create biocompatible lifelike dental restorations, such as crowns, bridges, and veneers. Evidence suggests they are an effective material as they are biocompatible , aesthetic , insoluble and have a hardness of 7 on the Mohs scale .
