It is a type of crown that is formed by a tooth colored material. It is mainly used as a single unit in the anterior quadrant of the mouth. It is the weakest type of crown because the tooth colored materials are weaker and more brittle than metal. It can be divided into 2 types according to the material from which it is formed:
The acrylic jacket crown may be used as a temporary crown or for crowning a tooth of a patient under 18 years of age, until full eruption finishes to the tooth, and then a final crown (full veneer crown or porcelain jacket crown)

Metals used in crowns include gold alloy, other alloys (for example, palladium) or a base-metal alloy (for example, nickel or chromium). Compared with other crown types, less tooth structure needs to be removed with metal crowns, and tooth wear to opposing teeth is kept to a minimum. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down. Also, metal crowns rarely chip or break. The metallic color is the main drawback. Metal crowns are a good choice for out-of-sight molars.

Dental acrylic is something that you cannot skimp on. After all, acrylics are used for all sorts of procedures – from impressions to dentures. If you get the wrong acrylic, you can wind up with crowns and veneers that don’t fit right, repairs that don’t last, and dental work that looks unnatural.
At excludent.com, we have a variety of high-quality powder and paste acrylics, including:
Dental acrylic resin that can be used for impressions Dental acrylic veneer that goes over crowns to make them look more natural Dental acrylic that’s used for temporary procedures – like temporary crowns, veneers, and bridges Dental acrylic that’s used to repair dentures Dental acrylic that’s used to make retainers, bite guards, and mouthpieces

A temporary crown is a provisional, short term restoration used in dentistry. Usually the temporary crown is constructed from a chemical-cure composite, although alternative systems using aluminium crown forms are occasionally used by practitioners. The temporary material is shaped by the dentist to form a tooth shape that protects the prepared tooth, prevents damage to the periodontal tissues (gums) and disguises the prepared tooth to a degree until the final, definitive restoration can be made by a dental technician.
A temporary crown will usually be cemented in place with a soft temporary dental cement, such as Temp-Bond NE. This allows easy removal when fitting the definitve restoration. If a temporary crown becomes decemented, it is important that a dentist examine the patient as overeruption of the opposing teeth may prevent accurate fitting of the final crown.
Orthodontics, orthodontia, or orthodonture (from Greek orthos "straight or proper"; and odous "tooth") is the first specialty of dentistry that is concerned with the study and treatment of malocclusions (improper bites), which may be a result of tooth irregularity, disproportionate jaw relationships, or both. Orthodontic treatment can focus on dental displacement only, or can deal with the control and modification of facial growth. In the latter case it is better defined as "dentofacial orthopaedics". Orthodontic treatment can be carried out for purely aesthetic reasons with regards to improving the general appearance of patients' teeth. However, there are orthodontists who work on reconstructing the entire face rather than focusing exclusively on teeth.
