Dental zirkonia – fra bunn til munn
Sammendrag
Sammendrag
Bruken av zirkonia som dentalt restaureringsmateriale har økt kraftig siden innføringen på 90-tallet. Økningen skyldes gjentatte endringer og forbedringer av materialet, samt utviklingen av CAD/CAM-teknologi til fremstilling av indirekte restaureringer. Zirkonia er bygget opp av krystaller med ulik struktur som har direkte sammenheng med materialegenskapene. Tilsetning av yttria påvirker mengdeforholdet av strukturene. Ved den laveste konsentrasjonen yttria er andelen tetragonal krystallstruktur høy, hvilket gir gunstige mekaniske egenskaper. Ved tilsetning av en større mengde yttria øker andelen kubisk struktur, noe som øker translucens, men reduserer styrke og seighet. Translucent zirkonia er egnet til monolittiske restaureringer blant annet av estetiske årsaker og for å unngå avskalling av porselen. Zirkonia benyttes til mange typer tann- og implantatrestaureringer, i dentale implantater og som kjeveortopediske brackets.

Abstract
Since the introduction of zirconia as a dental material in the 1990s, its application has increased due to improvements of the material and the development of CAD/CAM systems for the preparation of indirect restorations. The addition of yttria affects the proportion of crystal structures that make up the material and determine its properties. At low concentrations of yttria, zirconia consists predominantly of the tetragonal structure, which toughens the material. Increasing the yttria content decreases the fraction of the tetragonal structure in favour of the cubic structure, contributing to increased translucency. Translucent zirconia is suitable for monolithic restorations with an acceptable appearance. This lessens the need for veneering porcelains and eliminates the risk of chip-off fractures. Clinical applications of zirconia include tooth- and implant-supported restorations, dental implants and orthodontic brackets.
