Dentistry - Dental furnace - Part 2: Test method for evaluation of furnace programme via firing glaze (ISO 13078-2:2016)

ISO 13078-2:2016 determines a degree of firing to be implemented by the user. It represents a test method for adapting the firing program of a dental furnace by determining the degree of firing of fired test specimens for a dental ceramic.
The test method is suitable for powdered dental ceramics according to ISO 6872, Type I.
The test method enables monitoring of the temperature control in the dental furnace by evaluating the firing degree of a dental ceramic. The test method is also suitable for evaluating the reproducibility of the firings in a dental furnace or for comparing several dental furnaces.

Médecine bucco-dentaire - Four dentaire - Partie 2: Méthode d'essai pour l'évaluation du programme de cuisson d'un four via une cuisson de glaçure (ISO 13078-2:2016)

ISO 13078-2:2016 détermine un degré de cuisson à mettre en ?uvre par l'utilisateur. Il constitue une méthode d'essai pour l'adaptation du programme de cuisson d'un four dentaire en déterminant le degré de cuisson d'éprouvettes cuites pour une céramique dentaire.
Cette méthode d'essai convient à des céramiques dentaires en poudre conformément à l'ISO 6872, Type I.
Cette méthode d'essai permet de vérifier le contrôle de la température dans le four dentaire en évaluant le degré de cuisson d'une céramique dentaire. La méthode d'essai convient également à l'évaluation de la reproductibilité des cuissons dans un four dentaire ou à la comparaison de plusieurs fours dentaires.

Zobozdravstvo - Dentalne peči - 2. del: Preskusna metoda za vrednotenje programa peči s stopnjo vžiga (ISO 13078-2:2016)

Ta mednarodni standard določa stopnjo vžiga, ki jo mora uvesti uporabnik. Predstavlja preskusno metodo za prilagoditev programa vžiga dentalne peči z določitvijo stopnje vžiga žganih preskušancev za dentalno keramiko. Preskusna metoda je primerna za dentalno keramiko v prahu v skladu s standardom ISO 6872, vrsta I. Preskusna metoda omogoča spremljanje nadzora temperature v dentalni peči z vrednotenjem stopnje vžiga dentalne keramike. Preskusna metoda je primerna tudi za vrednotenje ponovljivosti vžigov v dentalni peči ali primerjavo različnih dentalnih peči.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

Introduction

Dental furnaces are suitable for the manufacturing of metal-ceramic and partly also all-ceramic

restorations for use in dentistry. Dental furnaces are particularly used for firing or sintering,

respectively, of dental opaques, dentine and enamel materials to the respective compatible substructure

materials. According to the current state of the art, the temperature of this process lies between 600 °C

and 1 000 °C.

The different calibration processes applied by the manufacturers of dental furnaces as well as the

varying construction types of the dental furnaces currently on the market influence the firing result.

Despite the fact that different dental furnaces can have identical digital external displays, different

results regarding the degree of firing can be identified when processing the same ceramics under

otherwise similar conditions.

A different degree of firing not only causes differences that can be judged directly by the human eye

(e.g. colour and transparency), but also deviations that cannot be detected by the eye. These are, for

instance, the linear coefficient of thermal expansion, the bonding strength, the strength values and the

acid solubility. Such changes may result in clinical failures (e.g. fractures) as well as changed aesthetics

of the dental ceramic restoration.
