Used in case of bruxism or dental malocclusion, the dental splint is a cushion that is positioned between the arches and serves to cushion the shocks and rubbing due to the occlusion of the jaw.

There are two types of bite: soft and rigid.

• The soft bites are made of silicone and are used above all to attenuate the friction caused by bruxism, therefore by grinding of the teeth.
• The rigid bites are made of acrylic resin and can be used to help the arches to have a correct fit between the teeth.

The crystallization process of lithium disilicate occurs in two steps.

• In the first phase, the metasilicates precipitate and give the glass-ceramic characteristics such that it can be easily processed for extra and intraoral occlusal retouching.
• The second, definitive phase takes place after finishing at a temperature between 840-850 ° C. At these temperatures the metasilicate dissolves completely and the disilicate crystallizes ensuring the formation of a solid microstructure.

Firing by the union is used for dental veneers (veneering solutions) which involve the use of lithium disilicate glass-ceramic supported by zirconium oxide.

The milling of the two components takes place separately and then they are joined later using a fusion-glass ceramic.

The surgical guides are clinical aids used to correctly perform the positioning of the final implant.

These are transparent resin masks that once placed in the oral cavity allow the exact insertion of the surgical screw, both in terms of location and depth.

Lithium disilicate is a glass-ceramic with lithium crystals that combines good mechanical strength with an excellent level of aesthetics.

It consists of 70% by volume of needle-shaped crystals in a glassy matrix. It can be both milled and pressed.

It can reach a strength of 450 MPa if milled or 360 MPa if pressed.

It is a very versatile material and can be used for anterior and posterior restorations, such as frontal veneers (veneers), minimally invasive inlays and onlays, partial and total crowns, superstructures on implants, three-unit bridges.

Dental veneers (veneers) are ceramic casings applied to the external tooth surface to improve its aesthetics.

STL is a file format native to the stereolithography CAD software created by 3D Systems. STL has several backronyms such as “Standard Triangle Language” and “Standard Tessellation Language”.

The STL format specifies both ASCII and binary representations.

To this system belong all the crystals whose internal structure is based on the shape of the parallelogram.

‘Monoclinic’ in this case means ‘with only one inclined angle’. Monoclinic crystals, therefore, have an oblique angle.

It is the  typical shape of Zirconia before sintering.

It includes all crystals with a rectangular internal structure.

The name Tetragonal comes from the Greek tetragon, and it means quadrangular. Tetragonal minerals are normally made up of rectangular-faced crystals, sometimes vaguely delimited, other times well defined.

It is the final shape of the Zirconia after sintering.

Machining with the milling cutter in radial position in order to produce a highly precise cam shape

It can be made dry (zirconia) or wet (lithium disilicate).

The glaze can be in paste or powder, in the fluorescent or non-fluorescent variant.

The glaze is used to give the restoration shine.

The degree of gloss of the glazed surface is regulated by the consistency of the glaze and the amount of glaze applied, not by the firing temperature.

The inlay is an indirect filling, used when the healthy dental material is too little.

There are different types of inlay: inlay, onlay, overlay.

Inlays when applied within the dental surface.

Onlays when they partially cover the dental surface of the molars and premolars.

Overlay when fully covering the dental surface of the molars and premolars.

CAD (Computer-Aided Design) modeling is a virtual design process that allows the production of an STL file that can be used in different ways such as CAM milling, 3D printing, stereolithography, etc.

Monolithic restoration means restoration consisting of a single block.

Zirconium oxide (or zirconia) is the ceramic oxide of zirconium, characterized by the chemical formula ZrO2.

It is a polymorphic substance that is it can modify its crystalline structure while maintaining the original chemical composition.

At room temperature up to 1170 ° C, the crystal structure is monoclinic.

From 1170 ° C to 2370 ° C, the crystalline structure transforms into TETRAGONAL with a contraction that can reach up to 25%.

The tetragonal structure is the one used for zirconia prostheses.

PMMA, the short form of a polymethyl methacrylate, is a biocompatible resin used for long-lasting temporary restorations.

Polymerization is the process of hardening a material by passing a light.

The intraoral scanner is a 3D scanner, which collects information on the shape and size of dental arches (or on the position of dental implants) through the single emission of a light beam.

Sintering is a heat treatment that generates changes in the chemical structure of the material.

It is the process through which zirconium oxide passes from the monoclinic to the tetragonal shape.

Thanks to sintering, the prototype acquires the mechanical, chemical, and optical characteristics of Zirconia.

The technique to print parts and assemblies made of several materials with different mechanical and physical properties in a single unit.

Stereolithography is an addition process similar to 3D printing but in this case, the material is polymerized (hardened) in layers.

The material is in a liquid state and is polymerized by the passage of light, usually a laser.
