All Porcelain Restorations

In these days of patient awareness and a degree of uncertainty regarding various metals being placed in the mouth, it is not surprising that people are concerned with the long term effect different alloys will produce.

Allergic reactions to base metals, nickel, amalgam etc. are just a few that are raising question marks and forcing us to consider suitable alternatives to bonded crowns and bridges.

The following materials are totally metal free, and although there are certain limitations to each, their strength cannot be overstated if used and indications are correctly followed.

The secret behind Procera AllCeram is its unique combination of strength and beauty.  Over the last few years, new technology has given dental porcelain better properties.  Until now, however porcelain coated ceramic copings have been neither strong enough, nor durable enough for widespread use. Procera AllCeram is a coping made of extremely dense-sintered aluminium oxide.  The coping is produced in an industrial process known as Procera, which ensures optimal fit, high strength, non-porosity and has the ability to transmit light without being transparent.  Due to the strength of the core material, Procera AllCeram can be recommended anywhere in the mouth.

Scanning * Design * Production

The design of Procera AllCeram coping is developed at the laboratory using the Procera Scanner and the data collected is sent to Sweden for the construction of the Procera coping.  After completing the machining process, the finished coping is returned to the laboratory for porcelain veneering of the restoration.

Veneering

: Porcelain is built up on the Procera coping

Cementing: The Procera manufacturing process yields a uniform space between crown and tooth.  This gives an optimal fit to the tooth’s shape and enables the construction to be properly seated while providing enough space for cement.  The restoration is cemented with the material of your choice. i.e. zinc phosphate, glass ionomer or a dual cure bond. (avoid any cements with post set expansion)

Before treatment After treatment

Techceram all-ceramic restorations offer natural looking aesthetics for the most discerning of patients.  The coloured, translucent base layer provides a natural background allowing the technician to re-create the depth of colour and translucency present in natural teeth.  Techceram combines FLAME SPRAY TECHNOLOGY with Vita™ Alpha porcelain, which can be used either with the traditional or the new 3D shading system to provide optimal aesthetics. Once the coping has been fabricated the veneering technique is similar to that of Procera.

Likewise the cementation of Techceram is identical to that of Procera.

Cerpress SL

Experience the aesthetics of a new generation of pressable ceramics that can be used for crowns, veneers or inlays.  Cerpress SL is based on two-phase glass ceramic Lucite crystals embedded in a glass matrix.  In addition to the absorption, reflection and transmission of light, which primarily determine colour and transparency, light refraction plays a vital role in the perfect imitation of a tooth.  The crystal size and distribution of Cerpress SL ceramics is very similar to the morphology and microstructure of natural dentition, thereby closely imitating the optical effects.  Sensation SL low fusing porcelain is layered on the Cerpress coping due to the high content of Lucite and small crystal size provides increased strength and superior light reflection qualities.  Fluorescence is a major characteristic in creating a natural appearance.

Sensation SL has the perfect balance of fluorescent elements, which enables the restoration to duplicate natural dentition in all lighting conditions.  Sensation SL is wear compatible with natural dentition, meaning it will not abrade the opposing teeth, as do most high fusing porcelains.  It also offers excellent chair side polishablity.

Sinfony

Sinfony offers a concept for easy reproduction of the complete VITA classic colour system. Using the exactly co-ordinated 16 opaque and dentine materials allowing brilliant shade reproduction.  A good balance of transparency and opacity ensures exact shade reproduction even in thin veneers.  The enamel and transparent materials are ideal for customising ceramic like restorations with natural fluorescence and opalescence, creating a fascinating vitality and brilliance.  Sinfony has high plaque resistance, impressive physical properties, compressive and flexural strength, and impact and abrasion resistance and water absorption, properties, which justify calling SINFONY a new type of composite technology.  Consequently, the range of indications is wide

SINFONY is a material for a large number of indications:

Fixed crowns, telescopical and conical crowns, external attachments, bridges, adhesive bridges, implant superstructures, veneers, inlays and onlays, long-term temporary restorations and the customisation of artificial teeth made of acrylic.
