All Ceramic Restorations Properties • Superb Aesthetics Base layer thickness is uniform, but can be varied between 0.3 and 1.0mm. For crowns, a base layer thickness of 0.5mm is commonly used. Following sintering, base layers are coloured and translucent. This provides a natural background allowing the technician to re-create the depth of colour and translucency present in natural teeth. Techceram has now combined this base layer technology with Vita Alpha opalescent porcelain, which can be used either with the traditional or the new 3D shading system to achieve optimal aesthetics. • Clinically Proven Techceram restorations conform to the International Standard for Dental Ceramics (ISO 6872). The patented flame spray process used to manufacture Techceram base layers creates platelets which form a rough inner fitting surface, resulting in a high bond and biaxial flexural strength (300 MPa).   • Long Term Biocompatibility The flame spray process is unique in that it produces base layers which do not shrink during sintering. This, combined with properties of colour and translucency, allows the alumina base layer to be trimmed such that it extends virtually up to the marginal edge. These factors ensure highly accurate overall and marginal fit which aids the long term biocompatibility of the restoration.

Traditional build-up techniques are used to produce Techceram restorations, consequently trial fits may be conducted if required, prior to completion of the final restoration.     • Clinically Proven Tooth preparation must follow the recommended procedure in order to create the correct design of substructure with rounded edges and defined margins to ensure long term function. Techceram has now been in clinical use for over ten years and has proven to be an effective solution for restorations such as crowns, onlays, inlays and veneers. Correct Tooth Preparation    • Long Term Biocompatibility It is important that restorations are in harmony with the body tissues with which they interface. In general, the population is retaining their dentition to an older age, therefore biocompatibility is an increasingly important consideration. Metal alloy base layers have traditionally been used to reinforce porcelains to produce porcelain bonded crowns. Certain patients are however allergic to different types of metallic elements, most notably nickel. Nickel Sensitivity   Reaction to metallic elements can also lead to gingival recession over a number of years, revealing the "classic" grey marginal area.   Metal Bonded Restorations   Techceram restorations are of all-ceramic construction and display highly accurate overall and marginal fit. This aids close gingival adaptation which is important in the maintenance of healthy gums. Techceram Restorations
