"Established in 1983, SCDL continues to offer incredible value for money across all our product ranges - including implants, splints, anti-snoring devices and metal restorations, as well as the latest in ceramics, e.g Ceramage and eMax CAD."
IPS e.max offers the possibility to fabricate the ultimate aesthetic all-ceramic crowns. All crowns utilise a lithium disilicate framework ceramic and are either stained (monolithic design) or layered with a fluorapatite layering ceramic which permit the fabrication of restorations that demonstrate aesthetic properties similar to those of natural teeth..
IPS e.max Press is indicated for inlays, anterior and posterior crowns and 3-unit bridges having one pontic and not extending past the 2nd premolar.
IPS e.max CAD ( available in March 2011). The ceramic is milled in a "soft" intermediate state in which it exhibits its characteristic, unusual bluish colour. In this state, the material can be manually adjusted or cut back in a few quick and easy steps and the fit can be checked.
Subsequently, the material is easily and quickly crystallized at approximately 850 °C / 1,562 °F (20-30 minutes). In this process, IPS e.max CAD acquires its final strength of 360 MPa and the desired aesthetic properties, such as tooth shade, translucency and brightness.
IPS e.max CAD blocks are available in three levels of translucency and in two sizes. The LT and HT blocks for full-contour restorations are provided in 16 A-D shades and four Bleach BL shades. The MO blocks for the layering technique are available in group shades.
IPS e.Max Zir Press combines the benefits of a milled zirconia base with the beauty of the pressed fluorapatite glass ceramic. Ideal for inlays where more strength is required and can be cemented rather than bonded to minimise sensitivity.

Non-vital abutments disrupt the aesthetic outcome of some all-ceramic materials. When preparing multiple crown units in the anterior mandible or maxilla, select one material for all abutments (vital or non-vital) which will adequately mask the darkest shade. Do not mix all ceramic materials or rely on opaquers in the luting agent.
Since 1989, Procera Alumina has given dental professionals the ability to confidently restore teeth with natural appearing, metal free restorations, even in medium load-bearing applications.
The Procera Alumina restoration consists of two levels of advanced technology: a high strength aluminum oxide ceramic core and translucent veneering porcelain. The Procera Alumina coping is made of densely sintered pure aluminum oxide and is semi-translucent; this provides the veneering porcelain with a natural warm dentine-coloured core to establish a natural shade blend without opacity.
Clinical Preparation: Conventional methods are used to prepare the tooth (1.2 mm-1.5 mm chamfer or rounded shoulder with rounded internal line angles). Procera scanning and coping design: The die of the prepared tooth is scanned in the Procera Scanner, which transfers the information to a PC data file. The scanner uses a sapphire ball tip that reads the die shape by circular scanning, describing the tooth using approximately 20,000-40,000 digitized reading points, depending on the size and shape of the preparation. After scanning, the SCDL technician defines the finish line with extreme precision. The final design enhancements of the coping; the desired shape, its overall thickness, the precise angle of emergence and any final margin refinements are then completed. This digital information is then emailed to the Procera production facility.
Procera coping fabrication: At the work station, a die model is precision milled by a computer-controlled milling machine. High-purity aluminum oxide powder is thin pressed using very high pressure to produce the dense coping's inside surface. The outside of the coping is then milled to the desired design of the coping before the final high temperature (1,550 C) sintering process. The semi-translucent core is then completed using any necessary internal characterization and the naturally translucent layered (dentine, body and incisal) porcelain is added to complete the restoration.
Procera Alumina will mask metal posts and cores and discoloured abutments if adequate reduction has been provided. (Minimal 1.2mm)
A variety of end cutting burs wil help define the shoulder or chamfer required for all ceramic crowns.
