The Procera (one of the first of a Metal free type) process utilizes a computer-aided design (CAD) system. Your die is scanned, a digital file is created, and then the high-strength coping is created from that file. Advantages:
Estimated Cost Approx. Rs. 13,000 – 14,000 per Crown (for both types mentioned below)
Procera comes in two kinds of copings below the Ceramic, both metal-free though:
Procera (Alumina) is composed of a densely sintered high-purity aluminum oxide coping that is manufactured using CAD/CAM technology. The core has the ability to transmit light without being transparent. The secret behind Procera is its unique combination of strength and beauty. Extremely low fracture rates have been reported and the restorations serve for many years. More and more patients are asking for restorations made of material not containing metal or other alloys. It is made of a bio-compatible material (comparable to Titanium) which minimizes the risk of allergic reactions.
Strength no longer has to be compromised to achieve extreme esthetics. Procera Zirconia, made of Yttria Stabilized Zirconium (YZ) has substantial advantages compared to other dental materials: mechanical resistance, biocompatibility and fracture toughness two times greater than Alumina. The Flexural Strength of Zirconia restorations range from 900 to 1400 MPA. Conventional precious metal ceramics restorations are at 800 MPA or less. Metal ceramics cannot compete with the esthetics of Procera Zirconia. It is capable of being placed anywhere in the mouth and can accommodate 3 - 4 unit bridges. Procera Zirconia restorations can be inserted using conventional cementing techniques. Bonding is not required.
