GC Initial®
Complete Ceramic System


GC Initial can create metal-ceramic restorations all the way to full-ceramic. This product consists of six ceramics in one integrated product line with one color system. No longer does the ceramist have to spend valuable time learning to use a myriad of different ceramics from an array of manufacturers to create the variety of restorations which may be needed to complete a case. Each GC Initial ceramic is adapted to meet the needs of its particular fabrication process and framework, such as its coefficient of thermal expansion (or CTE). Stress cracks and fractures are therefore avoided, which assures strong bonding, adhesion and retention. With GC Initial, you need to master only one layering technique and one shade system. The Initial ceramic system allows you to use the identical processing method for all components using a single shade system. You don't have to re-adjust to other unaccustomed layering techniques or layering systems. GC Initial gives you more essential time to be creative. It doesn’t matter if you are working with full ceramic, metal-based, titanium or zirconium oxide or aluminum oxide frameworks; this system has its own components when low-fusing technology or the ceramic pressing techniques are used. GC Initial is also ideally suited for use with the proven sintering technique. GC Initial MC is used for the first coating on investment dies. Your work can then be completed easily and efficiently with the "low-fusing" component, GC Initial LF.
To extend the unparalleled shading system of GC Initial, we've introduced GC Initial Bleach Shades with a unique color set that allows for matching even the lightest tooth shades. They are available as separate sets, each containing different components. When adding them together, you can increasingly create aesthetic restorations.
With the same shading system and build-up technique, GC Initial requires a short-learning curve and can easily be adapted by high volume labs or tooth design boutiques, regardless of the substructure or framework. This product was developed for maximum technique tolerance, which is very forgiving and has extremely low shrinkage.

"As a trained Dental Technician, working with my hands and technical skills has always come easy to me, far easier than all the artistic skills required of a world class dental ceramist. I have had to devote countless hours, too many of them frustrating, to improve on the artistic side of my ceramic work. GC is such a true system - it has taken the guesswork out of my build-ups and has elevated my work to a whole new level. GC has inspired me and taken my craft to a whole new level!"

"For the first time, with these innovative products, we can effortlessly adjust our porcelain technique concepts and, in the process, get maximum quality and profit. Fellow Technicians: I love these products!"

"I initially began using GC Initial MC for high-end cosmetic cases where the doctor chose to go with a conventional PFM. I had no idea that it would increase my production and improve the accuracy of my ceramists and myself. The GC Initial MC ceramic layering technique is laid out extremely well and I can really appreciate the depth of this kit. My doctors immediately noticed the difference in esthetics while I watched production increase. I was so thrilled with this product that I have since tried GC FUJIROCK, GC Initial IQ Press, and the entire line of GC Initial MC ceramics with tremendous success. I highly recommend this ceramic to anyone looking to improve the quality and production of their laboratory."

"GC Initial Ti falls in line with the high standards GC has with all of their porcelain. My clients and their patients have raved about its beauty and consistency. The porcelain bonded to titanium crowns has improved the traditional PFM. Titanium has reduced the costs and GC has made it stunning."

"Introducing titanium into your lab is easy with GC's Initial Ti because it has all the vitality, depth, translucency and life-like beauty we are used to seeing in GC's other porcelains, with the same handling characteristics. For us, the decision was easy."
