ADVANTAGES
- Natural appearance and vitality
- Superior biocompatibilty
- Outstanding marginal accuracy
- Eliminates gray margins
- Extreme bond strength
- Proven to reduce plaque by 71%*
- No special chairside requirements
Gold is the proven standard for crown and bridge and Captek is the superior process for esthetics when it comes to PFM restorations. It has a deeper, richer gold color that blends with natural teeth without the harsh black lines assoicated with porcelain fused to base metals. Captek is also clinically proven to reduce plaque and the growth of harmful bacteria that may cause gum disease by 71%!* Because of Captek's unique composite structure and stress-free characteristics, the material itself is incredibly strong, with porcelain bond strengths that exceed those of traditional cast alloys! No special preparation or bonding techniques are required with Captek... saving valuable chair time during preparation and placement.
*When compared with natural teeth
Captek Material Properties
A Captek coping is a high noble yellow gold composite alloy that has an overall composition of about 88.2% gold, 9.0% platinum group metals (including 4.0% pure platinum) and 2.8% silver.
The Benefits Of Captek
NATURAL ESTHETICS The oxide-free gold color of the Captek coping produces an excellent background for porcelain application. The warm gold simulates the internal color that the pulp produces in the tooth, producing life-like shades without opacity. And because Captek requires only a thin layer of opaque, the unpleasant bright, high-value appearance of thicker opaque layers often seen at ceramometal crown margins is eliminated.
MINIMAL THICKNESS Reduced-thickness Captek copings and thin opaque layers help to prevent over contouring of the porcelain and enables normal emergence profile with conservative tooth reduction.
ELIMINATION OF DARK OR DISCOLORED MARGINS Your patients will appreciate the outstanding color matches and the elimination of graying at the margins.
PRECISION FIT Captek is formed directly on the die producing an excellent fit (about 14.5-17.5 microns) and a significantly smaller marginal opening than conventional porcelain fused to metal restorations.
MAXIMUM STRENGTH Load bearing capacity of Captek crowns is approximately 75 Mpa. The value for bridges is approximately 210 Mpa, which is equivalent to conventional porcelain fused to metal restorations. Additionally, Boston University research suggests that ceramic shear bond strength of Captek is at least equal to that of conventional ceramometal crowns and that they have a high resistance to impact fracture.
BIOCOMPATIBLE Clinicians have observed that tooth surfaces restored with Captek appear relatively plaque free and were associated with more healthy periodontal tissue. Captek metal surfaces appear to support approximately 1/10 the number of bacteria as natural teeth and may be a preferred surface in restoring abutments with periodontal disease affliction.
PREPARATION/CEMENTATION No bonding or aggressive preparations, just the standard PFM prep and cementation. Any type of tooth preparation can be used. This would include knife-edge, chamfer, bevel and shoulder preparations for metal or porcelain margins.
INDICATIONS Captek is indicated for anterior and posterior single crowns and multiple unit bridgework, implant cemented single and multiple unit restorations and selected inlay/onlay restorations.
SHADE SELECTION Select shade with a Vita Lumin Shade Guide or Vita 3D-Master Shade Guide.
IMPRESSION Preferably a polyether or polysiloxane material.
FINISHING/POLISHING Captek veneered with high-fusing porcelain – use conventional finishing polishing procedures. Captek veneered with low-fusing, low-abrasion porcelain use a medium/coarse grit diamond with a small amount of water spray (w/high-speed handpiece) for adjustments. To polish, first use a pre-polisher (gray wheels and points) and finish with porcelain polishing wheel or point (Dialite, Brasseler USA) with optional diamond polishing paste. |
