The System
The SNF PressCeram™ System has been developed by Swiss NF
Metals, Inc. to provide a ‘3-in-1’ crown & bridge
solution for today’s dental technician’s needs. The
system is multi-functional and can be used to produce restorations
using three techniques: Press-To-Metal (PTM), Pressed All-ceramic
and Porcelain-Fused-to-Metal (PFM). All of these techniques use
the same layering porcelain thus making it the ideal system to
successfully complete any combination case. The SNF PressCeram™
glass ceramic ingots are available in a complete variety of shades
so that shade selection can be simple and accurate.
SNF PressCeram™ Ingots
The ingots are a dual-phased leucite glass ceramic. The ingots
have a high density and low wear to opposing dentition. The ingots
can be used when utilizing the ‘Stain & Glaze Technique’,
the ‘Cut-back & Layering Technique’, or both.
The ingots are fluorescent and opalescent. The ingots are available
in 3 different levels of opacity: 30%, 50% and 70%. The ingots
are available in many shading systems: Vitapan® Classical
A-D shades, CT1-CT4 shade ranges for the veneering and inlay/onlay
technique, Monocast Staining Shades and Various Bleach Shades.
The ingots are available in 2g and 5g sizes.
The
following is a chart showing the ingots that are available within
the SNF PressCeram™ system.

Preparation Guidelines
Press-To-Metal
Use the Porcelain-Fused-to-Metal requirements to proceed with
the Pressed-To-Metal preparation guidelines. Shoulder or Heavy
Chamfer preparations should be used. Feathered edge preparations
are possible with PTM. However, a thicker anatomic wax build-up
is needed at the margin. Inlay and Onlay preparations need to
be at a 90° angle (box preparation). The dimensions need to
be at least 2mm in width by 2mm in length by 2mm in depth. Note:
Along with 360° porcelain margins, 180° labial porcelain
margin with 180° lingual metal margin is possible
All-Ceramic
Inlay: Minimum 2mm depth by 2mm width by 2mm length (otherwise
the material will be subject to failure!) Onlay: Same as Inlay,
with at least 2mm reduction in cusp area. Veneers: 0.8 –
1mm reduction. More reduction results in more translucency. Crowns:
1 – 2mm reduction with 360° chamfer on a 10-30°
angle. Note: Avoid using feature-edge preparations with all-ceramic
restorations.
Alloy
Selection for Press-To-Metal
Noble or Base alloys can be used for the Press-To-Metal technique.
IMPORTANT:
Coefficient of Thermal Expansion (CTE) is critical for the success
of SNF PressCeram™. Be sure that the metal that is being
used is ideally suited for the SNF PressCeram™ System.
The
ideal CTE for Press-To-Metal is 13.8 - 14.2 x 10-6
K-1 (25-500°C).
Ingot
Selection Chart
Please use the following Ingot Selection Guide to assist you when
selecting the best ingot for a specific restoration.
Cementation
Recommendations
Pressed-To-Metal:
Cement restoration as you would conventionally cement any Porcelain-Fused-to-Metal
restoration.
All-Ceramic:
Bonding Cementation is required for all-ceramic restorations.
DO NOT conventionally cement all-ceramic restorations. Any dual-cure
resin cement with minimal expansion in conjunction with a bonding
agent is recommended.

SNF
PressCeram™ as a PFM Porcelain
SNF PressCeram™ Porcelains can also be used as a PFM porcelain.
Use the porcelain for single restorations or bridges. This system
is ideal for combination cases because it uses the same porcelain
for all types of restorations.
Metals
with a CTE of 14.0 – 15.0 x 10-6 K-1
(25-500°C) can be used when building SNF PressCeram™
porcelain for conventional PFM crowns.
