Shofu Vintage Halo Porcelain System
This document provides instructions and technical information for the Shofu Vintage Halo porcelain system, including the Red Shift and Value Plus lines.
Natural Color Concept
The Vintage Halo system is based on a natural color concept, utilizing a three-dimensional color space (L*a*b*) to define colors by Value (clarity), Hue (color tone), and Chroma (saturation/intensity).
Color Space Representation
Diagram 1: A representation of a 3D color space, illustrating the relationship between different color components.
Diagram 2: A cylindrical model showing color value (lightness) on the vertical axis and hue (color tone) on the circular axis. Arrows indicate the progression of hues.
Diagram 3: An elliptical representation of natural tooth color distribution, divided into three zones based on clarity (Value). This illustrates that natural tooth colors are not uniformly distributed and are more concentrated in certain value ranges.
Diagram 4: An arrangement of ceramic colors by shade codes (e.g., VR1, A1, B1, C1, D1) within defined color zones, showing their placement within the natural color distribution.

Color Selection and Application
The Shofu Vintage Halo system offers two main lines: Red Shift and Value Plus, designed to accurately reproduce natural tooth colors.
Porcelana VINTAGE HALO Red Shift
Color Selection:
The Vintage Halo color guides are used with GUMY® gingival color samples to simulate the natural tooth environment. Selecting teeth colors without GUMY® can lead to a contrast effect, making restorations appear more yellowish and lacking chromatic intensity. The Red Shift colors are positioned in the reddish range of group A and Value Plus A. Red Shift colors A1-A4 are designated R1-R4, and Value Plus variants VA1-VA4 are designated VR1-VR4. Color selection is performed using the Vintage Halo Red Shift guide in conjunction with the GUMY® sample that matches the patient's gingiva.
Utilization:
Red Shift powders are used according to the basic stratification system of Vintage Halo ceramics. The incisal opal layer should extend to the cervical area. Reproduction involves using Opáquer, Opaque Dentin, Dentin, and Incisal Opalescent powders. Red Shift powders are complementary components, and users should refer to the Vintage Halo Basic instructions. For Red Shift, both powder and paste opaquers are available. Apply the selected opaquer to the prepared metal structure, ensuring optimal coverage after the second application. Firing parameters should follow the firing table. Special attention is required for preheating and firing temperatures for paste opaquer to ensure complete calcination of organic components.
Opaque Dentin:
Opaque dentin is used to correct excessive opaqueness in the cervical, interproximal, or thin wall areas, providing a natural reflection and clarity. Red Shift opaque dentins are prepared individually, mixed according to the color table using OD-A1 to OD-A4 powders and Red Dark modifiers.
Opaque Dentin / Value Plus:
Opaque dentin is not required for Value Plus Red Shift colors. The ultrafine particles of Value Plus dentin powders provide superior brightness, clarity, and chromatic density compared to conventional Vintage Halo dentin powders. Value Plus dentin powders are applied directly over fired opaquer and stratified according to anatomical dentin form.
Dentin Powders:
Red Shift (Body) dentin powders are used to model the anatomical form, ensuring exact configuration, orientation, and dimension of the dentin body.
Incisal Powders (Opal/Standard):
Vintage Halo Opal incisal powders are used for optimal natural light transmission in the incisal area, mimicking dental enamel. For restorations with a metallic palatal surface up to the incisal edge, Vintage Halo Standard incisal powders combined with a transparent ceramic layer are recommended. Stratification is completed with desired incisal or transparent powders, adjusting firing parameters as per the table.
After Firing:
The fired restoration should have a slight matte finish. Any subsequent corrections can be made directly without abrasive instruments. Adding incisal opal or standard ceramic is often sufficient. After final surface finishing, a glazing firing is performed.
Porcelana VINTAGE HALO Value Plus
Color Selection:
Color selection for natural teeth is done using the Vintage Halo Basic guide with GUMY® samples. Younger patients' teeth may appear lighter than Basic guide samples, making a guide with increased clarity (Value Plus) useful. Based on Makoto Yamamoto's analysis, the Vintage Halo Value Plus guide includes A and B group colors with enhanced clarity. Value Plus colors A1-A4 are designated VA1-VA4, and B1-B4 are designated VB1-VB4. Selection is made using the Vintage Halo Value Plus guide with the GUMY® sample matching the patient's gingiva.
Utilization:
Value Plus powders are easy to use and follow the basic stratification system of Vintage Halo ceramics (refer to Vintage Halo Basic instructions). They are used with Opáquer, Dentin, and Incisal Opalescent powders. Opaque dentin is not required due to the superior brightness and chromatic density of Value Plus dentin powders.
Opaquer (Paste/Powder):
For Value Plus colors, conventional or paste opaquer from groups A or B is used. For example, to reproduce color VA2, A2O opaquer is applied. Consult the color table for correlations. Apply selected opaquer to the prepared metal structure for optimal coverage after the second application. Firing parameters should follow the table. Special attention is needed for paste opaquer preheating and firing temperatures.
VOP (Value Plus Opaque):
VOP is an ultrafine opaquer modifier to increase the clarity value of Vintage Halo opaque powders. Add VOP to A10 or B1O opaquers in a 1:3 ratio for colors lighter than VA1 or VB1. VOP is available only in powder form and should not be added to paste opaquers.
Dentin Powders:
Value Plus dentin powders (Body) are used to model the anatomical form, ensuring exact configuration, orientation, and dimension. They are applied directly over fired opaquer and stratified according to anatomical dentin form.
VDL (Value Plus Diluent):
VDL is an ultrafine dentin modifier to increase the clarity value of Vintage Halo or Value Plus dentin powders. It is used similarly to VOP. For colors lighter than VA1 or VB1, add VDL to VA1B or VB1B dentin powders in a 1:3 ratio.
Incisal Powders (Opal/Standard):
Similar to Red Shift, Opal incisal powders are used for optimal light transmission in the incisal area. Standard incisal powders are used for metal-ceramic restorations with a metallic palatal surface. Stratification is completed with desired incisal or transparent powders, adjusting firing parameters as per the table.
After Firing:
The fired restoration should have a slight matte finish. Corrections can be made directly. Glazing firing is performed after final surface finishing.
