Bulletin Made In U.S.A. SATURN MA Dual-Light and Self-Cure Core Build-Up Material
CONTENTS
OUTSTANDING FEATURES OF THE MATERIAL
The restorative cures to great depths with light induced curing mechanism, without the necessity of mixing. When mixed with Paste Additive or Liquid Additive, the restorative sets fully irrespective of the thickness of the restoration or accessibility to light. Virtually unlimited working time in light-cure mode; convenient working time in self -(chemically) cured mode. Two shades: one contrasting for ease of distinguishing from tooth structure; the other natural for use under semi-transparent ceramics. Well balanced x-ray opacity permits easy distinguishing from tooth structure, as well as from pins and posts. Moldable, non-sticky, yet still has adhesive consistency. Allows for controlling consistency, wherever desirable, by adding either liquid or paste-type catalyst for dual-cure. Contains moderately hard filler for easier carving and shaping. Does not require refrigeration; long shelf life at ambient temperatures. Also suitable for cementing posts. Substantial chair-time savings. GENERAL INFORMATION
Saturn-M differs significantly from conventional restoratives as it was formulated to meet specific requirements, and provide features most desirable for core build-up materials. This includes a well balanced x-ray opacity, which allows the dentist to distinguish the material from both tooth structureand posts, carvability, outstanding depth of cure (to maximize the advantage of light-cure feature), and extended working time when cured in self-cure mode. All pertinent characteristics of the cured material exceed the requirements of the American Dental Association Specification No. 27, for Type I (lower grade) and Type II (higher grade) filling restoratives. The requirements for core build-up materials are not as demanding as for filling restoratives, as they are not directly exposed to mastification forces,and are less susceptible to chemical deterioration resulting from exposure to oral environment. The mechanical properties of Saturn-M are notably superior to that of the properties of glass ionomer type cements.

COMPARISON OF PROPERTIES OF CURED EAGLE WITH GLASS
IONOMER CEMENTS AND WITH THE REQUIREMENTS OF ADA SPECIFICATION NO.27 FOR COMPOSITE RESTORATIVES
APPLICATION TECHNIQUESSaturn-M may be used without pins or posts, or in conjunction with them, if their use is deemed desirable or necessary.The restorative may be applied directly onto the prepared tooth, using plastic or metal instruments, or by using transparent crown forms. LIGHT-CURE MODE ONLYWhen the thickness of the restoration is less than 4mm, or when the restorative is applied in more than one layer the Restorative Paste Natural or Contrast Shade may be used alone, ie., without mixing with the Paste Additive or Liquid Additive just apply and light-cure. Cure may be accomplished with any commercial dental curing light operating in a visible wavelength range. Depending on the desired depth of cure and light intensity, the necessary curing time may vary from 20 to 90 seconds. The tip of the light should be placed as close to the restoration as possible, and moved slowly around its periphery and over its top.
DUAL-CURE MODE For curing in thick layers, for cementing posts, or in situations where thinner consistency of the restorative is desired, the Restorative Paste should be mixed with Paste Additive, or Liquid Additive. The mixing with Paste Additive, or Liquid-Additive will result in triggering the self-cure mechanism while not interfering with the ability of the material to cure by light.

The clinician has the convenience of choice between liquid and paste type accelerators. The liquid form is preferred for cementing posts and in applications where the use of low viscosity material is indicated, because of perceived difficulties in placement, and/or filling narrow spaces. The paste-type accelerator is generally preferred in situations where the cure of large bulks of the material is involved. Its use allows the dentist to take advantage of the self-cure feature of the restorative while preserving its moldable consistency.MIXING PROCEDURE FOR DUAL CURE MODE
*The restorative/liquid ratio may vary giving the clinician possibility to adjust consistency of the mixture, however the working and setting time in self cure mode, and depth of cure in light cure mode, remain virtually the same. After the material is cured, in either self-or light-cure mode, it can be shaped in conventional manner using the same tools as for contouring composite restorative materials. FUNDAMENTAL RULESSaturn-M may be used in conjunction with, or without pins and posts. On vital teeth it is recommended to apply conservativ cavity preparation; in rounded retentive areas, it is also recommended to use Calcium Hydroxide base liner especially in situations involving proximity of the pulp, and over soft and decay-prone dentin, in order to provide an additional measure of protection against secondary decay. Conventional canal preparation, including toiletry with 15% Sodium Hypochloride solution and thorough drying of the preparation, is critical for providing maximum retentive strength. An alternative method of cavity preparation may include the use of Polycarboxylic acid solution with, or in place of, the Sodium Hypochloride solution. In order to achieve micro mechanical retention for maximum bond strength it is recommended to etch any enamel present. Saturn-M is Bis-GMA composite material an ingredient that in some people can cause an allergic reaction or result in skin or tissue irritation. Avoid contact with the core build-up paste. If contact occurs, wash immediately with soap and warm water. Improper use may result in allergic reaction of skin, or tissue irritation, in which case discontinue use of the product.
