•
The restorative cures to great depths with light induced curing
mechanism, without the necessity of mixing. •
When mixed with Part B Paste or Part B Liquid Accelerator, 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
Eagle 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 structure and 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 Eagle are notably superior to that of the properties of glass ionomer type cements. Dent Zar,

COMPARISON OF PROPERTIES OF CURED EAGLE WITH GLASS
IONOMER CEMENTS AND
WITH THE REQUIREMENTS OF ADA SPECIFICATION NO.27 FOR
COMPOSITE RESTORATIVES
APPLICATION TECHNIQUES
Eagle 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 ONLY
When the thickness of the
restoration is less than 4mm, or when the restorative is applied in more than
one layer the Part A Restorative Paste Natural, or Contrast Shade may be used
alone, ie., without mixing with the Part B Liquid,
or Part B Paste-catalyst 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. NOTE: Contrast will change the color from blue to pink
during the curing process. The color change insures deep light penetration
and thorough curing of the material. (Once the material is completely
polymerized, it will return to its original color in 3 to 7 days). This
enables it to be easily distinguishable from the tooth structure. After
placement, cure light cure Eagle Core Build-Up material for 20-90 seconds
from facial, lingual and occlusal aspects. DUAL-CURE MODE
For curing in thick layers, for cementing posts, or in situations where thinner consistency of the restorative is desired, Part A Restorative Paste Natural or Contrast Shade should be mixed with Part B Paste, or Part B Liquid. The mixing with Part B Paste or Part B Liquid 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 RULES
• Eagle may be used in conjunction with, or without pins and posts. On vital
teeth it is recommended conservative cavity
preparation; with rounded retentive areas,
it is also recommended to use Calcium Hydroxide base liner especially in situation 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 ma 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. • Eagle 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. CUSTOM EAGLE KITS AVAILABLE: Eagle all contrast, all natural, or any
combinations desired.
STORAGE: Do not store or expose kit to temperatures over 72ºF
(22ºC).
