Abstract:
Temporary crowns are of critical
importance in orthopedic treatment. The term
"temporary restorations" refers to those that have
been installed for some time and require
subsequent mandatory replacement of the
restoration. Even if the final restoration is
installed soon after dissection. Unfortunately, the
word "temporary" implies some negligence,
which often means ignoring many of the
requirements related to permanent restorations.
If such a connotation becomes the philosophy of
the intermediate stage of treatment, it will
necessarily lead to a decrease in clinical
effectiveness and overall quality of treatment.
INTRODUCTION
Strict observance of all the rules and conditions for the manufacture of temporary restorations is never
a waste of time.

• Removing the silicone key is one of the most important steps, as the quality and accuracy of
manufacturing a temporary structure depends on it.
• It is necessary that the impression includes adjacent teeth from the prepared ones, for its further
correct positioning in the oral cavity.
• When preparing all teeth of the upper jaw, it is necessary to capture pa
rt of the hard palate when
making a silicone key, this additional area will facilitate the positioning of the impression in the oral
cavity.
• When preparing all the teeth of the lower jaw, it is necessary to capture the alveolar process from the
oral side, this additional support will facilitate the positioning of the impression in the oral cavity.
• In cases of preparation of all teeth on the upper or lower jaw, it is recommended to use a standard
impression spoon of the appropriate size, this will avoid many difficulties and inaccuracies.
Possible errors at this stage
Taking an impression only from the teeth being prepared.
The reason: the lack of a clear plan for the manipulations carried out can lead to the production of an
impression without including adjacent teeth, and other areas that allow the silicone key to be correctly
positioned in the oral cavity, temporary structures made according to such an impression will be
incorrect in occlusal ratios and will require significant refinement.
Solution: re-manufacturing of a silicone key with the inclusion of adjacent teeth and areas in the
impression that allow the impression to be positioned correctly.
The braces are in a silicone key.
Reason: at the time of the polymerization stage of the silicone mass, an attempt was made to untimely
change the shape of the silicone key, this may occur due to non-compliance with the working time with
the material or an incorrect mixing ratio of the silicone mass.

89
Solution: re-manufacturing of the silicone impression, otherwise the accuracy of the manufactured
temporary structures will be mediocre, it will take more time to process such structures than to re-
manufacture the impression.
The presence of "unrecognized" areas of the teeth being prepared.
The reason: the manufacture of a silicone key without using a standard impression spoon, especially in
areas with difficult access (for example, the lower molars) leads to the presence of "unrecognized"
areas, this is often observed in the area of the lower molars.
Solution: re-manufacturing of the silicone key using a standard impression spoon, its use will facilitate
obtaining a satisfactory impression, otherwise temporary structures made using an invalid impression
will require long-term refinement.
Preparation of the silicone key
The manufactured silicone key must be prepared as follows:
From the vestibular side, using a scalpel (or a silicone knife), the impression is cut off along the zenith
of the teeth to allow the outflow of excess material.
On the oral side, shallow furrows are created coming from the base of the gingival papillae, thus creating
space for the outflow of excess material. To create such depressions, it is especially convenient to use a
knife for cutting channels in silicone, or a knife in the shape of a spoon.
Silicone knives can be used instead of a scalpel.
Possible errors at this stage
The absence of oral depressions.
The reason: this error is often made from haste and inattention, the absence of these depressions will
lead to the spread of excess material over the palate or sublingual area, this can make it difficult to
extract the structure from the oral cavity and cause unpleasant sensations in the patient.
Solution: monitoring compliance with the stages of manipulation.
Inaccuracy in the processing of the vestibular area of the silicone key.
Reason: imperfection in the use of a silicone knife or scalpel can lead to excessive removal of silicone
mass in the cervical region of the teeth being prepared, or vice versa, insufficient removal of silicone

90
mass. Temporary structures in such cases will have overhanging edges, inaccurate posterior fit, and it
will take a little more time to process such structures.
Solution: practicing manual skills in preparing silicone prints.
Preparation of teeth
The preparation consists in hemostasis and covering the teeth with a thin layer of vaseline so that the
manufactured structure can be easily removed from the prepared teeth.
In cases where there are new composite restorations on the teeth being prepared, or the stump of the
tooth has been restored with composite material, it is necessary to abundantly cover such areas with
vaseline. Otherwise, an adhesive bond will occur between the material for the manufacture of
temporary structures and the composite restoration and it will be impossible to remove the temporary
structure without compromising the restorations.
Before inserting the silicone key with the material into the oral cavity, it is recommended to try on the
impression without the material in order to determine the route of administration and its correct
position.
Possible errors at this stage
The absence of a separating layer
The reason: neglecting the stage of coating teeth with a layer of vaseline or other separating material
will lead to difficult, and in the presence of new composite restorations, it will be impossible to extract
temporary structures for further processing.
Solution: monitoring compliance with the stages of manipulation.
Insufficient hemostasis in the area of prepared teeth.
Reason: neglecting careful hemostasis of the gum will lead to blood entering the material, the presence
of blood inclusions in the temporary structure will lead to the formation of pores, in some cases it is not
possible to completely remove or wash away blood inclusions from the material, which will lead to
darkening of the inclusions and unsatisfactory aesthetics of the temporary structure.
Solution: paying attention and time to thorough hemostasis.
Stage 4. Adding material to the silicone key
Before applying the material, it is advisable to squeeze out the first small portion of the composite from
the cannula, since this first portion does not mix well enough and may remain viscous, which will lead
to voids.
The material is introduced into the silicone key slowly, starting from the occlusal surface continuously,
in one portion, this method of introducing the composite will avoid the appearance of pores. Next, a
portion of the material is applied to the ledge of the prepared teeth, this allows for a good edge fit of the
temporary structure, this stage is especially important during deep subgingival preparation.
Possible errors at this stage
Pores when applying the material to the silicone impression
Reason: if the material is introduced into the impression in several inhomogeneous portions, or the
material is introduced from the posterior region of the impression, and not from the occlusive one, voids
are likely to form in the manufactured structure. Such a temporary structure cannot be polished to a
perfectly smooth surface, in most cases it has an unsatisfactory edge fit and aesthetic disadvantages.
Solution: application of the material in one homogeneous portion starting from the occlusal surface of
the impression.
Stage 5. Inserting a silicone key into the oral cavity
A silicone key with the material is inserted into the oral cavity and positioned.

91
After 90 seconds, the silicone key is removed along with the structure (the time may vary depending on
the manufacturer and the material used), in most cases the structure remains in the impression, if the
structure remains on the teeth, it must be carefully removed from the oral cavity for further processing.
Possible errors at this stage
Insufficient or excessive polymerization of the material.
Reason: Failure to observe the operating time and deviation from the manufacturer's instructions can
lead to significant difficulties. If the silicone wrench is in the oral cavity for less than the recommended
time for initial polymerization, then the material will remain viscous when removed. If the silicone key
is removed later than the recommended time, the material will shrink and it will be very difficult to
remove the structure from the prepared tooth.
Solution: re-manufacture of a temporary structure with strict observance of the working time of the
material used.
Stage 6. Polishing and processing of crowns
During the polymerization of composite materials, a sticky oxygen-inhibited layer forms on their
surface. You can remove this layer using ethyl alcohol.
After removing the inhibited layer, using a straight tip and a cutter, all sharp edges are eliminated, the
posterior area of the crown is necessarily thinned to prevent gum pressure, the crown is contoured and
polished to a smooth surface.
If the structure is made for a long time or will be located in an aesthetically significant area, it can be
varnished for temporary structures, this will give it a glossy sheen and prevent it from staining with
coloring products.Possible errors at this stage
The presence of sharp edges, unsatisfactory polishing.
The reason: careless processing of the structure will lead to the presence of sharp edges and roughness,
which will cause discomfort to the patient, and will necessarily lead to immediate re-admission.
Solution: careful processing and polishing of the temporary structure.
The presence of a thick posterior edge.

92
The reason: the absence of thinning of the posterior edge of the temporary structure leads to
compression of the gum, which leads to its inflammation and discomfort.
Solution: monitoring compliance with the stages of manipulation.
Stage 7. Fixation
The manufactured structure is fixed on Temp Bond temporary cement, excess cement is removed.
