Structures2 SC/KM

(Structur 2 SC/QM)

Instructions for use

Structures 2CC/K.M. is a cold polymerization paste-paste system for the manufacture of temporary crowns, bridges, inlays and onlays. Structures 2CC/KM consists of base and catalyst pastes. Structures 2CC Available in an assortment of 8 colors: A1, A2, A3, A3.5, B1, B3, C2 and BL. Structures 2KM Available in A1, A2, A3 and B1 colours.

Application:

Structures 2CC in cartouches:

Place cartouches with Structures 2CC into a mixing gun VOCO (type 2) or other suitable one. Before the first use, technically determined slight differences may be noted in the filling of both chambers of the cartouches. Remove the cap and squeeze out the material for so long until the same amount of material comes out of both holes.

Put on the mixing cannula type 6 and fix it by turning it 90°, pressing the lever to squeeze out the material, which is mixed in the correct proportion. After use, leave the cannula on the cartouche. Before next use, replace with a new cannula. When changing the cannula, check the openings of the cartouches for free flow of material.

Structures 2K.M.in QuickMix syringes:

Remove the protective cap from the syringe by turning it counterclockwise. Place the mixing cannula type 10. The grooves of the syringe and the mixing cannula must match. Secure the cannula by turning it 90° clockwise. During withdrawal, the material is automatically mixed in the cannula in the correct proportion and can be directly applied.
All Quick Mix syringes are equipped with a retractable piston. The plunger is easily removed from the syringe and reinserted.

The gaskets in the syringe do not change their position. This avoids mixing of materials in the syringe.

Processing instructions:

Smooth out existing unevenness of the prepared stump, but do not use eugenol-containing cements. If pre-fabricated dental caps or the like will not be used, take an impression.

Prepare the impression by smoothing out any irregularities and cutting out grooves for drains. With the expected small thickness of the walls of the temporary restoration, the impression is expanded, in particular removing partitions in the interdental spaces. Finally, clean the print and air dry it.

Structures 2CC/K.M. Apply directly onto the impression. Do not overfill.

Structures 2CC/K.M. approximately 1 - 1.5 minutes after the start of mixing (0.5 - 1 minute after application to the oral cavity) it reaches an elastic consistency.

The temporary restoration can be removed from the mouth after 1.5 minutes, but removal without problems is only possible in the elastic phase.

Excess material provides additional control over the bonding process in the mouth. The binding time of the material remaining in the cannula is not comparable to the binding time in the oral cavity.

At a room temperature of 23°C and air humidity of 50%, the duration of the processing stages is as follows:

Duration	Timing
Application to the oral cavity	30 sec
Binding in the mouth	1 min
Removal	1.5 min
Full Binding (2.5 min)	4 min
Further processing

Due to different room temperatures, deviations may occur.

After approximately 2 - 3 minutes, remove the temporary restoration from the impression and dry (it is possible to use, for example, ethyl alcohol). This eliminates the usually formed thin layer inhibited by oxygen and facilitates further processing. The surface of the temporary restoration should have a matte, silky appearance.

Finally, carefully sand off excess and rough areas in the gum area. Secure the completed temporary restoration with eugenol-free temporary cement.

Directions and precautions:

- Structures 2CC/K.M. contains BIS-GMA, amines, terpenes, benzoyl peroxide, BHT, do not use if you are allergic to individual components

To protect against increased sensitivity, the prepared stumps can be isolated (fluoride varnish, e.g. stump varnish, etc.) before fixing the temporary restoration.

To avoid fractures and damage, the temporary restoration should not experience heavy load (molar area)

Fillings and stumps made from composite-based materials must be carefully isolated to prevent their removal along with temporary restoration (eg glycerin)

Poor hygiene or heavy use of mouth rinses can cause discoloration

Begin processing the temporary restoration after it has completely hardened (approximately 4 minutes after the start of mixing)

Repairing temporary restoration:

If, despite the high strength Structures 2CC/K.M. If a structural fracture occurs, it is recommended to follow the following instructions:

- Air dry the temporary restoration:
Just fill it out Structures 2CC/K.M. .

- In case of fracture immediately after production:
Glue the fracture sites using freshly prepared Structures 2CC/K.M..

- Repairing restorations used by the patient:

Grind the surfaces to be bonded using a milling cutter. Apply adhesive liquid to the fracture sites and polymerize according to the instructions. Apply flow material to the prepared surfaces, connect the fracture sites and polymerize in accordance with the instructions for use.

Storage instructions:

Store at a temperature of 4 °C – 23 °C.

Store cartouches in a place protected from light, in closed packaging, in a drawer, etc.

Addressable memories are presented in the classification by static and dynamic operational devices and ROM type memory. Numerous variants of these memory devices have much in common from the point of view of structural diagrams, which makes it more rational not to specifically consider each memory device in full, but to study some generalized structures with a subsequent description of storage elements for various memory devices.

The similarity of structures is especially evident for static RAM and ROM type memory. Dynamic RAM structures have their own specifics. The most typical structures for static RAM and ROM memory are 2D, 3D and 2DM.

2D structure

In a 2D structure, the GE storage elements are organized into a rectangular matrix with the dimension

where M is the information capacity of memory in bits;

k - number of stored words;

m is their bit depth.

The 2D type structure is used only in memory with small information capacity, since as the capacity increases, several of its disadvantages appear, the most obvious of which is the excessive complexity of the address decoder (the number of decoder outputs is equal to the number of stored words).

3D structure

The 3D structure makes it possible to dramatically simplify address decoders using two-dimensional sampling of storage elements. The principle of two-coordinate sampling is illustrated in Figure 17 using the example of a ROM type memory that implements only data read operations. Here, the n-bit address code is divided into two halves, each of which is decoded separately. The memory element located at the intersection of the active output lines of both decoders is knocked out. There will be just such intersections

with a single-digit organization.

Figure 17 - Structure of a 3D type memory

The total number of outputs of both decoders is

which is much less than 2 n for real values of n. Even for a small-capacity memory, this significant difference is visible: for a 2D structure, storing 1K words would require a decoder with 1024 outputs, while for a 3D structure, two decoders with 32 outputs each are needed. The disadvantage of the 3D structure is primarily the complication of memory elements that have a two-dimensional sample. Structures of the 3D type also have a rather limited application, since structures of the 2DM (2D modified) type combine the advantages of both considered structures - address decoding is simplified, and storage elements with two-coordinate sampling are not required.

2DM structure

The ROM type memory of the 2DM structure shown in Figure 18 for a matrix of storage elements with addressing from the DCx decoder has the character of a 2D structure: the excited output of the decoder selects the entire row. However, unlike the 2D structure, the length of the string is not equal to the bit depth of the stored words, but many times exceeds it. In this case, the number of matrix rows decreases and, accordingly, the number of decoder outputs decreases. To select one of the lines, not all the bits of the address code are used, but their part A n -1 ... A k. The remaining bits of the address (from A k -1 to A 0) are used to select the required word from the set of words contained in the line. This is done using multiplexers, the address inputs of which are supplied with codes A k –1 ... A q.

The length of the string is equal to m2 k, where m is the bit depth of the stored words.

From each “segment” of a string 2 k long, the multiplexer selects one bit. An output word is formed at the outputs of multiplexers. Based on the resolution of the CS signal arriving at the inputs of the OE controlled buffers with three states, the output word is transmitted to the external bus.

Figure 18 – Structure of 2DM type memory for ROM

Data in the desired segment of this line is written (or read from it) by controlled data buffers BD, which perceive the output signals of the second decoder DC Y, and perform not only multiplexing functions, but also functions of changing the direction of data transmission under the influence of the R/W signal.

Conclusion:

Storage devices (storage) are used to store information and exchange it with other digital devices, and the following levels can be distinguished:

Cache is a memory used to store copies of information used in current exchange operations;

Main memory (RAM, permanent, semi-permanent), operating in direct exchange mode with the processor and, if possible, coordinated with it in terms of speed;

Specialized types of memory, characteristic of some specific architectures (multiport, associative, video memory, etc.);

External memory that stores large amounts of information.

The main parameters include: information capacity, storage organization, speed (performance), minimum acceptable interval between successive reads or writes.

Addressable memories are divided into RAM (Random Access Memory) and ROM (Read – Only. Russian synonyms for the term RAM: RAM (operational memory) or ZUPV (random access memory). In ROM (Russian equivalent - ROM, i.e. permanent memory ) the contents either do not change at all, or change, but rarely and in a special mode.RAM is divided into static and dynamic.

According to the structure, memories are divided into 2D (with low information capacity), 3D (decoding is simplified), 2DM (the advantages of both considered structures are combined - address decoding is simplified, and storage elements with two-dimensional sampling are not required).

Control questions:

1 By what criteria are semiconductor storage devices classified?

2 How is the information capacity of a memory determined?

3 List the main parameters of the memory?

4 Explain the principle of operation of the 2D structure memory.

5 How can you organize a memory with an information capacity of 1K?

The transition to this type of organizational structure was determined by:

· increased diversification of business activities;

· management specialization;

· international division of labor;

· increased awareness, self-esteem and expectations of middle managers.

The divisional structure differs from the linear-functional structure by greater flexibility, which ensures speed of decision-making and is its advantage in conditions of rapidly changing market conditions and technological innovations.

The main advantages of the divisional structure:

· Flexibility (most effective in a dynamic environment);

· Efficiency of decision making;

· Interdisciplinary approach;

· Quickly resolve complex cross-functional problems;

· Focus on new technologies and markets;

· Focus on non-price competition.

Disadvantages of the structure include conflicting interests of individual divisions and the enterprise as a whole, duplication of management functions (growth of the management apparatus and low efficiency). As the enterprise grows, this can lead to loss of control.

Matrix organizational structure

Matrix organizational structure arises in conditions of diversified production, when an enterprise develops and produces diverse types of products, implements several investment projects, etc. such a structure is a synthesis of linear-functional and divisional structures.

General instructions are given to performers by line managers, and specific instructions are given by individual project managers. The latter are vested with special powers, make decisions, combine and interpret information coming from functional units, and monitor the progress of projects. The orders of line managers are agreed in writing with the managers of individual projects in cases where they relate to work on this specific project.

The main advantages of the matrix structure are flexibility, dynamism, guarantees of maintaining and expanding technological capital and innovative activity. The personal interest of the project manager in his success, due to the desire for professional growth and the identification of individual and collective goals, stimulates team cohesion and ensures an increase in labor productivity. Therefore, this structure is often used when executing projects that are limited in time.

One of the disadvantages of the matrix structure is that its implementation is not accompanied by compliance with the principle of one-dimensionality in management, as a result of which each subordinate has not one, but several managers, whose orders can often be contradictory.

Conclusion.

An analysis of the essence, advantages and weaknesses of a particular organizational structure provides serious grounds for justifying the choice of its specific type for an actually operating or newly created enterprise. However, this factor cannot be limited to when making adequate management decisions. The following must also be considered:

1. First of all, the choice of organizational structure is influenced by the size of the enterprise - the amount of capital, fixed assets, and the number of employed personnel.

2. A very strict determining condition for the organizational structure of an enterprise is the technology it uses.

3. The territorial size of the market served by one company also determines the features of its organizational structure.

4. The most important factor in the structural dynamics of an enterprise is the nature of the external environment - the degree of its uncertainty, predictability and speed of change.

5. Finally, one of the reasons for choosing the type of structural structure of an organization is the personal characteristics and experience of managers, including, and above all, top management.

Structur 2 SC/QM (Structure 2 SC/KM)
Approved for use in the territory No. Federal Law No. 2011/09580
Instructions for use
Description of material:
Structure 2 SC/KM is a fluorescent self-curing paste-paste system for the manufacture of temporary crowns, bridges, inlays and onlays.
The material of Structures 2 SC/KM consists of base and catalytic pastes. Structure 2 SC is available in eight shades: A 1, A 2, AZ, AZ,5, B 1, VZ, C 2 and BL.
Structure 2 KM is available in shades: A 1, A 2, AZ and B 1.

Application:
Application of Structures 2 SC in cartridges:
Install the cartridge with Structure 2 SC in a VOCO dispenser type 2 or a dispenser of a similar type. Before first use, there may be a slight difference in the filling level of both parts of the cartridge.
In this regard, remove the cartridge plug and squeeze out the material until its exit from both holes is uniform. After this, install the mixing cannula (type 6) on the cartridge and fix it by turning it 90°. The material is extruded by a lever and automatically mixed in the correct ratio. The specified properties of the product are achieved only when using original Mix-Pack mixing cannulas manufactured by Sulzer, tested by the VOCO Company. All suitable cannulas for use with our products can be purchased from VOCO.
After use, leave the mixing cannula on the cartridge. Immediately before the next use of the material, replace the cannula with a new one. When replacing the cannula, check the cartridge outlets for free flow of material.
Application of Structures 2 KM in QuickMix dispensers:
Before first use, a slight difference in the filling level of both parts of the dispenser is technically permissible. Remove the protective cap of the dispenser and squeeze out the material until it comes out evenly from the two holes. Insert the mixing cannula (type 10). The holes in the dispenser and mixing cannula must match. Secure the cannula by turning 90° clockwise. When extruded, the material is automatically mixed in the cannula in the correct ratio and is immediately ready for use.
All KM dispensers have retractable rods. The rod can be removed from the dispenser and reinserted.
At the same time, the gaskets located in the dispenser remain in place. This prevents contamination of the material in the dispenser.

Processing instructions:
Eliminate undercuts after preparation; do not use eugenol-containing cements.
If the use of ready-made dental caps is not provided, then make an impression.
Prepare the impression by smoothing out the undercuts and cutting out the outlet channels. If the thickness of the walls of the temporary structure is expected to be small, the impression should be expanded and, above all, the partitions in the proximal spaces should be removed. Then clean the cast and dry it with a stream of air.
Apply Structure 2 SC/KM directly into the impression. Apply without excess.
Structure 2 SC/CM reaches an elastic consistency in ≈1–1.5 minutes. after the start of mixing (≈0.5–1 minutes after insertion into the oral cavity), remove the temporary structure from the oral cavity at the latest after 1.5
minutes after the start of mixing, since its trouble-free extraction is only possible during the elastic phase.
The curing process must be further monitored on excess material in the oral cavity. The curing time of unused residual material in the mixing cannula does not correspond to the curing time in the mouth.
At a room temperature of 23 °C and air humidity of 50%, the operating time will be as follows:
0:00–0:30 - insertion into the oral cavity
0:30–1:00 - grasping in the oral cavity
1:00–1:30 - removal from the mouth
1:30–4:00 - full setting
4:00 processing
Deviations may occur due to differences in room temperatures.
After 2–3 minutes, remove the temporary structure from the impression and dry it (using a solvent, for example, ethyl alcohol). This eliminates the usual thin layer inhibited by oxygen and makes further processing easier. The surface of the temporary structure should be matte-silky. Then carefully sand off any excess and roughness in the gum area.
Fix the finished structure with eugenol-free temporary cement.

Instructions, precautions:
- Structure 2 SC/CM contains methacrylate, amines, terpenes, benzoyl peroxide, BNT. If you have hypersensitivity (allergy) to these components of Structures 2 SC/KM, you should avoid using it.
- To avoid increased sensitivity, the treated stumps can be further isolated before making a temporary structure (fluoride varnishes, stampflakes, etc.).
- To avoid fractures or damage from splinters, temporary structures should not be subjected to excessive load (molar area).
- Carefully insulate (eg glycerin) the composite spacers and core inlays so as not to remove them along with the temporary structure.
- Poor hygiene or intensive use of certain mouth rinses can cause discoloration of the temporary material.
- Process the temporary structure only after the material has completely cured (approximately 4 minutes after the start of mixing).
- Repair of temporary structures:
If, despite the high strength of the material of Structures 2 SC/KM, damage to the temporary structure occurs, it is recommended to do the following:
- air pores: simply fill with the material of Structures STs/KM Structures 2 STs/KM, freshly mixed material of Structures 2 STs/KM.
- damage immediately after production: fasten the fracture points with freshly mixed material Structure 2 STs/KM.
- repair of structures that are in use: using a milling cutter, roughen surfaces at fracture sites and create retention points. Apply the bond to the prepared fracture sites and polymerize in accordance with the instructions for use. Apply the fluid material to the prepared surfaces, connect the fracture points and polymerize in accordance with the instructions for use.

Storage recommendations:
Store at 4 °C - 23 °C. After the expiration date, the material should no longer be used.
Store cartridges in a place protected from light, i.e. in closed packages, desk drawers, etc.
