Why we have to use silicone rubber modulus?

Before making the restorations, are required to make the impression of the teeth, and then copy theoutside tooth form, this is one of the most important steps in making dentures. At this time, the precision of restoration through the impression material reflected.

This impression is of course more precise as possible, because directly affect the final quality of the restoration. Unfortunately, because of the cost and historical reasons, the use of silicone rubber infixed dentures, crowns of less. Restoration of precision degree can be imagined.

Strongly recommended: zirconia restorations and other high-end insist on the use of silicone rubbermolding, to ensure the quality of restoration, improve the satisfaction of patients.

The following for your gradual introduction of silicone rubber.

A common impression material, classification

(1) alginate: the advantage is cheap, simple operation; drawback is obviously, shrinkage is relatively large, can not reflect accurately the tooth morphology.

(2) agar: the advantage is cheap, the disadvantage is easily broken brittleness.

(3): the silicone rubber silicone rubber silicone rubber, such as Shanghai pigeon (pictured), is the most common brands available in the market. The utility model has the advantages of high accuracy, very stable, can be used for making various restorations.

Two, silicone impression materials overview

Silicone rubber is a kind of high molecular synthetic rubber, is irreversible elastic impression material. In recent years, widely used in the field of medicine, is one of the most ideal impression material at. The utility model has the advantages of mainly in the following three aspects:

(1) after solidification size is more stable, within 24 hours of the change in size stable at around 0.1%;

(2) a short operation time, rapid solidification in the oral cavity, first impression 3 minutes ofsolidification, impression two times to 3 and a half minutes;

(3) the impression of high accuracy, good operation performance; in addition, the silicone rubberimpression material is used in the same 1:1 composition viscosity of rubber mixture, and brings convenience to the clinical work.

Three, silicon rubber two step modulo operation (video)

Four, a detailed operation of silicone rubber (above)

1, for patients to choose suitable tray, the tray were asked to leave the teeth 3-4mm;

2, clean and dry hands, the operation process can not wear latex gloves;

3, the first impression

1) substrate and catalyst, take a spoonful of the maxillary proposal, take a scoop of mandibularproposal, ensure the base and catalyst 1:1;

2) using fingertips until the mixture is uniform in colour without stripes, will die proof well mixedknead strip into the tray, then put in the mouth, 3 minutes;

Note: with poly silicon rubber solidification time is affected by temperature, high temperature, fast solidification.

4, finishing a preliminary impression

Remove the first impression undercut shoulder, gingival papilla, tooth clearance using specialrepair type knife, repair overflow, convenient impression two times in place, to reduce air bubbles.

5, take impression two times

Just hit the light, may be due to uneven mixing and solidification effect, suggested that 1-2cmmaterial in front of you; will note light body material tray into the mouth, slowly and once in place,about 3 minutes and 30 seconds after curing material is removed from the mouth;

6, complete the examination and impression

1) for the preparation of subgingival impression, teeth at the edge of clear and complete, no bubble,shoulder clear and continuous;

2) since the mouth impression was taken out, placed 30 minutes (keep up can still be used within 30 days), no need to worry filling, can be directly sent to the immersion disinfection processing factory.
