Amalgam

Dental Amalgam — Encapsulated Alloy, Bulk Silver Powder, Squeezers & Polishing Kits

Dental amalgam is a silver-tin-copper alloy mixed with mercury to form a plastic mass that condenses, carves and self-hardens into a high-strength posterior Class I, II and V restoration. It remains the most cost-effective long-term posterior direct restorative material in load-bearing molar cavities where moisture control is poor, and is widely used in government, paediatric and trainee-volume practice. Dentalkart stocks encapsulated single-dose amalgam, bulk silver alloy powder, mercury squeezers and amalgam polishing kits from SDI Permite, DPI and Prevest DenPro.

Types of Dental Amalgam and Accessories

Encapsulated single-dose amalgam (mercury-sealed)

Pre-measured single-use capsules containing the alloy and mercury in sealed compartments — activated and trituated in a capsule mixer for consistent ratio, minimal mercury exposure and zero hand-mixing. The current standard-of-care delivery format for amalgam. For example, SDI Permite Capsules Spill-2 Regular Set.

Bulk silver alloy powder (powder + liquid mercury)

Pre-weighed silver-tin-copper alloy powder mixed with liquid mercury at the chair using a mortar and pestle or amalgamator — economical for high-volume restorative practice and trainee teaching settings. For example, DPI Dental Silver Amalgam Powder 15g.

Non-gamma-2 silver alloy

High-copper non-gamma-2 silver alloys eliminate the corrosion-prone gamma-2 (Sn-Hg) phase for higher tarnish resistance and marginal integrity. For example, Prevest DenPro Crysta Silver.

Mercury squeezers (excess-mercury control)

Cloth or rubber squeezer cones for safely wringing excess mercury from freshly trituated amalgam before condensation — reduces mercury content of the final restoration and improves long-term performance. For example, Samit Amalgam Squeezer Pack of 5.

Amalgam polishing kits

Multi-grit polishing burs, points and cups for finishing and polishing the set amalgam restoration at the recall visit — improves surface smoothness, reduces corrosion and extends restoration life. For example, Amalgam Polishing Kit.

When Dental Amalgam Is Used

• Posterior Class I and Class II restorations in molars under heavy occlusal load
• Class V cervical restorations on root surface where moisture control is difficult
• Cusp build-up under stainless-steel crowns or onlays
• Core build-up under cast crowns where bonded composite core is contraindicated
• Retrograde root-end filling (where indicated and bioceramic not available)
• Paediatric pulpotomy restoration on primary molars
• Quadrant dentistry on high-volume non-aesthetic posterior cases
• Cost-sensitive public-health and trainee teaching practice

How to Choose and Use Dental Amalgam Correctly

1. Prefer encapsulated single-dose amalgam (SDI Permite) over bulk powder-plus-mercury for safer mercury handling and reproducible alloy-to-mercury ratio.
2. For high-occlusal-load molar cavities pick a high-copper non-gamma-2 alloy (Permite, Crysta Silver) — better marginal integrity, lower long-term corrosion.
3. Mix capsules in a quality amalgamator for the manufacturer-specified trituation time — under-trituated mix is grainy and under-set, over-trituated mix has reduced working time.
4. Use a mercury squeezer on bulk-mix amalgam before condensation to remove free mercury.
5. Polish the restoration at the 24-hour recall visit using a graded amalgam polishing kit to improve surface smoothness and corrosion resistance.
6. Always store waste amalgam (including capsule shells) in a sealed labelled container under water or X-ray fixer for amalgam-recycler collection — never discard in general clinical waste or sink trap.

What is dental amalgam used for?

Dental amalgam is used for posterior Class I, II and V restorations in molars and premolars, Class V cervical restorations where moisture control is difficult, cusp build-up under stainless-steel crowns, core build-up under cast crowns, retrograde root-end filling, and paediatric pulpotomy restoration on primary molars — primarily in load-bearing non-aesthetic cases.

What is the difference between encapsulated and bulk amalgam?

The difference is delivery format and mercury safety. Encapsulated amalgam (SDI Permite) comes in pre-measured single-use capsules with the alloy and mercury sealed in separate compartments — activated and trituated in an amalgamator for consistent ratio and minimal mercury exposure. Bulk amalgam (DPI Silver Amalgam Powder) is hand-mixed with liquid mercury at the chair — economical but requires careful mercury handling.

What is a non-gamma-2 amalgam?

A non-gamma-2 amalgam is a high-copper silver alloy formulated to eliminate the corrosion-prone gamma-2 (tin-mercury) phase from the set restoration. The high copper content ties up free tin as a copper-tin phase instead. Non-gamma-2 alloys (SDI Permite, Prevest Crysta Silver) have better marginal integrity, higher tarnish resistance and longer clinical service life than older low-copper amalgams.

How do I safely dispose of dental amalgam waste?

Store waste amalgam — including used capsules, excess condensed amalgam and extracted teeth with amalgam restorations — in a sealed labelled container under water or X-ray fixer. Hand this to a licensed amalgam recycler. Never discard amalgam waste in general clinical waste, the sink trap or sharps containers. Fit a chairside amalgam separator on suction lines to capture particles.

Is the dental amalgam on Dentalkart genuine and CDSCO-compliant?

Yes, the dental amalgam on Dentalkart is genuine and CDSCO-compliant. SDI Permite capsules, DPI Silver Amalgam Powder and Prevest DenPro Crysta Silver ship in sealed primary packaging from authorised Indian distributors, with original batch number and expiry printed on every bottle and capsule pack.
