Ultrasonic dental cleaning - safe and thorough instrument reprocessing

BANDELIN ultrasonic cleaner are used in dental practices to pre-clean instruments - the crucial first step in the reprocessing process. The devices completely remove blood, saliva, cement and polishing pastes without damaging surfaces. The process is contact-free, reproducible and complies with the recommendations of the KRINKO/RKI. Each system is manufactured in Berlin, is ISO 9001- and ISO 13485-certified and thus fulfils the regulatory requirements for validatable cleaning in medical facilities.

Why ultrasonic cleaning is indispensable in the dental practice

Instruments that come into contact with blood, saliva or cement residues must be completely cleaned before disinfection. In the Dental practice This applies to surgical tools as well as mirrors, pliers and drills. Manual cleaning is error-prone, time-consuming and harbours the risk of injury. The Ultrasonic bath replaces these steps with a controlled, physical process that delivers consistent results regardless of staff experience.

The Cavitation generates millions of microscopic bubbles that release energy when they collapse and loosen even stubborn deposits in the smallest recesses. This achieves a reproducible cleaning result even with complex shapes, fine cutting edges or delicate files. The risk of cuts or punctures is reduced because no direct contact with contaminated instruments is required. At the same time, the process saves time: several trays can be treated at the same time, significantly reducing throughput times.

How the cavitation principle works with dental instruments

In the Ultrasonic field alternating phases of negative and positive pressure occur due to rapid pressure changes. Tiny bubbles form in the liquid. Cavitation bubbles, which implode in a fraction of a second. This effect creates fine microcurrents that remove dirt particles and deposits from surfaces - even in drills, files, brackets or instruments with threads and joints.

The effect is uniform, gentle on the material and also reaches areas that remain inaccessible during mechanical cleaning. The frequency of 40 kHz ensures an optimum balance between cleaning intensity and surface protection.
For particularly sensitive instruments, the power can be reduced to ensure gentle treatment.

In combination with the matching Cleaning chemistry the effect is significantly enhanced. Surfactants, enzymes or complexing agents dissolve organic and inorganic residues, while cavitation removes them completely. The temperature of the bath is regulated between 40 and 60 °C, depending on the preparation, in order to optimise the chemical-physical effect.

Important requirements for ultrasonic cleaners in the dental sector

BANDELIN systems are as Class I medical devices authorised according to MDR and bear the CE and MD labelling. All devices are manufactured under a certified quality management system - documented in accordance with ISO 9001 and ISO 13485. They therefore fulfil the high requirements for use in dental practices, clinics and dental laboratories.

For facilities subject to validation, the Smart series with digital control and process documentation. Time, temperature and programme selection are automatically recorded and can be exported. This means that all process steps can be documented in an audit-proof manner - a decisive advantage for audits and hygiene checks.

The standardised design of all appliances ensures that cleaning parameters remain precisely reproducible. Each stainless steel tank is chemical-resistant, seam-welded and tested for even sound distribution. This creates a validatable process that enables legally compliant verification and stable cleaning results over many years.

Technical criteria for selection - appliance, cleaning solution & equipment

Choosing the right Ultrasonic cleaner depends on the type of instrument, volume and workflow. For everyday practice, compact table-top devices such as SONOREX RK 102 H, DT 102 H or Smart 102 ideal. They offer a tank size of one to two litres and are therefore ideal for single instruments or smaller instrument sets.
For dental laboratories or larger practice units, the RK-514 series with a total volume of up to 13 litres are available - ideal for complete dental trays.

The technical components of all series are customised for dental use

Frequency range of 40 kHz for fine cleaning of sensitive materials

Precisely tuned Sound generator Made of special ceramic for stable performance

Drain taps and filter options for easy bathroom maintenance

Accessories such as baskets, holders and bucket racks for ergonomic working

The effectiveness of the cleaning process depends crucially on the Cleaning solution from. BANDELIN recommends harmonised preparations such as STAMMOPUR DR, STAMMOPUR Z or STAMMOPUR RD5, specially developed for dentistry and dental laboratories. They remove organic and inorganic soiling, protect sensitive surfaces and extend the service life of the bath.

Advantages for your practice workflow - time, safety, service life

The Ultrasound cleaning significantly shortens the throughput time in instrument reprocessing. While manual methods process individual instruments one after the other, entire trays can be cleaned simultaneously with ultrasound. The results are reproducible, independent of the user and without any risk of damage or contamination.

This creates a clear efficiency advantage in everyday practice

Shorter turnaround times, higher instrument availability
No direct contact with contaminated instruments → more occupational safety
No brushes or abrasive agents → Longer tool life
Uniform cleaning even with complex shapes and fine tips
Standardised processes that can be easily integrated into existing hygiene chains

For the team, this means less effort and higher process quality at the same time. Even with delicate materials such as NiTi or fine incisors, dimensional stability is maintained - a decisive factor in implantology and endodontics.

Application examples & best practice - instruments, soiling, process

Typical Cleaning goods in dentistry are surgical and diagnostic instruments, dental handpieces, prostheses, brackets, impression trays, files and forceps. All are made of materials that are suitable for Ultrasound cleaning usually stainless steel, titanium or special dental alloys.

Typical soiling:

Blood, saliva and tissue residues

Cement and gypsum residues

Polishing pastes and impression materials

Dried alginate and silicone residues

The recommended procedure:

Immediate pre-cleaning after treatment to prevent drying

Sound system in an ultrasonic bath with a suitable STAMMOPUR preparation

Rinse off with demineralised water

Drying and transfer to thermal disinfection or sterilisation

BANDELIN offers suitable accessory solutions for trays or large instrument sets: Baskets with a fine sieve structure, holders for impression trays or baskets with lids. This makes the cleaning process ergonomic, efficient and safe.

Future trends in dental ultrasonic cleaning - digitalisation, automation, sustainability

The requirements for the Dental hygiene are changing with the increasing digitalisation and automation of practice processes. BANDELIN develops systems with digital control, touch operation and interfaces for process documentation. The Smart series enables the automatic logging of cleaning parameters, which facilitates audits and verification.

New materials in dentistry - for example Zirconium, hybrid ceramics or NiTi alloys - require precise and gentle processes. BANDELIN responds with optimised frequency profiles, energy-efficient control and even more even sound distribution.
In manufacturing, the company focuses on sustainable production processes, durable components and repairability - for lower operating costs and a better environmental footprint.

As Full-service provider BANDELIN supplies everything from a single source: ultrasonic devices, customised cleaning preparations and accessories. This results in systems that cover the entire dental sector - from stand-alone devices to networked solutions for larger practices and laboratories.
