What Is an Dental Ultrasonic Cleaner for Dentist Office?

Posted on by dentalyoyo520

Ultrasonic cleaners use ultrasound (the same waves that produce ultrasound images) frequencies and a cleaning solvent to clean materials such as dental and lab equipment, jewelry and industrial products. In the 1950’s, the first professional dental ultrasonic cleaner was introduced to the market and commercial ultrasonic cleaner machines were used in homes two decades later.

Ultrasounic cleaners use cavitation, the bubbles created by the sound waves in the tank, to clean the surfaces of items. The bubbles act as a sponge to scrub away dirt, blood and other contaminants that are on these items so that they can be sterilized afterwards.

Choosing the Right Cleaning Solvent

The cleaning solvents used in an ultrasonic washing machine can be as simple as water or as complicated as chemicals depending on the application needs. These cleaners can remove a variety of contaminants including oil, bacteria, fingerprints, mold, blood and soil and are used in many industries. They are most commonly used by dentists to prep their dental instruments prior to sterilization.

When choosing the correct cleaning solvents, you need to consider the items being cleaned and the ultrasonic cleaner’s metal tank that holds the instruments in place.

Disinfectants shouldn’t be used in your used ultrasonic cleaner because these machines don’t sterilize or disinfect, so disinfectants can be too harsh. The pH and acidity of the solution needs to complement the instruments so that it does not cause discoloration or mineral deposits. Many dental offices use neutral and alkaline solutions because they don’t damage the machine nor the instruments it contains.

In recent years, there has been an increase in enzymes and rust preventors used in ultrasonic cleaning solutions. These enzymatic cleaners break down biological organic materials that would otherwise be difficult to remove.

Caring for Your Ultrasonic Cleaner

Be sure to remove your ultrasonic cleaning solutions when they become cloudy and filled with particles. Always remove and replace these solutions with gloved hands to avoid contamination and skin irritation.

Clean the tank routinely with a scouring agent like Comet, but do not use course cleaners or cleaning pads that will leave scratches in the stainless steel. These scratches can trap bacteria and other harmful materials in your machine lessening the cleaning power of your machine.

Ultrasonic cleaner are environmentally friendly, time and energy efficient and flexible for many applications. Duraline Systems has many different model ultrasonic cleaners and accessories from leading ultrasonic cleaning machine manufacturers like our Tuttnauer ultrasonic cleaner machines.

How to maintenance dental handpiece for longer time

Posted on by dentalyoyo520

Dental handpiece maintenance is critical for us, after all, dental handpiece is expensive and relatively friable, gently take and put is necessary. Because the resin frames between the dental handpiece and wind round ball is more afraid of wrestling, while it is also more expensive for repair, so take caution. It is best to avoid the bump in the transfer process, be sure to clip needle clip firmly, and before and after the two clamp spring force should be uniform, not in order to put the needle forward exploration lengthen this will hurt clip spring, in the need to use an extension bur reed relatively cheaper than the clip.

Dental handpiece should be promptly cleaned and injected oil, when used dentist should idle for 30 seconds, so avoid keeping the oil to get into the patient mouth, although oil is now harmless, but if the fill operation getting the resin surface, the effect will be poor. Periodically turn on maintenance and cleaning. When the dental treatment is completed you’d better remove the dental handpiece to avoid dental handpiece knocked down on the ground broke when patient left the chairs; rise the operating table after complete to drain the water in the pipe completely, in the evening operating table can be placed handrails on leveraging in order to reduce the burden on the arm to increase the service life, maintenance of dental equipment online is very important for us, after all these must be out from the profits, or it is better to carefully use for extended life.

Que puede ocasionar fallos en las turbinas dentales?

Rodamientos (específicamente la jaula del rodamiento) generalmente fallan entre los primeros, principalmente debido a:
fragmentos
excesiva presión del aire
temperaturas muy altas durante el proceso de esterilización
Desgaste causado por carga lateral
Agua del tanque de almacenamiento de aire del compresor de aire dental.
Uso de tornos doblados o de un torno mal encajado
Uso de cojinetes de bola de mala calidad de origen desconocido
Rápido enfriamiento de las piezas de mano con agua fría después de su autoclave esterilizacion. Rápido enfriamiento puede causar deformación de algunas partes de la pieza de mano, así como contaminar las herramientas ya esterilizadas.
Poner la pieza de mano odontologia en marcha sin el torno. Esto puede dañar los mecanismos del husillo o del mandril.
Lubricación irregular. El mandril debe lubricarse por lo menos una vez por semana para mantenerlo limpio y para propiciar su buen funcionamiento. Los fragmentos pueden obstruir el mandril y afectar a la fijación del torno.
Es muy importante usar los tornos adecuados. Uno de los errores más comunes en lo que se refiere a las turbinas dentales es el uso de tornos inadecuados que poseen un diámetro inferior a 1,59 mm. Lamentablemente en el mercado hay muchos tornos más finos o más blandos, que provienen de unos fabricantes low cost y que son atractivos gracias a su bajo precio. Pero si los tornos son demasiado finos o blandos, no se sujetan bien en el mandril. Girando alrededor de 300.000 revoluciones por minuto o más, tarde o temprano estos tornos empezarán a desviarse y acabarán causando daño al mandril.
Otro factor que afecta al funcionamiento del torno es mala Resistencia al desgaste de la boquilla (el hueco en el que el torno se inserte). La boquilla debe ser de carburo o acero endurecido y debe estar separada del mandril (ver dibujo abajo). Muchos fabricantes de rotores para las piezas de mano dentales juntan el mandril y la boquilla en una misma pieza porque esto simplifica el diseño del husillo y así se reduce el gasto de la fabricación. Pero esa técnica no es la mejor opción para aumentar la resistencia de la boquilla al desgaste. Las presión que sufre el torno en el transcurso de la operación puede desgastar la boquilla, dejando al torno más espacio para moverse radialmente. Debido a este movimiento radial los dentistas  ya no consiguen tener la misma precisión trabajando con su pieza de mano. El aumento de este movimiento también afecta a la vida útil del rodamiento.

Which Dental Tools Are Better for Cleaning Your Teeth?

Posted on by dentalyoyo520

Which is better for cleaning your teeth: dental ultrasonic scaler or dental hand tools? In the following you will get answer.

Dental plaque (a film of bacteria that forms on your teeth) is known to be the main cause of periodontal (gum) disease. When the bacteria settle on your teeth they form a whitish film called biofilm. Those that are not removed cause formation of “pockets,” areas of separation between the teeth and their surrounding gums, in which plaque hardens into deposits known as calculus or tartar. The purpose of having your teeth cleaned regularly by a trained professional hygienist is to remove deposits of plaque and calculus. Removal of hard deposits on your teeth is called “scaling.” This can be done either by using hand-held scalers or by newer technology: ultrasonic power scalers.

Let’s take a look at the strengths and weaknesses of both types of dental equipment.

Power Scalers
How they work: These instruments use the energy of ultrasonic vibration to crush and remove hard, calcified deposits of calculus. They also create shockwaves that disrupt bacterial cells. Use of these tools includes washing and flushing the pockets and any exposed root surfaces with water.

Pros: They are as effective as manual instruments for calculus removal in shallow gum pockets and significantly more effective in pockets greater than 4mm. They are very effective in removing calculus from root surfaces and from within periodontal pockets. Their small tips can penetrate deeper into periodontal pockets than manual instruments and are more comfortable to experience, and they are more effective for cleaning difficult nooks and crannies. Coolant sprays flush the area and remove bacteria and their by-products. They require less time than manual instruments.

Cons: A contaminated mist may form so that the hygienist needs to wear protective equipment. The vibration of the ultrasonic instruments may make it difficult to feel if the root surface is completely smooth and free of calculus. Power scalers affect some heart pacemakers.

Conventional Hand-held Scalers
How they work: These depend on the skill and knowledge of the hygienist to manipulate them and scrape away calculus (tartar) from teeth and within pockets.

Pros: They are equally effective for plaque and calculus removal from shallow gum pockets. They do not interfere with electronic equipment like heart pacemakers. They can be used more easily on teeth in which there are areas of demineralization (areas where minerals have been removed from the tooth’s enamel, making it more vulnerable to decay). They are easier on the tooth’s surface and are thus better for use with porcelain or composite restoration, or sensitive teeth.

Cons: They take longer to complete a cleaning. Sometimes they cause more discomfort than ultrasonic scalers.

In most cases the choice of scalers is not really an either/or situation. Most experts say that the best results come through using both types of instruments. As a result, cleanings can be done with effective and efficient outcomes and greater patient comfort.

Four Things You Should Know Before Buying Dental Equipment

Posted on by dentalyoyo520

1.The three-month rule
Tax implications of dental equipment online purchases are significant and should be factored into the decision-making process in a timely manner. Meet with your accountant midyear to track your practice income and estimate end-of-year tax implications. Allow three months to research, view demonstrations from viable vendors, and review pricing quotes before making major equipment purchases of more than $20,000.

2.Investing in core dental function vs. trendy developments
Most last-second impulse purchases involve the latest gadget to create a “buzz” in the profession. Trendy products have a mixed record of success in long-term use and value. Investments in the “less-glamorous” category of core dental function can be a safe and wise investment in the future productivity of your facility. An easily understood analogy is how fathers and teenage sons maintain automobiles.

3.Equipment discounts and trade show specials
I have written about this topic several times and I am always surprised that most doctors remain unaware of the typical pricing structure and product distribution logistics for major pieces of dental equipment.
Manufacturers such as A-dec, Pelton and Crane, Air Techniques, and Sirona distribute their products through networks of resellers. Many manufacturers are very cautious about which resellers they approve to sell and service their products.

4.New facility equipment purchases and “free design”
There are 254 IKEA stores in 34 countries, including 34 locations in the United States. To quote their Web site, the IKEA business idea is to offer a wide range of home furnishings with good design and function at prices so low that as many people as possible will be able to afford them – and still have money left!
