At Dentaltix we have more than 30,000 products for Dentistry and we know the difficulty in finding the tools and complements ideal for each Dentist.
Even more so in the case of students in Dentistry where the bewilderment at this huge variety of brands and characteristics makes it difficult to choose the right ones for their careers!. All this without skimping on benefits but not without paying a premium in specialized instruments, where its complexity will turn against less expert hands.
The most important products for Dental students include articulators and the rotary instruments. In our previous post we told you the basic characteristics that a rotary kit should have and in this post we will delve into the frequent doubts that may arise in your choice.
Whether you already have a rotary kit or if you are thinking about acquiring one we hope to help you, if you have any other questions you can write us and we will help you with it.
Types of rotary connection. What does connection Multiflex, Unifix, Sirona, RotoQuick mean?
The turbines and micromotors receive their power through the coupling, the intermediate unit between the rotary and the hose of the equipment. The different brands have been perfecting their couplings to be faster to assemble and disarm without losing accuracy.
So one of the most widespread connections is the Multiflex® designed by Kavo, most brands have turbines and couplings compatible with this technology and nowadays it is not necessary to pay a huge outlay to have a high performance turbine. Other types of known couplings are the Unifix of the Bien Air brand or the Roto Quick of W & H
We recommend the purchase of a team with a Multiflex connection for students, since being the most widespread, in the future it can be used to improve or extend some of the components without having to renew the complete kit, or in case of failure they are more alternatives and ease in repair.
Another point to keep in mind is that there are different types within each system and are not compatible with each other, A Multiflex LED turbine needs the Multiflex coupling with LED, in the following photo the peculiarities of each system are detailed,
In the coupling there are also different hose connections with different peculiarities, the most widespread in Europe and universities is theMidwest 4, (4 holes) at Dentaltix we also have some kits with Borden connection (2 holes) and to complicate it there are also different Midwest 4 depending on whether the equipment has light or not. A rotary with LED will usually work with a normal hose but will not turn on the light.
If you buy the rotary instruments separately, make sure of the compatibility between them or in the end the search for a small saving can be more expensive!
Rotary Kits... With or without coupling?
On the other hand, there are kits without coupling, this is possible because the rotary with direct connection, mostly with exits, Midwest4 to the hose, these kits are also suitable for students.
To be simplified its price is lower and with proper lubrication they are equally effective, as a negative point when working with patients with them to change the instrument must be unscrewed whole versus the speed provided by a quick coupling.
Rotarys with or without light?
Is it worth paying more for a kit with light? From our point of view ... YES! The first dental practices mark the professional future and an extra help is always better.
The prices have been balanced and the difference is barely noticeable, a better visibility provides greater speed and precision, in addition to avoiding straining eyes or inadequate postures.
An interesting alternative could be couplings with autogenerated light its operation similar to a dynamo of a bicycle provides light at the expense of which the connection to hose has light or not,lighting in any place and situation, ideal for old equipment or dentists with great mobility.
What is the importance of refrigeration in dental rotary instruments?
Nowadays, most clinical protocols require dental treatments always with refrigeration..
Especially with high speed turbines, increasing and avoiding the overheating of the tissues that can cause iatrogenia in the pulp, also help to keep the clinical field clean and clear of waste
All the turbines available on our website include internal cooling, from a simple spray to the most advanced systems with four continuous cooling jets.
In the other part of the kit, the contra-angle or the handpiece, the importance of refrigeration is lower. This is so, since to retouch plaster, prosthesis models or to polish a restoration, cooling is not always adequate. What you should keep in mind here is if you are thinking of the kit as a future investment or just looking to equip yourself with the basic kit sufficient for the university.
What are the most suitable materials of the instruments?
All dental instruments must be made of high quality metal to withstand the harsh clinical conditions and ensure duration after disinfection and sterilization without wear and tear on patients.
Attention!Beware of the acquisition of replicas in instruments, which you will surely find in portals with very cheap products of doubtful origin. In addition to its poor quality and composition of materials, not having the guarantees of the European Union may entail economic sanctions. More importantly, buying these products puts your patients at risk.
At Dentaltix all the kits are made of steel of the best quality. We also have some models coated in chrome alloys to provide the highest hardness and even in titanium, which in addition to strength achieves a weight reduction that facilitates handling and ergonomics.
Whatever the choice may be, all our kits are guaranteed until the end of studies and include free reviews.
Ceramic or Metallic bearings?
The bearings are small spheres that are inside the rotor of the head of the rotary. In the rotor, the cutter is inserted and the rotation is achieved thanks to these spheres. Given the complexity and increasing reduction of rotaries, better materials are needed.
In general, the most common bearings are metallic and the highest quality rotors are shielded or sealed and have an anti-recoil system so that dirt and liquids do not get inside.
The last improvement/advance are ceramic bearings, since the ceramic provides a saving in weight, avoids overheating in long-term treatments and is more resistant to wear than steel.
All these characteristics help to extend the useful life of the instrument, achieve a lower noise and facilitate the handling of the rotary with a better tactile sensation and ergonomics.
