Endomotor – Everything you need to know – June 2022 updated

endodontic equipment

Endo Motors with Torque Controls. In recent years, endodontic instrumentation has advanced significantly, with a range of powered rotary and reciprocating systems that can make root canal treatment easier to perform. A major role in this advancement is played by Endodontic Electrical Motors, as they provide clinicians with the ability to use special endodontic Nickel-titanium (NiTi) files.

Why Endomotors are so necessary for modern dentistry?

As we already know, NiTi rotary instrumentation should always be performed with slow-speed and low-torque power. It is practically impossible to provide and maintain a constant and precise torque to the canal being treated when operating manually.

Endo motors offer programmable settings such as digitally controlled speed and torque, automatic reverse functions, and constant power. The ultimate goal is to reduce file breakage and speed up root canal procedures with better overall results.

An endo motor is basically needed for rotary endodontics for RCTs or Root Canal Treatments. It is the modern method for performing root canal treatments in a more efficient and effective way.

Chair Time Reduction – You can save time by using an Endomotor

Chair time is the most important and the most expensive resource of a dental clinic. Many dentists do not account for chair time costs when they do cost analysis. Root Canals are the most commonly performed treatments by the dentist and the endodontist. Endodontics is the primary treatment offered by most dentists. Hence the maximum time of the dentist and the dental clinic is used in Root Canal Treatments.

If you are a clinician who performs endo, you know what it’s like when cases throw you a curveball. On those occasions when something goes sideways, it’s nice to have a few extra options at your fingertips.

Understanding the Torque in Dentistry:

Torque is a measure of how much force acting on an object causes that object to rotate.
In many aspects of practice in dentistry, especially in root canal therapy for root canal preparation, there is a turning force on an instrument. Torque is a parameter that must be controllable in root canal preparation, because different instruments which have been used, seem to need different values of torque.
In root canal preparation, the safety usage of the instrument depends on considering the torque at the failure of instrument.
The instruments are subjected to different torsional torque, if the level of torque is equal to or greater than the torque at failure (fracture), the instrument will separate.
Theoretically, the torque control of endo motors takes into consideration the torque at the failure of rotary instrument.
Torque values lower than the torque at fracture of the instruments can be set on the torque control handpieces.
When a high torque control handpieces is used the instrument is very active and the
incidence of instrument locking and, consequently, deformations and separation would tend
to increase.

An endomotor with speed and torque control is necessary to have complete control over instrumentation. The usual speed range that is employed in endodontics is between 150 and 650 rpm. Higher speeds offer better cutting efficiency but are more likely to cause instrument separation and fracture.

The use of slow-speed high-torque was the accepted form of instrumentation for the past decade. However, evidence shows that there are quite a few iatrogenic errors that occur due to this combination of speed and torque. The new rationale is to use slow-speed low torque instrumentation techniques. A much more preferable parameter would be the use of a specific ideal (right) torque.

As a general rule: Small and lesser taper need Lower Torque values, while Larger and greater taper needs higher Torque value. As a result, the best Endo Motors have full capability to install ad-hoc settings.

The importance of Autofunctions:

Modern endodontic motors are developed with auto-functioning features which make it easier to carry out endodontic procedures and reduce the risk of complications.

Auto Stop, Auto Forward, and Auto Reverse are the functions being incorporated into the latest endo motors. The auto-reverse function causes the rotation of the file to change to the opposite direction when the torque limit is reached. This greatly reduces the load on the rotary file. When the excess load is removed the motor handpiece returns to a normal forward rotation automatically.
If you end up buying an endo motor that lacks the reciprocating function, using a reciprocating rotary file is out of the question. In this scenario, you put yourself at a disadvantage as you are unable to try your hand at reciprocal endodontics. At Dynatech Induatrial, all our endomotors are compatible with the commonly used older generation files.

State of the art: Endo Motors with Apex Locators function! (HERE)

The latest endomotors developed in the current times have an integrated apex locator which eliminates the need for two devices while carrying out root canal treatment procedures. These devices can function as Apex locator and endomotor separately or as a combination of both functions. While using the device in the combination mode, clinicians have the advantage of real-time assessment of the position of the file in the canal.
With the combination of both functions and precise measurements, the clinician can easily cope with the root canal preparation problem and make a perfect root canal treatment.
