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.
What is a Dental Endomotor?
An endo motor serves as a precision dental device specifically crafted for root canal procedures, offering numerous advantages over traditional manual instrumentation. It stands as a crucial investment for dental practices aiming to enhance treatment outcomes and elevate patient satisfaction. The endodontic endo motor in dentistry is an advanced dental tool crafted to assist in executing root canal treatments with accuracy and efficiency. Its operation is based on the principles of rotational movement and precise control, facilitating the navigation of endodontic files within the root canal.
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 manually maintain a constant and precise torque to the canal being treated when operating.
Endo Motors Torque Is crucial while performing root canal operations. In fact, 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 needed for rotary endodontics for RCTs or Root Canal Treatments. It is the modern method for performing root canal treatments more efficiently and effectively.
How Endomotors Can Optimize Chair Time Reduction?
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 a 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.
Modern Endo Motors provide high-grade flexibility: In contrast to hand instrumentation, endodontic equipment is generally not limited by the file system employed. Except for a reciprocating file system, modern Endomotors can accommodate various file systems. This flexibility empowers dentists to select the most suitable combination for a specific case.
Transitioning from Manual Instrumentation to Endomotors:
The transition from hand instrumentation to endo motors is driven by the desire to overcome the limitations associated with manual methods. Hand instrumentation tends to slow down the treatment process and imposes constraints on the volume of endodontic work achievable in a single day. Consequently, opting for an endo motor that ensures a consistent speed is a prudent decision, allowing dentists to streamline their workflow and efficiently complete more endodontic treatments. An endo motor serves as a precision dental device specifically crafted for root canal procedures, offering numerous advantages over traditional manual instrumentation. It stands as a crucial investment for dental practices aiming to enhance treatment outcomes and elevate patient satisfaction.
What is the Torque in Dentistry?
Torque is a measure of how much force acting on an object causes that object to rotate. Endo Motors Torque Is crucial while performing root canal operations.
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 the 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 instruments.
Torque values lower than the torque at the fracture of the instruments can be set on the torque control handpieces.
When a high torque control handpiece is used the instrument is very active and the
incidence of instrument locking and, consequently, deformations and separation would tend
An endo motor 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 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 tapers need Lower Torque values, while Larger and greater tapers need higher Torque values. 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.
What are the benefits of using Endomotors?
Endodontic motors feature continuous rotary movement, a prevalent characteristic. Rotary endodontics, especially when employing advanced rotary files like Pro-taper or Path Files, has exhibited superior outcomes. This approach diminishes procedural errors, such as file transposition and root perforation.
The fourth generation of rotary files has introduced reciprocating motion, considered to be more potent than continuous rotation. Its advantages encompass extended instrument life, cutting quality comparable to rotary methods, preservation of the original canal anatomy, expedited canal shaping, and reduced dentin crack formation compared to rotary motion.
Speed and Torque Control:
An endo motor equipped with speed and torque control is a crucial function for complete control over the instrumentation process. The selection of speed and torque is contingent on the file system in use: this is the main reason why Endo Motors Torque with adjustable settings are the most popular in the market, nowadays While slow velocity and high torque have been favored historically, there is a shift towards employing low torque for slow speeds to minimize iatrogenic problems.
Auto-Stop and Auto-Forward Functions:
This feature prevents overuse or potential damage by ceasing rotation when a specific resistance level is reached. A convenient feature that enhances procedure efficiency.
Auto Reverse Function:
Auto-Reverse function shifts file rotation in the opposite direction upon reaching the torque limit, reducing the load on the file and preventing instrument separation. It also facilitates a swift return to forward rotation after alleviating the additional load.
State of the art: Endo Motors with Apex Locators function!
The latest, most advanced endodontic motors are equipped with integrated Apex locators. This feature enables the simultaneous use of the endo motor and apex locator, ensuring accurate tracking of the file inside the canal and minimizing procedural errors.
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, dentists can easily cope with the root canal preparation problem and make a perfect root canal treatment.
Always keep in mind: Endo Motors Torque adjustable settings are a crucial feature to consider when approaching a purchase of your next endo motor.
