Endodontics is the branch of dentistry that deals with the inside of the teeth. It is a challenging specialty and requires meticulous attention to detail along with excellent hand-eye coordination.
There are many different types of endodontic rotary systems available in the market, all serving different functions. In order to select the right endodontics rotary systems for your practice, you will need to understand your individual needs and workflow processes, as well as various features that may be beneficial for you.
What are the different types of endodontics rotary systems?
Endodontic rotary systems are designed to accommodate a variety of endodontic procedures. There are three main types of endodontics rotary systems: The first type is the most commonly used type and is used for most extractions and coronal preparations. This type can be further separated into two subtypes – rasp-type and diamond-type. The rasp-type is used for extracting teeth, while the diamond-type is used for cutting away excess dentin from a tooth preparation before fitting a filling material.
The second type is used for root canal therapy or root canal restoration. It’s also called an apical file system because it’s mainly used in root canal therapy or root canal restorations that involve shaping the canal with files and then sealing it off with temporary filling material like gutta percha or gutta-percha points. This type of system requires more time and patience than the other two types of systems, as well as detailed knowledge of anatomy, anatomy of periodontal tissues, and microbiology.
The third type is mainly used in surgical procedures such as dental implant placement surgery or bone grafting surgeries. It’s also called a surgical file system because it consists of many different files that are each specifically designed to accomplish different goals during these messy surgeries that often require opening up the bones on either side of the mouth.
How do you choose the right endodontics rotary system?
The first step in choosing the right endodontics rotary system is to understand the various options available. The following discussion will help you determine which one is right for you. First, let’s take a look at the handpiece. Endodontic handpieces are available in two different types: electric and air-driven. Electric handpieces are connected to an electrical power source and produce more torque than an air-driven system; however, they are also heavier and more expensive. Air-driven systems offer more versatility than electric ones as they can be used for both endodontics and general dentistry.
Next, you need to consider the type of tip that comes with the handpiece. Endodontic tips come in many shapes and sizes depending on what type of tool is being used during treatment. For example, a standard round dental burr has a small round opening whereas a tapered root canal file has a larger opening at one end that narrows towards the tip of the file.
When deciding on your endodontics rotary system, it is important to know what type of files you will be using most often so you can select one that comes with those specific types of files. Last but not least, there’s the
Types of the endodontic rotary system: Disc Cutter
Endodontic rotary systems may be classified into three main types: disc cutter, diamond-tipped, and rotary NiTi. Disc cutters are composed of a series of discs that are used to see root canals. These discs have serrations on their cutting edge which helps the disc saw more smoothly in the root canal. Discs are available in various sizes to accommodate different sizes of teeth, and they come in sets of 3 discs with varying diameters (6mm, 8mm, 10mm).
Diamond-tipped endodontics rotary systems are composed of a small number of large-diameter files connected together at their pointed end by a handle. The use of these files is typically limited to access preparation and shaping.
Instead of using hand force alone to move them, these instruments use rotation speed instead to move the file holder up and down along the externally threaded screw. There are two types: one is manually operated while another is motorized.
Rotary Disc System
The flexible shaft design allows the operator to access tight spaces, such as deep in the canal, with ease. These systems are simple and easy to use. Which makes them great for use in crowded endodontic offices. Where staff training may not be adequate.
They are available in two forms:
– A cordless model which is battery operated and can be used while sitting or standing
– A corded model that plugs into an electrical outlet. The rotary disc system is comprised of two discs on either side of the root canal instrument. These discs are made of a flexible material and have teeth (usually serrations) to grip onto the root canal instrument.
