The use of Dental handpiece

The present invention relates to a handpiece for dental use, and more particularly, to a handpiece to be used by a dentist for cutting or drilling a root canal of a tooth.

In forming a root canal of a tooth, a dental reamer or a dental file (hereinafter referred to as “cutting tool”) is generally used. The cutting tool may be operated manually or with use of a handpiece with a drive mechanism. With these cutting tools, a spiral cutting edge is inserted into a root canal, and the back and forth movements or rotational movements of the cutting tools by changing the cutting tools corresponding to the shape of the root canal allows the root canal to be tapered. To cut a root canal, a handle of a cutting tool is held for manual operation, or a cutting tool is connected to a dental handpiece for using rotationally driving force of motor or the like.

Since a dental reamer has a large lead, that is, a relatively gentle spiral cutting edge, it is mainly used for cutting by rotational movements. In contrast, a dental file has a spiral cutting edge having a lead smaller than that of the dental reamer, therefore, it is mainly used for cutting through back and forth movements like a file. Further, the dental file is often used by incorporating the back and forth movements as well as some rotational movements at the same time, which allows a root canal to be cut by the back movement and debris generated by the cutting to be carried away to outside of the root canal through spiral channels of the edge portion.

A dental handpiece heretofore in use for operating these cutting tools is sometimes capable of driving the tools like ultrasonic scaler both by the back and forth movements and by the rotational movement. “The back and forth movements” means the movements of the cutting tools for cutting by the back and forth movements, that is, reciprocating movement in a longitudinal direction of the cutting tools.

In a dental handpiece in the past, when an edge portion of a cutting tool is caught by a curved portion of a root canal or the like, the cutting tool does not progress further from the caught portion and stays there, therefore, only a head of the dental handpiece relatively goes up and down, which causes the root canal not to be cut at all.

Something About Dental Implants

You might have come across advertisements claiming that you can get your lost teeth back. This is true and is now possible thanks to implant dentistry. Implant dentistry is a branch of dentistry which deals with makeover and cosmetic dental procedures. Dental implants are artificial teeth that are placed into the jaw bone to replace lost teeth – both in terms of functionality and appearance. They are highly advantageous and effective. If you’ve lost your teeth and want to get them back, dental implants are the way to go. They used to be very costly, but with time they’re becoming more and more affordable and provide very effective results.

The field of implant dentistry is already very developed. In fact, modern dental implants were invented 50 years ago. Implants are commonly made from titanium and it is the dental handpiece of choice because it has very unique properties. First and foremost, it is very tough and can withstand the intense strain that normal teeth have to bear. Secondly, titanium is biologically compatible. This means it will not cause damage to biological tissues and won’t be rejected by the body’s immune system. Plus, titanium and jawbone integrate well, a phenomenon which is called Osseo integration.

The year 1965 is considered to be the year when the Birth of Modern Dental Implants happened. This was the year when Dr. Branemark first used a titanium dental implant into the jaw bone of a human volunteer. With the success of the first titanium dental implant, the process of studying the implantation of titanium into human bone for missing teeth options was started in earnest – and with more depth and intensity.

Since the ancient times, there have been countless advances with regards to the technologies used in dental implants, and in addressing missing teeth concerns. The evolution of this technology makes it possible for people nowadays to enjoy the benefits of dental implants that are highly effective, long-lasting, and which can be placed with minimal discomfort and inconvenience to the patient.

Missing Teeth Options Today
There are a number of missing teeth options and dental equipment uk available today, with each option having the goal of replacing the form and function of teeth that are lost.

Dental Implants – These are titanium screws that are surgically embedded into the jaw bone, and will then serve as a base where tooth restorations (such as a dental crown) will be attached to. These implants effectively replace the form and function of missing teeth.

Removable Dentures – Can be full (to replace a full arch of missing teeth) or partial (used to replace several missing teeth that form a part of the full arch). Dentures can be removed whenever necessary (for example, for cleaning purposes); however, since they are not permanently attached to the jaw bone, they may have a tendency to move around and cause discomfort to the one wearing them.

Dental Bridges – Also called fixed partial dentures, dental bridges are a series of dental crowns that will replace the form and function of several missing teeth. A dental bridge is permanently attached to the remaining natural teeth, which surround the area where tooth are missing.
