One of the most essential tools for the success of dental treatment is a good dental handpiece. Reading this article will help you make a well-formed decision when choosing your handpiece. An efficiently running dental clinic must have a high-performance reliable, quality dental handpiece. A good quality dental handpiece will not only increase productivity but will also reduce stress, effort, and running costs. It can save lives!
On choosing your dental handpiece you have to make sure that it's a compliant product and make sure you made your purchase from a trusted source. Be cautious about the internet as it is filled with low-quality and sub-standard non-compliant dental handpieces. I know that those bargains may be very tempting and eye-catching but you have to be smart enough not to risk your reputation and your patient's safety for the sake of money you will regret it in the long term. A quality dental handpiece might be a bit costly but it's a good investment. The cost of your handpieces over a certain period, say 2 to 4 years, the initial purchase cost, the warranty, the service cost, and the quality of the after-sales service are these all-important factors that you have to take into consideration while making your decision. The best handpieces to choose from are compliant, and suitably priced, with a warranty and a capped-price service from a reputable aftersales service department.
High-Speed Handpiece
High-speed handpieces are often called turbines working in conjunction with a bur it is considered a rotary instrument as it mainly works by cutting into the tooth structure (like a drill and a drill bit). The bur (rotary cutting tool) is usually rotated by the handpiece at speeds ranging between 200k rpm and 450k rpm, that's why it is called high-speed!
The main function of the high speed as a medical device is to cut through the tooth structure efficiently to prepare it to either receive a restoration or to be capped with a crown it might as well section the tooth to be removed during a dental surgery an efficiently working bur and a good quality handpiece can almost cut into anything. The shank of the bur used with a high-speed handpiece is approximately between 1.59–1.6 mm.
A great amount of heat is produced from the high speed of the bur which may affect the health of the pulp tissue that's why a cooling water spray must be incorporated within the highspeed handpiece to prevent any overheating that might occur. The best high-speed handpieces are those which deliver the cooling spray via three spray ports thus producing fewer aerosols than other handpieces with four or more spray ports which may contribute to limiting the spread of infection throughout the dental treatment.
Highspeed handpieces are entirely air-driven. They might also exist If you're willing to work in a posterior area or if you're willing to work for a child highspeed handpiece with smaller head sizes is the right choice for you as they improve visibility and provide a better access area Whilst if you willing to do a superfast dental procedure high-speed handpiece with larger head sizes will be definitely of great help as they produce more torque and cutting power thus they can be very time saving for the dentist. The next time you purchase your highspeed handpiece try to choose the ones that achieve the perfect balance to deliver quality performance, the low noise level at a suitable size which allows good visibility and access for all dental procedures. Don't forget to choose the one that is suitable for your dental chair as well!
Low-Speed Handpieces
Low-Speed handpieces are sometimes called contra-angles, straight pieces, or attachments. a 2.35mm OD bur is generally used with low-speed handpieces (like the high-speed, the drill, and a drill bit). An air motor that is an air-driven or electric drive is usually connected to the low-speed handpiece. This air motor determines the rotation speed of the bur as well A 1:1 ratio low-speed will rotate the bur maximumly at 40K rpm if attached to an electrically driven motor and approximately. 20K rpm if attached to an air-driven motor.
Removal of soft decayed dental tissues, finishing cavity preparation, polishing, trimming and prophy work can be done efficiently using a low-speed handpiece. Various models of low-speed handpieces are available each one has a different function according to its model for example straight handpieces are primarily used for surgical procedures and extraoral procedures such as denture trimming. Low-speed contra handpieces can be used to remove soft decayed dental tissues, finish and polish restorations, refine cavity walls, and adjust crowns, bridges, and dentures. It can also be used for prophylaxis work that's basically when you want the prophy cup or bristle brush rotating slowly. Contra angle handpieces can be provided in various speeding ratios either increasing or decreasing according to the treatment procedure being performed.
