What's Difference Between Turbine And Contra Angle Handpiece


The advantages of the dental turbine handpiece are its simple and robust structure, sturdiness, lower purchase price and lighter weight. However, over the years, the adverse effects of high frequency sound from turbines on operator hearing have become an important issue.

In contrast, electric motors are quieter than turbines and cause less hearing damage. When considering the quantity of tooth material removed per unit of time, it is clear that electric motors with water cooling are superior to turbines for grinding.

With the continuous development of electric motors in recent years, manufacturers have clearly recognized that the ergonomics of the weight and size of dental handpieces plays a decisive role in purchasing decisions. The reduction in weight and size is significant compared to instruments manufactured in the past three to five years. It is not uncommon to have a weight reduction of up to 30% and a size reduction of up to 15%. This improvement is due to the reduction of ISO accessories on the motors.

Please note that the "shortened endodontic contra angle handpiece" can only be used on motors with a reduced E-fitting. Even with the overall trend of weight reduction, the turbines are still smaller and lighter than the contra-angle handpiece systems power by the electric motors.

What causes cavities? And how to prevent cavities ?

图片
What causes cavities? Dental cavities, or caries, are tiny holes in the hard surface of the teeth. They are caused by bacteria on the surface of teeth creating acid out of sugar. The most common culprit is a bacterium known as Streptococcus mutans. The bacteria form a sticky film known as plaque. The acids in plaque remove minerals from (demineralize) your enamel — a coating of the teeth made mostly of calcium and phosphate. This erosion causes tiny holes in the enamel. Once the acid damage spreads into the dentin layer underneath the enamel, a cavity forms. How to prevent cavities? 1. Sugar-free gum Sugar-free gum containing a compound called casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) has been shown to reduce S. mutans even more than xylitol-containing chewing gum. You can find this type of gum in stores. 2. Vitamin D Vitamin D is important to help absorb calcium and phosphate from the food you eat. Studies show an inverse relationship between eating f...

How Long Will Dental Implants Last?

图片
Dental implants are one of the biggest innovations in modern dentistry. They are true prosthetic replacement teeth and consist of artificial titanium roots with a porcelain crown. More than 3 million Americans have dental implants with dental implant machine , an increase of 500,000 people a year. As dental implants become an increasingly popular alternative to missing teeth, we will ask: How long does the dental implant last? The short answer is that dental implants can last a lifetime. And here is a long answer. Anyone who has to replace a crown or bridge or reinstall a denture knows that not all dental restorations will last forever. All three types of restorations may fail for their own reasons. In the case of crowns and bridges, if the original tooth structures to which they are attached are damaged by decay, they may fail. When bone loss causes the jaw to change shape, most dentures eventually need to be reinstalled or replaced. It is lucky for you to get dent...

Smile Builders: Leader of Dental Tourism in Mexico

Mexico City. A few days ago, our Smile Builders Mexican dentist Ricardo Guevara met with Mexican Tourism Director Miguel Torruco Marques to discuss the importance of dental tourism in Mexico and how Smile Builders can help patients from all over the world with their oral health. Based on statistics from patients surpassing borders, Mexico attracts 422,000 to more than 1 million foreign patients each year in 2017, many of them from California, Arizona and Texas. However, due to the absence of waiting time in Mexico, patients in Canada and the United Kingdom also like our region very much, compared to their country’s oversaturated public health services. The Minister of Tourism explained that the agency aims to incorporate the voices of Mexico’s medical tourism business, the most representative actors in the academic and social fields, to integrate diversified and inclusive proposals to develop sectoral policies that can transform Mexico. The power that should be gained in the wor...
