Lares Research.

Lares Research describes itself as a two-generation, family-owned handpiece company that builds in the United States and sells factory-direct rather than through a dealer network. The about page says that history covers 70 years. It does not print a founding year on that page, so this profile does not invent one. The ISO 13485 certificate and the high-speed instructions both place the company at 295 Lockheed Avenue, Chico, California 95973.

The certificate, issued by Intertek, shows an initial certification date of March 7, 1997, a decision date of February 19, 2026, and validity through March 9, 2029. The scope is design, manufacture, distribution, and service of dental handpieces, couplers, and electric motors and consoles, plus distribution of handpiece accessories. The homepage phone line is 1-888-333-8440, listed from 6 a.m. to 4 p.m. Pacific. The instructions also print 530-345-1767.

High-speed names on the current site are the ProStyle SF, the Legacy 5, and the Xtreme-Power (XP). The swivel instructions say those three are intended for a licensed dental professional to reduce hard tooth structure, prepare cavities, and do restorative dentistry. They connect to a KaVo MULTIflex LUX coupler or an NSK swivel coupler. The store category lists a fixed-back ProStyle SF for offices that do not use a swivel. Burs in the instructions are friction-grip, with a shank diameter of 1.59 to 1.60 millimeters. Recommended length is 19 millimeters. The stated range is 16 to 21 millimeters for 557 models and 19 to 25 millimeters for 757 models. The sheet marks the handpiece as not sterile, so it has to be processed before use.

Electric and low-speed products are on the same homepage. Smoothdrive covers 1:5 and 1:1 contra-angles and an electric motor system. Pastel Plus is the prophy handpiece. Perfect Finish is the low-speed restorative system. MULTIFORCE is a 5K low-speed. Pastel disposable prophy angles and prophy paste are listed as their own items. Accessories and genuine factory parts are separate headings, which matches a company that says it services what it sells.

Lares tells buyers it has stayed independent and has refused the dealer channel. That is a purchasing fact, not a performance claim. You order from Chico, and you ask Chico about turbines, loaners, and turnaround. Offices that prefer a local dealer to stock a KaVo, NSK, or Bien-Air turbine should compare that service model on purpose. The handpiece still has to match the coupler and the bur already in the cassette.

Lares suits a general or restorative practice that wants to buy high-speed handpieces from the factory and keep a direct line for parts. A swivel ProStyle SF, Legacy 5, or Xtreme-Power can go on a KaVo MULTIflex or NSK coupler the office already owns, which is the compatibility sentence in the instructions. A fixed-back ProStyle SF is the version for a non-swivel connection. Read the air and electric handpiece guide before you standardize one model for every room.

Hygiene departments are a different order. Pastel Plus and the Pastel disposable angles are prophy tools. They do not prepare crowns. The disposable prophy angle guide is the comparison for the angle, not for the high-speed. Electric users should look at Smoothdrive only after they know whether they need a 1:5 increasing angle, a 1:1 angle, or the motor and console together.

Labs are not the primary Lares buyer described on the site. The instructions limit the high-speed to dental treatment by a licensed professional. A denture lab's bench handpiece is a different machine.

The useful comparison is the sales channel and the coupler, not a horsepower ranking. KaVo, NSK, and Bien-Air are other handpiece manufacturers in the equipment directory. Lares says it sells direct and remains family owned. Those companies are commonly bought through dealers. A Lares swivel is designed to fit KaVo MULTIflex LUX and NSK couplers, which means the hose you have may matter more than the logo on the handpiece.

Do not treat an air-driven high-speed and a Smoothdrive electric angle as the same purchase. The handpiece guide separates them. Electric adds a motor and a controller. Air uses the delivery unit's drive air. Mixing the two without checking the tubing is how offices end up with a handpiece that will not seat.

Prophy angles are a third comparison. Pastel disposables compete with other single-use angles in the prophy guide. They are not a reason to choose the Legacy 5.

Confirm the coupler before you order. Swivel instructions name KaVo MULTIflex LUX and NSK. The fixed-back ProStyle SF is the non-swivel option on the Lares store. Then match the bur: 1.59 to 1.60 millimeter shank, with the 557 and 757 length ranges printed in the instructions. A short bur the sheet tells you not to use is an avoidable failure.

The handpiece ships not sterile. Build it into the office instrument cycle before the first patient. Ask Lares for the current sterilization instructions, the turbine replacement policy, and whether a loaner is part of a repair. This profile does not state a warranty term because the pages reviewed did not print one. Get it in the order acknowledgment.

The ISO 13485 certificate is valid through March 9, 2029, and its scope includes service. That supports the factory-repair story. It does not tell you the turnaround time from your city to Chico. Ask. If you are also buying disposable prophy angles, order them as a supply, on a different cadence from the high-speed.
