Profin PDX Contra/Angle

The new Profin PDX Contra/Angle is available from Dentatus. Smaller, lighter, more ergonomic and more affordable than its predecessor, the Profin, with safe-sided diamond-coated Lamineer Tips, is the instrument of choice for shaping and finishing hard-to-access areas without damaging adjacent surfaces of all restorative materials, according to the company.

Said Dr. Howard Strassler, professor and director of operative dentistry at the University of Maryland Dental School in the Department of Endodontics, “Although it is the workhorse of any dental practice, a conventional handpiece (that rotates and accepts friction grip and latch-type burs and abrasives) does not meet all the demands of adhesive restorative dentistry.”

Modern dentistry emphasizes esthetics and shaping restorations to consistent clinical standards of form and function. The Profin features precise and directionally controlled movement of a 1.2 mm reciprocating motion. According to the company, it is ideal for delicate and safe shaping, contouring and polishing of natural dentition, as well as for all restorative materials, including composite, cements, porcelain, ceramics, amalgam and metals.

The Profin can be set in a self-steering mode, most often selected for polishing procedures, or a fixed mode, achieved by pushing the tip into one of six notched indexing positions. The fixed position controls directional movement of the tip.

The complete assortment of Lamineer Tips are safe-sided and come with various diamond-coated micron-grain sizes. The largest, 150 micron diamond tips, are used for effectively removing bulky overhangs, while sequentially using the finer grain tips down to 15 microns will produce a very fine smooth finish.

The knife-edge “S-series” offers maximum access and is ideal for creating gingival and incisal embrasures. Smoother finishing is achieved with the Wolfram Tungsten tips, which will not scuff healthy enamel when finishing margins.

Specialty tips are also available for fine finishing of shoulders, chamfers and interproximal reduction.
