Effortlessly match the appropriate magnification level and field size for each procedure using the OmniOptic loupe system from Orascoptic

Many years ago, while still in dental school, my mentor, Dr. Harold M. Shavell, told us, “No one should be allowed to graduate from dental school without a 35-mm camera and a set of loupes!” After all, you can’t do what you can’t see. The year was 1979. While the use of magnification in den­tistry has certainly grown over the years, it is still not considered a standard of care by all dentists. But since we work in a clinical discipline where the difference between success and failure can be measured in tenths of millimeters or less, it makes absolutely no sense to perform dental procedures without the aid of mag­nification. Furthermore, most of us perform a variety of procedures, and the more exacting or focused the treatment is, the more important it is to have greater magnification for optimal visual acuity.
Orascoptic’s OmniOptic system allows me to easily match the most appropriate magnification power and field size to each specific procedure. It is the first loupe system that combines a customized frame with a selection of telescopes of varying magnifications (2.5x, 3.5x, 4.5x, and 5.5x magnification power). 

The OmniOptic system allows us to conveniently change the magnification as a procedure dictates, rather than having an inventory of loupes with different magnifications where the entire loupe and frame need to be removed and replaced each time a change in the power is desired. The frame is customized to the:  
•    Interpupillary distance and optical center—this determines the location of the telescopes on the frame
•    Declination angle—this determines the angle/tilt of the telescopes
•    Eye prescription, with or without bifocals.
The telescopes are customized to the individual’s comfortable working distance chairside at an ergonomically comfortable position from the patient’s oral cavity.

Application-Specific Views
With a generous 4+ inches of field size, 2.5x magnification is perfect for hygiene procedures, oral cancer screenings, and many quadrant-focused procedures. The 3.5x or 4.5x magnifications are ideal for individual teeth to check and refine margins, to examine tissue prior to master impressions, or during cementation of porcelain veneers or crowns.
The 5.5x can enhance efficiency during endodontic procedures, such as locating the canal orifice prior to instrumentation. I also found it helpful for laser dentistry—to better visualize laser-tissue interaction during cutting procedures—and for surgical procedures, such as extractions or implant placement/restoration where pinpoint accuracy is critical.


Accommodating 4 magnification powers ranging from 2.5x to 5.5x, the OmniOptic is an ideal system for users looking to increase their magnification power over the course of their career. The unique design features a magnetic anchor built into the carrier lens of the frame, allowing clinicians to upgrade their magnification power without having to succumb to the process of ordering a new loupe.
