Rototome® Schematic

Rototome®

A revolutionary concept based on the best practices in implant dentistry.  Rototome® instruments give control back to the surgeon.  Control of dental implant osteotomy depth, rate of expansion, rate of advancement, trajectory, bone density, and ultimately implant stability; while reducing patient trauma during surgery, and complications for the provider.   The simplicity of the design results in a practical, durable, and elegant solution that should be in every implant surgeons armamentarium .    ​  

Designed with compatibility in mind, protocols have been developed for many implant systems* including: Biohorizons®, Camlog®, DENTSPLY ASTRA TECH®, Hiossen, Implant Direct ® Sybron, Nobel Biocare®, and, Straumman®, Zimmer ®. 

Who We Are

Established by a clinician and a mechanical/manufacturing engineer.  Janus Dental Industries is the embodiment of practicality through design.  Studying the existing technology, clinical/scientific evidence, and procedural work-flow guided us in the development of our products. We produce the highest quality products to enhance your services and improve your practice.

Our History

In 2010, unsatisfied with the technology currently available, we studied and designed a device capable of expanding bone, condensing bone, and elevating sinus membranes with less trauma to the patient and more control than was available with mallet type or screw type osteotomes already available.  In 2012 the first instruments of what would come to be known as Rototome® instruments were created. 
  
We wanted to ensure  a high quality product, that we'd be proud to stand behind.  To do this we insisted on the best quality materials available and made certain to keep the manufacture of our instruments domestic.  Our instruments are Made in the USA, from high quality 440 Stainless Steel, which has been heat-treated to ensure longevity of the working elements.

Depth control: The thread pitch is set to ensure precise advancement per rotation, accurate to 0.5mm.  The pitch is matched to each instrument so that the you the surgeon can focus on surgery; regardless of diameter every instrument will advance the same amount per rotation!  Vertical lines on the shank of the instrument assist you in identifying each half rotation of the instrument, without you needing to shift your eyes from the surgical field.

Rate of Expansion: Because bone is pliable, living tissue, it is capable of compression and expansion; however, when the manipulation is uncontrolled the outcome treatment is unpredictable.  While many ways of assessing bone density have been described the flexibility and relative hardness vary considerably between individuals. Experienced surgeons understand that the only way to truly know how bone will actually behave is during surgery.  Due to the measured rate of advancement and the surgeons direct tactile interface with the instrument, proper feed-back is obtained and the operator can adjust the rate of advancement and therefore expansion.  By controlling the rate of advancement two concepts are permitted 1) Interstitial fluid pressure resulting from compression is able to dissipate reducing hydrostatic back-pressure and 2) Unfavorable outcomes can be identified as they are developing and managed prior to completion.  

Trajectory:  Because final angulation of the implant is important to the prosthetic outcome, control of the direction of the osteotomy is critical.  From time-to-time, optimizing the position and angle of the implant requires the initiation of the osteotomy at a different angle than the final angle, with a redirection as the procedure continues.  With class I lever mechanics, a direct user-interface in the long access of the instrument, and a clear visual reference to the direction of the osteotomy, the surgeon has the best control of final osteotomy trajectory. 

Bone density and Stability:  As a result of the non-cutting action, the bone is compressed rather than removed.  The compression reduces the medullary space and consolidates the trabecular bone, resulting in an osteotomy with a denser bone side wall than a drilling protocol.  This denser bone will then be able to interface directly with the implant on placement, creating more bone to implant surface contact and allowing for increased primary stability.
