About Us

Since 1983, the company's centerline philosophy has been to design and manufacture castable spherical attachments with a connecting nylon female component being processed into the removable prosthetic device. Mr. Ezio Nardi, founder of the company, pioneered this simple concept of ball and cap connectors. Over the past 30 years, this technology is the proven standard for RPD's and overdenture prosthetic design, improving superior oral health, functionality, esthetics and patient comfort. Today, Rhein83 is recognized worldwide for its technical expertise in spherical dental attachments, superstructure frame designs, and direct implant abutments.

Smart Products With Purpose

This year, Rhein83 has brought to market several new high quality products for the dentist and dental laboratory with it's primary focus centered on implantology, under the direction of Gianni Storni, VP Technology.Mr. Storni and his technical group have a clear approach. "Does it make sense, will the product offer a solution for the dental team's daily challenges, and be a cost effective treatment plan." This fundamental idealogy goes into every new design concept for product development and manufacturing, and is most essential for Rhein83.


The new OT Equator 3 in 1 attachment system, introduced at the 2009 Rome Expo, is an example of this engineering distinction. By vertically reducing the classic OT Cap 2.5 mm sphere to its "equator," the low profile elastic caps use only the bottom half of the sphere, achieving equal functionality and retentive values as its predecessor.The OT Equator line offers the lowest profile and has the least overall displacement of any attachment system on the market, giving the dentist and the technician superior case design options for esthetics and function, especially where space is limited.

Experienced Team Approach

Strong factors that contribute to the continued success of Rhein83 srl and Rhein83 USA are having extremely knowledgeable "live" customer service and technical support team personnel. Even in today's high-tech society of clicks and voice prompts, consumers still prefer to speak with a friendly voice that can assist them quickly with accurate information.Fielding customer phone calls can be as easy as taking an order for replacement caps or as complex as having to provide viable clinical solutions for a multifaceted inherited old case, with divergent implants having little or no information regarding the fixtures, and everything in between.
