When it comes to dental chairs, few brands have made as significant an impact as DCI. With a rich history spanning four decades, DCI has revolutionized the dental equipment landscape through innovative design and an unwavering commitment to quality. In this article, we’ll explore the fascinating journey of DCI and take a closer look at their flagship product, the DCI Edge Series 5 dental chair.

The DCI Story: From Humble Beginnings to Industry Leader

DCI’s story began 40 years ago in the small town of Newberg, Oregon. Founded by the Spencer family, DCI set out to redefine the dental industry by designing parts and equipment that challenged the status quo. Drawing on their firsthand experience—John Spencer as a top dental supplier representative and Janelle Spencer as a dental hygienist—they built DCI into the world’s largest and most trusted dental chair manufacturer.

As the company grew, so did their ambitions. In 2016, DCI launched their own brand of dental equipment called DCI Edge. This marked a significant expansion for the company, allowing them to bring their decades of design expertise and commitment to value directly to dental practices.

The DCI Edge Series 5: Comfort and Innovation Combined

The crown jewel of DCI’s lineup is undoubtedly the DCI Edge Series 5 dental chair. This state-of-the-art chair embodies DCI’s core principles of comfort, reliability, and innovation. Let’s take a closer look at some of its standout features:

  1. Ergonomic Design: The Series 5 features a unique contoured back that provides optimal support for patients while allowing practitioners easy access from any angle. The thin, narrow back design enhances comfort without compromising functionality.
  2. Flexible Positioning: With a dual-articulating headrest and a wide range of motion, the Series 5 enables precise patient positioning for any procedure. The chair’s smooth hydraulic system ensures gentle adjustments and a pleasant patient experience.
  3. Customizable Options: Dental practices can tailor the Series 5 to their exact needs with a variety of upgrades and configurations. From luxurious Ultraleather upholstery to built-in massage functionality, the possibilities are endless.

It’s no wonder that the Series 5 has quickly become the top choice for both private practices and DSOs across the country. By prioritizing both patient comfort and practitioner efficiency, DCI has created a dental chair that truly stands out from the competition.

A Bright Future Ahead

In recent years, DCI’s growth has been nothing short of remarkable. In 2022, they became the fastest-growing dental equipment manufacturer in North America, with the Series 5 chair leading the charge. This success caught the attention of fellow industry leader NSK, who formed a strategic partnership with DCI in 2024.

As two family-run companies with shared values and a customer-centric approach, DCI and NSK are poised to make an even greater impact on the dental world in the years to come. With their combined expertise and resources, we can expect to see more groundbreaking innovations and unparalleled dental chair options for practices of all sizes.


From their humble origins in a small Oregon town to their current position as a dental industry powerhouse, DCI’s journey is a testament to the power of innovation, quality, and customer focus. With the DCI Edge Series 5 leading the way and an exciting partnership with NSK, the future looks brighter than ever for this pioneering company.
