Hiossen Implant’s K5 dental unit chair
Hiossen/Osstem Implant’s dental unit chairs, K3 and K5, have surpassed 60,000 units in cumulative global sales, demonstrating strong product competitiveness through extensive clinical use across international markets. This milestone reflects widespread recognition of Osstem chairs for their superior functionality and quality across diverse clinical environments, and underscores the long-term trust they have earned in the global market.
Long-Term Global Performance Across 75 Countries
Since their respective launches in 2013 (K3) and 2021 (K5), the two models have steadily gained sales momentum across North America, Europe, and Asia. Today, K3 and K5 are sold in 75 countries worldwide, with consistent demand in key markets including the United States, China, Russia, Japan, India, Vietnam, and Brazil.
In Europe, K3 has continued to strengthen its market presence. Initially concentrated in several Central and Eastern European countries—such as Romania, Bulgaria, and Poland—sales have recently expanded into major Western European markets including the UK, Germany, France, and Italy, as well as Southern European countries such as Spain and Portugal. This growth reflects increasing recognition of the product’s reliability and performance across diverse clinical environments.
A representative from Hiossen/Osstem Europe commented, “With its robust structure and smooth operation, K3 delivers a stable and reliable user experience. Adoption is expanding across major European markets, with growing inquiries from Northern Europe, including Norway, Denmark, and the Baltic States.”
Globally Validated Competitiveness of K3 & K5
The continued adoption of K3 and K5 across diverse global markets is driven by their robust structural design and advanced functionality, which deliver stable performance across a wide range of clinical environments.
K3 was developed with a focus on strong fundamentals, providing reliable usability in various treatment settings. Its wide height adjustment range and flexible table movement allow clinicians to achieve optimal positioning based on procedural needs. The two-joint headrest enables easy patient positioning without additional button operation during treatment, while the standard shadow-free LED light enhances visibility of the operative field.
Building on the proven strengths of K3, K5 further elevates treatment efficiency and user convenience. Its slim backrest design minimizes knee interference for clinicians, and the lift-up base allows for more precise positioning. The wireless foot pedal reduces cable interference and simplifies maintenance, contributing to a cleaner clinical environment. Additionally, the integrated handpiece air-spray function enhances overall procedural efficiency.
A representative from Hiossen USA commented, “K3 and K5 dental unit chairs are trusted in the U.S. market for their outstanding performance, ergonomic design, and reliable service quality. Their durability and user-friendly features support improved clinical efficiency, which continues to drive strong preference among American dentists.”
