Milestone Scientific develops and sells computer-controlled drug delivery systems designed to make injections more precise and less painful. The core technology, called Dynamic Pressure Sensing (DPS), controls flow rate and measures pressure at the needle tip in real time, allowing the device to identify tissue types and deliver drugs at the precise target location. Milestone operates two segments: dental and medical. The dental segment drives the vast majority of revenue and is built around the STA Single Tooth Anesthesia System (marketed as CompuDent and The Wand), a pen-like device that delivers local anesthetic with less pain than a conventional syringe. The medical segment centers on the CompuFlo Epidural System, which helps anesthesiologists identify the epidural space through real-time pressure feedback. Milestone's business model combines one-time instrument sales with recurring sales of single-use disposable handpieces — each injection requires a new disposable, creating a recurring revenue stream tied to utilization. Milestone sells dental products in the U.S. directly through an e-commerce portal and internationally through exclusive distributors. The medical business is sold through a direct sales force and independent agents in the U.S. and distributors internationally. Dental penetration remains low at roughly 1.5–2% of the domestic market. The medical segment is in early commercialization, and broad adoption depends heavily on expanding Medicare reimbursement coverage, which has so far been established in Florida, Texas, and New Jersey.
