In this episode of Medsider, host Scott Nelson interviews Alfred Griffin, co-founder and CEO of LightForce, a pioneer in fully customized 3D-printed orthodontic braces. Griffin shares his journey from a clinician raised in a family of dentists to a founder building a new category in orthodontics by applying digital design and on-demand manufacturing to traditional braces. The core innovation lies in generating patient-specific braces using a combination of dental scans and orthodontist treatment plans—eliminating the need for reactive adjustments, reducing treatment time by 43%, and cutting visits by 60%. Despite the massive market for braces, Griffin identifies a hidden clinical need: the outdated, one-size-fits-all approach that creates friction for both patients and clinicians. He discusses the challenges of scaling a digital factory, the importance of hiring 'athletes' who thrive in ambiguity, and the critical role of maintaining clinical insight as a CEO. The conversation also covers adoption barriers, investor strategy, and the upcoming launch of metal braces to unlock broader market access. Griffin emphasizes that deep customer understanding is the single most important factor for medtech success.
Customizing braces using patient-specific digital planning drastically reduces treatment time (43%) and clinic visits (60%)
Success in medtech requires solving for clinical, operational, and economic change simultaneously—don’t underestimate adoption friction
Maintain deep customer insight by staying close to the product and user—Griffin still sees patients twice a month as CEO
Scaling a digital factory for mass customization requires talent from robotics, software, and advanced manufacturing—no existing blueprint
Choose investors not just for capital, but for strategic guidance and network; align investor type with your stage (e.g., tech investors early, medtech later)
