Digital orthodontic workflow is reshaping how orthodontists diagnose, plan, and deliver treatment — and few practitioners understand it as thoroughly as Dr. Melissa Shotell, a board-certified orthodontist whose career has been defined by the intersection of technology, education, and interdisciplinary care. In this episode of The Technology Evangelist Podcast, Dr. Shotell joins host Dr. John Flucke for a wide-ranging conversation covering everything from why intraoral scanning changed the clear aligner market forever, to what’s really involved in 3D printing an aligner in your office, to where AI fits — and where it doesn’t — in a sound digital orthodontic workflow.
Key Insights on Digital Orthodontic Workflow and Clear Aligner Technology:
- A Lifetime in Dentistry, Starting at Age Four: Dr. Shotell’s interest in dentistry began at a preschool field trip where she was the only child who volunteered to play the dentist — a moment her teacher later commemorated by presenting her mother with photographs at her dental school graduation. Her personal experience as a patient deepened that passion: bilateral supernumerary teeth and impacted canines required complex interdisciplinary treatment from age seven to fifteen, involving an orthodontist, a pediatric dentist, and an oral surgeon working in close coordination. That early exposure to what skilled specialists can accomplish together shaped her entire approach to collaborative, team-based care.
- Four Years in General Practice Before Orthodontics: Rather than going straight from dental school into an orthodontic residency, Dr. Shotell practiced as a general dentist for four years — including time in an Ohio multi-specialty office alongside in-house orthodontics, periodontics, and oral surgery. She performed implant planning and cosmetic bonding for post-orthodontic cases, giving her a practitioner’s-eye view of how the disciplines interact. When she did return to school, she completed her orthodontic certificate and master’s degree at Loma Linda University — which she notes was the first university in the United States to implement cone beam CT technology.
- Intraoral Scanning Unlocked the Clear Aligner Market: Dr. Shotell makes a clear case that intraoral scanning — more than any other single development — is responsible for the explosive growth of clear aligner therapy. Before digital scanning, the workflow required full-arch polyvinyl impressions that could take days to reach the lab, only to come back rejected. Rather than keeping impression materials as a fallback when she first introduced a scanner into her practice, she locked all polyvinyl and alginate in a cabinet over a weekend, leaving the team with only the scanner on Monday morning. That baptism-by-fire approach forced full adoption and established a true digital orthodontic workflow from day one.
- The Dental Treadmill: Technology That Sits in the Corner: One of the most useful frameworks Dr. Shotell introduces is the “dental treadmill” — the piece of technology a practice buys with good intentions, uses once or twice, and then abandons. The pattern is especially common when the doctor is the only person trained on a new system and hasn’t built it into anyone else’s responsibilities. Her prescription: a team-wide meeting before implementation, with lunch, to walk through the benefits, the concerns, and each person’s role. Practices where everyone is trained and bought in adopt technology quickly; practices where only the doctor was trained rarely sustain the change.
- 3D Printing Is Not an Easy-Bake Oven: When asked what holds dentists back from implementing 3D printing, Dr. Shotell points to the gap between expectation and reality. Many clinicians envision a simple scan-to-print pipeline; the actual digital orthodontic workflow around resin-based printing involves a dirty alcohol wash, a clean wash, and a UV light curing step — with wet, uncured resin on surfaces at every stage. She recommends disposable clinic jackets in the printing area and advises against wearing anything of value. Beyond the mess, she emphasizes that buying a 3D printer really means buying and implementing an entire system — printer, wash units, curing unit — and that space planning and team training matter as much as the hardware itself.
- Direct Print Aligners: Still Early in the Race: A significant section of this digital orthodontic workflow conversation focuses on the difference between thermoplastic and directly printed clear aligners. The two primary direct print systems currently available in the United States — Graphy and Lux Creo — each require distinct and time-intensive post-processing. Graphy uses a centrifuge to remove excess resin, followed by nitrogen-environment light curing; Lux Creo uses a proprietary two-solution wash system and a drying oven before light curing. When these steps are timed out against efficient thermoforming workflows, Dr. Shotell finds the time savings of direct printing are smaller than expected. She also flags case selection as a key variable: patients who brux or clench heavily may wear through a mono-layer printed material faster than a multi-layer thermoplastic aligner designed with a harder outer layer.
- AI in Orthodontics: Speed for Setups, Not a Substitute for Judgment: AI is already embedded in the in-office aligner design tools Dr. Shotell uses, with platforms like ArchForm generating automated treatment setups that the clinician then refines — compressing what once took four or more hours of manual tooth-by-tooth segmentation into roughly ten minutes. But she draws a firm line around clinical judgment: no aligner company, AI system, or laboratory will ever tell a doctor they shouldn’t treat a particular case. The AI will always generate a solution. The professional’s role — examining the proposed setup and asking whether those teeth will actually move the way the software predicts — is irreplaceable in any sound digital orthodontic workflow.
- The “Movie” Trap in AI-Driven Treatment Planning: One of the more memorable cautions Dr. Shotell raises involves the animated tooth-movement simulations that all major aligner software produces — polished, three-dimensional movies showing exactly how the AI expects the teeth to shift over the course of treatment. These animations represent a calculated prediction, not a clinical guarantee. She cautions clinicians, especially those newer to digital orthodontic workflow, not to let a compelling simulation substitute for clinical reasoning: the movie shows what the software solved for, and it may not reflect how the teeth will actually respond.
- Aligner Bee, Learn Dentistry, and the Name Behind the Brand: Dr. Shotell teaches digital dentistry, orthodontics, 3D printing, and in-office clear aligner workflows through her platform Learn Dentistry, and is active on social media under the handle @alignerbee. The name has a personal origin: Melissa is derived from the Greek word for honeybee, and her father — who is 100% Greek — chose her name specifically for its meaning. She originally adopted the social media name so her patients wouldn’t recognize her at conferences. It has since become recognizable enough in the orthodontic community that she is sometimes identified in person by the handle before her given name.
What Dr. Melissa Shotell makes clear throughout this conversation is that mastering a digital orthodontic workflow is not about any single piece of technology — it’s about understanding how scanning, 3D printing, aligner design software, and AI each fit into a coherent, team-supported system, and knowing where each one genuinely helps versus where clinical judgment still has to lead. For orthodontists and general dentists curious about where to start, what to avoid, and how the most experienced practitioners are actually using these tools today, this episode is an essential listen.
