3D Printing in Dentistry: Applications and Materials

3D printing in dentistry has moved well past proof-of-concept. It’s a production technology now — one that reshapes lab workflows, shortens patient chair time, and, in the right setup, reduces per-unit costs. The question for most practice owners and lab managers isn’t whether it works; it’s which applications justify the investment and which materials are actually cleared for clinical use.

What 3D Printing Is Used For in Dentistry

The range of outputs is wider than many clinicians expect. According to a 2024 review published on PMC/NIH, dental 3D printing is used in the production of implants, surgical guides, crowns, inlays, onlays, overlays, prostheses, custom models, aligners, and even some surgical instruments. That’s not a niche list — it covers nearly every clinical discipline.

Surgical Guides

Printed surgical guides are among the most clinically validated applications. A scoping review in Clinical Oral Implants Research identified three main implantology use cases: customized implants, surgical guide fabrication, and implant-supported prostheses including metallic frameworks and ceramic or polymer superstructures. Guides reduce the number of instruments needed intraoperatively and improve placement accuracy — which is why guided implant surgery has become a standard workflow in many implant-focused practices.

Dentures and Prosthetics

Digital dentures are one of the clearest efficiency wins. Prosthetic dentistry research has found that fully digital denture workflows — using 3D printing, milling, or a combination — can cut the number of required patient visits from as many as five to as few as three. (The specific study referenced in earlier versions of this article as appearing in the Journal of Prosthetic Dentistry could not be confirmed with a retrievable citation; readers are encouraged to consult that journal’s digital workflow literature directly for primary evidence.) Savings compound further when practices switch to 3D-printed denture teeth. For patients with anxiety or mobility issues, fewer appointments isn’t just convenient; it’s clinically meaningful.

Pediatric Applications

Worth flagging separately: pediatric dentistry has seen rapid uptake. Because young patients often have limited tolerance for long appointments, digital workflows that reduce chairside time and total visit count offer a practical advantage that goes beyond cost.

Technologies: Why SLA and DLP Lead

Several 3D printing technique families apply to dentistry — vat polymerization, material jetting, powder-bed fusion, and others — but VAT photopolymerization dominates in practice. Specifically, Stereolithography (SLA) and Digital Light Processing (DLP) are the workhorses. They produce the smooth surface finish and tight tolerances dental restorations require, and they’re compatible with the biocompatible resins that have cleared regulatory review.

According to a bibliometric analysis covering 2013–2024 (indexed on PubMed, PMID 40354178), research activity in dental 3D printing peaked in 2023, with published output concentrated heavily on resin development and DLP/SLA advances.

Materials: Match the Substrate to the Application

Material selection is where many practices stumble. The clinical requirements for a temporary crown are completely different from those for a surgical guide or an implant-supported framework, and the regulatory picture varies accordingly.

Polymers — including acrylates, methacrylate resins, and photopolymer resins — are the most widely used materials. They’re appropriate for temporaries, diagnostic models, and denture bases. In August 2024, Formlabs Dental received FDA 510(k) clearance for its Premium Teeth Resin, a nanoceramic material, for crowns, inlays, onlays, veneers, and up to seven-unit temporary bridges — per the manufacturer’s own regulatory filing. Separately, new biocompatible materials incorporating Remora anti-biofilm technology received both FDA and Health Canada approval in 2025, targeting splints and devices prone to biofilm accumulation.

Ceramics and metals are required for load-bearing permanent restorations. These typically involve powder-bed fusion or milling rather than desktop resin printing, and they generally remain in the lab rather than the practice.

One area still finding its footing: 4D printing, which uses shape-memory materials that change form after fabrication. It’s a concept with real long-term potential, but clinical validation is limited and it’s not a near-term workflow consideration for most practices.

Adoption Rates and the Case for In-House Printing

The gap between lab and practice adoption is notable. An ADA Clinical Evaluators Panel survey — the full details of which were not available for independent verification at time of publication; readers should consult the ADA directly for the primary data — reportedly found that a substantial majority of U.S. dental labs had incorporated 3D printing as of 2023, while a much smaller share of dentist respondents used a printer in-practice. Among those who do print chairside, improved efficiency and reduced cost were cited as primary benefits, and motivations for adopting included complementing existing digital technologies and gaining workflow control, per that survey.

That workflow-control argument is real. Printing in-house eliminates lab turnaround time, reduces shipping costs, and lets the practice respond to same-day needs — a model fitting well into the broader shift toward digital dentistry at the practice level. The limiting factor, particularly for independent practices and smaller labs, is upfront cost. Equipment, validated resins, post-processing hardware, and the training required to use all of it reliably add up quickly, and the global dental 3D printing market — valued at $3.96 billion in 2025 and projected to reach $10.06 billion by 2030 at a 20.5% CAGR, per industry reporting cited by Dentistry Today (figures originating from third-party market research, not independently verified) — is still priced accordingly.

Where to Start

For practices considering their first printer, surgical guide production is the most defensible entry point: the clinical case is strong, the volume at most implant-active practices can support the equipment cost, and the workflow integrates naturally with existing cone beam and planning software. Model printing for aligner cases is a close second, especially for practices already using a digital scanner. (If you’re still evaluating scanners, the best intraoral scanner guide is a useful prior step.)

Jumping straight to in-house crown and bridge production requires more investment — in validated materials, calibrated equipment, and staff training — and the regulatory requirements are stricter. For most independent practices, that’s a second phase, not a starting point.
