These applications transform traditional workflows while enhancing patient outcomes and practice efficiency through streamlined digital processes.
Dental Models for Case Visualization and Patient Education
Precision becomes paramount when you’re visualizing complex dental anatomy for case planning and patient communication. SLA 3D printed dental models transform digital scans into accurate physical representations of patient-specific anatomical structures.
SLA 3D printing bridges the gap between digital dental scans and tangible, patient-specific anatomical models for enhanced precision.
You’ll find these models enable detailed examination of tooth morphology, jaw alignment, and spatial relationships essential for diagnosis while reducing ambiguity compared to 2D imaging alone.
For patient education, you can use these tangible visual aids to explain dental conditions, procedures, and expected outcomes effectively. They improve patient comprehension by transforming abstract digital data into concrete physical examples.
You’ll discover that patient-specific models help illustrate treatment necessity, benefits, and limitations clearly, empowering shared decision-making and increasing patient satisfaction and treatment acceptance. These models also serve as valuable resources for dental training, providing students with hands-on experience examining diverse anatomical variations and pathological conditions.
Temporary Crowns and Bridges for Trial Restorations
When you need immediate provisional restorations, SLA 3D printing delivers temporary crowns and bridges that combine rapid production with clinical-grade performance. You can create same-day restorations using biocompatible, tooth-colored resins with nano-ceramic fillers that provide strength for up to 12 months. The digital workflow transforms your intraoral scans into precise temporary restorations through photopolymerization technology.
| Traditional Method | SLA 3D Printing |
|---|---|
| Days to weeks turnaround | Same-day delivery |
