What Is Digital Dentistry and What Does a Complete Digital Workflow Entail?
In a clinical setting, digital dentistry is the integration of diagnosis, planning, and fabrication around a virtual patient (a 3D model that includes bone, teeth, and soft tissues). The goal is to reduce clinical uncertainty and procedural variability through data-driven decisions and devices manufactured with controlled tolerances.
Summary of the workflow (end-to-end):
- Acquisition: CBCT (bone volume and critical structures) + intraoral scanner (dental/gingival surface).
- Registration/Fusion: DICOM ↔ STL/PLY/OBJ alignment to obtain a single, reliable model.
- 3D Planning: Simulation of movements, implant positions, surgical paths, and mockups.
- CAD/CAM manufacturing: guides, splints, temporaries, and restorations based on the validated plan.
- Execution and monitoring: clinical application and updating of the virtual patient with a verification scan.
Operational advantages: lower retreatment rate, faster multidisciplinary decision-making, and more efficient chairside appointments thanks to pre-planned guides and temporary restorations.
Key technologies: CBCT, intraoral scanner, and CAD/CAM
- CBCT (3D X-ray): anatomical map to assess bone thickness/volume, nerve pathways, and relationship to sinuses.
- Intraoral scanner (IOS): precise capture of dental morphology and margins; basis for occlusion and soft tissues.
- CAD/CAM: Transfers the treatment plan to the clinical device (surgical guides, splints, veneers, and prostheses) with control over libraries and tolerances.
In implantology, this process relies on the workflow described in digital implantology software to define the system, position, axis, and type of guide with prosthetic consistency.
In orthodontics, digital orthodontic software manages setup, sequencing, and anchorage (aligners or brackets), maintaining traceability between diagnosis, treatment plan, and fabrication.
DICOM and STL/PLY/OBJ files: how they fit into the workflow
- DICOM: volumetric data from the CBCT (bone, roots, anatomical pathways).
- STL/PLY/OBJ: surface meshes (teeth/gums), with the option to add texture and color.
Recommended fusion protocol:
- Artifact removal from CBCT images.
- Export IOS as STL (and PLY/OBJ if color is required).
- Registration using stable points/surfaces (palate, smooth surfaces, occlusal surfaces).
- Validation in axial/sagittal/coronal sections.
- Lock the registration to ensure that the entire team works from the same reference.
Why it matters: Millimeter-level crown–root correlation determines the precision of implant placement, guided surgery, and orthodontic planning.
Clinical Applications of the Digital Workflow in Orthodontics, Implantology, and Aesthetics
Orthodontics (aligners or braces)
- Digital setup with space and collision checks.
- TAD planning with validated bone support.
- Selection of aligners vs. braces based on anchorage, complexity, and treatment time.
- Plan traceability and consistency with planned restorations.
Implantology (implant placement)
- Prosthetically guided positioning based on the ideal emergence path.
- Measurement of distances to critical structures and assessment of bone density.
- Use of prosthetic libraries to avoid incompatibilities in guides and abutments.
- Planned temporary restorations/immediate loading with occlusion and soft tissue considerations.
Guided Surgery
- Definition of instrument paths using sleeves and drills within known tolerances.
- Digital verification of stability and supports (bone/tooth/mucosa).
- Traceability from planning → fabrication → execution without manual reinterpretation.
Aesthetics and Rehabilitation
- Functional mockups (aesthetics, phonetics, and occlusion) aligned with the restorative plan.
- Preparation guides to transfer the design to the dental chair with control over reduction and margins.
- Clinic-lab communication based on the same 3D model.
Multidisciplinary 3D planning and “virtual patient”
The team (surgery, orthodontics, prosthodontics, periodontics) works on a single, versioned 3D model. In brief meetings, positions, spaces, and aesthetic-functional criteria are reviewed; feedback is addressed; and a final version is released to guide fabrication.
Digital trial prior to printing: validate occlusion, guide fit/stability, and prosthetic space in 3D. If correct in the model, the clinical procedure is more predictable.
Operational impact: fewer misunderstandings between the clinic and the lab, fewer reworks, and more efficient appointments.
Clinic and Lab: How to Coordinate the Digital Workflow Without Errors
- Roles: clinical coordinator and technical liaison in the lab.
- Nomenclature: Patient_LastName_Date_Stage and versioning (v1-plan, v2-revision, v-final).
- Synchronized libraries: same version of connections/components on both sides.
In implantology, the package (CBCT, IOS, plan, libraries) must exactly match the version generated in the digital implantology software to avoid misalignments with connections or sleeves.
Interoperability and Quality Control Checklist
- Before planning
- Recent CBCT with appropriate FOV and parameters.
- Complete, clear, and up-to-date intraoral scan.
- Files
- DICOM + STL/PLY files from the same patient and date.
- Updated and documented libraries/attachments (brand, connection).
- Data merging
- Validated fusion across 3 sections, record deviations, and lock the final reference.
- Plan
- Implants with safe distances and defined prosthetic corridors.
- Orthodontics with verified spaces and sequences.
- Manufacturing
- Digitally verified guides/splints (tolerances and stability) before printing.
- In the clinic
- Guide trial (stability/fit) and occlusal verification.
- After
- Follow-up scan and update of the virtual patient.
Getting Started in a Digital Dental Clinic: Investment, Training, and ROI
Startup requirements
- Reliable intraoral scanner.
- Software tailored to specific cases (implantology, orthodontics, cosmetic dentistry).
- 3D printer for splints, guides, and temporary restorations.
- Operational training focused on the clinic’s main workflow.
Training Plan: To begin clinical digitization, it is advisable to start with repeatable protocols (e.g., splints and pilot guides) that allow for standardized times and quality controls. Once 10–15 cases with consistent results have been completed, it is reasonable to scale up to immediate loading and full restorations, incorporating additional variables without compromising predictability. At the same time, it is essential to standardize templates and presets by case type (nomenclature, libraries, printing and verification parameters) to reduce variability among operators and accelerate the team’s learning curve.
Expected return: The adoption of 3D planning typically results in increased acceptance of treatment plans thanks to clearer clinical communication, as well as a reduction in chair time and the number of appointments due to guided fabrication and fewer rework procedures. In the medium term, the practice can incorporate new services (aligners, guided surgery, functional mockups) that diversify its offerings and improve the margin per procedure. With moderate volume and rigorous tracking of key metrics (acceptance rates, turnaround times, rework, and margin per service), the digital ecosystem often pays for itself within 9–18 months.
