What software is used for 3D dental modeling?

Okay, so I’m a dentist and I’m looking to upgrade my practice’s technology. I’ve been hearing a lot about 3D dental modeling and how it can improve things like implant planning, creating crowns and bridges, and even designing clear aligners. It sounds like it can really streamline workflows and improve patient outcomes.

But I’m completely lost on what software is actually used for this stuff. There seem to be so many options, and they all have different features and price points.

Specifically, I’m interested in software that can:

• Import data from intraoral scanners – We’re planning to invest in an intraoral scanner, so compatibility is key. Ideally, it should be able to handle various file formats (STL, PLY, etc.) easily.
• Allow for virtual articulation – Being able to simulate jaw movements is crucial for treatment planning.
• Design crowns, bridges, and implants – Obviously! The software needs to be capable of precise and accurate design.
• Generate surgical guides – Being able to create surgical guides for implant placement would be a huge plus.
• Integrate with CAD/CAM systems – I’d like something that can seamlessly integrate with our existing CAD/CAM milling machine.

Bonus points if the software is relatively user-friendly, has good customer support, and offers some kind of training. I’m willing to invest in learning something new, but I don’t want it to have an incredibly steep learning curve.

Are there any specific software packages that people would recommend for these applications? Are there major differences in accuracy and workflow between the big players in the market? What about pricing models? Are we talking about subscription-based licenses or one-time purchases?

Any insights would be greatly appreciated!

Answer

A wide variety of software solutions are used for 3D dental modeling, catering to different needs and specializations within the field.

The CEREC software focuses on ease of use and speed, making it suitable for in-office milling. It offers guided workflows and pre-defined parameters for various restoration types.
• Planmeca PlanCAD Easy: This CAD/CAM software is part of the Planmeca Romexis suite and is used for designing restorations that can be milled using Planmeca’s milling units. It emphasizes ease of use and efficient workflows, focusing on single-visit dentistry. It is known for its user-friendly interface and tight integration with Planmeca’s other digital dentistry products.
• DWOS (Dental Wings Open Software): Dental Wings offers an open and versatile CAD/CAM platform. DWOS provides a range of modules for designing various dental restorations, including crowns, bridges, implant abutments, and dentures. It is designed to integrate with different scanners and manufacturing equipment.

Orthodontic Planning Software:

• 3Shape Ortho Analyzer: This software allows orthodontists to create digital study models from intraoral scans or impressions. It provides tools for analyzing tooth positions, measuring arch lengths, and planning orthodontic treatments. It is widely used for treatment planning with clear aligners, brackets and indirect bonding.
• OrthoCAD (Align Technology): This software is specifically designed for planning Invisalign treatments. It allows orthodontists to visualize tooth movements, create ClinCheck treatment plans, and monitor treatment progress.
• SureSmile (OraMetrix): SureSmile software is used for designing custom archwires and planning orthodontic treatments. It allows orthodontists to visualize tooth roots and plan precise tooth movements.
• Exocad ChairsideCAD with Ortho Add-on: Exocad’s ChairsideCAD with the Ortho add-on provides features for designing orthodontic appliances, such as aligners and indirect bonding trays.

Implant Planning Software:

• NobelClinician (Nobel Biocare): NobelClinician software allows for the virtual placement of dental implants based on CBCT scans. It provides tools for assessing bone density, planning implant positions, and designing surgical guides. It facilitates collaboration between surgeons and restorative dentists.
• SimPlant (Materialise): SimPlant is a comprehensive implant planning software that allows for the virtual placement of implants based on CBCT scans. It provides tools for nerve canal identification, bone density assessment, and surgical guide design.
• Blue Sky Plan (Blue Sky Bio): This is a free and open-source implant planning software that offers a wide range of features, including implant placement planning, surgical guide design, and prosthetic design. Its open-source nature makes it a popular choice for users looking for a cost-effective solution.
• 3Shape Implant Studio: Integrates seamlessly with 3Shape Dental System, allowing for comprehensive implant planning and surgical guide design.

General 3D Modeling Software (Adapted for Dental Use):

• Blender: A free and open-source 3D creation suite, Blender is sometimes used for dental modeling, particularly for visualizing complex anatomical structures or creating custom dental appliances. Its versatility and customizability make it a viable option for users with advanced 3D modeling skills.
• Meshmixer (Autodesk): Meshmixer is a free software tool for manipulating and editing 3D meshes. It can be used for tasks such as cleaning up scanned data, smoothing surfaces, and creating custom dental models.

Factors Influencing Software Choice:

The selection of the appropriate software depends on several factors, including:

• Specific application: Restorative dentistry, orthodontics, implantology, etc.
• Workflow integration: Compatibility with existing scanners, milling machines, and 3D printers.
• User expertise: The level of experience with 3D modeling software.
• Cost: Software prices vary widely, from free open-source options to expensive commercial suites.
