ArchForm 2.6.4.1 (Clear Aligner Treatment & 3D Print Software)

Overview of ArchForm Orthodontic Software

ArchForm is a specialized orthodontic software platform that enables dental professionals to design, plan, and produce clear aligners directly in their practices. This advanced treatment planning software streamlines the entire aligner workflow—from intraoral scan import to final 3D printing—allowing orthodontists and general dentists to maintain greater clinical control while reducing lab costs by up to 84% .

Developed by ArchForm Inc., a Sunnyvale-based dental technology company, the software combines artificial intelligence with an intuitive interface to simplify complex orthodontic treatment planning . ArchForm’s approach has gained significant traction among practitioners seeking to move aligner production in-house, with more than 800,000 patient cases planned using the platform .

What sets ArchForm apart from traditional aligner services is its pay-per-case pricing model, which allows practices to start with a single case and scale usage as their in-house aligner production grows . This flexibility, combined with FDA 510(k) clearance as a medical device, positions ArchForm as a compliant and accessible solution for modern orthodontic practices .

Key Features of ArchForm Treatment Planning Software

Automated Segmentation and AI-Powered Design

ArchForm leverages machine learning for accurate tooth segmentation, automatically identifying the gingival border of each tooth within seconds . The software’s segmentation algorithm can be manually adjusted using an intuitive brush-editing feature, giving clinicians precise control when needed. Automated initial alignment further accelerates the treatment planning workflow, allowing practitioners to focus on clinical decision-making rather than repetitive setup tasks .

Comprehensive Staging and Movement Control

The software provides granular control over tooth movement sequencing:

• Multiple intermediate goals can be set to control movement sequence and apply overcorrection 

• Sequential distalization is planned automatically based on treatment objectives 

• The number of aligners adjusts dynamically based on planned tooth movements 

• Clinicians can set multiple intermediate goals to control the sequence of movements 

Attachment and Cutout Management

ArchForm offers complete attachment control, allowing clinicians to:

• Adjust attachment position, size, and gingival tilt 

• Add multiple attachments, including lingual attachments for root angulation and anchorage control 

• Fully adjust placement and sizing for hooks and elastics 

• Add aligner cutouts for hooks or elastics directly from the software interface 

Advanced Trim and Model Preparation

The software includes specialized tools for model refinement:

• A lasso trimming tool allows users to remove unwanted material, such as excess palate coverage, by drawing a circle to cut it out 

• Auto-orientation automatically aligns the midline and occlusal planes regardless of scan angle 

• Hollow model export saves up to 50% of resin costs 

Bite Management and Pontic Placement

For complex cases requiring bite management:

• Bite stops can be added automatically to anterior teeth or placed individually, maintaining a flat plane parallel to the occlusal plane 

• Bite shifts allow full adjustment of mandibular position to show desired end-of-treatment results 

• Pontics can be placed following extraction and will dynamically resize as spaces close 

3D Printing Integration

ArchForm streamlines the transition from digital planning to physical production:

• Auto-export settings prepare models for printing without manual intervention 

• Vertical printing support and auto-labeling are automatically applied 

• Direct Print Aligner (DPA) workflow supports validated 3D printers with integrated software, UV curing, and centrifuge systems

How to Use ArchForm: Complete Workflow Guide

Importing Scans

Begin by importing intraoral scan files (.stl format) into ArchForm using the software’s import function . The software will automatically orient the scan, aligning the midline and occlusal planes .

Model Preparation

Use the lasso trimming tool to remove excess material if needed . The software’s automated segmentation then identifies individual tooth borders, which can be refined using the brush-editing feature .

Treatment Planning

1. Set treatment objectives: Define the final position for each tooth by dragging them to target positions 

2. Adjust arch shape: Use control points to customize the arch form for each patient 

3. Configure attachments: Place and adjust attachments, including lingual options for root control 

4. Plan staging: Set intermediate goals and allow sequential distalization to be automatically calculated 

Advanced Feature Application

• Add bite stops for deep bite cases 

• Configure bite shifts to show desired mandibular positioning 

• Place pontics following extractions 

• Adjust IPR amounts with one-click controls 

Export for Production

Once planning is complete, use the auto-export function to prepare print-ready files . For in-house production, the software automatically adds printing supports, applies labels, and creates hollow models when needed .
