Service Overview

Orthodontic Aligner Software Development.

Orthodontic solutions development combines software engineering, domain expertise and data processing to improve clinical and operational workflows. In orthodontics, digital treatment planning depends heavily on accurate 3D dental models and reliable geometric computation.

We build specialized orthodontic solutions that enables dental professionals, laboratories and aligner manufacturers to process 3D dental models, analyze individual teeth, plan controlled tooth movements and prepare treatment stages for downstream manufacturing.

Our engineering capabilities span the complete digital workflow from scan import and mesh processing to tooth segmentation, landmark computation, treatment planning, tooth movement, staging, attachment management, collision analysis and manufacturing preparation.

Core Capabilities

Engineering the complete solution

Our engineering team covers the complete orthodontic digital workflow, from importing and preparing dental scans through treatment planning, tooth movement, staging and manufacturing-ready model generation.

Import Scan Models

Bring intraoral scans and 3D dental models into the digital workflow.

Model Preparation

Clean, repair, simplify and prepare unsegmented dental meshes.

Tooth Segmentation

Separate individual teeth and relevant anatomical structures from the scan.

Landmark Computation

Compute FACC, tooth axis, origin, cusp and other dental landmarks.

Roots & IPR

Attach root representations and manage interproximal reduction requirements.

Gingiva & Base

Generate gingival geometry and attach or construct required base structures.

Trimline

Generate controlled aligner trimlines based on the digital treatment geometry.

Virtual Filler

Generate virtual filler regions to support aligner and manufacturing workflows.

Tooth Alignment

Move and orient teeth toward planned target positions.

Occlusion & Spacing

Evaluate T2 occlusion, IPR spacing and tooth-to-tooth relationships.

Attachments

Place tooth attachments and analyze attachment-tooth relationships.

Collision Detection

Detect unwanted intersections and geometric conflicts.

Treatment Staging

Break planned movement into controlled sequential treatment stages.

Manufacturing

Prepare final geometries and manufacturing-specific digital outputs.

Export

Export treatment and production models in OBJ, STL and other required formats.
