Medit i700 vs Aident AI-30: An Unbiased Feature, Performance and Clinical Workflow Analysis (2026)

The intraoral scanner (IOS) market in 2026 presents dental professionals with an increasingly complex choice. What was once a decision between "going digital or staying analog" has evolved into a more nuanced question: which digital path is right for your practice?

Two scanners representing fundamentally different approaches to digital dentistry have emerged as compelling options: the Medit i700-a South Korean industry workhorse with a proven track record-and the Aident AI-30-a Chinese-engineered challenger built around clinical ergonomics and open-system flexibility.

This analysis compares these two devices across technical specifications, clinical performance data, software ecosystems, and practical workflow considerations. The goal is not to declare a winner, but to provide dental professionals with the objective information needed to determine which scanner best aligns with their practice's specific needs, patient mix, and long-term digital strategy.

Part One: Product Overview & Brand Positioning

Medit i700 – Speed & Ecosystem Leader

Medit, founded in 2000 in Seoul, South Korea, built its reputation in industrial 3D metrology before entering dentistry. The i700 (introduced in 2021) is the company's flagship wired scanner, with a wireless version released later. It has twice won the Cellerant "Best of Class" award and is backed by extensive clinical research. The i700 is positioned as a premium solution for clinics and labs that prioritise scanning speed, a mature cloud ecosystem (Medit Link), and a proven track record.

Typical users include high‑volume practices, labs that process dozens of cases daily, clinics already invested in the Medit ecosystem, and users who want both wired and wireless options.

Aident AI‑30 – Open, Lightweight & Value‑Driven

Aident Technology Co., Ltd., established in Shenzhen, China, in July 2023, represents a new generation of dental technology manufacturers. Despite its recent founding, the R&D team brings over 15 years of optical scanning experience, with 7 years of frontline dental market insight. The AI‑30 is the result of 100% in‑house hardware and software development.

The AI‑30 has gained visibility at major international exhibitions (AEEDC Dubai, Sino‑Dental Beijing, IDS Germany, VIDEC Vietnam). Its positioning emphasises clinical practicality, ergonomic comfort, open‑system freedom, and predictable total cost of ownership - making it especially attractive for small‑to‑medium practices, orthodontic clinics, and first‑time digital adopters.

What the Numbers Actually Mean

Accuracy – Both devices claim <10 μm full‑arch accuracy. Medit's numbers are backed by multiple peer‑reviewed studies; Aident's specifications meet the same clinical thresholds. For single crowns and short‑span bridges, the difference is negligible. For full‑arch implants, operator scanning protocol and consistency matter more than the last few micrometres.

Depth of field – The AI‑30's 20–25 mm range is a real differentiator. It allows more forgiving positioning, especially on deep margins and posterior regions, reducing the need for repeat scans. The i700's ~17 mm is industry standard but demands more precise tip handling.

Weight – 156 g vs 245 g (wired) or 328 g (wireless). Over a full day of scanning, that difference accumulates. For clinicians who do multiple full‑arch scans daily, the lighter handpiece directly reduces fatigue.

Part Three: Software Ecosystem & Open‑System Freedom

Both scanners are fully open systems, exporting STL, PLY, and OBJ files. This means you can work with any CAD software (exocad, 3Shape, etc.) and any laboratory that accepts open formats. However, the ecosystems differ in important ways.

Medit i700 runs on Medit Scan for Clinics, integrated with Medit Link - a cloud platform for case management, collaboration, and lab integration. The software is mature and feature‑rich, but the licensing and update model may involve ongoing costs. Users should verify current terms.

Aident AI‑30 uses AIDENT Scan for Clinics, featuring AI‑assisted scanning, auto‑completion, and 5 GB of free cloud storage. The standout advantage is lifetime free software updates – no subscription fees, no annual renewals. For practices that prefer to own their tools, this offers peace of mind and predictable long‑term budgeting.

Both platforms are compatible with exocad, 3Shape, and other major design software. The choice often comes down to whether you value the mature Medit Link ecosystem or prefer the simplicity and no‑subscription model of Aident.

Part Four: Clinical Scenario Suitability

1. Single Crown / Short‑Span Bridge

Both scanners deliver excellent results. The Medit i700's 70 FPS speed makes the scanning process feel fluid; the AI‑30's 20–25 mm depth of field offers more forgiveness on deep margins, which is particularly helpful for less experienced operators.

2. Full‑Arch Implant / Complex Restorations

Medit i700 has strong clinical evidence for full‑arch accuracy. The AI‑30's ≤10 μm accuracy and ultra‑deep depth of field are equally capable when used with proper scanning protocols. The AI‑30's lightweight design (156 g) reduces fatigue during lengthy full‑arch sessions.

3. Orthodontics (Clear Aligners / Retainers)

Medit's ecosystem offers established orthodontic workflows. The AI‑30's ultra‑light weight and deep depth of field are highly advantageous for orthodontic practices that scan each patient multiple times (pre‑treatment, progress, post‑treatment). Both export open STL/PLY/OBJ files for seamless integration with aligner planning software.

4. Chairside Same‑Day Restorations

Both scanners are fully open and integrate with exocad, 3Shape, and chairside 3D printers/milling units. The AI‑30's depth of field and low weight are particularly helpful in fast‑paced chairside environments, reducing repositioning time and operator fatigue.

Five Questions Worth Asking Before You Decide

What cases do we perform most often?
What file formats do our labs actually need?
Will the software require ongoing fees?
How quickly can the team learn to use it comfortably?
Can we take our data somewhere else later if needed?

These five questions usually reveal more than any "Top 10" ranking.

Conclusion

The Medit i700 and Aident AI‑30 are both excellent scanners, but they serve different priorities.

Medit i700 is the established workhorse – backed by research, driven by speed, and integrated into a mature ecosystem. It's ideal for high‑volume practices that value brand recognition, ecosystem depth, and proven performance.

Aident AI‑30 is a thoughtful, practical alternative – ultra‑light, ultra‑forgiving, fully open, and free from subscription fees. It's particularly well‑suited for practices where operator comfort, clinical forgiveness, and long‑term value are top priorities.

There is no "best" scanner for every clinic. The right choice depends on your case mix, team preferences, and digital roadmap. Both devices, when integrated into a careful workflow, can elevate patient care, improve efficiency, and reduce reliance on traditional impressions.

The best scanner is the one your clinicians still want to use every day two years later, that your labs can work with easily, and that does not restrict your future options.
