THE 7 STEP PROVE IT PROCESS

Talk Is Cheap.
Every Product Has to PROVE IT.

All products tested must prove itself through the same 7 step real world evaluation process.
Only then can it earn an official Ortho Outlaw rating.

Purchase Research

Identify a production problem, review the manufacturer's claims and decide if the product is worth a shot in an ortho lab.

Receive and Install

Document unboxing, installation, setup requirements, learning curve and everything needed to get up and running.

Operate in Production

Put the product to work on real cases inside an active orthodontic lab to evaluate everyday performance, reliability and workflow impact.

Verify Performance

Study production, reliability, maintenance, customer support, ROI value and overall consistency during everyday lab production.

Evaluate Results

Calculate performance, workflow impact, limitations and available alternatives against the manufacturer's claims and real world expectations.

Invest or Ignore

Decide whether the product has proven itself, earns a place in an ortho lab or practice and if it's worth the investment.

The Verdict

Tally the scorecard, explain the trade offs and deliver the final recommendation.

THE STANDARD

Approval Isn't Given. It's Earned.

Is there a product or piece of equipment the orthodontic community has been talking about? Let us know. We may feature it in an upcoming review.

Have a product or equipment you want us to test? Prove It!

01 How much does it cost?

At the time of this review, the MB1B7 bender was approximately $65,000 and included the first year of software and one roll of wire.

The annual software fee was approximately $8,900, and a replacement roll of wire was approximately $900.

Important: Pricing can change. Confirm the current purchase price, software fees and included equipment directly with AOS before ordering.
02 How accurate is it?

The short answer is that it is very accurate. Based on our experience, I would estimate around 90% on average, depending on the design and appliance.

The machine has struggled more with Adams clasps than with many of the other bends we produce. AOS has said it is actively working to improve that capability.

Bottom line: The machine produces bends that are consistent with the design shown on the screen, but final adjustments may still be needed.
03 Does it replace a wire bender?

No. You will still need a skilled wire technician and pliers for final adjustments, complex designs and bends the machine does not currently support.

Bottom line: The AOS complements an experienced technician. It does not replace one.
04 How many appliances can it produce per day?

There is not one universal answer because production depends on the appliance, the operator's experience and whether the operator is creating a new design or running a previously saved design.

In our laboratory, we design and bend throughout the day, so production varies with the workload. Once a design has been saved, the AOS can bend many wire forms in approximately 30 to 40 seconds. AOS reports that previously designed parts can reach approximately 100 to 110 wire forms per hour under peak batch production conditions.

My advice is not to focus only on the number of parts it can produce in a day. Look at how much it increases your laboratory's overall production. For the appliances our AOS supports, we experienced approximately an 80% increase in wire production while also improving consistency and reducing manual wire bending.

My advice: Measure the machine by the production problem it solves, not by a single maximum output number.
05 How long does training take?

Training is one of my favorite things about this machine. Someone with basic computer skills can usually learn the software and begin producing quality wire bends in approximately four to five days.

We have found that people who are comfortable with computers, CAD software or video games may understand the software and begin producing good bends in as little as one to three days. Learning orthodontic terminology and appliance design usually takes several additional weeks.

Bottom line: Training someone to operate the AOS is significantly easier than training someone to become an experienced hand wire bender. Strong computer skills can be a major advantage.
06 Can it bend straight wire?

No. The AOS uses spool wire rather than individual straight wire lengths. Multiple wire sizes are available.

07 How much maintenance is required?

The AOS requires very little routine maintenance. The main responsibilities are keeping the machine properly calibrated and maintaining the air compressor according to the compressor manufacturer's recommendations.

Regular calibration, which takes approximately 20 minutes, helps maintain accurate and consistent bends. Basic air compressor maintenance may include draining moisture, checking filters and monitoring air pressure.

Bottom line: Maintenance is minimal compared with the amount of production the machine can handle.
08 How often are software updates released?

The software is updated regularly with improvements, new features, bug fixes and performance enhancements. One thing I have appreciated is that the AOS team has been open to customer feedback.

When users identify ways to improve the workflow or make the software more efficient, the team is willing to listen and may incorporate those ideas into future updates. From my experience, AOS continues improving the software rather than leaving it unchanged after the sale.

09 How long does it take to see a return on investment?

Return on investment will be different for every orthodontic laboratory. It depends on production volume, labor costs, appliance mix, staffing challenges and how much hand wire bending you currently perform.

For the appliances the AOS can bend in our laboratory, we experienced approximately an 80% increase in wire production. That efficiency allowed us to produce more consistent wire bends while reducing the amount of manual wire bending required.

Look beyond the purchase price. Consider easier training for new employees, increased production, improved consistency, reduced dependence on experienced wire benders and the ability to better prepare your laboratory for growth or an eventual sale.

Bottom line: ROI is measured in more than dollars. It can also be measured in time saved, production capacity, consistency and the ability to scale more efficiently.
10 Can I finance the machine?

Financing may be available for qualified buyers. Low or no money down options may be available through Orthodontic Lab Solutions, depending on approval and current lending programs.

Is It Right for Your Lab?

Ask the Right Questions. Get the Right Results

Decision Guide

An automated wire bender can be a valuable production tool, but the right decision depends on your workload, staffing, budget and long term goals.

A Strong Fit

Who Should Consider Buying It

An automated wire bender can be a strong investment for laboratories that want to increase production, improve consistency, simplify training and prepare for future growth.

Growing orthodontic laboratories.
Labs struggling to hire experienced wire benders.
Labs with repetitive wire bending workflows.
Labs looking to increase production without adding the same number of technicians.
Labs wanting more consistent and repeatable bends.
Owners planning for long term growth, automation or an eventual transition.

May Not Be the Right Time

Who Should Not Consider Buying It

An automated wire bender is a production tool, not a complete replacement for experienced technicians. It may be difficult to justify when production volume is low or when most appliances fall outside the machine's current capabilities.

Labs producing only a small number of wire appliances each week.
Start up labs with limited budgets and low production.
Labs that primarily fabricate appliances the machine cannot currently bend.
Labs expecting the machine to completely replace skilled wire technicians.
Owners who are not ready to invest time in training and digital workflow implementation.
Labs without enough repetitive wire work to keep the machine productive.

Final Thoughts

Everything above explains how I reached this conclusion. Everything below is the advice I would give another laboratory before making this investment.

The AOS has been a great investment for our laboratory, but that does not automatically mean it is the right investment for yours. Every laboratory is different. Production volume, staffing, workflow, budget and long term goals all play an important role in determining whether an automated wire bender makes sense.

Technology

Automation Is Becoming Part of the Modern Laboratory

No matter which manufacturer you choose, automated wire bending technology has proven that many repetitive bends can be produced more consistently and taught more easily through software than through traditional hand bending alone.

It does not eliminate the need for experienced technicians, but it can reduce physical hand bending, support production growth and make training more approachable for a new generation of employees.

04

Long Term Value

A More Transferable Business

Technology and automation are becoming increasingly important for laboratories that want to remain current and competitive. The goal is not to automate everything simply because the technology exists. The goal is to choose tools that reduce dependency on a small number of highly experienced technicians, make workflows easier to teach and help create a stronger and more transferable business when the time comes to sell or retire.

05

Our Recommendation

Compare the Options Before You Decide

The AOS has served our laboratory well and has helped us adjust staffing around production instead of relying entirely on traditional wire bending experience. I would still encourage every laboratory to compare the other systems now available and consider which machine best fits its workflow.

If you are considering an automated wire bender and are unsure which system fits your laboratory, I am always happy to share what I have learned.

Automation should not replace the experience inside your laboratory. It should help that experience go further.

Independent Editorial Standards

Built by an Orthodontic Laboratory Owner. Not a Marketing Company.

For nearly 30 years, I've owned and operated orthodontic labs in Northern California. During that time I've built multiple ortho labs, redesigned workflows and implemented new technology to help our lab become more efficient and consistent. We were also proud to become the first fully digital orthodontic lab in Northern California. Along the way I've made some great investments and some costly mistakes, but every lesson has come from working in a real production environment where quality, consistency and efficiency matter every single day.

I created the Equipment Resource Center because I couldn't find the kind of honest, practical information I was looking for before making major purchasing decisions. Most of what I found came from marketing departments or sales people, instead of labs who actually depend on these products and equipment every day. The resources I was looking for simply didn't exist. My goal is to provide the kind of guidance I wish I had years ago, built on real laboratory testing, long term use and hands on experience.

Everything you'll find here is evaluated from the perspective of an ortho lab owner, not a salesperson. Every review, scorecard and recommendation is based on real world performance, not manufacturer claims, paid rankings or sponsored opinions. If a product earns my recommendation, it's because it proved itself in a working orthodontic lab and delivered real value where it matters most.

That same philosophy is the foundation of Orthodontic Lab Solutions. As an authorized reseller for carefully selected manufacturers and trusted industry partners, I only represent products and equipment I genuinely believe in and would confidently use in my own lab. My goal has never been to sell you equipment. My goal is to help you make informed decisions, avoid costly mistakes and invest in solutions that are right for your laboratory.

I don't represent products because I'm an authorized reseller. I'm an authorized reseller because I believe in the products I represent.

Whether you're researching your next piece of equipment, upgrading your workflow or building a new lab from the ground up, I hope this Equipment Resource Center gives you the knowledge, confidence and honest guidance to make informed decisions and invest in solutions that are right for your labs needs. And if you ever need help planning a new lab, redesigning your workflow, selecting equipment/products or navigating the buying process, I'm always happy to help.

If I wouldn't buy it for my own lab, I won't recommend it for yours.
