Chairside Milling vs. 3D Printing: How I Help Doctors Decide

Building the Right Same-Day Dentistry Workflow for Your Practice

One of the most common questions I get from doctors exploring same-day dentistry is:

“Should I start with milling or 3D printing?”

The reality is, there’s no universal answer.

It really depends on:

• what type of dentistry you’re doing
• what workflows you want to improve
• what problems you’re trying to solve
• and where you ultimately want your practice to go long-term

What I’ve noticed over the last few years is that doctors often come into this conversation thinking they need to choose one technology instead of the other. In reality, milling and printing solve different problems inside the practice, and for many offices, they eventually end up implementing both.

I talked more broadly about this shift toward same-day workflows in my article on modern same-day dentistry and why more practices are bringing restorative manufacturing in-house. This article is more specifically about helping doctors understand where milling and printing each fit into that conversation.

The Wrong Way to Approach the Decision

One mistake I see pretty often is doctors evaluating these technologies strictly based on:

• specs
• speed
• material cost
• or which machine looks more impressive

That’s usually the wrong place to start.

The better question is:

“What type of workflow am I trying to build?”

Because same-day dentistry is really about workflow efficiency, patient experience, control, and flexibility — not just owning a piece of equipment.

If a doctor tells me:

• “I want stronger long-term restorations”
• “I want to do more zirconia”
• “I want to replace more lab crown workflows”

then we’re probably leaning toward milling.

If another doctor says:

• “I want to start bringing more things in-house”
• “I want lower-cost workflows”
• “I want to produce provisionals, guides, splints, or emergency cases”

then printing may make more sense as a starting point.

Where Chairside Milling Really Shines

When I talk to doctors about milling, the biggest advantages usually come down to:

• strength
• long-term durability
• esthetics
• and restorative control

Modern chairside mills have come a long way from where CAD/CAM systems were years ago. A lot of doctors still assume milling workflows are complicated, slow, or difficult to implement, but today’s systems are dramatically more streamlined.

One of the things I like most about the Perfit Ovis Milling Machine workflow is how open and flexible it is. Doctors can integrate:

• different scanners
• different design software
• AI-assisted workflows
• cloud design services
• and multiple restorative materials

without getting locked into a closed ecosystem.

That flexibility matters because every practice works differently.

Fully Sintered Zirconia Changed the Conversation

Honestly, one of the biggest changes in chairside dentistry over the last several years has been fully sintered zirconia.

For a long time, one of the major objections to same-day milling was:

“I don’t want to deal with oven time.”

That was fair.

Traditional zirconia workflows could create longer appointments and additional workflow steps that some doctors simply didn’t want to manage chairside.

But newer fully sintered zirconia materials have simplified things dramatically. Being able to polish and deliver restorations without long sintering cycles changes the practicality of same-day zirconia workflows quite a bit.

That’s usually the point where a lot of doctors start realizing:

“Okay…this is much more realistic than I thought.”

Where 3D Printing Really Excels

On the printing side, what excites a lot of doctors is the versatility.

Printing allows practices to produce a wide variety of applications quickly and efficiently, including:

• provisionals
• splints
• surgical guides
• temporary restorations
• models
• onlays
• veneers
• emergency cases

And for many practices, printing represents a very approachable way to begin bringing manufacturing in-house.

The SprintRay Midas workflow has been especially interesting because it’s helped expand what doctors think is possible chairside. A lot of offices initially think about printing strictly for models or surgical guides, then quickly realize how many restorative and same-day applications are becoming viable.

Another thing doctors like about printing is the lower material cost and the ability to offer additional treatment options to patients.

Sometimes a printed solution becomes a really good:

• transitional restoration
• lower-cost option
• emergency solution
• or same-day convenience workflow

And patients absolutely value that flexibility.

A Lot of Doctors Eventually Want Both

One thing I’ve learned after having this conversation with a lot of practices is that milling and printing usually stop feeling like competitors once doctors understand the workflows better.

They start realizing:

• milling solves certain problems extremely well
• printing solves different problems extremely well

and together they create a much more complete digital workflow.

Typically:

• milling becomes the long-term restorative solution
• printing becomes the speed and versatility solution

That’s why I rarely frame this conversation as:

“Which technology is better?”

Instead, I usually ask:

“What do you want your workflow to look like a few years from now?”

That tends to lead to a much more productive conversation.

The Biggest Fear Usually Isn’t Technology

Interestingly, most doctors are not actually afraid of the machine itself.

The biggest fear is usually:

“Can I realistically implement this in my practice?”

That’s the real concern.

Scheduling.
Team adoption.
Learning curve.
Patient flow.
Time.

Those are the things doctors worry about most.

And honestly, once we walk through the workflow together, most of those concerns become much more manageable than they initially expected.

I’ll talk more about that in my upcoming article specifically on scheduling and why same-day dentistry often creates more efficiency than doctors expect.

My Advice to Doctors Exploring Same-Day Dentistry

If you’re exploring milling or printing, my biggest advice is:
don’t start with the machine.

Start with:

• your workflow goals
• your patient experience goals
• your clinical priorities
• and the type of dentistry you want to grow

Technology works best when it supports the workflow you’re trying to create — not the other way around.

Some practices start with printing.
Some start with milling.
Some implement both at the same time.

There’s no single correct path.

The goal is building a workflow that:

• improves efficiency
• gives you more control
• creates better patient experiences
• and makes dentistry easier and more predictable for your team long-term

Because at the end of the day, same-day dentistry really isn’t about technology.

It’s about creating a better practice experience for both the doctor and the patient.
