Evidence-Based Orthodontics: How to Apply It to Daily Practice
Actualizado: 26 ago
When making diagnosis and treatment planning decisions for our patients, one question should remain at the center of our clinical reasoning:
Why?
Why are we choosing this appliance?Why are we recommending this particular treatment approach?Why do we believe this is the most appropriate option for this patient?
These questions are fundamental to evidence-based orthodontics—an approach to clinical decision-making that combines the best available scientific evidence with clinical expertise and the individual needs of each patient.
What Is Evidence-Based Orthodontics?
Evidence-based orthodontics is not simply about reading scientific papers or choosing treatments that have been studied in clinical research.
It is about integrating three essential components:
The best available scientific evidence
The clinician's knowledge and experience
The individual patient's needs, characteristics, and preferences
This framework helps orthodontists make treatment decisions based on more than habit, personal preference, or what happens to be popular at a particular moment.
The goal is not to eliminate clinical judgment. Quite the opposite, evidence gives us a stronger foundation for clinical judgment.
From “How?” to “Why?” in Orthodontic Treatment Planning
When we attend professional meetings, congresses, or continuing education events, we are constantly exposed to treatment approaches and clinical results presented by colleagues and industry experts.
Most of the time, these presentations demonstrate successful treatment outcomes.
But when we encounter a similar clinical situation in our own practice, we often discover that there is more than one possible way to approach the problem.
Our first instinct is often to ask:
“How should I treat this?”
Evidence-based orthodontics encourages us to take the next step and ask:
“Why should I treat it this way?”
The answer should not simply be based on what is popular, what a particular appliance is capable of doing, or what we have seen demonstrated successfully.
Instead, we should seek the best available evidence and determine how relevant that evidence is to the specific patient in front of us.
That is where evidence-based clinical decision-making becomes particularly valuable.
Evidence Before Trends in Orthodontics
Orthodontics is constantly evolving.
New appliances, clear aligner systems, digital workflows, artificial intelligence tools, and treatment protocols are introduced into the market at an impressive pace.
It is easy for clinical decision-making to be influenced by market trends, the level of penetration of a particular company in our region, or the opinions of influential speakers.
These factors can certainly help us discover new technologies and treatment possibilities. However, they should not be the primary source of evidence behind our clinical decisions.
Orthodontic companies are important partners in our daily practice. They develop technologies and tools that can expand our treatment options and improve our workflows.
However: Technology should support our clinical decision-making—not determine it.
Our treatment decisions should ultimately be grounded in our clinical knowledge and experience, the available scientific evidence, and the individual needs of our patients.
A Practical Example: “How Much Can I Expand?”
Consider one of the questions we frequently encounter in orthodontics:
“How much can I expand?”
It is tempting to answer this question by looking at what a particular appliance or treatment system is technically capable of achieving. But that is not necessarily the right clinical question. A better question is:
“How much expansion is appropriate and predictable for this particular patient?”
To answer that question, we need to consider the patient's diagnosis, skeletal and dental characteristics, age, growth status, periodontal conditions, initial tooth inclination, treatment objectives, and other relevant clinical factors.
We then need to look at the available evidence involving patients with comparable characteristics and evaluate what the literature tells us about the expected effects, limitations, stability, and potential risks of the proposed approach.
The question therefore changes from: “Can this appliance do it?” to:
“Is this the appropriate amount of correction for this patient, and what evidence supports it?”
That shift in thinking is at the heart of evidence-based orthodontic treatment planning.
Evidence-Based Orthodontics in the Digital Era
Historically, answering these questions required considerable time searching scientific databases such as PubMed, the Cochrane Library, and other sources of peer-reviewed literature.
Today, digital tools and artificial intelligence can make this process significantly more efficient.
AI-assisted research platforms can help clinicians identify relevant literature, summarize research findings, compare studies, and explore specific clinical questions.
However, there is an important distinction:
AI can help us find and process evidence. It should not replace our clinical judgment or our critical appraisal of that evidence.
This distinction becomes particularly important when using AI in orthodontics.
The quality of an AI-generated answer depends on the quality, relevance, and interpretation of the underlying evidence. Differences in diagnosis, patient characteristics, methodology, biomechanics, treatment objectives, and outcome assessment can significantly influence the conclusions of individual studies.
AI should therefore be viewed as a tool for supporting clinical reasoning—not replacing it.
How to Apply Evidence-Based Orthodontics in Daily Practice
Evidence-based orthodontics does not mean that every clinical decision requires an extensive literature review. Instead, it means developing a habit of asking better questions.
Before accepting a treatment approach, ask yourself:
Why am I choosing this approach?
What evidence supports it?
Does that evidence apply to this particular patient?
What are the limitations and potential risks?
How does my clinical experience influence this decision?
What does the patient actually need and value?
This approach allows us to move beyond simply following protocols and toward more individualized orthodontic treatment planning.
Digital Orthodontics Should Be More Than Moving Teeth on a Screen
Digital orthodontics has transformed the way we collect records, analyze information, visualize treatment outcomes, and communicate treatment plans.
But digital orthodontics should be about much more than moving teeth on a screen.
The real value of a digital workflow is its ability to help us analyze information, challenge assumptions, and make better clinical decisions.
This is also where diagnostic and evidence-based treatment planning can play an important role.
A treatment planning service should not simply provide a digital setup or execute the clinician's instructions.
It should help translate the patient's diagnosis and treatment objectives into a clinically sound digital plan—while giving the treating orthodontist the information and reasoning needed to make the final decision.
Ultimately, technology should make evidence-based orthodontics more accessible, more efficient, and more consistent—not replace the clinician behind the decision.
Because in orthodontics, perhaps the most important question is still the simplest one:
Why?
