Conventional Braces vs Self-Ligating Braces: Differences, Advantages and Disadvantages

Orthodontics is an essential field of dentistry that not only improves the aesthetics of the smile but also corrects bite (occlusion) problems that can compromise chewing, speech, and even the health of the temporomandibular joints (TMJ). Nowadays, patients have access to various orthodontic treatment options, with the most common being conventional braces and self-ligating braces.

Many patients come to their appointment with the question: “Which is better for me – conventional or self-ligating braces?” To give a clear answer, it is crucial to understand the differences between the two, as well as their advantages and disadvantages. Dr Cláudio Alferes, a specialist in corrective orthodontics and occlusion problems, takes the time to explain each option individually, ensuring that every patient chooses the most appropriate solution for their case.

What are orthodontic appliances?

Orthodontic appliances are devices used to align teeth, correct the bite (occlusion), and improve the aesthetics of the smile. They work by applying controlled forces to the teeth, gradually moving them into the correct position.

For Dr Cláudio Alferes, more than just an aesthetic matter, the purpose of orthodontic appliances is to restore functional balance between teeth, bones, and joints, reducing the risks of tooth wear, TMJ pain, or chewing problems.

What are conventional braces?

Conventional braces are the most traditional and well-known orthodontic system. They consist of metal or ceramic brackets, orthodontic wires, and elastic ligatures that connect the two, applying pressure to move the teeth.

Despite being used for decades, they remain highly effective and suitable for countless clinical cases.

Structure of conventional braces

Brackets are bonded to the surface of the teeth and linked together by an orthodontic wire. Small elastics (“rubber bands”) secure the wire to the bracket, ensuring the necessary force is applied.

Advantages of conventional braces

• Proven effectiveness: decades of use, a safe and predictable solution.

• Clinical versatility: suitable for nearly all types of malocclusion.

• Cost-effective: generally more affordable than newer systems.

Disadvantages of conventional braces

• More visible: even aesthetic versions, as elastics can stain over time.

• More frequent appointments: regular elastic replacements required.

• Higher friction: creates more resistance between wire and bracket, which can lengthen treatment time or cause some discomfort.

  
  

What are self-ligating braces?

Self-ligating braces are a technological evolution of the conventional system. The main difference is that they do not use elastic ligatures: the brackets have a small clip or mechanism that directly holds the orthodontic wire.

This seemingly simple detail impacts the patient’s experience, reducing friction and making appointments quicker.

Structure of self-ligating braces

Each bracket has a built-in locking system that secures the wire, eliminating the need for rubber bands. Available in both metal and more discreet ceramic versions.

Advantages of self-ligating braces

• Less friction: wire slides more easily, allowing potentially faster tooth movement.

• Greater comfort: less pressure felt by the patient.

• Fewer appointments: no elastic replacements required.

• Better oral hygiene: no ligatures means less plaque build-up.

Disadvantages of self-ligating braces

• Higher cost: generally more expensive than conventional braces.

• Not always necessary: in some cases, offers no significant advantage over conventional braces.

• Variable aesthetics: although discreet versions exist, metal brackets remain visible.

Conventional vs self-ligating braces – main differences

Although both aim to align teeth and correct occlusion, there are practical differences that influence the patient’s experience and, in some cases, treatment duration.

Aspect	Conventional Braces	Self-Ligating Braces
Fixation system	Brackets + elastics	Brackets with clips (no elastics)
Aesthetics	More visible; elastics can stain	More discreet; ceramic option available
Appointments	Requires frequent elastic changes	Fewer maintenance visits
Comfort	Higher friction, more discomfort	Less friction, more comfort, less pain
Treatment time	Effective, but may take longer	May shorten treatment in some cases
Oral hygiene	More plaque build-up due to elastics	Easier hygiene, less plaque accumulation
Cost	More affordable	More expensive

Which option is best for each case?

There is no universal answer to the question “Which is better, conventional or self-ligating braces?” Both are effective, but the choice depends on several factors:

• Complexity of the clinical case

• Patient’s age

• Aesthetic expectations

• Treatment duration

• Budget

The role of the specialist is crucial. Dr Cláudio Alferes evaluates each situation individually, explains the differences clearly, and recommends the solution that will achieve the best results with the greatest comfort and efficiency.

The importance of specialist follow-up

Both conventional and self-ligating braces are valid and effective options. More important than choosing the “best” appliance is trusting a specialist who can assess the case in detail and prescribe the right treatment.

At Dr Cláudio Alferes’ clinic, each patient receives an individual treatment plan designed not only to align teeth but also to ensure functional occlusion and improve quality of life.
