Real differences, indicated cases, prices, and everything you need to know before choosing, explained by our dentists in Benalmádena.
Choosing between invisible orthodontics or braces is one of the most frequent questions in consultations. Both options correct teeth, but they work in very different ways and have specific indications. As experts in orthodontics in Benalmádena, we explain everything with clinical criteria and without beating around the bush.
What is invisible orthodontics?
Invisible orthodontics, also known as aligner orthodontics, uses a series of transparent, custom-made plastic splints that are placed over the teeth and gradually move them. The best-known system is Invisalign, although there are other brands such as Spark or Angel Aligner.
How does it work in practice?

What are braces?
Conventional braces are the classic fixed orthodontic system: metal or ceramic pieces glued to the surface of the teeth and connected by an archwire. The patient does not remove them during treatment; only the orthodontist can do so in the clinic.
Most common types of braces
| Type | Material | Aesthetics | Relative Cost |
|---|---|---|---|
| Metal | Stainless steel | Visible | Low |
| Ceramic | Ceramic or sapphire | Discreet | Medium |
| Sapphire | Polycrystalline sapphire | Very discreet | Medium-High |
| Lingual | Metal (inner surface) | Invisible from outside | High |

When is invisible orthodontics recommended?
Aligners are especially suitable when these circumstances apply:
- You want total discretion: you work with the public or do not want the treatment to be noticeable.
- You have mild or moderate malocclusion: diastemas, mild crowding, simple crossbite, or minor rotations.
- You value comfort and convenience: no metal edges and generally faster adaptation.
- You play contact sports: by being able to remove them, the risk of mucosal injuries is much lower.
- They are not the best option if you require multiple extractions, skeletal corrections, or if you know you will not adhere to the wearing hours.
When are braces recommended?
- The complexity is high: severe crowding, very open or deep bites, necessary extractions.
- The patient is a child or adolescent: lack of discipline for 22 hours a day can compromise the result with aligners.
- The greatest biomechanical control is needed: in complex cases, the orthodontist manages each movement with greater precision.
- The budget is tighter: metal braces are the most economically accessible option.
The best orthodontics is not the most expensive or the most discreet. It is the one that is well indicated for your case and directed by a qualified specialist.
