Children's Dental Plates in Barcelona: How They Work and Effectiveness According to 2026 Protocols
What Are Orthodontic Plates and Who Needs Them?
An orthodontic plate is a removable or fixed appliance used to correct bites in children during active jaw growth. In Barcelona, following the 2026 protocols of the Catalan Dental Council, these devices are recommended for patients aged 5 to 14. Unlike braces, which are cemented to teeth, the plate works through the gentle pressure of a nickel-titanium archwire. This wire has a "shape memory" effect: it constantly tries to return to its original form, gradually moving the teeth. The appliance's main goal is not just to straighten the teeth, but to create conditions for proper jaw development, ensuring permanent teeth erupt correctly. In Catalonia, such treatments are prioritized in the public dentistry system (PADES), as they prevent complex pathologies in adulthood.
Anatomy of the Device: What Does a Dental Plate Consist Of?
A modern dental plate is a high-precision device, custom-made from individual jaw impressions. The appliance's base is made of hypoallergenic acrylic plastic, perfectly replicating the palate's or alveolar ridge's contour. The main working element is the vestibular archwire made of a nickel-titanium alloy. It wraps around the front teeth and provides their retraction (moving backward) if they protrude. An orthodontic expansion screw is built into the structure to widen the jaw. Depending on the clinical task, the screw can be placed in the sagittal or transverse plane. The plate is held on the teeth by clasps (retention elements) or special locks. In complex appliances, such as twin blocks or Andresen-Häupl activators, bite pads are used to retrain muscles, stimulating proper jaw growth.
Causes of Malocclusion in Children in Catalonia
Why are bite problems increasingly diagnosed in modern children in Barcelona? 2026 statistics from the Orthodontists' College of Catalonia point to three key causes. First is genetic predisposition: a narrow jaw or macrodontia (large teeth) is often hereditary. The second cause is impaired physiological nasal breathing. Due to allergies or adenoids, children breathe through their mouths, leading to a narrowing of the upper jaw and the formation of a so-called "adenoid face." The third cause is the early loss of primary teeth. If a baby tooth is removed early due to cavities, neighboring teeth shift into the space. Consequently, the permanent tooth lacks space and erupts out of alignment. Parafunctions (bad habits) are also important: prolonged thumb sucking or pacifier use after age 3-4 deforms the dental system.
Symptoms: When to See an Orthodontist
Parents in Barcelona should carefully monitor their child's dental development from age 5-6. The first symptoms requiring specialist consultation are quite obvious. These include visible crowding where teeth overlap, or conversely, the presence of wide gaps (trema and diastema). A worrying sign is a tooth erupting outside the dental arch—for example, on the palatal side. Pay attention to how the jaws close: if the lower jaw protrudes significantly forward (mesial bite) or is set far back (distal bite), it's a direct indication for treatment. Indirect symptoms include speech impediments (lisping), rapid enamel wear on some teeth and chips on others, and chronic cheek biting. In Catalonia, early screening is actively used: the first orthodontist visit is recommended at age 6, even if everything seems visually normal.
Diagnostics in Barcelona: The 2026 Protocol
Modern diagnostics in Barcelona clinics (including our clinic's protocols) is a mandatory step before manufacturing a plate. A doctor cannot simply "place" an appliance without a complete analysis. Diagnostics begin with a clinical examination and facial profile assessment. Then, instrumental diagnostics are performed: an orthopantomogram (OPTG), a panoramic X-ray showing all teeth, permanent tooth buds, and root condition. A teleradiograph (TRG) in lateral projection is taken to analyze jaw relationships. Afterwards, impressions are taken (today, digital intraoral scanners are often used), and diagnostic models are created based on them. Only by comparing all this data can the orthodontist determine the plate type, archwire force, and screw activation frequency. A photographic protocol (facial photos in frontal and profile views, photos of teeth) is mandatory to track treatment dynamics.
Severity Levels and Treatment Strategy Selection
Depending on the pathology's complexity, plates can be either the primary or a preparatory treatment method. For mild severity (slight inclination of one or two teeth, minor jaw narrowing), simple removable plates with one screw or a vestibular arch are used. Treatment duration in this case ranges from 6 to 12 months. For moderate severity (pronounced crowding, jaw narrowing, crossbite), plates with two screws or complex bi-maxillary appliances (twin blocks) are used. Treatment can take from 1.5 to 2.5 years. Severe pathology (cleft palate, serious skeletal anomalies) requires combined treatment: first plates for preparation, then braces, and possibly orthognathic surgery in the future. It's crucial to understand: plates are effective only during growth, up to 12-15 years. In adulthood, they are used only as retainers to maintain the result.
Types of Orthodontic Plates: From Simple to Complex
The classification of plates is extensive, and choosing the right type determines treatment success. Removable monomaxillary plates are the most common type. They have a plastic base for the upper or lower jaw and are designed to widen or narrow the dental arch. Plates with a finger spring are used to correct a single tooth's position—the spring presses on the crown, tipping it in the desired direction. Appliances with a retraction arch are effective when front teeth protrude excessively. Bi-maxillary appliances (activators) are more complex: they fit over both jaws, fixing them in the correct position during sleep and retraining muscles. Fixed plates (e.g., the Haas appliance for palatal expansion) are cemented to teeth with crowns or bands; they cannot be removed and provide strong, continuous force. In Catalonia, pre-orthodontic trainers are also popular—these are silicone devices that work on the myotherapy principle, but they belong to a different class of appliances.
Treatment Stages: From Placement to Retention
The treatment process with plates in Barcelona is strictly regulated. The first stage is preparatory: oral sanitation, caries treatment, and professional hygiene. The second stage involves taking impressions and sending them to a dental laboratory. After 1-2 weeks, the finished plate is fitted and activated. Then the adaptation stage begins: in the first 3-7 days, discomfort, hypersalivation (excessive drooling), and speech difficulties are possible—this is normal. The doctor teaches the child and parents how to correctly remove and insert the appliance, and how to turn the screw (usually once every 5-7 days). The main treatment stage lasts from one to two years, with mandatory check-ups every 1.5-2 months. After the plate is removed, the retention period begins: the result needs to be stabilized. This involves either continuing to wear the same plate, but only at night, or having a new retainer made.
Relapse Prevention and Appliance Care
To ensure treatment isn't in vain, it's important to follow care and prevention rules. Oral hygiene with a plate requires special attention. Teeth should be brushed twice daily with a soft brush, обязательно using a single-tuft brush to clean around the clasps. The plate itself must be cleaned separately—with toothpaste and a brush, and also treated with special disinfectant solutions (e.g., Corega tablets for orthodontic appliances). During meals or sports, the removable appliance should be stored only in a special ventilated container to prevent bacterial growth. To prevent relapse after the main treatment, it's crucial not to miss follow-up visits and to perform myogymnastics—a set of exercises for training the orbicularis oris muscle and tongue. This will consolidate correct muscle function and prevent teeth from returning to their original position.
Plates or Braces: What to Choose in Barcelona
This question worries every parent. In Spain, according to 2026 protocols, the choice is strictly based on age and indications. Plates are prescribed during the mixed dentition phase (ages 6 to 12), when the goal is not just to move teeth but to influence jaw growth. They are gentler, cheaper, and don't require dietary restrictions (no ban on nuts or apples, unlike with braces). But their main drawback is dependence on the child's discipline: if the child removes the plate for 22 hours a day, there will be no effect. Braces are placed in permanent dentition (after 12-14 years), when jaw growth is complete, and powerful action on each tooth is needed. They are fixed, so results are guaranteed, but care is more complex and cost is higher. Often these methods are combined: first, a plate widens the jaw and prepares space, then braces align the teeth along the arch. This is the optimal path to a perfect smile.
