Maxillary deficiency

Maxillary deficiency can be transversely extended with removable screw plaques. When providing the removable screw plaques, the patient is instructed how to open them, often once every 5 days. In some cases, Hyrax screws, which are slightly larger, can be used to open the midline gap of the palate, but the type of screw is dependent on the type of malformation. Sometimes the maxilla, in addition to being small, it may be inadequately grown in the anteroposterior direction. In other words, it may be far behind its correct position. This condition requires extraoral appliances which attach to the maxillary removable plaque with elastic bands and guide the maxilla forward.

The extraoral appliances used for this purpose includes the face mask and reverse chin cup. However, other orthodontic appliances including removable intraoral plaques with rods in the front are able to extend the maxilla. These appliances can be assisted by the tongue force applied to the rods. The tongue can be used to compensate for decreased maxillary growth. Alternatively, the maxillary growth can be increased by placing mini-screws or a mini-plate in the mandible along with elastic bands and removable orthodontics or fixed orthodontics appliances in the maxilla. For further information, please visit the international articles published by Dr. Jamilian. These treatments should be performed before puberty. Surgery will be required if the patient refers after puberty.

Maxillary retrognathia and maxillary hypoplasia

If everything is finished correctly, ordinarily maxilla & mandible should be symmetrical and fit together properly. If while closing the mouth, the maxilla stays a bit behind the mandible, the individual is suffering from reverse overjet or underbite. Genetics and a parent suffering from this abnormality are one of the main causes of this problem.

If the maxilla of the patient has been worn out due to mouth breathing, the individual can suffer from a severe maxillary hypoplasia. Some factors that can cause maxillary hypoplasia are:

• Genetics and underdevelopment of the bones in the upper jaw
• Bad childhood habits such as thumb sucking and causing pressure to cheeks and eventually getting maxillary hypoplasia
• Also presence of other diseases like allergies or nasal problems which leads to mouth breathing. In this case and by mouth breathing, gradually through the negative effect of the nose and causing binary pressure to the jaws, the maxilla of the individual wears out and gets involved in this condition.

Complications of maxillary retrognathia and hypoplasia

Maxillary retrognathia and hypoplasia can have various complications. For instance, such as these:

• Crooked teeth
• The possibility of early tooth decay
• Jaw pain and disorders like chronic pain in jaw joints
• Conversion in the appearance of the teeth and jaws and cosmetic dental problems
• Disorder in biting and ingestion of food
• Speech disorders
• Low self-esteem and depression
• Breathing problems and allergies

Treatment of maxillary retrognathia and small upper jaw

The treatment of maxillary retrognathia and small upper jaw is very important for prevention and treatment of its complications. Also, it prevents the maxilla from being seen as small. Some ways to treat this are:

• Surgical approach: in this approach in order to repair the structure of the jaw and proportionate them surgery is applied. This method is mainly applied for adults.
• Non-surgical approach: in this approach the orthodontist considering the amount of abnormality and patients age, can apply various orthodontic tools. These tools are:

Palatal expanders are used to stimulate the development of the upper jaw. Removable or fixed orthodontics is applied to repair the arrangement of the teeth and treatment of the abnormalities caused by maxillary retrognathia.

Applying the orthopedic devices such as chin up or reverse chin up for reducing the speed of the lower jaws development and increasing the speed of the maxilla’s development in kids. In this approach in order to obtain the symmetry of the jaws, their development is balanced. Also it is recommended using the small removable and intra-oral device that has recently been registered and utilized by the orthodontist dr, Abdolreza Jamilian. This small device is a proper alternative for those big and extra-oral appliances like face masks.

Treatment of maxillary hypoplasia

Maxillary hypoplasia that is also called maxillary deficiency is also one of the factors that have a lot of importance for treating its complications and breathing and dental problems. Treatments are either aggressive via Applying surgery or non-aggressive like orthodontic treatments.

• Surgical: in this approach the upper jaw is expanded via surgery. And in addition possible factors causing maxillary hypoplasia are resolved.
• Non-surgical: in this approach orthodontic tools such as palatal expanders are used. This device is put on the palate of the mouth and by causing pressure and extension it expands the palate of the mouth and the maxilla. By the time passes, the width measurements of the device differ as well to create greater arch in the upper set of teeth.
