Dental Malocclusion

DENTAL MALOCCLUSION

Dental malocclusion is a term that is used  when the  upper dental arch is  not aligned  with the lower one.

In other words it’s a misalignment of the upper and lower jaw.

Generally the  dental arches have a balanced relation in order to chew properly and when this balance is missing we have a malocclusion.

Consider that when we swallow a charge of 150kg operates on each side of the jaw and we do that  on average 1500 times a day.

In addition to this, dental malocclusion is also affected by any sort of dental procedure that, if not properly done can cause a misalignment in a few hours.

 

MOST RECURRING SYMPTOMS

Dental malocclusion can cause symptoms affecting the jaw, but it can also involve the spine.

The most common symptoms are:

  • Difficulty chewing
  • Face misalignment
  • Cavities
  • Gingivitis
  • Pyorrhea
  • Gum bleeding
  • Tempo-mandibular alterations
  • Open mouth breathing
  • Tinnitus
  • Dizziness
  • Ear pain
  • Chronic cough
  • Rhinosinusitis
  • Asthma
  • Chronic bronchitis
  • Back pain

 

MOST RECURRING CAUSES

Besides genetic cases, the cause of dental malocclusion can also depend on other incorrect  behaviors or pathologies as for example:

  • Sucking thumb as a child
  • Pacifier use after 3 years old
  • Prolonged baby bottle use
  • Bruxism (involuntary grinding of the teeth)
  • Chipped teeth not reconstructed
  • Mandibular fracture as a child
  • Fracture of the jaw
  • Tooth crown
  • Dental implant
  • Tooth loss
  • Mouth and jaw tumors

 

DEGREES OF MALOCCLUSION

  • 1st Degree - The bite is normal, but the upper dental arch  slightly  stands above the lower one
  • 2nd Degree - The upper dental arch prominently stands above the lower one. There is a receding  chin and a pronounced space  between the upper and lower incisors.
  • 3rd Degree - The lower jaw teeth are clearly  more forward than the upper jaw ones

 

The most frequent type of malocclusions are:

  • Different  dimensions of the upper and lower dental arch
  • Jaw dimension, too high or two small comparing to teeth shape
  • Dental crowding
  • Reverse bite (the lower  dental arch is more forward than the upper)

Posturologo, Odontoiatra e Ortodonzista lavorano insieme per analizzare e risolvere adeguatamente la corretta causa della malocclusione.

DIAGNOSIS

While some forms of dental malocclusion are evident, others can be accidentally discovered throughout  a normal routine dental visit.

In order to do a mandibular check, the doctor asks the patient to pull out the jaw and to bite and grind his teeth to check the bite and dental occlusion.

The specialist will also investigate and examine the patient’s symptoms to evaluate the  gravity of the malocclusion. Dental arches, head/skull and facial  x-rays can be required, as well as a dental impression.

After investigating and spotting malocclusions, Dentistry can be supported by Posturology and Orthodontia.

 

THERAPY

Not always dental malocclusions demand intervention, because some cases don’t have important symptoms.

In cases of more serious malocclusion, a specific intervention will be  needed through different approaches:

  • Dental brace
  • Tooth extraction
  • Bite application
  • Use of special passive brace
  • For children, avoid thumb sucking and using a pacifier after 1 year old
