Tooth disorders

  • Jam
  • Open bite (incisors don’t come together when biting)
  • Deep bite (upper incisors overlap or cover the lower incisors)
  • Cross bite (e.g. upper teeth bite not before but behind lower teeth)
  • Tooth outside or inside teeth arch
  • Excessive leaning of teeth in- or outside
  • Retarded teeth
  • Supernumerery teeth
  • Lack of tooth germ

Disordres concerning the jaw

  • Underdeveloped or too big jaw
  • Underdeveloped or too big upper jaw
  • The combination of the above, disproportion between the size and location of jaws
  • Open bite
  • Deep bite
  • Dyssymmetry
  • Lips- and palate gaps

Frequent deviations we meet in adulthood

  • Overgrown or leaned teeth due to missing teeth, obstructing preparation of prothesis
  • Wandering teeth due to periodontal diseases
  • Surgery- orthodontics treatments due to jaw deformities
  • Disfunctions of mandibular joints (pain, clacking)
  • Aesthetic interventions

Why do tooth disorders shape?

1. Genetic reason

  • The size and shape of our teeth are genetically determined. However, the size of the jaw is coded by other genes. So it may occur that we inherit too big teeth with small jaw or too small teeth with big jaw resulting jamming or on the contrary gapping.
  • A great number of deviations can itself be inherited, for example the protruding, overgrown jaw (bulldog bite) let’s think of the Habsburg family. Family aggregation can be observed in many cases due to lack of germ, supernumerery teeth, or just due to gaps (lips- and palate gap).

2. Outer harms

  • Bad habits, functional disorders
  • Thumb sucking (children push the upper incisors outside with their thumbs, like a „bracing” device)
  • Tongue thrust swallowing (tongue is jamming between the two dentures by swallowing)
  • Lips-pressure swallowing (lower lip is jamming behind the upper incisors, so upper incisors lean forward, the lower ones backwards)
  • Nail chewing, pencil chewing
  • Bruxism (mainly at night, in most cases because of stress)
  • Nutrition disorders (baby doesn’t suck, doesn’ chew enough)
  • Impaired nasal breathing (when child is sick for longer time, can’t take breath through nose, breathing happens through mouth only. Accordingly, lips are always open, teeth are not supported by the muscle of lips, therefore upper incisors lean outside)
  • Premature loss of milk teeth (removal of milk teeth at least one year prior to breaking out the final teeth). Early removal of milk teeth causes a great number of disorders, because the neighbouring teeth start to wander towards the missing space and the later breaking peermanent teeth will find insufficient place, so they will stand inside or outside the denture, in worst case they are unable to grow at all and remain inside the bone. Bite may also sink causing deep bite syndrome. To prevent this phenomenen we prefer keeping teeth, on the other hand, if removal is indispensible, we used to suggest the application of site maintenance. This can be removable or fixed, small size device, doesn’t disturb children.
  • Trauma (due to accident of milk teeth the permanent tooth doesn’t break out or breaks out with abnormal poisiton).
