The position of the teeth or types of bite is very important to the patient’s optimal health. A bad bite can lead to problems when chewing, for example, making food debris more likely to build up in certain areas of the mouth.
Over time, muscle and dental problems appear, such as muscle tension in the jaw area, cavities, gingivitis and other diseases.
Bite types are subject to Angle classification, according to the position of the dental arcades. For this, the position of the first upper molars is taken into account.
Class I obstruction
Also known as normocclusion, it is a correct position where the first molar should be wedge above and slightly in front of the first lower molar.
A person with this type of bite can present problems with crowding, cutting rotation, or other positional changes, usually located in the previous sector.
Class II Esclos
When the upper first molar erupts much earlier than the first lower molar, it is a second-degree bite.
Often, in addition to the poor position of the molars, in this type of patients is added a bad position of the upper incisors that may tilt towards the lips creating a horizontal bite or that the central incisors tilt inward and the lateral incisors outward.
Class III obstructive edema
Opposition to second-degree occlusion, in the third-degree bite of the upper first molar is a wedge behind the lower first molar.
Also known as the anterior jaw, the lower dental arch is ahead of the upper one.
