Classification of the bite (occlusion) is divided into three main categories: Class I, II and III.<\/strong> This classification refers to the position of the first molars and the way in which the upper ones fit together with the lower ones<\/strong>. This is important because the classification of the bite also indicates whether there is a skeletal discrepancy, and helps determine why the bite does not fit correctly.<\/p>\n

The position of the jaws is the bony base of the bite. Therefore, if maxilla and jaw are not well aligned, we are before a malocclusion<\/strong>, and it is necessary to seek a treatment to align them. If left untreated, malocclusions can cause functional problems<\/strong> such as tooth wear, mastication and digestion problems, speech problems, jaw joint (TMJ) pain<\/a>, sleep disorders and even sleep apnea<\/a>. In addition, patients with malocclusions have an imbalance in the facial features<\/strong>, which may be more or less noticeable.<\/p>\n

Class I<\/h4>\n

\"\"<\/strong><\/p>\n

 <\/p>\n

Class I is a normal relationship between teeth, jaw and jaw<\/strong>.<\/p>\n

 <\/p>\n

This is the correct occlusion, and it gives the person a well-balanced profile in the anteroposterior plane.<\/p><\/blockquote>\n

 <\/p>\n

Class II<\/strong><\/h4>\n

\"\"<\/strong><\/p>\n

 <\/p>\n

 <\/p>\n

Class II occlusion<\/a> occurs when the lower dental arch is posterior (more towards the back of the mouth) than the upper one. <\/strong>In this malocclusion, the upper front and maxillary teeth project more forward than the lower teeth and the jaw.<\/p>\n

The profile of a patient with class II\u00a0 has a convex appearance, with a retracted chin and lower lip.<\/p><\/blockquote>\n

Class II<\/strong> problems may be due to insufficient growth of the lower jaw, excessive growth of the upper jaw or a combination of both. In many cases, class II<\/strong> problems are inherited genetically and can be aggravated by environmental factors such as finger sucking.<\/p>\n

In adults, this malocclusion<\/strong>, when skeletal, requires orthodontic treatment combined with orthognathic surgery<\/strong><\/a>.<\/p>\n

 <\/p>\n

Class III<\/strong><\/h4>\n

\"\"<\/strong><\/p>\n

 <\/p>\n

 <\/p>\n

Class III occlusion<\/a> is when the lower molars are very forward and do not fit their corresponding upper molars.<\/strong>\u00a0In this faulty relationship, the lower teeth and the jaw project more forward than the upper and maxillary teeth.<\/p>\n

In patients with this malocclusion<\/strong>, the profile has a concave appearance, with a prominent chin.<\/p><\/blockquote>\n

Class III<\/strong> problems are usually due to excessive growth in the lower jaw, a lack of upper jaw growth, or a combination of both. Like class II oclussion,<\/strong> to correct this malocclusion<\/strong> when it is skeletal, the indicated treatment is orthodontics combined with orthognathic surgery<\/strong><\/a>.<\/p>\n
