It could also involve the adjustment of a patient’s habits, such as chewing on objects or biting fingernails. Treatment may involve minor adjustments like eliminating a high spot on a tooth which was recently restored. Once identified, the mobility of the tooth or teeth should stop. ![]() It is important to identify and eliminate the cause of the pain and mobility. In primary occlusal trauma cases, the mobility was from an excessive force being applied to a tooth with a normal attachment apparatus, also known as a periodontally-uninvolved tooth. In order to properly treat mobility due to primary occlusal trauma, the cause of the trauma must first be eliminated. However, tooth movement typically occurs earlier and is more prevalent in secondary occlusal trauma. In both primary and secondary occlusal trauma, tooth mobility can develop over time. Meanwhile, the surface of bone which is adjacent to the tensioned side of the tooth can undergo apposition and eventually grow in size. With the center of rotation of the tooth which acts as a fulcrum, the surface of the bone adjacent to the pressured side of the tooth can experience resorption and or even disappear. The teeth continually exposed to both horizontal and vertical occlusal forces. ![]() Secondary occlusal trauma typically occurs in cases where a pre-existing periodontal condition is present. This adds harm to an already damaged system. Secondary occlusal trauma occurs when normal or excessive occlusal forces are applied to teeth which have a compromised periodontal attachment. The excessive forces can be grouped into three different categories: This can occur from parafunctional habits, such as bruxism or other chewing and biting habits. Primary occlusal trauma occurs when a great occlusal force is applied to the teeth. The two different types of occlusal trauma are primary and secondary. ![]() Microscopically, there are various features which often occur along with an occlusal trauma. There are a number of signs and symptoms which occur when occlusal trauma takes place including: In addition to a widening of the periodontal ligament, a traumatic occlusion can also cause a thickening of the cervical margin of the alveolar bone. These cases are referred to as traumatic occlusion. In cases where the change in the teeth has a negative impact on how the teeth occlude, it may result in discomfort, tenderness, pain or even cause damage to or result in movement of the teeth. When this occurs, the occlusion is changed. In situations where trauma, disease or a dental treatment alters the occlusion through the modification of the surface of the teeth, it is possible for the teeth come together differently. When the jaws close together, the relationship between the teeth is an occlusion. Occlusal trauma occurs when the teeth are damaged from excessive force and are no longer properly aligned as a result.
