It was concluded that widening of the periodontal ligament was a 'functional adaptation to changes in functional requirements'.

Widening of the periodontal ligament, or PDL (also serves as a very common radiographic feature).

Microscopically, there will be a number of features that accompany occlusal trauma: Signs and symptoms Ĭlinically, there is a number of physiological results that serve as evidence of occlusal trauma:, Traumatic occlusion may cause a thickening of the cervical margin of the alveolar bone and widening of the periodontal ligament, although the latter can also be caused by other processes. When that change has a negative effect on how the teeth occlude, this may cause tenderness, pain, and damage to or movement of the teeth. When trauma, disease or dental treatment alters occlusion by changing the biting surface of any of the teeth, the teeth will come together differently, and their occlusion will change. When the jaws close, for instance during chewing or at rest, the relationship between the opposing teeth is referred to as occlusion. Occlusal trauma is the damage to teeth when an excessive force is acted upon them and they do not align properly. Because this trauma is occurring on teeth that have 30-50% bone loss, this would be classified as secondary.

As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar. For patients who are missing teeth, the treatment may include restoration using a removable denture or an implant-supported crown or bridge.Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. For a bruxer, the treatment of the patient's primary occlusal trauma could involve selective grinding of certain interarch tooth contacts or using a nightguard to protect the teeth from normal occlusal forces. It could also involve altering the patient’s habits, such as chewing on pens or biting fingernails. This could involve adjustments such as removing a high spot from a recently restored tooth. The mobile tooth or teeth should soon stop demonstrating any mobility. The cause of the pain and mobility should be identified and eliminated. This is also called a periodontally-uninvolved tooth. In cases of primary occlusal trauma, the cause of the mobility was the excessive force being applied to a tooth with a normal attachment apparatus. In order to treat mobility from primary occlusal trauma, the cause of the trauma itself needs to be eliminated.

Tooth movement occurs earlier and is more prevalent in secondary occlusal trauma. In both primary and secondary occlusal trauma, the mobility of the teeth may develop over time. While the surface of bone adjacent to the tensioned side of the tooth can undergo apposition and eventually increase in size. With the center of rotation of the tooth acting as a fulcrum, the surface of bone adjacent to the pressured side of the tooth can undergo resorption and eventually disappear. The teeth constantly experience both horizontal and vertical occlusal forces. Secondary occlusal trauma typically occurs when there is a pre-existing periodontal condition. This contributes harm to a system which is already damaged. Secondary occlusal trauma occurs when normal or excessive occlusal forces are applied to the teeth with compromised periodontal attachment. The associated excessive forces can be grouped into three categories, duration, frequency and magnitude.

This can occur from parafunctional habits, such as bruxism or chewing and biting habits. Primary occlusal trauma occurs when a greater than normal occlusal force is placed on the teeth. There are two different types of occlusal trauma, primary and secondary. Microscopically, there are various features which accompany occlusal trauma. There are a number of physiological results which are evidence of occlusal trauma. Traumatic occlusion can cause a thickening of the cervical margin of the alveolar bone in addition to a widening of the periodontal ligament. This is referred to as a traumatic occlusion. When this change in the teeth has a negative effect on how the teeth occlude, it can result in tenderness, pain and even damage the movement of the teeth. When trauma, disease or dental treatment alter the occlusion through the change of the biting surface of any of the teeth, the teeth come together in a different way. When the jaws close, during chewing or at rest, the relationship between the opposing teeth is called an occlusion. Occlusal trauma is when the teeth are damaged after excessive force and they no longer align properly.
