occlusal trauma

There are two types of occlusal trauma, primary and secondary.

This is usually the outcome associated with untreated secondary occlusal trauma.

Microscopically, there will be a number of features that accompany occlusal trauma:

Untreated damaging malocclusion can lead to occlusal trauma.

Clinically, there are a number of physiologic results that serve as evidence of occlusal trauma:

Occlusal trauma is a dental term that refers to the damage incurred when teeth are left in traumatic occlusion without proper treatment.

As with primary occlusal trauma, treatment may include either a removable prosthesis or implant-supported crown or bridge.

He was one of the first to classify furcation defects and the role of occlusal trauma on periodontal disease.

Primary occlusal trauma will occur when there is a normal periodontal attachment apparatus and, thus, no periodontal disease.

Bruxism is the leading cause of occlusal trauma and a significant cause of tooth loss and gum recession.

As stated, secondary occlusal trauma occurs when there is a compromised periodontal attachment and, thus, a pre-existing periodontal condition.

Primary occlusal trauma (Primary Trauma from Occlusion)

Secondary occlusal trauma occurs when normal occlusal forces are placed on teeth with compromised periodontal attachment, thus contributing harm to an already damaged system.

The view that occlusal trauma (as may occur during bruxism) is a causative factor in gingivitis and periodontitis is not widely accepted.

In secondary occlusal trauma, simply removing the "high spots" or selective grinding of the teeth will not eliminate the problem, because the teeth are already periodontally involved.

To treat mobility due to occlusal trauma, whether it be primary or secondary, the affected teeth are splinted together and to the adjacent teeth so as to eliminate their mobility.

In both primary and secondary occlusal trauma, tooth mobility might develop over time, with it occurring earlier and being more prevalent in secondary occlusal trauma.

In primary occlusal trauma, the etiology, or cause, of the mobility was the excessive force being applied to a tooth with a normal attachment apparatus, otherwise known as a periodontally-uninvolved tooth.

For a bruxer, treatment of the patient's primary occlusal trauma could involve selective grinding of certain interarch tooth contacts or perhaps employing a nightguard to protect the teeth from the greater than normal occlusal forces of the patient's parafunctional habit.

Primary occlusal trauma occurs when greater than normal occlusal forces are placed on teeth, as in the case of parafunctional habits, such as bruxism or various chewing or biting habits, including but not limited to those involving fingernails and pencils or pens.
