What is posterior teeth Disclusion?

What is posterior teeth Disclusion?

This is called “posterior disclusion”. Separation of the posterior teeth should occur, whether the jaw moves forward or left or right from centric relation. The reason that posterior disclusion is such a desired effect is because the moment the posterior teeth separate, almost all of the elevator muscles shut off.

How do you assess dental crowding?

The amount of crowding was assessed by measuring the discrepancy, in millimetres, between the space available in the arch between the contact points of adjacent teeth and the mesio-distal width of the displaced tooth, taking care to conform to the individual’s arch form.

What does crowding mean in teeth?

Dental crowding is defined as a discrepancy between tooth size and jaw size that results in a misalignment of the tooth row. Proposed reasons for crowding include excessively large teeth, small jaws, and a combination of both.

Can teeth break from crowding?

You may get uneven wear and tear on your teeth, and some teeth may start to crack or break due to poor alignment caused by the overcrowding. Speech impediments may develop, making it harder to speak clearly.

What causes rotated teeth?

Teeth can become rotated either before they emerge or after. Probably the most common cause of teeth that emerge rotated is trauma to the mouth during the development of your teeth. But cysts and tumors (usually benign tumors like odontoma) can also cause teeth to grow out rotated.

What is the name of the chewing surfaces of posterior teeth?

Occlusal – The chewing surface of posterior teeth.

What is dental Hyperocclusion?

Definition. Contact of a tooth or restoration such that it encrouches on the interocclusal freeway space. [ from NCI]

Why do supernumerary teeth occur?

The causes of supernumerary teeth are uncertain, though factors that may contribute to their appearance include genetics, overactivity of the dental lamina (cells that initiate tooth development), disease processes, and atavism (the reappearance of a trait no longer common because of evolution).

Does overcrowding hurt?

The consequences of crowded teeth often reach far beyond your smile. Teeth crowding can cause pain in your gums, teeth, and jaws. The discomfort could even spread to your neck and shoulders. Read on for more about the factors associated with teeth crowding that can lead to aches and pain.
