What is a buccal occlusion?

What is a buccal occlusion?

A buccal occlusion is understood as occlusional dysfunction in the lateral tooth area, in which the upper premolars or molars buccally bite past their antagonists.

What is pre normal occlusion?

Angle Class III, or prenormal, occlusion is evident when the mandibular first molar is in a prenormal position compared to the normal occlusion, i.e. in front of the normal position, or in a mesial relationship (Figure 2.5).

What is altered occlusion?

Occlusal Alterations Occlusion alterations influence the TMJ and the functions of the masticatory muscles. According to Okeson,63 occlusion alterations can be associated with parafunctional habits, such as squeezing, bruxism, and clenching the teeth, which lead to muscle spasm and hyperactivity.

What does occlusion mean in medical terms?

An occlusion is a complete or partial blockage of a blood vessel. An occlusion can reduce or even stop the flow of oxygen-rich blood to downstream vital tissues like the heart, brain, or extremities.

What are the different types of occlusion?

6 Types of Occlusion

• Underbite. One of the types of occlusion is the underbite.
• Overbite. This is the complete opposite of underbite.
• Crossbite. Another type of teeth occlusion is the crossbite.
• Crowding.
• Overjet.
• Open Bite.

What is key of occlusion?

The Key to Occlusion has to do with how the Maxillary 1stMolar and the Mandibular 1stMolar come together. In ideal occlusion, the Mesio-Buccal cusp of the Maxillary 1stMolar occludes in the Developmental Groove of the Mandibular 1stMolar. This is known as Class I occlusion. However, not all occlusion is ideal.

What is normal overjet and overbite?

The normal range of overjet and overbite is considered as 2-4 mm. The English variation tends towards increased overjet and overbite, while the Iraqi variation tends towards lower values for both parameters.

How do you use articulating paper?

Place the articulating paper on both sides of the mouth and say to the patient, “Bite together tapping your teeth twice up and down, tap, tap.” If they start grinding, ask the patient not to grind but instead tap up and down, with all teeth together. Usually, they will get the hang of this quickly.

What is static occlusion?

Static occlusion is the study of contacts between the teeth when the jaw is not moving. The contacts are points (seen as dots when articulating paper is used). For example, close your teeth in your intercuspal position (i.e. where they meet best).

What is static and dynamic occlusion?

Static occlusion was determined for both incisal and molar relationship. Dynamic occlusion was determined in lateral and protrusive movements of the mandible.

What is the relationship between occlusion and masticatory function?

Dental occlusion is very important for masticatory function. It has been suggested that a significant relationship exists between alterations in the masticatory system and dental occlusion. Occlusion alterations influence the TMJ and the functions of the masticatory muscles.

What are the occlusion alterations of TMJ?

Occlusion alterations influence the TMJ and the functions of the masticatory muscles. According to Okeson, 63 occlusion alterations can be associated with parafunctional habits, such as squeezing, bruxism, and clenching the teeth, which lead to muscle spasm and hyperactivity.

What are the symptoms of traumatic occlusion?

Traumatic occlusion will have one or more radiographic and clinical symptoms, containing mobility, pain in chewing and percussion, fremitus, occlusal prematurities/discrepancies, facet existence, tooth migration, chipped or fractured teeth, thermal sensitivity, PDL widening, bone loss and root resorption [13].

What is an angle Class 2 malocclusion?

An Angle class II malocclusion exists when the lower molars are displaced distally so that the mesiobuccal developmental groove fits under the distal cusp of the upper first molar or even further back, giving the profile of the classic retrognathic appearance. The Angle class III malocclusion is characterized by mandibular prognathism.
