What is Bonwill theory?
In 1858 an American dentist, G Bonwill described an equilateral triangle, which was the basis for Bonwill’s theory of occlusion. The equilateral triangle had 100mm [4inches] formed by lines joining the medial contact point of the incisors and the centers of the mandibular condyles [1,2].
What is the Bonwill triangle?
Bonwill triangle – an equilateral triangle formed by lines from the contact points of the lower central incisors, or the medial line of the residual ridge of the mandible, to the condyle on either side and from one condyle to the other.
How do you describe occlusion?
Occlusion is defined as the way the teeth meet when the lower jaw (mandible) and upper jaw (maxilla) come together. It is how the teeth contact in any type of functional relationship.
What is articulation prosthodontics?
Waseem Bahjat Mushtaha Specialized in prosthodontics. 2. 1-dental articulation Dental articulation: It means the contact relationships of maxillary and mandibular teeth as they move against each other. This is a dynamic process.
What is balanced occlusion?
DEFINITION: Balanced occlusion is defined as “The simultaneous contact of the opposing upper and lower teeth in centric relation position and a continuous smooth bilateral gliding from the position to any eccentric positions with the normal range of mandibular function.
What is Bennett angle?
Bennett angle is the angle formed between the sagittal plane and the average path of the advancing condyle as viewed in the horizontal plane during lateral mandibular movements. The Bennett angle measures the size of the progressive mandibular lateral translation, and both terms are used interchangeably.
What are the types of occlusion?
Types of Occlusions (Bites)
- Cross Bite.
- Open Bite.
- Overbite.
- Underbite.
What is an occlusion in the brain?
When the blood flow through the artery leading to the brain aneurysm is stopped an occlusion occurs. In some cases, it may be best to stop blood flow through the artery leading to the brain aneurysm. This is known as an occlusion.
What is eccentric occlusion?
eccentric occlusion occlusion of the teeth when the lower jaw has moved from the centric position.
What are the curves of occlusion?
n. A curved surface that makes simultaneous contact with the major portion of the incisal and occlusal prominences of the existing teeth. The curve of a dentition on which the occlusal surfaces lie.
