Class I (orthognathic) is considered normal occlusion. Class II (retrognathic) and III (prognathic) are considered malocclusion. Class II can have different divisions. Division I is where there are protruded anterior teeth and Division II is where there one or more retruded maxillary anterior teeth..
What does occlusion mean in anatomy?
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 the anatomy of dental occlusion?
Dental Occlusal Anatomy The maxillary palatal cusps and the mandibular facial cusps comprise the centric cusps involved in centric occlusion (discussed below). In contrast, the maxillary buccal cusp and the mandibular lingual cusps guide the mandible during the lateral excursion..
What is the concept of occlusion in dentistry?
Static concept The static relations in occlusion include centric occlusion, protrusive occlusion, right and left lateral occlusion. All of these relations must be balanced with the simultaneous contacts of all the teeth on both sides of the arch at their very first contact..
What is the meaning of dental occlusion?
Dental occlusion is how a dentist defines how your upper teeth and lower teeth come together when you close your mouth. In other words, your dental occlusion is the exact same thing as your bite. We all have different bites, depending on what we are doing or feeling at any given time..
What is the occlusal anatomy of a tooth?
Occlusal– The chewing surface of posterior teeth. Proximal – Tooth surfaces that are next to each other (i.e., distal of lateral incisor and mesial of canine)..
Development of occlusion As the primary (baby) teeth begin to erupt at 6 months of age, the maxillary and mandibular teeth aim to occlude with one another. The erupting teeth are moulded into position by the tongue, the cheeks and lips during development.
occlusion: Any contact between biting or chewing surfaces of maxillary (upper) and mandibular (lower) teeth. odontogenic: Refers to tooth-forming tissues. odontogenic cyst: See cyst. odontoplasty: Adjustment of tooth length, size, and/or shape; includes removal of enamel projections.
Dental occlusion is the relation between the surfaces of the mandibular and maxillary teeth at rest and while in function. In other words, it is the contact between teeth. The term "occlusion" actually derives from the Latin proverb occludere. It means "to close up."

Terminology
Centric occlusion
Centric occlusion (CO) is the occlusion the patient makes when they fit their teeth together in maximum intercuspation
Why Is Occlusion Important?
Without adequate knowledge of occlusion, dentists are untrained to recognise and manage symptoms of occlusal disorders
Dynamic Occlusion
The pathways along which the mandible moves are determined by the muscles of mastication and two guidance systems
The Envelope of Function
The envelope of function is defined as the 3D space contained within the envelope of motion that defines mandibular movement during masticatory
Occlusal Interferences
Occlusal interferences occur when the teeth and TMJ movements are not in harmony.11 There are four types of occlusal interference
Jaw Movements
The movement of the mandible occurs in two different ways: 1. Hinge movement 2
The Ideal Occlusion
It is important to note that we should never restore a patient to the ideal occlusion if their current malocclusion is well tolerated and non-damaging
A Quick Guide on How to Assess Occlusion
One mistake made by many dentists and dental students is the failure to assess the occlusion before placing a restoration

What is occlusion in dentistry?
Occlusion is the relationship between the maxillary and mandibular teeth at rest and in function
This is a topic that often leaves dental students and even some qualified dentists scratching their heads, and for that reason, occlusion is frequently overlooked when it comes to providing patients with dental restorations
Dentalanatomy is a field of anatomy dedicated to the study of human tooth structures. The development, appearance, and classification of teeth fall within its purview. (The function of teeth as they contact one another falls elsewhere, under dentalocclusion.)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. Normal occlusion is desirable as it allows oral functions to operate properly, provides the best esthetics and is helpful in the prevention of disease.More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest. Static occlusion refers to contact between teeth when the jaw is closed and stationary, while dynamic occlusion refers to occlusal contacts made when the jaw is moving.
Dental anatomy and occlusion
Arrangement and alignment of teeth
The dental arches are the two extiw>arches of teeth, one on each jaw, that together constitute the dentition. In humans and many other species; the superior dental arch is a little larger than the inferior arch, so that in the normal condition the teeth in the maxilla slightly overlap those of the mandible both in front and at the sides. The way that the jaws, and thus the dental arches, approach each other when the mouth closes, which is called the occlusion, determines the occlusal relationship of opposing teeth, and it is subject to malocclusion if facial or dental development was imperfect.
Dental attrition is a type of tooth wear caused by
Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging. Advanced and excessive wear and tooth surface loss can be defined as pathological in nature, requiring intervention by a dental practitioner. The pathological wear of the tooth surface can be caused by bruxism, which is clenching and grinding of the teeth. If the attrition is severe, the enamel can be completely worn away leaving underlying dentin exposed, resulting in an increased risk of dental caries and dentin hypersensitivity. It is best to identify pathological attrition at an early stage to prevent unnecessary loss of tooth structure as enamel does not regenerate.
In dentistry, contact between teeth
Occlusion, in a dental context, means simply the contact between teeth. More technically, it is the relationship between the maxillary (upper) and mandibular (lower) teeth when they approach each other, as occurs during chewing or at rest.
