Occlusion is a fundamental concept in dentistry yet it is commonly overlooked as it's perceived as being not important or too difficult to teach and understand. Clinicians should have a sound understanding of the principles regarding occlusal harmony in order to be able to recognise and treat common problems associated with occlusal disharmony.
Lingualized occlusion is defined as a form of denture occlusion that articulates the maxillary lingual cusps with the mandibular occlusal surfaces in centric, working, and non-working mandibular positions. [1] The concept of lingualized occlusion was again influenced by Gysi, when he designed a crossbite posterior teeth model concept. [8]
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
This is an important jaw position, as it defines both the anterior-posterior and lateral relationships of the mandible and the maxilla, as well as the superior-inferior relationship known as the vertical dimension of occlusion. These are important considerations in orthodontic treatment as well as for dental prostheses and their design and use.
Vertical dimension of occlusion, or VDO, also known as occlusal vertical dimension (OVD), is a term used in dentistry to indicate the superior-inferior relationship of the maxilla and the mandible when the teeth are occluded in maximum intercuspation.
Occlusion (dentistry), the manner in which the upper and lower teeth come together when the mouth is closed; Occlusion miliaria, a skin condition; Occlusive dressing, an air- and water-tight trauma dressing used in first aid; Vascular occlusion, blockage of a blood vessel
The word derives from mal- 'incorrect' and occlusion 'the manner in which opposing teeth meet'. The malocclusion classification is based on the relationship of the mesiobuccal cusp of the maxillary first molar and the buccal groove of the mandibular first molar. If this molar relationship exists, then the teeth can align into normal occlusion.
In dentistry, a mutually protected occlusion is an occlusal scheme in which the anterior teeth protect the posterior teeth, and vice versa.. The anterior teeth protect the posterior teeth by providing for a plane of guidance during excursions, thus allowing the cusps of the posterior teeth to disclude rather than strike one another during lateral or protrusive movements from centric relation.
