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. [ 1 ] The masticatory system also involves the periodontium , the TMJ (and other skeletal components) and the neuromusculature, therefore the tooth contacts should not be looked ...
It is located on the mandibular (lower) arch of the mouth, and generally opposes the maxillary (upper) first molars and the maxillary 2nd premolar in normal class I occlusion. The function of this molar is similar to that of all molars in regard to grinding being the principal action during mastication, commonly known as chewing.
The mandibular first molar is the tooth located distally from both the mandibular second premolars of the mouth but mesially from both mandibular second molars. It is located on the mandibular arch of the mouth, and generally opposes the maxillary first molars and the maxillary 2nd premolar. This arrangement is known as Class I occlusion.

This interaction leads to an attachment that develops as the tooth erupts into the mouth. The occlusion, which is the arrangement of teeth and how teeth in opposite arches come in contact with one another, continually affects the formation of periodontal ligament. This perpetual creation of periodontal ligament leads to the formation of groups ...
Intercuspal position (ICP), also known as centric occlusion, is a position in which teeth occlusion plays an important role. In the majority of population, centric occlusion is said to be averagely 1 mm anterior to centric relation in the natural dentition. [5]
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]
Normal occlusion is Class I occlusion. When the teeth are biting down, the maxillary central incisors occlude with the mandibular central and lateral incisors. The contact point of the mandibular teeth is in the lingual fossa of the maxillary central incisor about 4 mm gingivally from the incisal edge. [18]
