Occlusal Plane

Occlusal Plane: An Important Aspect of Dental Anatomy

The occlusal plane is a significant aspect of dental anatomy that plays an important role in the functionality of our jaw and bite. This surface passes through the cutting edges of the first incisors of the lower jaw and the distal buccal cusps of the third molars, and in their absence, the second molars.

The occlusal plane determines the contact and interaction of the upper and lower teeth as the jaws close and move during chewing and speaking. This surface provides a point of contact between teeth, called the occlusal contact, which distributes chewing forces and helps prevent chewing or injury to the teeth.

The origins of the formation of the occlusal plane occur at the stage of tooth development. Proper formation of the occlusal plane requires the harmonious interaction of various structures, such as the shape of the teeth, their position in the jaw and the development of the bite. Inconsistencies in this process can lead to a variety of problems, including improper tooth alignment, injury to the jaw joints, and even functional impairment when chewing.

When performing a dental examination, assessment of the occlusal plane is an important part of diagnosis and treatment planning. Specialists such as dentists and orthodontists carefully examine the occlusal plane to identify various abnormalities such as malocclusions, discrepancies between teeth and problems with the jaw joints. This allows them to develop a customized treatment plan for the patient to restore proper bite function.

In addition, the occlusal plane can be taken into account when making dentures or orthodontic appliances. It plays an important role in ensuring stable contact between teeth and proper function when closing the jaws. Taking into account the occlusal plane when making dentures or appliances helps to achieve optimal occlusion and comfort for the patient.

In conclusion, the occlusal plane is the surface passing through the incisal edges of the mandibular first incisors and the distal buccal cusps of the third molars or second molars. It plays an important role in the functionality of the jaw and bite, and is a key aspect of dental diagnosis and treatment. Understanding the importance of the occlusal plane helps dentists and orthodontists develop effective treatment plans, providing patients with a healthy and functional bite.

What is the occlusal plane

Occlusal closure is the correct, physiological interaction of both jaws during the chewing process. It is ensured by a harmonious relationship between the length of the teeth, the location of the dentition and the contact between them. Among the three main planes, such as sagittal, transverse and frontal, occlusion includes all three and is formed individually based on the structural features of the facial skeleton and joints. Lack of contact between teeth leads to a change in the functional component of all articulatory movements. With normal clinical
