Disclusion

14 Mandakini M, Marriette D, Giridhar K, Abhishek P.Comparative evaluation of the curve of Spee in two age groups and its relation to posterior teeth disclusion. J Prostho Dent.

Normal curve of Spee causes total posterior disclusion on mandibular protrusion when given proper anterior guidance11.

In particular, when implementing occlusal reconstruction using orthodontic treatment in patients with suspected occlusal trauma, it is possible to achieve appropriate disclusion in the molar region by providing correct anterior guidance, and it is important to weaken the lateral occlusal force.

Once this is achieved, either by reduction enameloplasty or by addition to teeth, immediate posterior disclusion in <0.5 s should be achieved.

Co., Worth, IL, USA), directly in the oral cavity and adapted onto the maxillary central incisor teeth, obtaining disclusion of up to 1 mm between the upper and lower teeth (Figure 1) (Nassar et al., 2012).

Reduction in muscle pain was due to reduction of abnormal muscle hyperactivity because occlusal splints contacts on all of the teeth, with immediate disclusion of all posterior teeth by the anterior teeth and condylar guidance.

Lithium disilicate crowns were realized with the cross-mounting technique (Figures 18, 19, and 20): the occlusal scheme was designed with anterior guidance allowing complete disclusion in both the lateral and protrusive excursions.

These incisal tables are referred to as "Incisal tables without Disclusion".

In group A with balanced occlusion, minimum of three point contacts, 2mm overjet and 1mm overbite to keep a low angle of disclusion was established in anterior tooth setup to facilitate balanced occlusion in eccentric movement.

The disclusion of posterior teeth during mandibular eccentric movement reduces the posterior teeth contact time and precludes the consequent deleterious outcomes like attrition, fracture of posterior teeth, and periodontal diseases due to trauma from occlusion.

Disclusion of all the posterior teeth in protrusive movements.
