Many philosophies of arranging denture occlusion; No definitive scientific studies Lingualized Occlusion: Contacts on centered on mandibular ridge minimizes. Lingualized Occlusion. If I had to choose the one thing that’s had the greatest effect on the success of the dentures and partial dentures I construct for my patients. Lingualized occlusion represents an established method for the development of functional and esthetic complete denture articulation. Since its introduction, the.

The maxillary posterior teeth are arranged first, and the occlusal plane must fulfill certain requirements. To direct the forces toward the center of support and to reduce the functional forces, the buccolingual width of the teeth is reduced and the number of teeth is also reduced to direct the forces in the molar and bicuspid area of support and to refrain from placing a tooth on the ridge incline.
Open in a separate window. The complete denture fabrication is preceded till try in and processing of only maxillary denture is done.

Articulation, balanced occlusion, nonbalanced occlusion. This is offsetted by narrowing of the tooth width. In right lateral position. Thus, the concept of occlusion eliminates any anteroposterior or mediolateral inclines of lingyalized teeth and directs the forces of occlusion to the posterior teeth.
Abstract This series of articles describes about concepts of occlusion in the complete denture, fixed partial denture, and implants. Lower teeth are arranged according to maxillary cast of generated path. Reduced width occ,usion the artificial teeth reduces the vertical stresses on the ridge.
Lea and Febiger; Jones advocated monoplane articulation in Conflicts of interest There are no conflicts of interest. Pivot’s place the mandible in equilibrium by maintaining the occlusal load in the molar regions. Maxillary – nonanatomic plastic teeth; mandibular – porcelain lineal lingualkzed This combination should wear less than does the all plastic combination.
Characteristic of this concept is the use of pantographic tracings and the transfer of these recordings to an instrument to eliminate all potential deflective contacts in the arrangement of posterior teeth.
This series of articles describes about concepts of occlusion in the complete denture, fixed partial denture, and implants. J Prosthet Dent ; Lingualized occlusion is developed to maintain the food-penetration advantages of the anatomic form while maintaining the mechanical freedom of the nonanatomic form.
The occlusal plane is parallel to the mean plane of odclusion denture foundation. Flat planes in all directions with no inclination at all in respect to the underlying denture foundation. In lateral mandibular position outside the masticatory movements, the cuspids should prevent contacts on all other teeth.
This decreased the magnitude of the occlusal force and centralized it to the second premolar and first molar area. Therefore, the direction of force in that dental arch remains fairly constant. Textbook of complete dentures. In centric occlusion, the occlusal contact forces are directed toward the ridges [ Figure 1a ].
Two-point contacts on linguqlized side are eliminated and converted to one-point contact, this increases stability and transmit forces on lingual cusps only. Received Jun 7; Accepted Jun Pound’s concept[ 1 ] Maxillary posterior teeth should have sharp palatal cusps which should occlude with opposing widened central fossae of the mandibular posterior teeth to eliminate the deflective occlusal contacts in processed dentures and the teeth should have gold occlusal inlays to maintain vertical dimension at occlusion.
The decision as to whether to locate the ridge of contacts in the maxillary or mandibular arch depends on the factors of denture stability and esthetics. Linear occlusion[ 9 ] The occlusal arrangement of artificial teeth, as viewed in the horizontal plane, wherein the masticatory surfaces of the mandibular posterior artificial teeth have a straight, lingualizex, narrow occlusal form resembling that of a line, usually articulating with opposing monoplane teeth.
In this concept, a nonanatomic occlusal scheme is used with a few specific modifications. Thus, the teeth are not inclined to form compensatory curves.
Masticatory forces are directed toward the ridge bilaterally in centric occlusion [ Figure 3a ]. Moving the teeth lingually and altering their vertical position may not be compatible with the tongue, lip, and cheek function.
The maxillary denture is esthetically equivalent to normal cuspal contours in the premolar and molar regions. In situations where the anterior teeth would contact before achieving the desired range of bilateral balanced occlusion, the vertical overlap of the anterior teeth lingkalized be reduced to approach an incisal guidance of zero.
Selective grinding of the maxillary buccal cusps may be needed to create a clearance between the maxillary and mandibular buccal cusps [ Figure 10 ]. Maxillary posterior teeth should have sharp palatal cusps which should occlude lingkalized opposing widened central fossae of the mandibular posterior teeth to eliminate the deflective occlusal contacts in processed dentures and the teeth should have gold occlusal inlays to maintain vertical dimension at occlusion.
Concepts of occlusion in prosthodontics: A literature review, part II
Financial support and sponsorship Nil. The differences in lingualizeed between lingualized and balanced occlusions and also between lingualized and cuspid-protected occlusions were significant.
Advanced Search Users Online: When little horizontal overlap between the anterior teeth is acceptable, then the vertical overlap must be reduced to zero to attain balanced occlusion [ Figure 8 ].
Lingualized articulation[ 23 ] InGysi introduced the concept of lingualized articulation. Ganesh Kumarand Murali Karthik. Occlusal plane should be kept as high posteriorly as practical to aid in developing protrusive balancing contacts with a flat plane of occlusion. The first and foremost concern is about the health and the preservation of the supporting structures.
