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.

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. The greatest bone loss and closure of the occlusal vertical dimension were observed in the group of denture wearers with nonanatomic posterior teeth and the least in the group wearing anatomic posterior teeth. Right lateral position Click here to view. The first and foremost concern is about the health and the preservation of the supporting structures.

Concepts of occlusion in prosthodontics: A literature review, part II

In centric occlusion, the contact forces are directed toward the lingual side of the lower ridge [ Figure 5a ]. In addition, horizontal stresses were also reduced due to the friction between opposing surfaces was decreased. The closures in all three types of teeth were in close proximity to the posterior border movement. This article discusses about the evolution of different concepts of nonbalanced occlusion and occlusal schemes in complete denture occlusion.

Characteristic of this concept is recording pantographic tracing and transferring it to articulator to eliminate deflective contacts in the posterior arrangement.

The nonanatomic group also needed the most adjustments over a 5-year period. The maxillary incisors should have sufficient vertical overlap to provide separation of the posterior teeth when the incisors are in edge-to-edge relation. The maxillary posterior teeth are rotated slightly to avoid all contact of the buccal cusps [ Figure 6b ].

Pivoting in the posterior region of a flat occlusal plane has been used to reduce temporomandibular joint symptoms [ Figure 4a ]. This arrangement reduced destructive lateral forces and to direct the masticatory forces perpendicular to the support. 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.

Forces were centralized without encroachment on the tongue space. Hardy’s concept[ 1 ] Features Nonanatomic maxillary and mandibular posterior teeth are arranged in a flat plane with a minimum overbite.

Anterior tooth position does not compromise the efforts to achieve bilateral balanced occlusion within the suggested range, and the teeth can be arranged to meet esthetic and phonetic requirements. In mediolateral direction, the teeth are set with no medial and lateral inclination. Contraindicated – heavy occlusal wear bruxism and abrasive diets and for young patients with good ridges. Selective grinding lingualizzed the maxillary buccal cusps may be needed to create a clearance between the maxillary and mandibular buccal cusps [ Figure 10 ].

Protrusion Click here to view. We need to consider all the factors such as biologic, physiologic, and mechanical that favor the stability of the denture base to avoid deflective or excessive forces transmitted to the underlying structures. Jones advocated monoplane articulation in Locating the line of occlusal contacts The linear ridge of occlusal contacts may be located in either of the dental arches.

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, occlusiin, narrow occlusal lingualizes resembling that of a line, usually articulating with opposing monoplane lingyalized.

Patients were educated not to incise or protrude. 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 occlusipn, long, narrow occlusal form resembling that of a line, usually articulating with opposing monoplane teeth.

Thus, the concept of occlusion eliminates any anteroposterior or mediolateral inclines of the teeth and directs the forces of occlusion to the posterior teeth. In this concept, a nonanatomic occlusal scheme is used with a few specific modifications.

Textbook of complete dentures. InGysi introduced the concept of lingualized articulation.

A method of developing monoplane occlusions. The differences in efficiency between lingualized and balanced occlusions and also between lingualized and cuspid-protected occlusions were significant.

This decreased the magnitude of the occlusal force and centralized it to the second occlusiin and first molar area.

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.

In centric occlusion, the contact forces are directed toward the ridges [ Figure 2a ]. Related articles Articulation balanced occlusion nonbalanced occlusion. Support Center Support Center. Teeth are arranged on a flat plane, which extends from the tip of maxillary central incisors to the top of the retromolar papilla.

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 ].

Concepts of occlusion in prosthodontics: A literature review, part II

Lea and Febiger; A literature review, part II. Tooth form was modified using flat teeth with no deflecting inclines. Because the neutrocentric technique provides an area of closure and does not lock the mandible into a single position.

Occlusion as related to complete removable prosthodontics. With lingualized occlusions, only the upper lingual cusps occlude in the mandibular central fossa.
