LINGUALIZED OCCLUSION PDF

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.

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 kingualized dimension at occlusion.

The lingualized concept utilizes anatomic teeth for the maxillary denture and modified nonanatomic or semi anatomic teeth for the mandibular denture.

Masticatory efficiency was highest for the lingualized occlusion, next highest for the balanced occlusion, and lowest for the cuspid-protected occlusion. In occclusion occlusion The posterior teeth should protect the anterior teeth in the centric occlusion position. The concept of neutrocentric occlusion as related to denture stability. Author information Article notes Copyright and License information Disclaimer.

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. 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.

Dent Clin N Am ; Advanced Search Users Online: In effect, the occlusion is lingualized by the elimination of contacts on the buccal cusps and by the anteroposterior arrangement of lower posterior teeth so that their lingual surfaces are on or within the lingual side of a triangle from the mesial area of the lower cuspid to the sides of the retromolar pad.

Articulation, balanced occlusion, nonbalanced occlusion. This series of articles describes about concepts of occlusion in the complete denture, fixed partial denture, and implants. Quest for ideal occlusal patterns in complete dentures. Temporomandibular joint function and its effect on concepts of occlusion. By removing inclines, occljsion lateral forces which are destructive to the residual ridges are reduced. InKoyama, Inaba, and Yokoyama conducted a study on denture wearer preference and masticatory efficiency for balanced, organic cuspid-protectedand lingualized occlusions in three complete denture patients.

Lingualized occlusion for removable prosthodontics. Part I denture construction and initial comparison. In mediolateral direction, the teeth are set with no medial and lateral inclination. Two-point contacts on working side are eliminated and converted to one-point contact, this increases stability and transmit forces on lingual cusps only.

Disadvantages Lingualizedd premolars may appear less esthetic. Occlusal plane should be kept as high posteriorly as practical to aid in developing protrusive balancing contacts with a flat plane of occlusion.

Sitemap What’s New Feedback Disclaimer. In left lateral excursive movements, only the maxillary palatal cusps make contact.

Therefore, the direction of force in that dental arch remains fairly constant. 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. Patients were educated not to incise or protrude.

The need for bilateral balanced occlusion is based on more favorable stress distribution during parafunctional habits. 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.

Pivoting in the posterior region of a flat occlusal plane has been used to reduce temporomandibular joint symptoms [ Figure 4a ]. The anterior vertical overlap is absent to provide noninterception in eccentric movements.

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

Flat planes in all directions with no inclination at all in respect to the underlying denture foundation. Accurate retentive denture bases are a requirement in this concept.

Textbook of complete dentures. In right lateral position, only the working side pivot will contact if the path of the condyle on the balancing side is not parallel to the occlusal plane [ Figure 4b ]. Then apply separating medium to obtain maxillary stone cast of generated paths. The maxillary denture is esthetically equivalent to normal cuspal contours in the premolar and molar regions. Lineal occlusion concepts for complete dentures.

This arrangement reduced destructive lateral forces and to direct the occluusion forces perpendicular to the support.

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.

Advantages[ 3 ] Both the anatomic and nonanatomic forms are retained. In centric occlusion, occlusal contact forces are directed toward the ridges.

Forces were centralized without encroachment on the tongue space. Tilting occluson the bases may result if extreme gliding contacts are made [ Figure 3b ].
