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.

In organic occlusion The posterior teeth should protect the anterior teeth in the centric occlusion position.

If the horizontal overlap is 3—4 mm between the anterior teeth, balanced occlusion can be achieved before anterior tooth contact at maximum intercuspation. Financial support and sponsorship Nil. Disadvantages of neutrocentric occlusion The greatest criticism of this occlusal scheme is that it is the least esthetic as there is no incisal overlap and no posterior cusps. Various concepts proposed to attain nonbalanced articulation.

Lea and Febiger; Lineal occlusion concepts for complete dentures. The need for bilateral balanced occlusion is based on more favorable stress distribution during parafunctional habits. Temporomandibular joint function and its effect on concepts of occlusion. Maxillary – nonanatomic plastic teeth; mandibular – porcelain lineal teeth This combination should wear less than does the all plastic combination.

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.

Received Jun 7; Accepted Jun They exhibit bilateral fulcrum of protrusive stability — on protrusion blade form of mandibular second molar contacts maxillary first premolar bilaterally and prevent anterior rotational contact. Accurate retentive denture bases are a occluusion in this concept. Lingualizeed for ideal occlusal patterns in complete dentures. Lingualized articulation[ 23 ] InGysi introduced the concept of lingualized articulation.

The maxillary posterior teeth are rotated slightly to avoid all contact of the buccal cusps [ Figure 6b ]. A method of developing monoplane occlusions. Therefore, the direction of force in that dental arch remains fairly constant. Where the ridges of the subjects were good, the denture base movement was minimal and approximately the same for the three types of teeth, but where the ridge was poor, there was least movement with nonanatomic teeth.

Tooth positioning for lineal occlusions Anterior – Lingualkzed vertical overlap to prevent interference in excursive movements. Indications High priority on esthetics but a nonanatomic occlusal scheme is indicated. Moving the teeth lingually and altering their vertical position may not be compatible with the tongue, lip, and cheek function.

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

In right lateral position Click here to view. The 2—3 mm of interocclusal clearance is not needed centric relation recorded at vertical dimension at rest with 0. A method of developing monoplane occlusions. Finally, the occluwion should fall at the junction of the upper and middle thirds of the retromolar pads.

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. Two-point contacts on working side are eliminated and converted to one-point contact, this increases stability and transmit forces on lingual cusps only.

A line of occlusal contacts in one dental arch opposing a flat occlusal table in the other dental arch has the potential of creating the smallest lateral component of force against the denture bases. The anterior vertical overlap is absent to provide noninterception in eccentric movements. This concept was carried out by limiting the mesiodistal extent of the occlusal table to avoid arranging the teeth over the lower molar slope inherent in the posterior portion of the residual ridge.

In the right lateral oclcusion, the buccal cusps on the working side are out of contact and the occlusal contact forces are directed toward occlision lingual side of the lower ridge. Advantages[ 3 ] Both the anatomic and nonanatomic forms are retained.

The posterior teeth were reduced in number ocdlusion 8 to 6. Flat planes in all directions with no inclination at all in respect to the underlying denture foundation.

This decreased the magnitude of the occlusal force and centralized it to the second premolar and first molar area. There was no compensating curve and no incisal guidance. The maxillary denture is esthetically equivalent to normal cuspal contours in the premolar and molar regions. Neutrocentric occlusion is especially indicated in class II retrognathicclass III Prognathicand crossbite cases. Articulation, balanced occlusion, nonbalanced occlusion. Lingjalized pitch inclination, tilt was corrected by placing the occlusal plane parallel to the underlying ridges and midway between them.

Monoplane articulation[ 25 ] Jones advocated monoplane occlusoin in Dent Clin N Am. Five year cephalometric study of mandibular ridge resorption with different posterior occlusal forms. In continuation with concepts of occlusion in prosthodontics part I where concepts developed to achieve balanced articulation were described, now the different concepts developed to attain the non balanced occlusion are described with their merits and demerits.

Pivot’s place the mandible in equilibrium by maintaining the occlusal load in the molar regions. The posterior teeth used are nonanatomic with mandibular blade form of teeth.
