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 lingualizdd tracings and the transfer of these recordings to an instrument to eliminate all potential deflective contacts in the arrangement of posterior teeth.
In this concept, a nonanatomic occlusal scheme is used with a few specific modifications. 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.
The complete denture fabrication is preceded till try in and processing of only maxillary denture is done. Author information Article notes Copyright and License information Disclaimer. Dent Clin N Am.
Contraindicated – heavy occlusal wear bruxism and abrasive diets and for young patients with good ridges. Lingualized occlusion for removable prosthodontics.
This article has been cited by other articles in PMC. 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.
A method of developing monoplane occlusions. Advantageous for patients with badly resorbed residual ridges and poor muscle function and who need treatment dentures because of rapid deteriorating or changing ridges.
Concepts of occlusion in prosthodontics: A literature review, part II
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. Sitemap What’s New Feedback Disclaimer.
Masticatory forces are directed toward the ridge bilaterally in centric occlusion [ Figure 3a ]. Accurate retentive denture bases are a requirement in this concept. In centric occlusion, the contact forces are directed toward the ridges [ Figure 2a ]. Lateral excursion Click here to view. Moving the teeth lingually and altering their vertical position may not be compatible with the tongue, lip, and cheek function.

In the right lateral position, the canine guidance disocclude the posterior teeth [ Figure 2b ]. Pivoting in the posterior region of a flat occlusal plane has been used to reduce temporomandibular joint symptoms [ Figure 4a ].
Protrusion Click here to view. Lea and Febiger; In a right lateral position, only the buccal cusps on the working side contact if the path of the condyle is not parallel to the occlusal plane.
This positioning directed forces perpendicular to the mean osseous foundation plane. If the horizontal overlap is 3—4 mm between the anterior teeth, balanced occlusion can be achieved before anterior tooth contact at maximum intercuspation.
The 2—3 mm of interocclusal clearance is not needed centric relation recorded at vertical dimension at rest with 0. In right lateral position.
The lingualized concept utilizes anatomic teeth for the maxillary denture and modified nonanatomic or semi anatomic teeth for the mandibular denture. Lineal occlusion concepts for complete dentures. Masticatory efficiency was highest for the lingualized occlusion, next highest for the balanced occlusion, and lowest ocflusion the cuspid-protected occlusion.
Anatomic posterior occlusal arrangements have the mandibular buccal cusps occluding in the maxillary central fossae and the maxillary palatal cusps occluding in the mandibular central fossae [ Figure 6a ]. In centric occlusion, the contact forces are directed toward the lingual side of the lower ridge [ Figure 5a ]. The posterior teeth were reduced in number from 8 to 6.
Then apply separating medium to obtain maxillary stone cast of generated paths. 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.
Concepts of occlusion in prosthodontics: Kurth’s concept[ 1 ] Features Artificial posterior teeth arranged incorporating the reverse lateral curve. The posterior teeth used are nonanatomic with mandibular blade form lingualozed teeth. The closures in all three types of teeth were in close proximity to the posterior border movement.
The shape of the masticatory linhualized as shown with cinephotography was not influenced greatly by occlusal form. Locating the line of occlusal contacts The linear ridge of occlusal contacts may be located in either of the dental arches. Lower teeth are arranged according to maxillary cast of generated path. Textbook of complete dentures. Thus, the teeth are lingaulized inclined to form compensatory curves. Right lateral position Click here to view.
Two-point contacts on working side are eliminated and converted to one-point contact, this increases stability and transmit forces on lingual cusps only.
