The median weight of masti-cated peanuts was significantly low in lingualized occlusion groups than balanced occlusion groups at swallowing threshold. Lingualized occlusion is an attempt to maintain the esthetic and food-penetration advantages of the anatomic form while maintaining the mechanical freedom of the nonanatomic form. Indications 8 Processing Steps 9 Mould and Shade Selection 10 Model Orientation 12 Model Analysis 13 Anterior Tooth ... lingualized occlusion. Setting the Maxillary Cuspids Note the inclination of the anterior teeth. The lingualized occlusion concept is a variation of the bilaterally balanced occlusion concept. A typical esthetic display of the maxillary anterior teeth. … The principle challenge is to develop bilateral balanced occlusion because if the denture tips and moves during function and particularly during parafunction rapid bone loss ensues. Note the relationship between the incisal edge to the wet line of the lower lip when the patient makes a fricative sound. Note that the incisal 2/3 of the central incisors are perpendicular to the plane of occlusion In this particular patient, appropriate lip support was achieved by placing the labial surface of the central incisors on a curve coinciding with the inner edge of the land of the cast (red line). Occlusal Schemes – Lingualized Occlusion John Beumer III, DDS, MS and Michael Hamada DDS Division of Advanced Prosthodontics, Biomaterials and Hospital Dentistry UCLA School of Dentistry This program of instruction is protected by copyright ©. 22. Occlusal plane Line indicating the crest of the ridge. 31. Posterior displaceable mucosa. The curve of Spee is created by slightly elevating the distal half of the 1 st molar and by elevating the the 2 nd molar by about 15 degrees up from the occlusal plane. Author information: (1)Department of Prosthodontics, University of Pittsburgh School of Dental Medicine, Pittsburgh, PA. (2)Department of Prosthodontics, Wilford Hall USAF Medical Center, Lackland AFB, TX. 53. Pages e118-e131. Setting the Maxillary Lateral Incisors When viewed from the occlusal, the incisors should follow the same curvature as the internal aspect of the land. … Volume … In Class II patients the mandible tends to travel farther anteriorly in function than the typical Class I patient and consequently more horizontal overlap is necessary to allow for this functional movement . Lingualized Occlusion, 4. The lateral incisors should be placed similar in angulation and position to the central incisors. The results of studies that compared different occlusal schemes may well be summarized as inconclusive. Setting the Mandibular Central Incisors In the setup shown here, the initial vertical overlap chosen was 1.0 mm and the amount of horizontal overlap was 1.5 mm. Note that the cervical of the cuspids are in the towed out position. Occlusal forces more centered over ridge crest at centric occlusion position 3. Posterior Denture Tooth Set-Up Lingualized Occlusion - YouTube • It is particularly helpful when the patient places high priority on esthetics but non-anatomic occlusal scheme is indicated because oral conditions such as severe alveolar resorption, a Class II jaw relationship, or displaceable supporting tissue.
