28. 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). Note that the cuspids are towed out at the cervical. Lingualized Occlusion Protrusive Develop protrusive contacts as shown. 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. Multilated, tortuous ridges with an excessive denture space . Make adjustments as necessary. • With Lingualised occlusion, the esthetic result is greatly improved while still maintaining the advantages of a non-anatomic system. Consequently, little or no horizontal overlap is developed in the set up. Posterior Denture Tooth Set-Up Lingualized Occlusion - YouTube 29. 8. Key Principles on the Indications and Technique of Chronic Total Occlusion Percutaneous Coronary Intervention. Indication : Abnormal closure imbalance, pathosis, trauma, neuromuscular disturbances. ... when compared to lingualized occlusion rather than a clas-sical BO set-up. Complete Denture - Final 01 - Complete Denture - Final 01. 45. implant prosthetics). 21. Bilateral balance is primarily accomplished by the maxillary lingual cusps maintaining contact during excursions with the inclines and central fossae of the mandibular cusps. Vertical overlap 1 mm Horizontal overlap 1.5 mm, 37. Lingualizing the occlusion over the crest of the lower ridge seats both upper and lower prostheses and reduces tipping forces during function. i5Ùh=s½úØ6Ù«]ö5³e¶’U^ªan‡ä8¾€bÑD™›iô•}ûÃYö|$.y¹;w×c¡ÉøB±£y-yô÷‹ß€mŸ£öLíáÿì$kÀÈð…=glïn(!rd!hY. It is particularly helpful when the patient places high priority on esthetics but a nonanatomic occlusal scheme is indicated by oral conditions such as severe alveolar resorption, a Class II jaw relationship, or displaceable supporting tissue. Begin by positioning the appropriate protrusive insert, and check to ensure that the incisal guide pin is set at zero and in contact with the incisal guide table. diameter around the centric stop. Indications for lingualized occlusion anatomic and non-anatomic Mono-plane Bilateral-balance occlusion Advantages Class II III cross bite nonanatomic Advantages Concept of occlusion of fixed prosthodontics Two reference positions are commonly used in prosthodontics Maximum intercuspal position (MIP) Centric relation (CR) Concept of occlusion of fixed prosthodontics Maximum … l’abcence de contre indication: • Occlusion de grêle • Étiologie: hernie étranglée inguinale • Pas de signe de gravité . Make adjustments as necessary. 2. Lingualized Occlusion Indications for use Advantages High esthetic demands Good esthetics Severe mandibular ridge Freedom of non- atrophy anatomic teeth Displaceable supporting Potential for bilateral tissues balance Malocclusion Centralizes vertical Previous successful forces denture with Lingualized Minimizes tipping forces Occlusion Facilitates bolus penetration (mortar and … When you have completed this step, thoroughly cool the wax before proceeding to the next step. • If the non anatomic … Note that the maxillary lingual cusps all firmly contact the central fossae of the mandibular teeth. 52. 20. Conflicts of interest There are no conflicts of interest. It focuses on the pioneers of lingualized occlusion and their designs rather than on techniques for achieving a lingualized complete denture occlusion. Setting the Lateral Incisors and Cuspids The horizontal overlap should be consistent throughout the anterior region. Lingualized Occlusion . T-scan occlusal load analysis records were done in centric occlusion , the records was used to analyze the biting force of the denture as a Full Closure Force Movie recording, then Time vs. Force Graph of that Force Movie is accomplished. Bilateral balance is primarily accomplished by the maxillary lingual cusps maintaining contact during excursions with the inclines and central fossae of the mandibular cusps. If the nonanatomic occlusal scheme … Lingualized occlusion can be defined as, the form of denture occlusion that where the maxillary lingual cusps articulate with the mandibular occlusal surfaces(Fig1) in centric 7 working and non-working mandibular positions. INDICATIONS FOR LINGUALIZED OCCLUSION ized occlusion can be used in most denture combinations. Median difference was statis-tically significant between the groups (Mann-Whitney U test= 307, p=0.034). Light contact of the anterior teeth in protrusion enhances stability. 39. Lingualized occlusion should not be confused with placement of the mandibular teeth lingual to the ridge. diameter around the centric stop. If adjustments are necessary to achieve appropriate contact they should be done at this stage. Lingualized occlusion is developed to maintain the food-penetration advantages of the anatomic form while maintaining the mechanical freedom of the nonanatomic form. • Lingualised occlusion also can be used effectively when a complete denture opposes a removable partial denture. Lingualized Occlusion Verify working, balancing and protrusive. 50. The incisal edge of the maxillary central incisors Setting the Anterior Teeth, 17. Setting the Maxillary Cuspids When viewed from the occlusal the anterior teeth follow the curvature of the internal portion of the land. Lingualized Opposing Monoplane with Balancing Ramps Verify that all the maxillary teeth, with the exception of the lateral incisors and perhaps the cuspids, are on the plane of occlusion. 31. The three landmarks used to determine the plane of occlusion are: The midpoint of the retromolar pads bilaterally as previously marked on the mandibular cast. Balanced occlusion Our objective with this tooth form (Ivoclar Ortholingual) is to create a balanced occlusion. Instructions to Patients - 3 D. Frena - Labial and buccal frena - narrow and wide respectively - Lingual frenum - must allow for movement - or displaces easily In this set up both the lingual and buccal cusp tips of the premolars and the 1 st molar were on the plane of occlusion. 51. Materials and Preparation Setting the Maxillary Anterior Denture Teeth, 13. Lingualized Occlusion Lingualized Conventional Centric Occlusion Theoretically, there should be less lateral displacement of the denture and less lateral forces during function when using lingualized posterior denture teeth.

Note the relationship between the incisal edge to the wet line of the lower lip when the patient makes a fricative sound. The controversy about occlusion concept cannot be resolved for three reasons. 34.
