Occlusion and its relationship to the function of the stomatognathic system have been widely studied in dentistry since many decades. General concepts of complete denture occlusion. Spherical concept: the anterioposterior & mesiodistal inclines of artificial teeth should be arranged. In this bilateral balanced occlusal scheme, the posterior teeth are set up at different angles in the coronal plane; 5° for the first premolar teeth, 10° for second premolar teeth, and 15° angle for both the first and second molar teeth. [9] It is asserted, based on little evidence that this scheme should be adopted for patients with compromised alveolar bone. To simplify occlusal concepts, the following principles of occlusion for complete denture are generally accepted: 1.Complete denture patients must make initial and complete occlusal contact while in centric relation. Non-anatomical teeth are set up according to curved occlusal plane both antero-posterior and laterally. 20. When such are taken to the extreme, the resulting occlusal schemes are essentially the lingulized occlusal scheme, or the Frush linear occlusion. Apart from the balanced occlusion schemes as described above, other approaches for obtaining functional occlusion in complete dentures have been proposed. March 12 - 13 . This series of articles describes about concepts of occlusion in the complete denture, fixed partial denture, and implants.

Sears of Salt Lake City, UT founded the Nonanatomic School of Complete Denture Occlusion in 1922 with the introduction of his Chewing Members. This article discusses about the evolution of different concepts of nonbalanced occlusion and occlusal schemes in complete denture occlusion. A complete denture (also known as a full denture, false teeth or plate) is a removable appliance used when all teeth within a jaw have been lost and need to be prosthetically replaced.In contrast to a partial denture, a complete denture is constructed when there are no more teeth left in an arch, hence it is an exclusively tissue-supported prosthesis. Both concepts will be explored in greater detail in the following article. The Textbook of Complete Dentures, sixth edition has been totally reformatted into a user-friendly education resource as well as an effective clinic manual. Keywords: - complete denture, occlusion, lingualized occlusion. Registration Form . 3. June 11 - 12. Historically, complete denture occlusion adopted a balanced occlusal scheme (i.e. This article discusses about the evolution of different concepts of nonbalanced occlusion and occlusal schemes in complete denture occlusion. in harmony with a spherical surface. Dietary adjustment from an abrasive to soft diet has made a major difference in function, enabling the human dentition to not work as hard as it was before. Comparisons between these schemes are also reviewed and analyzed. He believed articulation of artificial teeth was related to nine factors: He embraced the above nine factors to achieve balanced occlusion using a staggering 44 statements. This is called cenrtic occlusion.

Conflicts of Interest. Various clinical situations and their influence on linear occlusion in treating combination … (2018) compared BBO to other occlusal schemes such as CGO and lingualized occlusion (LO). 3. The aim of this scheme was to achieve cuspal contact in excursive movements such that this would improve the stability of the prostheses in lateral excursions and direct forces towards the alveolar ridges. Gen Dent 2001; 49: 374-382. Occlusion according to The Glossary of Prosthodontic Terms Ninth Edition is defined as 'the static relationship between the incising or masticating surfaces of the maxillary or mandibular teeth or tooth analogues'. Subsequently, it is difficult to state that condylar guidance is constant, and this may affect the statement that it is the only fixed factor in establishing balanced occlusion. He eliminated the plane of orientation and compensating curves from the Hanau's five main factors. This concept arose from observations of tooth wear in both human and primate dentitions. He relied on the intraoral corrections to obtain balanced occlusion. The occlusion for complete dentures discussed in this article is based on basic principles and concepts that have been studied, tested, refined, and applied successfully by dentists for years. All the concepts discuss the inclination of the condyle and the teeth in one orientation, predominantly in the sagittal direction. To achieve this result, he relays a symmetrical fixed rotation on the articulator assuming that this can be used and ideal for complex anatomical situations. [20][26] DeVan[22] argued that this occlusal scheme resulted in preservation of the alveolar bone. OCCLUSION IN COMPLETE DENTURES C P Owen Introduction Occlusion has been described as the most important subject in all the disciplines of dentistry, and for good reason, because the way the teeth come together, and function together, is as important to most of us now as it was to our ancestors, who lived on diets much more difficult to cope with. Complete Denture occlusion concepts described. Monoplane occlusion correspondingly requires having anterior teeth with no vertical overlap thus resulting in suboptimal dental aesthetics. Use of monoplane of low cusp angled teeth are advised. Using the principles of lingualized occlusion in complete dentures, it is possible to achieve lingualized balanced occlusion in a maxillary edentulous and mandibular Kennedy Class II fixed-removable rehabilitation case. Trapozzano then developed the triad of occlusion after carefully analysing Hanau's 5 factors of occlusion. Comparison of zero degree teeth and anatomic teeth on complete dentures. Occlusion and its relationship to the function of the stomatognathic system have been widely studied in dentistry since many decades. 1. 1967; 17:28-35. Complete Denture occlusion concepts described. [1] Indeed, the bilateral balanced occlusion (BBO) scheme was adopted for reconstruction of dentate patients by both the gnathology school[2] working on the West Coast of America and the Pankey-Mann Schuyler group[2][3] working on the East Coast of the United States of America[2] observed that using a balanced occlusion in dentate patients was suboptimal, in that this was associated this with restoration failure and cheek biting. Using this concept, the patient can be trained to open their mandible without movement in the condylar path, demonstrated by McCollum and this movement point located in the condyle, called hinge axis. Rehmann P., Balkenhol M., Ferger P., Wöstmann B. Ann Arbor: the University of Michigan School of Dentistry: 1973. This presentation has not concluded or recommended a superior tooth form or occlusal scheme to satisfy the requirements of completely edentulous patients with respect to comfort, mastication, phonetics, and esthetics. [20] Also, it has been argued that CPO reduces destructive lateral forces on the alveolar bone by promoting vertical chewing. J Prosthet Dent. [20] However, some studies have suggested that a monoplane occlusion can result in  reduced masticatory ability.[20][26]. Dr. Max Pleasure introduced the 'Pleasure curve' where he used a reverse Curve of Monson in the premolar area therefore generating a 'lever' balance effect. Quizlet flashcards, activities and games help you improve your grades. This article discusses about the evolution of different concepts of nonbalanced occlusion and occlusal schemes in complete denture occlusion. Jameson WS. Mehringer developed physiologically generated occlusion to harmonize complete denture occlusion, neuromuscular system, and the temporomandibular joint. From the patient's point of view, occlusal schemes are inconsequential compared to receiving the prosthesis.[7]. As a result of this, a full denture is required to restore their masticatory function. %PDF-1.5 [17] They also argued that the canine tooth possessed enhanced proprioception, thereby 'protecting' unfavourable forces on other teeth in the dentition. That is why the occlusal scheme is an important factor in the design of complete dentures. Brewer AA, Reibel PR, Nassif NJ. Therefore, in order to achieve a balanced occlusion, the compensating curves must be greater. [22][23] Monoplane occlusion involves having non-anatomic denture teeth with a 0˚ incisal guidance angle, arranged on a flat occlusal plane. Non-balanced occlusion is seen when teeth do not occlude in simultaneous contacts. The only shortcoming of the original diagram of the Hanau's quint is that Hanau suggested that the condylar guidance can be adjusted, and this created confusion for the others working in the field. This included reduction of the buccal cusp in the upper teeth and the lingual cusp of lower teeth in the frontal plane. There is a consensus that Hanau's contribution was central to evolution of the laws of articulation in order to achieve BBO. <> References. Mammals have undergone extensive changes in terms of their occlusion over time. In centric occlusion, the contact forces are directed toward This series of articles describes about concepts of occlusion in the complete denture, fixed partial denture, and implants. The concept of occlusion chosen for complete denture construction depends mainly on the esthetic requirements, masticatory efficiency and most important of it, the stability of the dentures. J Prosthodont Res, 2016;60:315-320. Then there is the much-quoted truism first cited by Boucher "Enter Bolus, Exit Balance"; whenever the patient masticates food on their working side, it negates the balance on the opposing side. in harmony with a spherical surface.

Gysi's geometrical concept underpinned bilateral occlusion schemes for both edentulous and dentate patients. Occlusion and its relationship to the function of the stomatognathic system have been widely studied in dentistry since many decades. This task is particularly challenging in complete dentures, as there is no existing occlusion to which the clinician can reference to, and as a result, it is the cause of many errors in complete denture construction. Part I and II of this articles series describe concepts and philosophies of occlusion in complete denture. Other studies show that there is another occlusion scheme that can be considered in place of the balanced occlusion.[7][10].
