balanced occlusion and Group B with lingualized occlusion. In other words, this is one of the five major determinants of balanced occlusion expressed in Hanau’s Quint and Thielemann’s formula [2, 3]. The patient’s masticatory efficiency was assessed after 2 months of denture insertion using the sieving method. 13 Condylar Guidance incisal guidance cusapl inclinantion compensating curve. Reduced trauma 4. A balanced occlusion is desirable for all removable complete denture rehabilitations. ... hanau's quint- inter-relationship of the five factors may be described by Theilman's formula, in order to maintain a balanced occlusion: hanau's quint-factors controled by the dentist. More than one third thus lacked balanced occlusion. Trapozzano reviewed Hanau's five factors and decided that only three factors were actually concerned in obtaining balanced occlusion. There are five factors involved in eccentric occlusal balance in complete denture to achieve simultaneous gliding occlusal contacts from centric occlusion to eccentric occlusal position. 5. with. bilaterally balanced occlusion and 16 (53.3%) patients in lingualized occlusion. He eliminated the plane of orientation since its location is highly variable within the available inner ridge space. We discuss occlusal schemes later in the chapter, but Box 4-1 gives a flavour of their history. balanced occlusion = (condylar inclination x incisal guidance)/(occlusal plane x cuspal inclination x compensating curve) of hannaus quint what is the only factor you really cant change. 11 Factors That Affect Occlusal Balance 12 Factors Affecting Balanced Occlusion (Hanaus Quint) 1.

In centric occlusion, half of width of mandibular posterior Hanau’s Quintn Inter-relationship of these five factors may be described by Theilman’s Formulan In order to maintain a balanced occlusion: Condylar Inclination x Incisal GuidanceC= OccPlane x Cuspal Inclination x CompCurve He mathematically charted the nine factors and listed the laws of balanced articulation in a series of 44 statements. While these factors routinely go unmeasured, their contribution to a precise diagnosis can be highly significant, even to the long-term outcome of a particular case.2-5. Factors affecting balanced occlusion According to Hanau, there are five factors which affect the balanced occlusion , - Condylar guidance Is define as mandibular guidance generated by condyle and articular disc traversing the contour of the glenoid fossa. }, author={Srdjan Postic}, journal={Vojnosanitetski pregled}, year={2012}, … The definition of the term occlusion in many dictionaries only states that it is the act of closure or being closed, but some dental dictionaries (e.g., Zwemer 1) go well beyond this simple definition to include a static, morphological tooth contact relationship.It may be defined also as the contact relationship of the teeth in function or parafunction. Hanau wisely combined the original nine factors and reduced them to five: (1) condylar guidance, (2) compensating curve, (3) relative cusp height, (4) incisal guidance, and (5) plane of orien- tation. Only about 60% had optimal occlusion, and 8% had poor occlusion according to common prosthodontic criteria. Functional movement 5. Also utilization of cross-bite occlusion and a reduced length of cantilever in bucco-lingual and mesio-distal dimension with a maximum of 15mm in mandible and 10-12mm in maxilla have been suggested as factors to consider when establishing implant occlusion. This was interpreted as a continuing impairment of the occlusion with time. 3. pitch. Fig. Bal-anced occlusion comprises realization of tooth contacts at the working side as well as at the balancing side, at the same time. 3.1.2.2. balanced occlusion by a curved occlusal plane anteroposteriorly and laterally … Condylar guidance Incisal guidance The occlusal plane The compensatory curves Cusp angulation 1. In the 1930s the concepts that are now referred to as gnathology were developed and essentially the importance of the bumps on the teeth were appreciated. Of the four he can control the incisal guidance and the pale of occlusion can be altered only a slight amount because of esthetic and physiologic factors. 1-Condylar guidance 2- Incisal guidance 3-Plane of occlusion Without proper knowledge of these points, the subject of “occlusion” will continually be twisted and confused. ... what are the 5 factors to a non anatomic neutrocentric set up. Balanced occlusal arrangement of artifi-cial teeth and balanced occlusion is a specific type of occlu-sion that preserves the stability of complete dentures. Without a foundational comprehension of the following 5 keys principles of physiologic occlusion the clinician is prone to making an inconclusive diagnosis and providing ineffective treatment. Refining Occlusion with Muscle Balance to Enhance Long-term Orthodontic Stability. inclines of 5° for first premolar, 10° for second premolar, and 15° for first and second molars, so that a balanced occlusion could be developed laterally as well as anteroposteriorly by the arrangement of teeth on a curved occlusal plane. The mean age in bilaterally balanced occlusion was 52.70±5.47 years and 54.83±5.97 years in lingualized occlusion. 16 Occlusion. Centric Occlusion (CO) = Intercuspation Position (ICP) Balanced Static Occlusion = Balanced Occlusion Balanced Dynamic Occlusion = Balanced Articulation. However, the natural occurrence of balanced occlusion (i.e. Occlusal concept, Occlusion INTRODUCTION Balanced occlusion involves a definite arrangement of tooth contact in harmony with the mandibular movements1. 4).
