The profession seems to be in "major chaos about occlusion. " This may be due to the lack of a precise classification of occlusal dysfunctions. We suggest using a classification based on the separation of three occlusal functions, with the identification of precise, objective clinical diagnostic criteria. This article aims to define a precise classification of occlusal functions, in order to be able to establish a positive diagnosis of occlusal disorders. This occlusal analysis method could then be used in the daily practice of dentists and orthodontists, with a view to align epidemiological studies that focus on occlusion, in order to obtain results capable of comparison in different studies. Materials and methods: A analysis of the literature in PubMed database published between the early 1970s and the present day identified many confusing definitions of occlusal disorders. In this paper, we propose the separation of occlusal functions into three subcategories: Stabilizing, centering, and guiding functions, defining three different subcategories of occlusal disorder. Results: Occlusal function allows the definition of three kinds of malocclusion: Stabilizing dysfunction, centering dysfunction, and guiding dysfunction. The individualization of clear subcategories could allow the study of the more pertinent impacts of pathogenic malocclusion. Conclusion: This classification of occlusal functions or dysfunctions allows lines to be drawn between different occlusal situations that are frequently confused, such as a loss of posterior occlusal support and loss of occlusal vertical dimension, infra-occlusion and loss of posterior support, short or reduced dental arch, reversed and scissor occlusion, sagittally and transversely deflected mandible, posterior occlusal interference and balancing contact, as well as natural and iatrogenic malocclusion. Clinical significance: An occlusal analysis that makes use of the three occlusal functions, "stabilizing, centering, guiding, " could offer diagnostic standardization. It may also allow the avoidance of incorrect interpretations. Therefore, this occlusal function classification may be relevant to many fields, for instance, for epidemiological studies of occlusion and the periodontium, TMD and occlusion, or TMD and orthodontic treatment.

Due to its role in the stomatognathic system and the hypothesis of the role of deep overbite in the appearance and development of TMD, particular interest is given to the incisal relationship and its evolution in urban populations.

Elle est associée à un phénomène spécifique représenté par la continuité de l'arcade caractérisée par l'absence de diastème. La loi de la tangente, proposée par Page, tente d'expliquer, par une interprétation géométrique, l'inclinaison sagittale des dents mandibulaires dans le plan sagittal. Une analyse céphalométrique de 485 sujets adultes en denture naturelle a permis une analyse statistique étudiant les axes dentaires en relation avec la loi de la tangente. L'incisive mandibulaire suit la règle orthogonale de la loi de la tangente, mais les dents mandibulaires pluricuspidées montrent un angle différentiel de leur grand axe avec la direction de la tangente. Cet angle différentiel augmente progressivement et postéro-antérieurement : 15°, 20°, 25°, 28°. Il génère une force à composante horizontale. Cette force mésialante tend à favoriser un déplacement antérieur de la dent. A chaque impact de fermeture, il existe une pression mésiale au niveau de chaque dent pluricuspidée. Cette pression assure la permanence des points proximaux. Elle est, sans doute, responsable de la dérive mésiale des arcades et participe à l'accentuation de l'encombrement incisif mandibulaire.

Pour le praticien, il est beaucoup plus difficile de bien décider que de bien agir. L'action n'étant le plus souvent que l'application de protocoles simples et reproductibles. Rien de mieux pour illustrer des difficultés de décision que des situations concrètes. La discussion de cas cliniques constituera la trame du congrès du Collège National d'Occlusodontologie (C.N.O.) de mars 2007. Le cas clinique suivant n'est qu'une illustration ponctuelle des nécessaires interrogations que se pose le praticien face à une situation concrète.

Optimal placement of the two anterior implants for the mandibular All-on-4 concept

Typically, the anterior implants are placed lingually relative to the canine/incisor teeth and perpendicular relative to the occlusal plane. According to the laws of elementary biomechanics, the long axis of the implant unit should be aligned to the axis of the occlusal loading forces during clenching in the maximal intercuspal position. When several implants are connected by a prosthesis, the mean axis of the overall occlusal loading must be taken into account. The objective of this report was to propose a different position for anterior implants by tilting them labially to counterbalance the distal inclination of the posterior implants.
