Patient: The patient was a 21-year-old woman who was admitted to our hospital with a complaint of anterior esthetic disorders. She had a unilateral cleft lip and palate at birth and had a history of ...lip plasty, bone grafting, and orthodontic treatment. We performed prosthetic treatment of the maxillary anterior teeth with a porcelain laminated veneer and all-ceramic crown.Discussion: We were able to perform prosthetic treatment with high patient satisfaction by diagnostic wax-up and sharing the goal of treatment with the patient and dental technician.Conclusion: The patient remains in good condition 3 years after the final prosthesis was delivered. By using porcelain laminated veneers and all-ceramic crowns, we obtained good esthetics with minimal invasiveness.
Patient: A 74-year-old man visited our hospital because of chewing difficulties due to a mobile fixed partial denture in the maxillary right molar region and an ill-fitting removable partial denture. ...Occlusal reconstruction using a fixed dental prosthesis and a removable partial denture based on a diagnostic wax-up was performed for severe tooth wear.Discussion: The vertical dimension at occlusion was decided based on a diagnostic wax-up, and a treatment denture was fabricated for the patient to increase the vertical dimension. Occlusal reconstruction was successful through the early placement of a stable denture, which appropriately restored the occlusion. Molar occlusion was established using a removable partial denture, suggesting that it is crucial to follow the changes in the alveolar ridge and the occlusal wear.Conclusion: Occlusal reconstruction for a patient with severe attrition had a satisfactory therapeutic effect with improvement in subjective masticatory performance and oral health-related quality of life.

The plant cuticle is the first physical barrier between land plants and their terrestrial environment. It consists of the polyester scaffold cutin embedded and sealed with organic, ...solvent-extractable cuticular waxes. Cuticular wax ultrastructure and chemical composition differ with plant species, developmental stage and physiological state. Despite this complexity, cuticular wax consistently serves a critical role in restricting nonstomatal water loss. It also protects the plant against other environmental stresses, including desiccation, UVradiation, microorganisms and insects. Within the broader context of plant responses to abiotic and biotic stresses, our knowledge of the explicit roles of wax crystalline structures and chemical compounds is lacking. In this review, we summarize our current knowledge of wax biosynthesis and regulation in relation to abiotic and biotic stresses and stress responses.
La décision thérapeutique dans les cas prothétiques complexes est prise à la suite de l’analyse de tous les paramètres répertoriés à partir de l’examen clinique. Elle doit être ensuite matérialisée ...par des modèles de diagnostic, véritables maquettes de la restauration prothétique terminale et qui vont servir de fil conducteur pendant tout le traitement. De plus, ces maquettes vont également permettre la réalisation des prothèses provisoires. Étape primordiale de la restauration prothétique, la phase des provisoires permet, d’une part de restaurer les fonctions altérées et d’autre part, de tester les configurations occlusales et les choix esthétiques.
The therapeutic decision of complex prosthetic cases is made after an analysis of all the identified parameters from clinic examination. It is then confirmed using wax-up, actual scale models of the final restoration that will serve as the central reference throughout the treatment. These models will also help in the production of interim prosthesis. The temporary phase of treatment, which is of primary importance, allows the restoration of altered functions, and the testing of occlusal configurations and aesthetic decisions.
