Erosive and mechanical wear of the dentition is a common problem for many patients and usually presents a challenging restorative problem to solve.The authors present a case of severe teeth erosion and wear secondary to a history of bulimia nervosa. Their use of three successive occlusal bite splints of increasing thickness allowed a gradual increase in the patient’s vertical dimension of occlu...

Aim: This study aimed to evaluate the correlation between vertical dimension of occlusion (VDO) and various facial measurements in a sample Sudanese adults. Material Methods: A total 113 dental students (33 males 80 females) with mean age 21.7±1.26 years were enrolled this study. Different including (Eye-Mouth, Eye-Eye, Eye-Ear, Ear Height) compared two different VDO: N-Gn (from tip nose chin),...

Loss of posterior teeth may cause an imbalance in the stomatognathic system. Overlay removable partial dentures (ORPD) are a reversible and relatively inexpensive treatment for patients with severely worn teeth. This paper presents a treatment with ORPD in a 55-year-old male patient who had severe attrition in the maxillary and mandibular teeth, temporomandibular joint pain and reduced vertical...

overlay removable partial denture can be used as an interim prosthesis for the patients who have lost their occlusal vertical dimension due to moderate to severe attrition resulting in functional and esthetic problems. This prosthesis is believed to allow neuromuscular adjustments to a newly adjusted VDO and also to observe the function and esthetics. ORPDs provide reversible and relatively ine...

Data on estimating the vertical dimension of occlusion（VDO）for fabricating a complete denture based tongue pressure, which is related to masticatory and swallowing functions, are scarce. This study aimed examine changes in pressure raising or lowering VDO from most comfortable position（MCP）. Ten edentulous, including Eichner C3, patients with existing dentures（six men four women; mean age, 78.6...

En tant qu’élément central de la politique nationale gestion des risques naturels, le Plan Prévention du Risque inondation (PPRi) est fondé sur une logique mono-aléa. Le val d’Orléans (VdO) concerné par l’interaction entre deux aléas naturels majeurs, les inondations et effondrements karstiques. L’existence PPRi impose aux collectivités territoriales concernées (mairies) développer un Document ...

in this paper, we study different methods of solving joint redundancy-availability optimization for series-parallel systems with multi-state components. we analyzed various effective factors on system availability in order to determine the optimum number and version of components in each sub-system and consider the effects of improving failure rates of each component in each sub-system and impr...

This paper proposes a mixed integer programming model for single-item capacitated lot-sizing problem with setup times, safety stock, demand shortages, outsourcing and inventory capacity. Due to the complexity of problem, three meta-heuristics algorithms named simulated annealing (SA), vibration damping optimization (VDO) and harmony search (HS) have been used to solve this model. Additionally, ...

The article presents the methodology of testing Continental/Siemens VDO piezoelectric injectors. To determine correctness their operation, reference characteristics were used, which, due to lack guidelines from manufacturer, constituted only base for obtained expenses and intensity fuel overflows. Simultaneously, phase active experiment was simplified by limiting number measuring points, then e...
