  • Physiologic tooth attrition is accepted as a natural change. But when pathologic changes, such as loss of occlusal vertical dimension, masticatory pain, loss of masticatory function, and loss of esthetics occur, restorative measures should be taken by dentist. A patient visited the clinic with the chief complaint of 'My lower teeth bite the palate and it hurts'. It was diagnosed as iatrogenic attrition of lower natural dentition caused by inappropriate upper restorations, resulting in traumatic overbite. Through model analysis and diagnostic wax up, increase in vertical dimension was decided. Upper and lower dentitions were restored with new prostheses. After restoration, satisfactory outcomes were achieved both in functional and esthetic aspects.

  • Patients often seek rehabilitative treatment for severely worn dentition. The etiology of noncarious tooth wear due to attrition, abrasion, and erosion is multifactorial. To treat the worn dentition, it is important to identify and eliminate and/or control the factors that contribute to excessive wear. Many situations requiring complete mouth rehabilitation present with the challenge of a lack of restorative space. To establish a correct occlusal plane and space for prostheses, it is necessary to increase vertical dimension. This may require an increase in occlusal vertical dimension. Also clinicians should be able to choose the appropriate restorative materials to achieve excellence in natural esthetics as well as proper biomechanics and durability. This article presents a method for altering occlusal vertical dimension to restore dentitions with limited restorative space due to loss of tooth structure.

  • Tooth wear is a multifactorial condition, leading to the loss of dental hard tissues. While for many years, tooth wear was a condition of little interest in daily clinical practice, nowadays this is changed. Tooth wear is becoming increasingly significant in maintaining the long-term health of the dentition. This becomes especially important when the dentition is kept relatively intact in the contemporary ageing population, and edentulism is decreasing. There is also evidence that the prevalence of tooth wear is growing. It is a natural consequence of the unidirectionality of tooth wear that it is frequently used as a means of individual age estimation. Tooth wear was very serious in ancient populations up to the medieval period. Tooth wear is thus studied in a wide variety of areas. The purpose of this paper is to summarize and analyze the many issues surrounding tooth wear through recent studies in various fields and to search for future research direction.

  • The functionally generated path (FGP) technique, first described by Meyer in 1933, is a method in the oral cavity to use the movement pathway formed by the opposing cusps within the border movement of the mandible. Using this method, an appropriate occlusal shape can be given to the patient. In this case, the FGP technique was selected to provide a bilateral balanced occlusion when restoring the edentulous maxilla that opposes the natural mandibular teeth with irregular arrangement with overdentures. In addition, in order to precisely form the occlusal surface of the posterior region with the FGP technique and to reduce the attrition of denture teeth, zirconia denture teeth, not conventional resin artificial teeth, were individually manufactured. After treatment with these materials and methods, satisfactory results were obtained for both the operator and the patient.
