Duplication of Dentures

Neutral Zone Dentures versus Conventional Dentures in Diverse Edentulous Periods

The objectives of this study were to compare the arrangement of teeth according to the bone support concept with the neutral zone concept, Evaluate the influence of two arrangement schemes on denture success. A total of 128 patients were equally allocated into two groups, according to period of edentulism. All groups were provided neutral zone and conventional dentures. Post insertion assessmen...

Photodynamic Disinfection of Dentures

Photodynamic disinfection is a new method for cleaning dentures of edentulous patients. It is based on the photochemical action of a photoactive dye (photosensitizer), activated by proper light in the presence of oxygen. The mechanism of photosensitization directs the generation of reactive oxygen species that destroy the pathogens. A pilot study of photodynamic disinfection of dentures was car...

The relining of complete dentures.

The relining of complete dentures involves solving all of the problems encountered in the construction of new dentures, except positioning individual teeth. The first and most important problem is to achieve a healthy condition of the tissues of the basal seat for the dentures. To do this, the patient must be without his dentures for at least 24 hours before the impressions are made. The dentis...

Removable Partial Dentures

Stress analysis of partial dentures.

Three-dimensional photoelastic stress analysis has been used to examine the stresses on disjunct partial dentures. Three types of denture were studied: tooth-borne, mucosa-borne and toothand mucosa-borne. The method of calculating the stresses is outlined and the significance of the findings is discussed. INTRODUCTION There are several ways of carrying out a stress analysis in connection with p...
