Flabby ridges displaceable tissues are a common finding in long term denture wearers. Careful management is mandatory, failing which flabby adversely affect the retention, stability and support of complete dentures. Management can be driven either surgically or prosthodontically. A list techniques has been noted literature for prosthetically managing such as Zafarullah Khan Technique, modified ...

most difficult impression to make during complete denture construction. Ill-fitting lower complete dentures are often a source of discomfort for patients. While implant retention helps to achieve vertical stability, unless a completely implant-supported denture is being made, the denture must have good tissue contact and correct anatomical extension. An impression technique is required that cap...

T ests for accuracy and other characteristics of elastic impression materials generally fall into one or more categories. These are: (1) Linear tests which measure the material itself (usually unidimensional) .le5 (2) Tests which depend upon the formation and measurement of gypsum dies made from the impression materials. In these tests, the dies are measured, not the impression material itself....

Dental impressions disinfection is important to reduce the risk of cross contamination but this process may produce dimensional distortions. Peracetic acid is a disinfectant agent with several favorable characteristics yet underutilized in Dentistry. The aim of this paper is to compare the dimensional stability of casts obtained from addition silicone and polyether impressions that were immerse...

Objectives: Dental impressions are among the potentially infectious items in dentistry. Dental impressions are invariably contaminated with saliva or blood. Such fluids may contain viral or bacterial pathogens including Bacteroides, Fusobacterium, Porphyromonas and Prevotella. The aim of this study was to assess the effects of three different types of disinfectants on alginate impression materi...

Impression procedure forms the basis of a successful Removable Partial Denture however, in distal extension bases the residual ridge must be recorded in functional form and the remaining natural teeth in an anatomic form. Zinc oxide eugenol impression paste is a material of choice for functional impression whilst irreversible hydrocolloid is suitable for an anatomic impression. Therefore two-pa...

Traditionally, soft tissue records are obtained by dental impression using materials; however, accurately recording the immediately after tooth extraction is difficult. We measured changes and compared two modalities (digital versus conventional) measuring at level. In this case, 15 patients with 17 single sites were enrolled. Conventional (CI) vinyl polysiloxane material digital (DI) an intrao...

The aim of this study was to examine the effects of tray design and impression material on impression pressure in a clinical simulation model of an edentulous mandible. Two types of polyvinylsiloxane elastomer, one type of polyether elastomer, and one type of alginate were used. The three tray types had no relief, 0.36 mm of relief, or 1.4 mm of relief, with or without escape holes. Impression ...
