What is dewaxing in dentistry?
Dewaxing is the process of removing wax from the ceramic mould which is covered with wax or melting the wax pattern out of ceramic mould.
How is Flasking done in complete dentures?
The plate was bent to conform to the incisal and occlusal surfaces of all teeth. The middle portion of the flask was placed into position and sufficient stone mixed to fill the flask. The stone was vibrated into the flask to a level 10 mm over the incisal and occlusal surfaces of the teeth.
What is gingival festooning?
gin·gi·val fes·toon (jinji-văl fes-tūn) Enlargement of margins of the gingival tissues occurring in early gingival disease.
What is Flasking?
flask·ing. (flask’ing), The process of investing the cast and a wax denture in a flask preparatory to molding the denture-base material into the form of the denture.
What materials are used to make dentures?
Dentures are made from a variety of dental materials including acrylic, nylon, porcelain, resin, or metal. The denture framework is generally made from acrylic, nylon, or metal. The specific materials used to fabricate your denture framework will depend upon the type of denture you are having placed.
What are the different types of dentures?
Types of dentures
- traditional/conventional complete full dentures.
- partial dentures.
- custom dentures.
- immediate dentures.
- implant supported dentures.
- snap-in dentures.
- upper dentures.
What is porosity in denture?
The porosity is a non-desirable characteristic to the acrylic resin denture base 24 . Severe porosity can weaken the prosthesis and result in high internal stress, leading to greater vulnerability to distortion and warpage 29 .
What is wax elimination?
Description. DEWAXING OR WAX ELIMINATION IN PROCESSING OF COMPLETE DENTURE FLASKING DEWAXING PACKING are the main steps of complete denture fabrication of trial denture.
What is Flasking in prosthodontics?
The process of investing the cast and a waxed denture in a flask to make a sectional mold used to form the acrylic resin denture base. The flask is made of 3 major parts, (1) lower half (which contains the cast) (2) upper half and (3) the cover or lid.

What causes denture porosity?
Porosity in an acrylic resin denture base is often attributed to the presence of residual monomer. Beech3 and Jagger and Huggett4 indicated that residual mono- mer causes three principle effects: porosity, dimensional change through stress relief, and decreased physical properties.
What is inlay wax?
Inlay wax—A specialized dental wax that can be applied to dies to form direct or indirect patterns for the lost-wax technique, which is used for the casting of metals or hot pressing of ceramics.
