The uses of base plate wack is to:
- establish vertical dimension plane of occlusion and initial arch form in the technique for the competenture restoration.
- to form all or a portion of tray itself.
- use to produce desire contour of the denture after teeth are set in position.
True
Also referred to as bite waxes or corrective waxes they tend to distort if they are withdrawn from undercut areas.
Impression waxes
They are limited to use in and then to lose sites of the mouth or in occlusive surface areas.
Impression waxes
They are relatively soft at mouth temperature they have sufficient body to reduce the detail of soft tissues and they are rigid at room temperature.
Corrective wax
Impression waxes is referred to as?
Corrective wax and bite registration wax
Wax and combination with resins of low melting point can be used in corrective impression technique in partial and complete danger prosthesis.
Corrective wax
Availability: sheets or cakes

Corrective wax
True or false.
The uses of corrective wax is it is a wax veneer over an original impression to contact and register the details of the soft tissue.
True
It is used to record the relationship of the upper and lower teeth and dentulous patients.
Bite registration wax
Wax is often under hot running water.
Bite registration wax
Full arch, quadrant or just a few teeth can be taken
Bite registration wax
An orange colored stick wax, which is taki when melted but firm and brittle when cooled.
Sticky wax
Are used to temporarily fasten gypsum model components join and temporarily stabilize the components of a bridge before soldering or attached pieces of a broken denture prior to a repair.

Sticky wax
- it is a type of processing wax.
- if a movement occurs the wax tends to fracture than distort.
- at room temperature the wax is firm free from tackiness and brittle.
- it is the given melted with the max 5% flow at 30° c and 90% at 43° c and adheres closely to the surface when applied to it.
Sticky wax
- It is used to align fractured parts of acrylic dentures.
- It is used to align fixed partial denture units before soldering.
Sticky wax
Typically provided in pink colored flat sheets this wax is relatively soft and pliable and can easily be pressed to the desired contour around the perimeter of an impression and self sealed at the overlapped area with firm pressure.
Boxing wax
- It is a type of a processing wax
- supplied as: boxing wax as sheets and beading wax as trips
Boxing and beading boxes
Is adapted around the impression borders to create the land area of the cast.
Beading wax for this is the use of a beading wax
Is used to build up vertical walls around the impression in order to pour the gypsum product to make a cast base.
Boxing wax or the use of boxing wax
Are used for demonstration purposes. Such waxes contains synthetic and polymeric materials with additives such as fillers and coloring agents.
Carving wax and presentation wax
The pattern for the metallic framework of removable partial dentures and other similar structure is fabricated from casting waxes.
Casting wax
These waxes are available in the form of sheets, usually of 28 and 30 gauge (0.40 and 0.32mm) thickness, ready made shape, and in bulk.
Casting wax
What are the classifications according to FDI specification No. 140 in casting wax?
Class I
Class II
Class III
28 gauge, pink, flow of about 10% at 35° c, easily adaptable at 40 to 45° c.
Class I
30 gauge, green, minimum flow of 60% at 38° c, adapts well to the surface, not brittle on cooling.
Class II
Ready made shapes, blue
Class III
- Will burn out at 500° c leaving no carbon residue.
- Used to produce the metallic component of partial denture on the cast.
Casting wax
- Is a type of a processing wax
- it can be used to alter the stock tray extensions
