Dentures 
Dentures, also known as false teeth, are prosthetic devices constructed to replace missing teeth, and which are supported by surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable, however there are many different denture designs, some which rely on bonding or clasping onto teeth or dental implants. There are two main categories of dentures, depending on whether they are used to replace missing teeth on the mandibular arch (lower) or the maxillary arch (upper) and how many teeth need to be replaced.
COMPLETE VS PARTIAL DENTURES:
Complete dentures replace all of the teeth for either the upper or lower
arch or for both arches.
Partial dentures can be used to replace missing teeth on a patient that has
viable teeth for the partial denture to be attached to.

HOW DENTURES ARE MADE:
Modern dentures are most often fabricated in a commercial dental laboratory or denturist using a combination of a tissue shaded powder polymethylmethacrylate acrylic (PMMA) for the tissue shaded aspect. These acrylics are available in both Heat Cured and Cold Cured types. Commercially produced acrylic teeth are widely available in hundreds of shapes and tooth colors.
The process of fabricating a denture usually begins with a dental impression or initial impression of the maxillary & mandibular ridges. Standard impression materials are used during the initial impression process. The initial impression is used to create a simple stone model that represents the maxillary and mandibular arches of the patients' mouth - this is not considered a detailed impression at this stage. Once the initial impression is taken, the stone model will be used to create a Custom Impression Tray which will be used to take a second and much more detailed and accurate impression of the patients maxillary and mandibular ridges. Polyvinylsiloxane impression material is one of several very accurate impression materials used when the final impression is taken of the maxillary & mandibular ridges. A wax rim is fabricated to assist the dentist or denturist with establishing the vertical dimension of occlusion. After this a bite registration is created to marry the position of one arch to the other.
Once the relative position of each arch to the other is known, the wax rim can be used as a base to place the selected denture teeth in correct position. This arrangement of teeth is tried in the mouth so that adjustments can be made to the Occlusion. After the occlusion has been verified by the Dentist or Denturist with the patient, and all phonetic requirements are met, the denture is processed.
Processing a denture is usually performed in a lost-wax process whereby the form of the final denture, including the acrylic denture teeth, is invested in stone. This investment is then heated, and the wax is removed through a sprue when it melts. The remaining cavity is then either filled by forced injection or pouring of the uncured denture acrylic which is either a Heat Cured or Cold-Cured type of denture acrylic. During the processing period, Heat Cured acrylics - also called Permanent Denture Acrylics, go through a process called Polymerization causing the acrylic materials to bond very tightly-and taking several hours to complete. The end result is a denture which looks much more natural, is much stronger & durable than a Cold Cured Temporary Denture, resists stains and odors and will last for many years. Cold Cured or Cold Pour Dentures-also known as Temporary Dentures, do not look very natural, are not very durable, tend to contain a high percentage of porosity and are only considered Temporary until a more permanent solution is found. These types of dentures are inferior and tend to cost much less due to their quick turn around time (usually minutes) and low cost materials and teeth. It is not suggested that a patient wear a Cold Cured denture for a long period of time, for they are prone to cracks and can break rather easily. After a curing period, the stone investment is removed, the acrylic is polished, and the denture is complete.
