Research Facts
This denture is made from acrylic resin, a material introduced into denture-making in the 20th century and still dominates today; it is light, easy to shape, and realistic looking. This type of implant, the metal screws which connect the denture to the base, were developed by Swedish surgeon Per-Ingvan Branemark in the 1960s, and they were a revolution in the field.

Research Facts
This is a Mandibular Partial Cast framework on die stone model (lower jaw)
Clasification #3 Modification #1 (bilateral space between the molar and front teeth, on different sides of the same arch)
Die stone Green (High-strength or improved stone): can withstand up to 5,000 lbs of pressure. This is normally used for partal castings or crown and bridge work for its high strength as well as preserving details within the impression. The base of model in photos 1-6 is made of regular stone (type 3) which can withstand up to 3,000 lbs of pressure. This was used as the base of the model for cost effectiveness.
Molars: because of the classification mentioned previously the molars will be used as anchors for the denture. The anchors in this casting are called akers clasps which are most commonly used because of their design. They are strong, and resistant clips that help hold the denture in place while the patient is chewing or talking.
Front teeth: normally for this design there would be clasps on the teeth that are closest to the space. However, having no clasps increases the patients esthetics but can reduce the resistance while the patient is chewing or talking.
Front teeth, metal plate: the metal plate at the back of the front teeth is known as "lingual apron" this is the major connector which means it connects one side of the arch to the other. There are many types of major connectors however this one is more commonly used. This will protect the back of the remaining teeth as well as prevent the denture from tipping during chewing or talking. This is also used incase the patient looses one of the front teeth for easy addition of another denture tooth.
Metal between the front tooth and molar: this is the area where the denture teeth will be placed. The metal is known as mesh and is used to retain the plastic base (acrylic). This is also used to connect the front part of the denture to the back teeth. Unfortunately metal and acrylic do not bond together properly so the mesh (holes) will aid in the strengh of the bond.
Cast framework: The majority of castings are made from chromem-colbalt unless specifided by dentist or denturist. Other metals such as; gold, platinum, pallidum, nickel, titanium, ticonium can be used based on the patients needs.
A framework is needed to support dentures, and can be made of resin or metal (often chrome cobalt). Metal plates are less likely to break, and are good for partial plates to be hidden behind remaining teeth, as in this model.

Research Facts
Maxillary implant retained crowns on stone model
Implants: titanium(biocompatible metal) made screw like anchor placed in the jaw bone to support crown, bridge or denture. The dentist will place the implant in a specific place in the jaw after a series of X-rays and CT scans to determind the best placement. After bone remodels around the implant it is safe to use as a functional anchor. Using an implant prior to the bone remodeling process can result in an failing implant. Which then will have to be removed. After implant is safe as a functional anchor: the dentist will place an "abutment" which will attach to crown, bridge or denture. At which time the fabrication of prosthesis will begin.
Maxillary (upper jaw) model: has four implant locators embedded in the stone. This is a precise way of knowing the angle at which the implant is placed.
Porcelain teeth: the three front teeth that are embedded in the pink material are procelin fused to metal crowns. These will be attached to the implant in the patient's mouth. (These crowns became more popular during the 1950s as gold crowns where not aesthetically pleasing. Gold crowns can be dated back to ancient Italy, and was a symbol of wealth)
The pink material is a gingiva (gum) simulated silicone which the dentist or denturist uses to replicate the tissues surrounding the implant to aid in the fabrication of the crown or bridge for esthetics or in dentures for more accurate and comfortable placement of the attachments.
Metal attachment with no tooth: this is the stage prior to the fabrication of the crown, bridge, or denture. The dental technician will now add the attachment choosen by the dentist and will fabricate a crown made of the material of the dentists choosing.
Types of crowns: porcelain fused to metal, porcelain, metal (gold, pallidum, nickel), ceramic. Ceramic crowns are more estheticly pleasing and are more used today than porcelain fused to metal.
Roughly around 1965 was the first titananium implant placement in a human, since then thousands of improvements and placements have been successful. The age of these implants are hard to say, however; it is a more recent case roughly within the last 10-15 years.
This type of implant, the metal screws which connect the denture to the base, were developed by Swedish surgeon Per-Ingvan Branemark in the 1960s, and they were a revolution in the field.

Research Facts
S. O. S. was marketed as remedy for toothaches; the label claims that the formula contained no narcotics.
S. O. S. had anaesthetic action, which means it caused insensitivity to pain; this means it was a form of pain relief, not an actual treatment for a dental condition.
The D in diamond symbol embossed on the bottom indicates the bottle itself was made by Canadian glass manufacturer Dominion Glass Company; the Dominion Glass Company factory mark, first introduced in 1940, indicates this bottle was manufactured in Hamilton, Ontario; the Dominion Glass Company diamond logo was discontinued in 1970.
