Dental professionals are working on creating metal-free dental implants which would eliminate the risk of developing allergies to metal among patients who need teeth restorations. Fully ceramic teeth implants are now developed in Switzerland using the technologies not available until the recent years, which meet the standards of currently used titanium implants, and may become available to public as soon as in the next 12 months.
Let us show what alternative materials and objects can be used for dental implants. Photoshop teeth made of anything you can think of - examples include stones, diamonds, knives, household appliances, shrinked cars, or even paper money. The last may give the whole new meaning to the phrase "million dollar smile". Entries showing teeth of humans or animals are accepted in this contest. Consider cropping the source images (e.g. photos of smiling celebrities) to give teeth bigger space in the entry.

This contest is fueled by the following news: Teeth are bony formations in oral cavity, serving mainly for primary chewing of food. In animals, teeth are also used for hunting or defense. In human beings, teeth play an important role in formation of speech sounds. Connective tissue, pierced with nerves and blood vessels (pulp), is available inside the teeth. Types of teeth: Deciduous or “Milk” teeth and permanent.
According to the functions, teeth are divided into 4 types:
- Bicuspid teeth (premolar or small premolar);
Number of teeth in an adult is 32. Of them, 8 are incisors, 4 canines, 8 premolars and 12 large molars.
For infants, "Deciduous" of “milk” set of teeth normally starts to appear at about six months of age. During 6 – 12 yrs, the milk teeth are gradually replaced with permanent teeth. Number of milk teeth: 20.
Three main parts of the teeth are: Root, located in special cavity of maxilla; Crown, which projects above the gums and cervix, dividing both these parts.
How does a tooth get required nutrients? It is found that an open “Root channel” is connected to the tooth and nerves, arteries and veins pass through this root channel. Nerves, arteries and veins reach the cavity of tooth or pulp through a hole at the apex of root and feed required nutrients.
- Tartar (Dental calculus);
