There are many kinds of dentures, including steel, titanium alloy Kouga, porcelain teeth and porcelain teeth. It is suggested that the upper and lower 6 incisors should be made of porcelain, and the upper and lower 8 molars should be made of Kouga, which is beautiful and practical, but dentists should do it separately, not together. The titanium alloy used for grinding teeth is of good quality, and the price is about 400-700 porcelain each, and the titanium alloy is between 300-500.
