Mayan population roughly around 600 AD where they succeeded in utilizing pieces of shells as implants as a replacement for mandibular teeth. Radiographs taken in the 1970’s of Mayan mandibles show compact bone formation around the implants. Moreover‚ around 800 AD‚ a stone implant was first prepared and placed in the mandible in the early Honduran culture.13 In 1809‚ J. Maggiolo inserted a gold implant tube into a fresh extraction socket which was allowed to heal and later a crown was added. But unfortunately

Antennae’s are found on the head of the crayfish that are used for taste and touch. There is a pair of mandibles located behind the antennae. Crayfish have bilateral symmetry‚ balance of the body parts on each side of the crayfish. Gills are attached to walking legs that are feathered and help them breathe.

1: Make an Impression Distribute Styrofoam plates and permanent markers to each student Instruct students to bend the plate in half so that the top of the plate is on the inside. They need to label one half with "maxilla" and one half with "mandible". Demonstrate how to make a bite mark impression on the plate. Students will need to put the folded plate into their mouth as fall as possible and bite down on it to make a good impression. They should not bite too deep as to break through
