and any damaged or fragmented areas are repaired with wax. The mandible is then reattached, again with wax, according to the alignment of teeth, or, if no teeth are present, by averaging the vertical dimensions between the mandible and maxilla. Undercuts (like the nasal openings) are filled in with modeling clay and prosthetic eyes are inserted into the orbits centered between the superior and inferior orbital rims. At this point, a plaster cast of the skull is prepared. Extensive detail of the preparation of such a cast is presented in the article from which these methods are presented. After the cast is set, colored plastics or the colored ends of safety matches are attached at twenty-one specific "landmark" areas that correspond to the reference data. These sites represent the average facial tissue thickness for persons of the same sex, race, and age as that of the remains. From this point on, all features are added using modeling clay. First, the facial muscles are layered onto the cast in the following order: temporalis, masseter, buccinator and occipito-frontals, and finally the soft tissues of the neck. Next, the nose and lips are reconstructed before any of the other muscles are formed. The lips are approximately as wide as the interpupillary distance. However, this distance varies significantly with age, sex, race, and occlusion. The nose is one of the most difficult facial features to reconstruct because the underlying bone is limited and the possibility of variation is expansive. The nasal profile is constructed by first measuring the width of the nasal aperture and the nasal spine. Using a calculation of three times the length of the spine plus the depth of tissue marker number five will yield the approximate nose length. Next, the pitch of the nose is determined by examining the direction of the nasal spine – down, flat, or up. A block of clay that is the proper length is then placed on the nasal spine and the remaining nasal tissue is filled in using tissue markers two and three as a guide for the bridge of the nose. The alae are created by first marking a point five millimeters below the bottom of the nasal aperture. After the main part of the nose is constructed, the alae are created as small egg-shaped balls of clay, that are five millimeters in diameter at the widest point, these are positioned on the
