A portable skull boiler in accordance with embodiments has a boiler basin optimally sized and configured for effective cleaning of cervid heads, with head positioning means, nose submersion means, and three or more adjustable and removable legs. The basin has one or more lids, and an adjustably positionable heat source. The skull boiler may be disassembled with all components securable in the boiler basin for transport and storage. The basin having a non rectilinear shape that conformingly receives and retains cervid heads thereby minimizing the size and volume of the basin facilitating efficient operation using minimal fuel and water, and easy transport.

A method for fabricating a pacifier having surface features replicating those of a nursing mother's nipple, wherein the nipple has a length, the method including steps of utilizing the nursing mother's nipple as a positive mold to cast a first negative mold; utilizing the first negative mold to cast a replica of the nursing mother's nipple; modifying the replica of the nursing mother's nipple so that said replica has a length greater than that of the nursing mother's nipple; utilizing the modified replica of the nursing mother's nipple as a second positive mold to cast a second negative mold; and utilizing the second negative mold to cast an extended length replica of the nursing mother's nipple.

Implementations of an artificial nail measurement system and method (artificial nail measurement) are provided. In some implementations, the artificial nail measurement may comprise a mold casting kit. In some implementations, the artificial nail measurement may further comprise a mold extraction kit. In some implementations, a method for the artificial nail measurement comprises a user receiving and using a mold casting kit to form a mold of the user's fingernails, shipping the mold to a nail technician to form a cast or replica of the user's fingernails, and the nail technician using the cast to measure the user's fingernails to select from pre-made artificial nails that then designed and shipped to the user for use.

An orthodontic retainer includes a first material forming a contact surface for the buccal, occlusal, labial, and lingual surfaces of the maxillary teeth. The first material has a number of holes formed bi-laterally in the lingual surface. The orthodontic retainer includes a second material forming a contact surface for the palatal portion of the upper arch dentition. The second material is formed with several bulges that mate with corresponding holes within the first material. A method of forming the orthodontic retainer includes casting an impression, vacuum forming a first material over the cast of the teeth, trimming the first material in proximity to the gingival contours, drilling a number of holes in a lingual surface of the first material, applying a second material to the palatal portion of the cast and the holes of the first material, and curing the second material to the first material.
