Abstract

SE DESCRIBE UN TRAZADOR DENTAL QUE INCLUYE UNA SONDA (14) CON UNA PUNTA (194)QUE PUEDE MOVERSE Y TRAZAR UNA SUPERFICIE DENTAL DADA (105),LA CUAL TIENE UN DISPOSITIVO DE MONTAJE (1,2) PARA MONTAR EL TRAZADOR SOBRE UNA LOCALIZACION DE REFERENCIA ESTABLE Y DEFINIR UN PLANO BASE; UNA PRIMERA PLURALIDAD DE UNIONES (7,8,9) SUSTANCIALMENTE COPLANALES DEFINEN UN PLANO DE MOVIMIENTO; LOS ENLACES SON PIVOTABLEMENTE UNIDOS AL DISPOSITIVO DE MONTAJE, DE FORMA QUE EL PLANO DE MOVIMIENTOS HACE UN ANGULO VARIABLE CON EL PLANO BASE; UNA DE LAS UNIONES DISTALES (9) SE MUEVE EN DOS DIMENSIONES DENTRO DEL PLANO DE MOVIMIENTO; UNA CIRCUITERIA (300) GENERA SEÑALES ELECTRICAS REPRESENTATIVAS DE LOS MOVIMIENTOS DE LA PUNTA DE LA SONDA, COMO FUNCION EXCLUSIVA DE LOS MOVIMIENTOS DE LA PRIMERA PLURALIDAD; LA SEGUNDA PLURALIDAD (12,13) DE UNIONES SUJETA LA PUNTA TODO EL TIEMPO EN UNA LOCALIZACION FIJADA EN EL PLANO DE MOVIMIENTO CON RESPECTO A LA UNION DISTAL (9) DE LA PRIMERA PLURALIDAD; Y PERMITE QUE LA PIEZA DE MANO (20) SE MUEVA SOBRE LOS TRES EJES SIN QUE SE TENGA QUE MOVER LA PUNTA DE LA LOCALIZACION QUE TIENE. EL TRAZADOR COMPLETO, EXCLUSIVO DE LA PIEZA DE MANO SE ADAPTA AL TAMAÑO PARA ACOMODARSE DENTRO DE LA BOCA HUMANA.
