ES2353769B2 - DENTAL REPRODUCTIONS OF HUMAN MORPHOLOGY FROM THE CARVING OF ANIMAL BONES FOR USE IN ACADEMIC TEACHING RESEARCH, CLINICAL PRACTICE OR INDUSTRY. - Google Patents

Abstract

Dental reproductions of human morphology a from carving animal bones for use in teaching Academic, research, clinical practice or industry.

The present invention relates to the use of long bones of animal origin in which by carving the bone cortical formation and fabrication of teeth of human morphology for use in academic teaching, research, clinical practice or industry. These Dental reproductions, because they are made in bone, allow, with clear advantages over other materials, to practice cavities, fillings and other dental treatments with equal instruments and products as described in any dentistry manual.

Description

Dental reproductions of human morphology a from carving animal bones for use in teaching Academic, research, clinical practice or industry.

Background

Before facing dental reconstruction with patients, the dentistry student must go through a preclinical learning where you become familiar with the correct anatomy and morphology of the various human teeth. In this learning, different dental reproductions are made available to the student, so far of non-bone origin, to practice the treatments that in the future they will perform on the teeth of their patients.

From the arrival of dental studies to the universities have used various techniques and diverse materials to familiarize the student with dental morphology which then has to rebuild in the destroyed teeth of the patients Represented an important milestone, for teaching, the manufacture of large dental models (1 meter approx.) by G. V. Black at the end of the 19th century, where it was learned the morphology and the correct treatment of caries. In the Spanish Stomatology Schools, as in other European schools, from the first half of the s. XX and to this day, the students of Dentistry have learned and practiced dental morphology to through the carving of soap or wax blocks, always to scale superior to the real one. More recently, they have joined the teaching dental reproductions, in real scale, performed in plastic or acrylic materials, which separately or inserted in typedontos give the student the reproduction of morphology usual dental to practice on them; having, the latter two inconveniences, one: the student is not the one who reproduces and learns the morphology of the teeth, and another: the carving of the teeth Acrylics with usual rotary instruments is very different from the one they will find when they treat natural teeth.

Description of the invention

Dental models for preclinical practices in dentistry studies that exist today have Two drawbacks: either they are larger than the real scale or they are behavioral materials very different from the structures that make up the human tooth.

We looked for a material that, for its Subsequent use in dental teaching will present the following features:

one.-

It must be an accessible material.

2.-

It must be a low cost material.

3.-

It should be an easily carved material although it It was a hard material.

4.-

It should be the most behavioral material natural-like when subjected to techniques and products Dental

The material that met all these requirements it was found in long bones of animal origin, and more specifically in bovine cane bones.

Description of the drawings

For the best understanding of how much is left written, they have been accompanied by some drawings in which they are shown some dental reproductions carved into the bone cortices of long bones of animal origin: a healthy tooth can be seen, where its correct morphology is appreciated, one where a composite sealing, a tooth where a cavity has been carved class and other where a filling with amalgam of silver. These reproductions may well remain attached to the rest. of the bone fragment forming a root crown model or well separate from the rest resulting in a dental reproduction Independent.

Carving dental reproductions of human morphology in animal bones

1) Soft tissues attached to the bone, by cooking in water and subsequent removal of mechanical form; then the bony corticals are immersed in a bath of hydrogen peroxide for the removal of these tissues from their porous cavities This specific remains disposal technique Organic has been chosen for its safety, for its ease, for the universality of its materials, due to its low cost and its appearance final, very similar to dental.

2) Fragments of these bones are cut perpendicular to the longitudinal axis of the bone, so that they measure between 5 and 7 cm and its stable support possible; then you choose a fragment of the upper surface of the bone considering the width of this cortex in relation to the piece to be carved, as well as its location in the two hemi-ellipses that represent the bone section if it is intended to recreate an arch complete.

3) It is carved with dental instruments, starting with two cuts perpendicular to the section of the cortical, by disk, separated by a distance similar to the mesio-distal and of a sagittal length similar to that of the tooth to reproduce. Its height and length are limited, the gingival areas of the crown work, inside and out of the bone, mimicking the anatomy of each face using strawberries on turbine, contra-angle or handpiece (the first being recommended); the morphology and anatomical details of each area of the model of the dental piece is achieved in a correlative or alternating way, concluding with their vestibular, lingual, mesial, distal and correct occlusal.

Claims (1)

1. The use of long bones of animal origin in the realization of dental models, by carving the bone cortices, characterized by a morphology, scale and material behavior very similar to that of the human tooth, in order to practice in them any of the Dental techniques and products, for use in academic teaching, research, clinical practice or industry.
