A Method Of Analyzing Mandibular Movement, Richard B. Mccoy

Loma Linda University Electronic Theses, Dissertations & Projects

Mandibular movement is considered to be a fundamental factor in the study, analysis, and treatment of occlusion. For many years, dentists have realized that dental health depends upon the compatibility of mandibular movements and occlusion. This realization has led to the development of new methods and techniques for recording accurately and scientifically the movements of the mandible. In order for this data to be of scientific value, it must be stored in a usable form which is easily available for analysis.

The purpose of this research project was to develop a procedure for storing and recalling mandibular-movement information. Before such …

A Procedure For The Measurement Of Glosso-Maxillary Forces, Howard L. Lilly Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this investigation was to develop a clinically feasible procedure for recording the magnitudes of glosso-maxillary forces at four palatal loci using an electronic transducer system described by Lear et, al. (1965). Of particular interest was the development of a convenient and accurate calibration device for both intraoral and extraoral application. A further object of interest was the effect an acrylic carrier plate might introduce to the magnitude of force response. Finally whether or not any significant adaptation to the carrier plate or to the transducers occurs during a reasonable testing period (six to seven hours).

A calibration …

Soft X-Rays, William F. Roherty

Bachelors’ Theses

Traditionally, radiation of those wavelengths produced by a potential of from 2 to 25kv. has been classified as "Grenz" or "soft" x-rays. The peculiar property of this radiation is its low penetrating power. While being transparent to more energetic radiation, animal tissue and similar materials are sufficiently opaque to Grenz rays as to be studied in detail. Since the radiation is of the continuous type, it can be made soft enough to reveal any object, providing, of course, that the tube window and object medium be not opaque. Soft x-rays are produced in exactly the same manner as others, except …
