Pins In A Composite : Their Effects On The Strength Of The Material, Milton Latoni-Camarena

Loma Linda University Electronic Theses, Dissertations & Projects

The influence of pins on the compression and tensile strength of a composite resin was measured.

Compression strength was measured in cylindrical samples 8 mm long and 4 mm in diameter, using different size threaded stainless steel pins. The tensile strength was determined by compression along the diameter of cylindrical samples containing different sizes and orientations of threaded stainless steel pins.

The conventional dumbbell tensile strength was measured by pulling the mounted specimens in the direction of their long axis, using non-threaded pins.

These tests demonstrated that the compressive strength of the composite was increased 10 percent when the large …

Intentional Implantation Of Pins In The Dental Pulp Under Clinical Conditions, George C. Abraham

Loma Linda University Electronic Theses, Dissertations & Projects

This research project was directed toward the study of the histological response of human teeth to the intentional implantation of threaded stainless steel gold-plated pins.

Many different types of pins are currently used in several aspects of restorative and periodontal dentistry. In some cases there may be unintentional perforation of the dental pulp. In other cases it may be advantageous to purposely perforate the pulp for added retention.

The purpose of this research is to determine the reaction, possibilities and prognosis of such a technique under clinical conditions.

The teeth used for experimental and control groups were those recommended for …

Measurement Of The Force Of The External Pterygoid Muscles, Hajime Suya

Loma Linda University Electronic Theses, Dissertations & Projects

Much research has been done to determine closure forces of patients. This study was designed to determine the effect of certain variables on the maximum protrusive force of patients.

Custom mandibular clutches were fabricated out of blue tray resin for each patient. A clutch adaptor was fastened to the clutch to secure the weight testing apparatus. Maximum protrusive forces were recorded for each patient when the force paralleled the Frankfurt line and the angle of the eminence. This testing was accomplished with and without the use of a maxillary clutch, designed to allow the closure muscles to brace the mandibular …
