Biomechanical Stress Analysis of Mandibular First Permanent Molar; Restored with Amalgam and Composite Resin
Normal mastication with its varying magnitude and direction generates considerable reactionary stresses in teeth and their supporting tissues. The structure of the human tooth and its supporting tissues is a complex assemblage of materials of varied mechanical properties. The finite element method (FEM), a modern technique of numerical stress analysis, has the great advantage of being applicabl...
متن کاملRegeneration (Revascularization) of Immature Permanent First Molar Tooth: A Case Report
Introduction: Dental pulp health is very important during permanent dental root completion that takes place in the first three years after eruption. Any injury to the dental pulp during endodontic treatment or physical trauma causes disruption in the improvement of root formation. In this case it had been searched for a conservative treatment of permanent immature teeth. Case presentation: The...
متن کاملIn vitro toothbrushing abrasion of dental resin composites: packable, microhybrid, nanohybrid and microfilled materials.
This study evaluated weight loss and surface roughening after toothbrushing of different resin composites: one packable (Solitaire 2, Heraeus Kulzer), one microhybrid (Charisma, Heraeus Kulzer), one nanohybrid (Simile, Pentron) and one microfilled (Durafill VS, Heraeus Kulzer). Cylindrical specimens (n = 20) were prepared. Half of the samples were submitted to 60,000 strokes, at 4 Hz, with a de...
متن کاملDirect composite resin restoration of an anterior tooth: effect of fiber-reinforced composite substructure.
The aim of the study was to determine the static load-bearing capacity of fractured incisal teeth restored with the conventional adhesive-composite technique or by using fiber reinforced composites (FRC). Upper incisal teeth were prepared by cutting the incisal part of the crown horizontally. Restorations were made by three techniques. Group A (control group) was restored by reattaching the ori...
متن کاملevaluation of microleakage in composite-composite and amalgam-composite interfaces in tooth with preventive resin restoration (ex-viva).
this study addresses the question of whether conservative methods of restoration may be applied efficaciously in permanent posterior teeth with proximal lesions and intact occlusal preventive resin restoration (prr). the purpose of the present study was to assess the microleakage at amalgam-composite interface and composite-composite interface in permanent tooth with prr.thirty-five premolar te...
