Effects of early unilateral mandibular first molar extraction on condylar and ramal asymmetry

Int. j. morphol; 41 (2), 2023
SUMMARY: Craniofacial symmetry is an important factor in creating a harmonious facial appearance. Genetic and external factors may cause the formation of mandibular asymmetry. The aim of this study was to evaluate vertical mandibular asymmetries in adolescents who had unilateral mandibular first permanen...

Evaluation of the occlusal contact area of molar dental implants comparing two different thicknesses (16 μm and 200 μm) of articulating occlusal papers and forces (200 and 250 N): a pivot in vitro study

Introduction: The goal of this pilot study was to evaluate the differences between checking occlusion on implants crowns using 16 or 200 µm thickness of articulating occlusal paper, and to compare the stained occlusal area between the groups after bite forces of 200 and 250 N. Methods: It was included 1...
