Mechanics in the Production of Mandibular Fractures: Strain-gauge Measurements of Impacts to the Chin.

Previous publications on analysis of clinical data on jaw fractures (Hagan and Huelke, 1961, and Huelke, Burdi, and Eyman, 1961 and 1962)1-' have indicated certain definite sites of fractures from impacts to specific areas of the mandible. Results of experimental studies wherein both destructive and non-destructive testing procedures were used support certain of the clinical findings (Huelke, 1961).4' 5 It is the purpose of this paper to present information on strain-gauge measurements of human mandibles under impact and to correlate these data with previous clinical and experimental findings.
