A Further Finite Element Stress Analysis of Angled Abutments for an Implant Placed in the Anterior Maxilla

Figure 1

Simplified patient-specific models: A cone-beam computerized tomography scan projection of a maxillary central incisor region was obtained (a), the outline of the image was manually converted (b). Simplified patient-specific models were created by extruding the simplified cross-sectional image (c). Simplified models were used in this study (d). The geometry of the implant-abutment complex was developed based on the models described in the previous study;  α was abutment angulation (e). All models were combined by Boolean operations (f, g). (h) F: occlusal force;  β (loading angle) = 0°, 15°, and 20°. (i, j) Meshed implants and bone.
