摘要：

This study aims to help the dentists in choosing the appropriate implant-prosthetic components for deficient bone. We used 3.75mm diameter implants with 8, 10, 11.5 and 13mm lengths; straight, angled 15 degrees and 25 degrees abutments and two dimensions of crowns (12 and 7.6mm). Von Mises stress decreases in cortical bone from 40.3MPa for the 8mm implant to 35.03MPa for the 13mm implant and in trabecular bone from 5.073MPa to 4.214MPa; in cortical bone is rising from 39.07MPa in the straight abutment to 56.2MPa in the 25 degrees angled abutment, while in trabecular bone from 4.78MPa to 5.371MPa; in cortical bone is rising from 40.3MPa for the 12mm crown to 46.76MPa for 7.6mm crown, while in trabecular bone from 5.073MPa to 5.932MPa. Using longer implants reduces the maximum stress values in the implant-prosthetic restoration and in bone. Stress distribution is independent to the implant's length. Using angled abutments and also reduced mesio-distal dimension crowns raises the stress, especially in cortical bone.
