Although dental implant surgery is considered a somewhat predictable procedure, unforeseen accidents can occur, particularly in the posterior areas where the trabecular density is lower than the anterior. In the posterior mandible, poor bone density, loss of cortical engagement, and differences in bone quality between alveolar and basal bone could undermine the success of the treatment, resulting in a subsequent implant migration to the medullary bone marrow.\u00a0 Inadequate surgical technique\/planning, overworking of the implant bed, improper management of implant procedures along with systemic disease (osteopenia or osteoporosis), as well as the presence of lesions or cysts, can contribute to the development of the complication. To maximize bone engagement avoiding implant displacement, several precautions have been proposed. Treatment varies according to the depth of the displaced implant. In the case of superficial displacement above the inferior alveolar nerve, the crestal approach is the treatment of choice. When encountering deep displacement, a lateral approach is recommended as it provides better visibility and an improved operation field for implant retrieval.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false},"categories":[2971],"tags":[2982,2980,2978,2981,2979],"affiliation":[],"contributor":[3014,3021,3019,3011,3020,3012],"journalissue":[3141],"class_list":["post-23841","article","type-article","status-publish","hentry","category-ann-stomatol-2024-vol-42-may-august","tag-bone-marrow-defect","tag-complication","tag-displaced-implant","tag-focal-osteoporotic","tag-mandibular-corpus","contributor-a-scarano","contributor-f-inchingolo","contributor-f-tricca","contributor-s-a-gehrke","contributor-s-benedicenti","contributor-s-r-tari","journalissue-ann-stomatol-2024-vol-42-may-august"],"acf":[],"yoast_head":"\n
