Dental implants are reliable and widely used, but complications such as peri-implantitis occasionally necessitate their removal. Accidents during removal are similar to those that may occur during extraction, including displacement into another structure in the maxillofacial region. We present a rare case of accidental displacement into the submandibular space, which happened during an attempt to remove an implant.

In addition to the usual loads, fixed jacket offshore platforms can be exposed to accidental loads from ship collisions. Indentation of tubular components is a significant defect that occurs when a supply vessel collides with a jacket platform, which can affect the ultimate strength of the offshore platform. This paper performs a nonlinear dynamic analysis using ABAQUS software to evaluate the ultimate strength of a wellhead jacket platform and to investigate its structural response to two consecutive impacts from a 2700-ton ship.

A number of AI safety concerns are being increasingly discussed by experts, including misinformation, invasion of privacy, job displacement, and criminal misuse. Two exploratory studies conducted in Germany and Spain (combined n = 2864) provide evidence that the general public largely supports strict oversight over safety of commercial artificial intelligence research. Among the factors that are associated with preferences for strict oversight are age, anticipated job displacement, innovativeness, and risk, time and altruistic preferences.

Background: Sternoclavicular joint dislocation (SJD) is rare, and joint instability after dislocation easily leads to deformity, pain, and limitations in performing activities, often requiring surgical treatment. Currently, there is no ideal internal fixation method for SJD.
Case Presentation: We report the case of a 38-year-old female patient with anterior dislocation of the right sternoclavicular joint (SJ) caused by a car accident who underwent open reduction and internal fixation using the double plate technique combined with the cable technique.

Introduction: Acetabulum fractures involving both columns are complicated injuries to treat, and achieving satisfactory post operative reduction with less extensile approaches is difficult. These injuries often require dual approaches, associated with their own share of complications. The anterior intrapelvic approach (AIP) addresses both columns through a single approach, minimizing these complications.

Among the immediate complications that can occur after dental implant placement, accidental displacement within the medullary spaces of the mandibular body is a rare clinical situation. This case report describes implant displacements in the posterior mandibular region and emphasizes the importance of assessing bone density and mandibular medullary patterns prior to implant placement according to a new classification by Lekholm and Zarb modified by Rosas The case reports reported three implant displacements in type II bone of the mandibular body, as classified by Lekholm and Zarb. Following the complication, the bone was reclassified as II-B according to the modification by Rosas The implants were extracted from three female patients aged from 37 to 75 years, with only one having a medical history.
