A 57-year-old woman underwent cervical implant surgery for a dislocated cervical spine fracture, and she complained of continuous intractable neck pain after surgery. Eight years later, she developed a plantar skin rash, subsequently diagnosed as a metal allergy, and metal dentures were replaced with ceramic ones. The skin rash, however, persisted for four more years after that and was eventually treated with cervical implant removal. Subsequently, her skin rash and her neck pain improved simultaneously. This synchronous improvement strongly suggested that the neck pain could have been caused by a cervical implant allergy. We discuss a case of posterior cervical implant allergy that presented with neck pain and plantar skin rash years after surgery.

The primary weight-bearing structure of the proximal femur, trabecular bone, has a complex three-dimensional architecture that was previously difficult to comprehensively display. This study examined the spatial architecture of trabecular struts in the coronal, sagittal, and horizontal sections of the proximal femur using 21 cases prepared with P45 sectional plasticization. The primary compressive strut (PCS) exhibited a "mushroom-like" shape with upper and lower parts.

Purpose: Preoperative virtual planning and osteosynthesis with patient-specific implants (PSIs) have become a quotidian approach to many maxillofacial elective surgery setups. When a process is well-organized, a similar approach can be harnessed to serve the needs of exact primary reconstructions, especially in midfacial trauma cases. PSI osteosynthesis of the mandible is, however, more challenging because a mirror technique of the facial sides is often unreliable due to inherent lack of symmetry, and movement of the mandible increases the risk of loosening of the osteosynthesis.

Purpose: Children develop social-pragmatic understanding with the help of sensory, cognitive, and linguistic functions by interacting with other people. This study aimed to explore (a) associations between auditory, demographic, cognitive, and linguistic factors and social-pragmatic understanding in children who use bilateral hearing aids (BiHAs) or bilateral cochlear implants (BiCIs) and in typically hearing (TH) children and (b) the effect of the group (BiHA, BiCI, TH) on social-pragmatic understanding when the effects of demographic, cognitive, and linguistic factors are controlled for.
Method: The Pragma test was used to assess social-pragmatic understanding in 119 six-year-old children: 25 children who use BiHAs, 29 who use BiCIs, and 65 TH children.

This research is purposed to synthesize the existing evidence on implant survival rates in patients with oral potentially malignant disorders (OPMD) and assess potential risk factors associated with peri-implant disease. A comprehensive search was performed across PubMed MEDLINE, Cochrane Library, and Web of Science. This review was conducted according to the PRISMA guidelines, including studies published between 2012 and 2023.
