Fracture-luxations of the seventh lumbar vertebrae in two large dogs were stabilised with bone screws and methylmethacrylate. Screws inserted bilaterally into the bodies of the lumbar vertebrae and ilial wings were left protruding by about 2 cm, and embedded in methylmethacrylate bone cement. Implant failure occurred in one dog six days after surgery, necessitating a revision of the fixation. Fracture healing and return of normal ambulation occurred in both dogs. Implants were removed in one dog because of screw loosening and discomfort.

Purpose: In this randomized clinical trial, we examined the incorporation of nanogold particles into polymethyl methacrylate denture bases and compared these modified bases with conventional ones in mandibular implant-retained overdentures, focusing on microbiological growth and adhesion characteristics.
Methods: In this study, twenty-two male patients who were completely edentulous participated in a rehabilitation program involving mandibular overdentures retained by two dental implants placed in the canine area. The subjects were categorized into two equal groups, each comprising eleven patients.

Very high heat is generated during the polymerization of poly (methyl methacrylate) (PMMA) bone cement, which is used for implant fixation in orthopedic surgery. As such, it has been suggested that irrigating the bone cement layer in the surgical site with a saline solution is a way of cooling the layer. In this study, we aimed to determine the influence of irrigation with a saline solution on the flexural strength and the microstructure of the test specimens of two PMMA bone cement brands: Simplex P and FIX 1.

Aim: Percutaneous vertebroplasty is generally considered a safe procedure, however, cases of cardioembolism and cardiac perforation have been reported.
Case Presentation: A 69-year-old woman was referred to our emergency department after an outpatient echocardiogram revealed a "thrombus-like" formation involving the right heart. Two weeks before she had undergone percutaneous vertebroplasty of the third to fifth lumbar vertebrae due to osteoporotic fractures.

Background: Cementoplasty has been successfully used for treating fractures in various parts of the human body, although the use in weight-bearing long bones is a subject of controversial debate. Strategies to improve the mechanical properties of polymethylmethacrylate-based bone cement (BC) comprise changing the chemical composition or the application of metal reinforcement strategies. In clinical practice reinforced bone cement is used despite biomechanical basic research regarding this topic being scare.

Cranioplasty to restore calvarial defects involves reconstruction with alloplastic materials or autologous tissues in order to provide the best protection to all intracranial contents. Sometimes, autologous bone may not be available; therefore, different materials have emerged such as polymethylmethacrylate plate, titanium mesh, and hydroxyapatite. However, when it is impossible to replace the autologous bone, the aesthetic result is generally unsatisfactory.
