PURPOSE To investigate the modified protocol for immediate occlusal loading of the zygomatic implants and to report the preliminary results of this modified protocol. MATERIALS AND METHODS Four male patients and 1 female patient with edentulous maxillae were consecutively treated with the zygomatic implants under general anesthesia. All 5 patients were examined by computed tomography and inve...

PURPOSE To evaluate the efficacy of associating techniques of bone grafting in the maxillary sinus with the use of a prototyped surgical guide for planning and positioning dental implants in total edentulous maxillae, rehabilitated after six months. METHODS Eight patients consecutives with totally edentulous maxilla presenting few remaining bone in the posterior alveolar ridge, associated wit...

primary breast lymphoma represents less than 1% of all primary breast malignancies and most primary breast lymphomas are of b-cell origin. the association of anaplastic lymphoma kinase (alk) negative anaplastic large cell lymphoma (alcl), a very rare form of primary breast lymphoma, with silicone-filled breast implants has been suggested and several case reports supported this proposal, especia...

This paper summarizes several cases of metallurgical failure analysis of surgical implants conducted at the Laboratory of Failure Analysis, Instituto de Pesquisas Tecnológicas (IPT), in Brazil. Failures with two stainless steel femoral compression plates, one stainless steel femoral nail plate, one Ti-6Al-4V alloy maxillary reconstruction plate, and five Nitinol wires were investigated. The res...

background and aims. the aim of this study was to evaluate the predictability of implantation at the time of maxillary and mandibular molar extraction. materials and methods. maxillary and mandibular molars were extracted with an atraumatic technique (root separation and careful extraction with a periotome) to preserve all remaining inter-radicular bone. then, 115 tapered and straight implants ...

BACKGROUND A real-time surgical navigation system potentially increases the accuracy when used for quad-zygomatic implant placement. PURPOSE To evaluate the accuracy of a real-time surgical navigation system when used for quad zygomatic implant placement. MATERIALS AND METHODS Patients with severely atrophic maxillae were prospectively recruited. Four trajectories for implants were planned,...

On March 11, 2011, an earthquake (magnitude 9.0) devastated Japan's east coast, and the associated tsunami resulted in social and mechanical destruction. Search for the missing people is still ongoing. Surgical implants are common in the general population. Medical implants usually have lot numbers, and their forensic use is common for victim identification. This investigation was conducted mai...
