Background: The aim of this study was to evaluate the role AT1 and AT2 receptors in a periodontal inflammation experimental model. Methods: Periodontal induced by LPS/Porphyromonas gingivalis. Maxillae, femur, vertebra were scanned using Micro-CT. Maxillae analyzed histopathologically, immunohistochemically, RT-PCR. Results: showed decreased BMD H compared with WT (p < 0.05). femur increased...

Background: A minimum of four implants should be used in edentulous maxillae to anchor a dental prosthesis. A wide anterior/posterior distribution of the implants is advantageous. Besides bone grafting, short or tilted implants are used to achieve this in atrophic edentulous maxillae. The implants define a polygon that should be as large as possible. This study investigated the differences in t...

Bisphosphonate-related osteonecrosis of the maxillae may be an important complication of long-term osteoporosis treatment. The possibility of osteonecrosis of the maxillae in patients exposed to nitrogenated bisphosphonates was first described in 2003. Since then, case reports and retrospective studies have demonstrated higher percentages of occurrence of osteonecrosis in patients who have used...

The purpose of this retrospective study was to determine the outcome of Brånemark System TiUnite® implants (Nobel Biocare/Sweden), and to identify the risk factors associated with implant failure. A total of 151 patients (83 maxillae and 91 mandibles) received 619 implants from July 2003 until May 2010. The patients included 86 males and 65 females, with a median age of 51.6 years and an ag...

Neurofibroma is a benign tumour composed from Schwann cells. Localization in sinus maxillea is very rare. Authors presenting case which was treatment in Maxillo-Facial Surgery Clinic in Wrocław.

A survey was undertaken to analyze osseointegrated implants placed in irradiated maxillae and mandibles. It was found that nine centers in Japan and two centers in the United States had placed 228 implants in 44 patients. Of 228 implants, 59 were placed in the maxilla, 169 in the mandible. Three of 169 implants placed in irradiated mandibles were removed; 17 of 59 were removed from maxillae. On...

The feeding of 6 copepods (Calanus finmarchicus, Acartia tonsa, Centropages hamatus, C . typicus, Labidocera aestiua, and Tortanus discaudatus) was examined with 3 different foods-a ) diatoms ( Thalassiosira flt~uiatilis) alone, b ) diatoms plus Artemia nauplii, and c ) Artemia alone-and compared with the structure of their mouth-parts. Calanus finmarchicus is predominantly an herbivore, but in...

of the right ear, cutting into the maxillae to a depth of about two inches. The hard palate was not injured. There was actually a false joint, the lower portion being moveable on the upper segment, as if the superior maxillae were in two pieces, which, of course, was the case. The man while asleep was struck with the <f kussa," but the blow woke him, and he got up and struggled with his assaila...
