lh e purpose of the protrusive jaw relation record is to adjust the condylar elements of the articulator so that they will present inclinations which are, as nearly as possible, similar or equivalent to those in the temporomandibular articulation. Most adjustable articulators for complete denture procedures will receive a protrusive interocclusal relation record, and the horizontal condylar inc...

PURPOSE To report on the clinical outcome of 150 extrasinus zygomatic implants placed lateral to the maxillary sinus and combined with conventional implants in the anterior maxilla for the implant-supported rehabilitation of the edentulous maxilla. MATERIALS AND METHODS All patients included in this study presented with completely or partially edentulous maxillae with any remaining teeth indi...

Sexually selected male weaponry is widespread in nature. Despite being model systems for the study of male aggression in Western science and for cricket fights in Chinese culture, field crickets (Orthoptera, Gryllidae, Gryllinae) are not known to possess sexually dimorphic weaponry. In a wild population of the fall field cricket, Gryllus pennsylvanicus, we report sexual dimorphism in head size ...

Sangiran (Solo Basin, Central Java, Indonesia) is the singular Homo erectus fossil locale for Early Pleistocene Southeast Asia. Sangiran is the source for more than 80 specimens in deposits with (40)Ar/(39)Ar ages of 1.51-0.9 Ma. In April 2001, we recovered a H. erectus left maxilla fragment (preserving P(3)- M(2)) from the Sangiran site of Bapang. The find spot lies at the base of the Bapang F...

PURPOSE The purposes of this study were to investigate the internal structure of the edentulous zygomatic bone, which provides anchorage for the zygomatic fixture, using micro-computed tomography, and to examine the relation between the internal structure of the edentulous zygomatic bone and the zygomaticus fixture. MATERIALS AND METHODS Twenty-eight zygomatic bones of edentulous maxillae fro...

The aim of this study was to evaluate the clinical function and long-term prognosis of overdentures retained by a small number of implants in the maxilla and mandible using one of two different attachment systems. Included in the study were all patients referred to specialty clinics in Jönköping and Linköping, Sweden, during the treatment period who needed an overdenture and could be provided w...

A primary intraosseous carcinoma (PIOC) is a squamous cell carcinoma arising within the  jawbone andshould be differentiated from a malignant ameloblastoma.  It  is not due to arising from an odontogenic cyst or tumor. The possibility of the lesion being  a metastasis fromanotherprimary site should be considered, and excluded by a careful history and examination. The diagnosis of a PIOC is ra...

Three Geophilus impressus C. L. Koch, 1847 specimens collected in Băneasa Forest, Southern Romania are described and illustrated. The sampled population represents a new lower limit for the leg-bearing segment number of this species morphological differences to previous descriptions that cast doubt on reliability using size- age-dependent features maxillae last-leg bearing when separating it fr...
