Up to date, zygomatic implants (ZIs) have been considered a predictable treatment modality for cases of atrophic maxilla. In some severe cases with severe vertical and/or horizontal bone resorption in the anterior maxilla, the placement of standard implants in the anterior area represents a challenge. In these arduous scenarios, performance of a zygomatic "quad-approach" might be advocated. Nev...

Aim To test the hypothesis that use of rhBMP2 in established defects requires additional growth factors such as rhVEGF to accomplish effective bone repair. Materials and Methods Horizontal/vertical 2 cm length 1 height were created bilaterally alveolar crest maxillae 18 minipigs together with extraction all premolar teeth one molar tooth on both sides. After 3 months healing, augmented 0.5 g pa...

The aim of this paper is to present the post mortem dental evidence and dental health of the victims interred during 1999 in five grave pits at Batajnica near Belgrade. The investigated sample comprised 32 individuals with only maxillae preserved, 80 with mandible, and 260 individuals with both jaws. We have found high degree of enamel hypoplasia (25.89%), frequent signs of the severe forms of ...

Acquisition of the lower jaw (mandible) was evolutionarily important for jawed vertebrates. In humans, syndromic craniofacial malformations often accompany jaw anomalies. The basic helix-loop-helix transcription factor Hand2, which is conserved among jawed vertebrates, is expressed in the neural crest in the mandibular process but not in the maxillary process of the first branchial arch. Here, ...

Two new species of the genus Cardiodectes Wilson, 1917 (Siphonostonatoida: Pennellidae) are described based on females from gobiid fishes (Actinopterygii: Perciformes) in coastal waters of the Pacific Ocean. Both new species belong to the 'rubosus' group sharing a trunk without an abdomen. Cardiodectes bellwoodi n. sp. parasitizes Istigobius nigroocellatus (Günther) in Australian waters and dif...

Objective: To determine the range and prevalence of pathological conditions and demonstration of significant anatomical structures in the maxillary sinuses using the cone beam computerized tomographic (CBCT) scan. Methodology: Case series of 60 CBCT scans of the maxillae. Results: Forty (67%) of the scans were of female patients while the rest (20, 33%) were of males. Remarkably, the majority o...

AIM The purpose of the present study was to describe the posteroanterior cephalometric norm values from Hispanic Americans Peruvian non adults patients between years 2009 to 2010, identify possible differences between sexes and compare our results with similar studies in the literature. MATERIAL AND METHODS Data from posteroanterior cephalograms from 318 patients (177 females and 141 males) b...

OBJECTIVE To investigate the effects of systemically given propolis on the expanded premaxillary suture in a rat study model. MATERIALS AND METHODS The 24 rats were randomly divided into three groups-only expansion (OE), expansion plus propolis (PRO), and nonexpansion (control) groups. After the 5-day expansion period was completed, the OE and PRO groups underwent 12 days of mechanical retent...

INTRODUCTION Brown tumors are rare focal giant-cell lesions that arise as a direct result of the effect of parathyroid hormone on bone tissue in some patients with hyperparathyroidism. Brown tumors can affect the mandible, maxilla, clavicle, ribs, and pelvic bones. Therefore, diagnosis requires a systemic investigation for lesion differentiation. CASE PRESENTATION We present a 42-year-old Gre...

This study compared the cephalometric features of a group of one hundred children aged from six to sixteen years suffering from chronic perennial allergic rhinitis of differing grades of severity with those of 99 control subjects of similar age. Both samples were drawn from a Children's Hospital which has a large population of patients with chronic perennial allergic rhinitis attending the Alle...
