PURPOSE This article describes the surgical technique for implant treatment in severely resorbed edentulous maxillae without any alveolar reconstruction before or combined with implant placement. PATIENTS AND MATERIAL Fifteen patients with severely resorbed edentulous maxillae were treated with osseointegrated implants and fixed dental prostheses. All patients were initially considered to be ...

Sanguinivorous Naobranchia variabilis prefer the first gill arch, external hemibranch and anterior end of the gill arch. The smallest N. variabilis observed attached to fish by a thin filament which connects fused tips of second maxillae to a 'plug' inserted into the gill tissue. Second maxillae enlarge to encircle and increasingly compress the gill filament, which results in a thin layer of ep...

PURPOSE The aim of this study was to analyze and compare the survival rates of endosseous implants placed in the edentulous maxillae of patients in whom bone augmentation was undertaken prior to or in conjunction with implant placement with survival rates in patients who did not undergo bone augmentation. MATERIALS AND METHODS This study included 2 retrospective patient groups: the graft grou...

UNLABELLED Growth factors and growth stimulating genes are main signaling molecules for growth and development in ante- and postnatal period involved in cellular proliferation, differentiation and morphogenesis of tissues and organs during embryogenesis, postnatal growth and adulthood. The aim of this study was to evaluate TGF-beta (transforming growth factor-beta), BMP2/4 (bone morphogenetic p...

PURPOSE To evaluate the use of the buccal fat pad flap (BFPF) technique as an option to prevent complications in the treatment of patients with atrophic maxillae rehabilitated after complex zygomatic implant surgery. MATERIALS AND METHODS A retrospective study was made of completely edentulous patients submitted to zygomatic implant surgery between May 2005 and November 2007. Patients with se...

The evolution of features that enhance an organism's performance in one activity can adversely affect its performance in another. We used an experimental approach to document a trade-off associated with the evolution of the long hook at the tip of the bill of birds belonging to the genus Diglossa (flowerpiercers). In Diglossa, the more derived flower-robbing nectarivorous species have maxillae ...

The present study is a cladistic analysis of morphological characters focusing on the file of the mandible, the apices of the maxillae, the rupturing device on the maxillae, the internal structures of the mouthparts, and the external morphology of the labial segments as well as the distribution of labial sensilla in true water bugs (Hemiptera: Heteroptera, infraorder Nepomorpha). The study is b...

BACKGROUND There is an increasing number of scientific evidence supporting the clinical use of short dental implants. However, few studies have evaluated the long-term outcomes of immediate loading protocols in short implants. This study aims to evaluate immediate loading of short dental implants in the posterior regions of the maxillae. MATERIALS AND METHODS Patients having short implants in...

BACKGROUND The existing approaches to the treatment of the atrophic maxilla are difficult and involve an element of risk. PURPOSE The aim of the present study was to establish a new surgical/prosthetic protocol for the treatment of extremely atrophic maxillae using four zygomatic implants (ZIs) in an immediate loading system. MATERIALS AND METHODS Twelve patients were treated with the surgi...
