Statement of the Problem Dental implant is one of the best choices for reconstruction of aesthetic and function. High success rate of these treatments are related to some considerations such as case selection, implant system selection and surgical methods. One-stage or two-stage surgical approaches are routine surgical methods in dental implant treatments. The minimum rate of bone loss around f...

This report describes the possibility of treating a patient affected by unilateral cleft palate and an extremely atrophied edentulous maxilla using zygomatic implants inserted in a conventional manner and maxillary implants inserted by means of a computer-assisted surgery. A cross-arch prosthesis supported by 4 maxillary and 2 zygomatic implants may be an ideal mode of prosthetic rehabilitation...

PURPOSE The aim of this article was to evaluate the survival and success of Straumann implants after immediate loading. A new method for fabricating effective definitive prostheses to immediately load implants in edentulous patients was presented. MATERIALS AND METHODS Nine patients received 4 implants each, and resin-metal prostheses were installed less than 48 hours after implant placement....

In medicine, objects that need to be removed later such as stents are commonly placed in patients, with the time of removal dependent on progress of the patient. In these cases biodegradable materials that last for a specific time may not be suitable. We propose a new class of nanostructured materials that can hold their form as long as wanted, Triggered, Nanostructured Biodegradables (TNBs), t...

BACKGROUND [corrected] Three-dimensional surgical correction of scoliosis was introduced in the 1980s by Cotrel-Dubousset. Initially only laminar and pedicular hooks, two rods (correcting and stabilizing), and transverse links joining both rods were used to correct and stabilize the spine. When implant systems had been developed and modernized, transpedicular screws in the lumbar segment were u...

INTRODUCTION The objective of this study was to compare the effectiveness of midpalatal implants with that of headgear as methods of supplementing anchorage during orthodontic treatment. This was a randomized, clinical trial at the Chesterfield and North Derbyshire Royal Hospital NHS Trust and the Charles Clifford Dental Hospital, Sheffield, United Kingdom. METHODS Fifty-one orthodontic patie...

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 ...
