The literature contains numerous observations on the significance of systemic disorders as contraindications to dental endosseous implant treatment, but the justification for these statements is often apparently allegorical. Although implants are increasingly used in healthy patients, their appropriateness in medically compromised patients is less(More)
PURPOSE An international Delphi study was undertaken to determine by consensus an agreed approach to the management of children with dental manifestations of ectodermal dysplasia, including the use of dental implants. This was done using a questionnaire developed by an interdisciplinary team. MATERIALS AND METHODS The Delphi study questionnaire was built(More)
AIMS The ability to predict the morbidity of retained deciduous teeth with no permanent successors, a characteristic of hypodontia, would be of considerable value in treatment planning, but is hampered by lack of data. METHODS This problem was studied using 356 orthopantomogram radiographs (OPGs) from the records of 249 patients who had attended a(More)
A survey is presented of the complaints and findings in a group of 451 patients referred to a multidisciplinary clinic for the management of hypodontia. The most common complaints were missing teeth, spacing in the dental arches, and poor appearance. The majority of patients were referred by their dental practitioners, and more than half were over 12 years(More)
STATEMENT OF PROBLEM Forces may arise in association with the use of implant stabilized mandibular fixed partial dentures as a result of functional jaw deformation, yet the phenomenon has received little attention and is rarely included as a variable when investigating implant biomechanics. PURPOSE This in vitro investigation tested the hypothesis that(More)
Loss of osseointegration of implant fixtures and mechanical failure of superstructures have been attributed to failure to achieve a passive fit between the superstructure and the transmucosal abutment (TMA). The fit of five mandibular superstructures, fabricated on Nobel Biocare implants, was investigated in vivo, using a polyvinyl siloxane impression(More)
BACKGROUND The long-term success rates achieved in dental implantology suggest that flexibility might well exist within the various implant systems to a degree that an altered protocol (ie, one-stage surgery and immediate or early loading) can be performed under controlled conditions. However, before variations of the protocol can be considered for general(More)
A study was undertaken to compare the effectiveness of an information leaflet with a multimedia program in informing potential implant patients attending a dental hospital. The results show that both methods of presenting information are effective in informing patients; however, where the information to be presented is visual in nature, a multimedia(More)
Experiments were conducted to investigate the pressures that are exerted on drills during the preparation of bone. Twenty operators used six different types of drills at high and low speeds to prepare standardized holes and slots in animal bone. The peak vertical forces exerted varied between 5.98 and 24.32 newtons (x = 12.45 newtons). The mean vertical(More)
