The percentage of completely and partially edentulous patients and their prosthetic treatment at the Department of Substitutive Dental Sciences (SDS), College of Dentistry, University of Dammam, were investigated. Panoramic radiographs and medical records of adult patients (n = 479, mean age 45.9 years, and range 25-96 years) treated in 2011-2014 were examined. 6% of the patients were completel...

Immediate loading of titanium implants intended to become osseointegrated has peaked the interest of many clinicians and researchers. The evolution from the traditional 2-stage protocol, originally developed by Per Ingvar Brånemark, has provided exceptionally excellent results over the past two decades. However, patients’ desires and needs have also traditionally encouraged clinicians and resea...

The oral mucosa of the edentulous ridges presents many morphological macroscopic and microscopic variations, from one area of the edentulous ridge to another, as well as from one patient to another. Because the mobile prosthetic treatment realizes a direct contact between the dental prosthesis and the mucosa of the denture supporting structures and of the peripheral structures, the prosthetic s...

Dental implants in partially edentulous patients are a predictable therapeutic option. However, using tooth-to-implant restorations to rehabilitate partially edentulous patients involves highly complex biomechanical aspects. This type of prosthesis utilizes different kinds of support that react distinctly to the functional forces developed in the oral cavity. In some cases, a tooth-to-implant r...

Cell-mediated immunity in humans to antigens derived from oral plaque bacteria was investigated by using the lymphocyte blastogenesis assay. Subjects with varying severities of periodontal disease including normal, gingivitis, periodontitis, and edentulous were compared. Mononuclear leukocytes were separated from peripheral blood and cultured with antigens prepared by sonication of Actinomyces ...

Clinical studies have revealed that the main objective of implants in the edentulous jaw is to provide support for fixed prostheses or to stabilize complete dentures. Various attachment systems were developed for universal use in partially and completely edentulous patients such as clasps, cone-shape telescope copings, magnets, bar systems, locators. The aim of this case report is to present th...

dentures continues to be a frequently applied therapy option. Yet, populating the edentulous jaw with denture teeth to achieve a functional and esthetic rehabilitation poses a tough challenge to the treatment team. Biomechanical, physiological and geriatric concerns must be considered. True-to-nature replication of teeth and soft oral tissues also plays a key part. The objective is to give pati...

PURPOSE This study compared polyvinylsiloxane with polyether in handling dental impressions. MATERIALS AND METHODS Each participant (N = 39) made four impressions, each a combination of pickup and reseating techniques with polyether or polyvinylsiloxane, of one implant cast representing a specific clinical situation (tooth gaps, limited residual dentition, or edentulous jaw). Handling of impr...

PURPOSE The aim of this study was to systematically review the evidence for immediate implant loading in partially edentulous patients with extended edentulous sites and evaluate potential treatment modifiers. MATERIALS AND METHODS An electronic search was performed in Medline, Embase, and Central to identify studies investigating the outcome of implants subjected to immediate loading (IL) (l...

Background: A minimum of four implants should be used in edentulous maxillae to anchor a dental prosthesis. A wide anterior/posterior distribution of the implants is advantageous. Besides bone grafting, short or tilted implants are used to achieve this in atrophic edentulous maxillae. The implants define a polygon that should be as large as possible. This study investigated the differences in t...
