Ontario’s Ministry of Transportation (MTO) is responsible for the management of approximately 3000 bridges on the provincial highway network. The MTO in recent years has been evaluating developments in Bridge Management Systems in relation to its own requirements. The Ministry decided to develop an all-new system, similar in network-level functionality to modern systems developed in other count...

PURPOSE The aim of this study is to assess the influence exerted by the observer's dental specialization and compare patients' opinion with observers' opinion of the esthetics of maxillary single-tooth implants in the esthetic zone. METHODS Forty-one adult patients, who were treated with a single implant in the esthetic zone, were enrolled in this study. Eight observers (2 periodontists, 2 pr...

Componeer is an emerging esthetic solution for the treatment of discolored, fractured, or congenitally malformed teeth, which once required full-coverage restorations. Componeers combine the superior esthetic of ceramic veneers, and the bondability to tooth structure like direct composite veneers. Precontoured enamel shells with excellent color stability, no laboratory procedure, and cost effec...

No- or minimal-preparation veneers associated with enamel preservation offer predictable results in esthetic dentistry; indirect additive anterior composite restorations represent a quick, minimally invasive, inexpensive, and repairable option for a smile enhancement treatment plan. Current laboratory techniques associated with a strict clinical protocol satisfy patients' restorative and esthet...

An ideal emergence profile is vital for maintaining gingival health and developing esthetics. The ovate pontic which mimics a natural tooth gives the most appropriate emergence profile. For a successful ovate pontic restoration, an alveolar ridge of sufficient height and width is necessary to enhance the deficient ridge and to achieve an esthetic emergence profile. Interpositional graft was car...

Rehabilitation of the completely edentulous patient can present a complex treatment modality in order to fulfill the needs and desires of the patient to deliver esthetic and functional prostheses. Treatment planning and sequencing for such rehabilitation often requires a multidisciplinary approach to include restorative and surgical expertise. This clinical report will present an innovative sur...

A full-bridge converter which employs a coupled inductor to achieve zero-voltage switching of the primary switches in the entire line and load range is described. Because the coupled inductor does not appear as a series inductance in the load current path, it does not cause a loss of duty cycle or severe voltage ringing across the output rectifier. The operation and performance of the proposed ...

Ontario’s Ministry of Transportation (MTO) is responsible for the management of approximately 3000 bridges on the provincial highway network. A modern Bridge Management System is an essential tool to aid the Ministry in fulfilling its mandate to provide a safe, economical, and effective road network throughout the province. The Ministry has engaged ITX Stanley, Ltd., to provide this tool, to be...
