offer many practical advantages over conventional complete dentures and removable partial dentures. These include decreased bone resorption; reduced or eliminated prosthesis movement; better esthetics; improved tooth position; better occlusion, including improved occlusal load direction, increased occlusal function and maintenance of the occlusal vertical dimension. In addition, implantImplant-...

Objectives: This study was performed to compare implant locators versus customized mandibular implant-retained overdentures considering patient satisfaction and prosthesis maintenance. Materials methods: 12 completely edentulous patients from the prosthodontic department-Cairo university outpatient clinic were selected according specific inclusion criteria. The then allocated randomly into two ...

OBJECTIVE There is no definitive study comparing stress distribution around two versus three implants in implant-retained overdentures with different cantilever length. The purpose of this finite element study was to evaluate stress pattern around the implants of the 2 or 3 implant- supported mandibular overdenture with different cantilevered length. MATERIALS AND METHODS The models used in t...

OBJECTIVES The objective of this clinical study was to evaluate the prosthetic complications of patients with 2 to 4 implants splinted with a round bar or with 2 to 4 unsplinted implants with ball attachments during the follow-up period. METHODS A total of 26 patients were included in this study. Patients were randomly provided with a round bar or with ball attachments that were used to retai...

Open-field aluminum-nickle-cobalt magnets have been used in prosthodontics for many years, but success has been limited because these magnets are susceptible to corrosion by the saliva and because their retentive force is weak relative to the initial retention offered by mechanical attachments. More recently, magnets have been made from alloys of the rare earth elements samarium and neodymium, ...

AIM This study aimed to compare the stresses generated by using two or four root form dental implants supporting mandibular overdentures that were retained with ball and locator attachments. METHODS Under ANSYS environment, four 3D finite element models were prepared. These models simulated complete overdentures supported by two or four implants with either ball or locator attachments as a co...

Rehabilitation of the edentulous jaw can be achieved with various treatment modalities. Removable implant-supported overdentures can provide a comfortable, aesthetic and functional option even in cases in which only a limited number of implants can be used. Since the number of patients desiring an alternative to complete dentures is on the rise, this treatment option is becoming a frequent choi...

The aim of this non-randomized controlled clinical trial was to evaluate the oral health-related quality of life and masticatory efficiency of patients rehabilitated with mandibular two-implant overdentures with immediate loading or conventional dentures. Fifty completely edentulous patients wearing bimaxillary conventional dentures, for at least one year, were recruited. The patients were then...

Jefferson Ricardo Pereira Professor at the Specialization course in Dental Prosthesis, Cruzeiro do Sul University. Abstract / Overdenture is deined as a completely or partially removable denture that covers or is supported by one or more remaining natural teeth, roots and / or dental implants. This study aims to examine the masticatory eficiency and patient acceptability of overdentures compare...
