SUBJECTS The study sample was derived from dental hospital patients awaiting the provision of a mandibular bilateral free-end removable partial denture (RPD). Inclusion criteria included the following: (1) maximum of 8 remaining mandibular teeth; (2) 1 to 2 anterior teeth spaces allowed, provided they were restorable using resin-bonded fixed partial dentures (FPDs); and (3) plaque score of 20% ...

Numerous problems have been reported following various therapies used to attach natural teeth to implants beneath a fixed prosthesis. This study documents the results of 843 consecutive patients treated with 1,206 natural tooth/implant-supported prostheses utilizing 3,096 screw-fixed attachments. After 3 to 14 years in function, only 9 intrusion problems were noted. All problems were associated...

Patients: A 55-year-old woman with complaints of esthetic disturbance and masticatory dysfunction visited Osaka Dental University Hospital. The remaining upper teeth showed severe degradation of the coronal dentine because of caries. Additionally, the vertical stop in the molar region was lost. In the initial treatment, an overdenture was placed for urgent improvement of the chief complaint. We...

The purpose of this study was to evaluate and compare the retention strength of five cement types commonly used in implant-retained fixed partial dentures, before and after compressive cyclic loading. In five solid abutments screwed to 5 implant analogs, 50 metal Cr-Ni alloy copings were cemented with five luting agents: resin-modified glass ionomer (RmGI), resin composite (RC), glass ionomer (...

Implants have been designed to provide edentulous patients with fixed prostheses or overdentures. Recently, implant-supported fixed partial prostheses and single crowns have become successful treatment alternatives to removable and fixed partial dentures. However, few researchers have examined "removable partial dentures on implants and natural teeth". In this article, we report two patients fi...

abstract introduction. nowadays dental implants are accepted as a successful replacement of conventional fixed and removable prosthesis which can restore esthetics in an ideal way. because of visibility of anterior teeth while smiling and speaking, the importance of esthetics in these areas is very important. in this research, the provision rate of esthetic indexes of crowns supported with swis...

Objective. Anecdotal evidence suggests that impression materials and techniques used in general dental practice for fixed partial dentures vary from those taught in dental schools. The aim of this survey was to integrate impression techniques evolved all over the years for fixed partial dentures and to know the techniques and materials which are used in the present day by the practitioners. Mat...

OBJECTIVES To evaluate the long-term longevity and patient-reported outcomes of two-unit cantilevered (CL2) and three-unit fixed-fixed (FF3) resin-bonded fixed partial dentures (RBFPDs) for the replacement of a maxillary permanent incisor. MATERIALS AND METHODS Twenty-eight subjects were randomly assigned to receive either a CL2 or FF3 RBFPD placed by one operator. Prosthesis longevity was de...

the aim of this paper is to prove some common fixed point theorems for four  mappings satisfying $(psi,varphi)$-weak contractions involving rational expressions in ordered partial metric spaces. our results extend, generalize and improve some well-known results in the literature. also, we give two examples to illustrate our results.
