Facial prosthetics has a long history that extends back to ancient man. The course of facial prosthetics has altered over time as improvement in surgical techniques and materials arrived. The need for facial prosthetics presumably also altered over time with social changes and changes in disease management. The past century has brought several remarkable changes that influenced the delivery of ...

The aim of this study was to observe the influence of prosthesis design and loading condition on the stress distributions of tooth-implant supported prostheses. Six 2D finite element models, two reference models, and four experimental models were computed to simulate different prosthesis designs. Six different loading conditions were applied to investigate the stress distributions of tooth and ...

This study aims to validate, using finite element analysis (FEA), the design concept by comparing the fatigue behavior of hip implant stems coated with composite (carbon/PEEK) and polymeric (PEEK) coating materials corresponding to different human activities: standing up, normal walking and climbing stairs under dynamic loadings to find out which of all these models have a better performance in...

OBJECTIVES Secondary tracheoesophageal (TE) puncture standardly involves placement of a catheter at time of TE fistula creation. We explore the feasibility of placement of the prosthesis at the time of TE puncture (TEP) obviating the need for a subsequent procedure to place the prosthesis. We describe the technique and evaluate the success and potential advantages. STUDY DESIGN Retrospective ...

Maxillectomy performed in acquired lesions is often very extensive or bilateral, sparing less hard and soft tissue the oral cavity. These defects need both surgical prosthetic rehabilitation. A definitive prosthesis inserted after complete healing, when patient accustomed to interim prosthesis. Definitive obturator warrants better retention stability needs a meticulous planning design for long-...

Twenty-four individuals with transtibial amputation were recruited to a randomized, crossover design study to examine stride-to-stride fluctuations of lower limb joint flexion/extension time series using the largest Lyapunov exponent (λ). Each individual wore a "more appropriate" and a "less appropriate" prosthesis design based on the subject's previous functional classification for a three wee...

Statement of the problem Many partially edentulous situations are present whereby the choice between a removable and a fixed partial denture lies within the delicate balance of a single standing abutment. This abutment is called as a pier abutment. If and when a fixed fixed prosthesis is given in such a case, the retainer over the pier abutment acts as a fulcrum and invariably leads to cement f...

Despite improvements in glenoid prosthesis design, materials and surgical techniques, complications related to the glenoid component continue to be a leading cause of failure after total shoulder arthroplasty. Although previously felt to be of little clinical significance, radiolucent lines around the glenoid prosthesis are now recognized as a sign of impending mid and long term fixation proble...
