Photoelastic Analysis of Fixed Partial Prosthesis Crown Height and Implant Length on Distribution of Stress in Two Dental Implant Systems
The aim of this study was to evaluate by photoelastic analysis stress distribution on short and long implants of two dental implant systems with 2-unit implant-supported fixed partial prostheses of 8 mm and 13 mm heights. Sixteen photoelastic models were divided into 4 groups: I: long implant (5 × 11 mm) (Neodent), II: long implant (5 × 11 mm) (Bicon), III: short implant (5 × 6 mm) (Neodent), a...
متن کاملStress Distribution in Natural Tooth and Implant Supported Removable Partial Denture with Different Attachment Types: A Photoelastic Analysis
Background and Aim: Different attachment designs have been developed to connect implant to natural teeth in partial dentures; however, adequate studies have not been performed to determine stress distribution patterns in these designs. The present study aimed to assess stress distribution patterns in natural tooth and implant supported removable partial denture with different attachment designs...
متن کاملEffect of implant number and distribution on load transfer in implant-supported partial fixed dental prostheses for the anterior maxilla: A photoelastic stress analysis study.
STATEMENT OF PROBLEM The 4-, 3- or even 2-implant-supported partial fixed dental prosthesis (PFDP) designs have been used to rehabilitate the anterior edentulous maxilla. PURPOSE The purpose of this in vitro study was to compare the stress distribution in the supporting tissues surrounding implants placed in the anterior maxilla with 5 PFDP designs. MATERIAL AND METHODS A photoelastic model...
متن کاملEvaluating the Frequency of Implant-Supported Fixed Prosthesis Complications in Yazd Dental School in 2020
Introduction: Evaluating the frequency of complications in implant supported prosthesis such as screw loosening and porcelain fracture is important for prevention and management of these problems. The purpose of this study was to evaluate the frequency of implant-supported fixed prosthesis complications in Yazd dental school in 2020. Methods: In this descriptive cross-sectional study, the pat...
