简要总结
The aim of this study is to compare two different methods for occlusal analysis of implant - supported prosthesis (T-scan and conventional method with articulating papers) regarding the stresses transmitted to the implants.
详细描述
Four implants will be inserted, two implants in canine regions and two implants in lower second premolar regions.
After 3 months, two identical overdentures will be constructed for the patient on implants.
The occlusion of each one of the two identical prostheses will be adjusted intraorally but according to different occlusal analysis:
- Group (A) : occlusal adjustments for the overdenture will be done according to articulating paper analysis.
- Group (B) :- occlusal adjustments for the overdenture will be done according to T-scan analysis.
The two prostheses will be retained on dummy implants on acrylic cast and will be loaded under chewing simulator.
