Assessment of prosthetic complications of customized and electrical welded frameworks in maxillary implant fixed detachable prosthesis (split mouth study)

Abstract

This study was conducted to asses prosthetic complications, passive fit, chair side visits numbers and duration, cost and cost effectiveness of customized and electrical welded frameworks in maxillary implant fixed detachable prosthesis. Materials and Methods: This split mouth study was performed on six completely edentulous patients received maxillary fixed detachable prosthesis, where Group I: customized framework while Group II: electric welded framework. During prosthetic construction period for both frameworks, passive fit was done using gone screw test Assessments of prosthetic complications were evaluated 3 and 6 months later. Numbers and duration of visits, total cost and cost effectiveness were calculated Results: Comparison between both groups revealed insignificant difference regarding all prosthetic complications. after 3 months and 6 months. The Evaluation of the passive fit revealed that in customized framework was significantly higher than electric welded group in yes, while was significantly lower in no. In group I C/E ratio (93.5) was higher than group II (85.7), as the total cost in group I was (9350), while in group II was (7150). In number of needed visits, group I (6.83 ± 0.75) was significantly higher than group II (3.16 ±0.41) as P <0.05. In duration of needed visits, group I (330 ± 11.3) was significantly higher than group II (150 ±8.5) Conclusion: Maxillary fixed detachable prosthesis supported by customized or electric welded framework show no difference regarding the prosthetic complication while the electric welded framework shows highly passive fit when compared to the customized one. The cost, cost effectiveness, numbers of visits are lower and visits duration is shorter in electric welded framework when compared to the customized one.
