Abstract EN
Statement of the Problem.
Fit of prosthodontic frameworks is linked to the lifetime survival of dental implants and maintenance of surrounding bone.
Purpose.
The purpose of this study was to evaluate and compare the precision of fit of milled one-piece Titanium fixed complete denture frameworks to that of conventional cast frameworks.
Material and Methods.
Fifteen casts fabricated from a single edentulous CAD/CAM surgical guide were separated in two groups and resin patterns simulating the framework for a fixed complete denture developed.
Five casts were sent to dental laboratories to invest, cast in a Palladium-Gold alloy and fit the framework.
Ten casts had the resin pattern scanned for fabrication of milled bars in Titanium.
Using measuring software, positions of implant replicas in the definitive model were recorded.
The three dimensional spatial orientation of each implant replica was matched to the implant replica.
Results.
Results demonstrated the mean vertical gap of the Cast framework was 0.021 (+0.004) mm and 0.012 (0.002) mm determined by fixed and unfixed best-fit matching coordinate system.
For Titanium frameworks they were 0.0037 (+0.0028) mm and 0.0024 (+0.0005) mm, respectively.
Conclusions.
Milled one-piece Titanium fixed complete denture frameworks provided a more accurate precision of fit then traditional cast frameworks.
