Abstract
Temporary restoration is useful to decide prosthodontic method. If the strength of the temporary restoration is so higher that is tolerable in services for long period, fixed prosthesis is better than removable one in regard to an appearance and a feeling.
The purpose of this study is to confirm experimentally the strength of the provisional fixed prostheses which are composed of acrylic resin teeth and adhesive resin. The compressive force need to replace the pontic which is directly bonded the extracted human teeth was measured in vitro.
Approximate 30 kg was needed to break the provisional adhesive pontic, whereas about 120 kg was needed to the posterior pontic reinforced with wire.
These results suggest that this method is useful as one of the provisional treatments.
