Abstract
POI 2piece Implant® which had first been started to apply clinically in 1991 has entailed a satisfactory result. This author et al. have examined the case of failed case from the clinical viewpoint and have reported the results of them this time.
The patient was a women of 67 years old who was introduced to our clinic from the dentistry of other hospital for making prosthesis using the implant. Using angle post for super structure because the angulated Implant placement was applied for implantation, fixed prosthesis using key-and-keyway was set. As the procedure of treatment, we directed her doctor to have the implants of 36 and 37 removed and have the residual root extracted, followed by making bilateral free-end dentures. We also directed her doctor that she come to our clinic for diagnosis then. Found her teeth of 34 still existing as the residual root looking panorama X-ray photograph.upon diagnosis of her on August 27, I extracted the teeth. After removing the anterior bridge, I repaired the bilateral free-end denture. Having loaded the fixture of 31 and 45 with attachment male each and then made temporary overlay denture on the same day. I abandoned the trial to apply the fixture of 43 because of parallelism and also 37 because of impossibility of long term stability. After the mucosa have healed, I have newly made the overlay denture. Result
1) Multiapplication of the angulated Implant placement will make the process of prothesis complicate, resulting in making difficult the control of post prothesis.
2) The ball attachment has been found effective for promoting the temporary prothesis on the same day.
3) I think it would necessary for us to communicate well each other as well as to communicate with patient well in treatment of them.
