 note = {It is necessary to establish objective criteria for determining the optimal time to connect the super structure to the implant. Several studies have examined the usefulness of the Periotest^[○!R] for determining this timing. However, few investigators have studied the usefulness of this test, based on analysis of the reproducibility of the periotest^[○!R] values (PTV). We are studying the clinical applicability of the Periotest for POI 2-Piece implants,^[○!R] using a post specially designed for this test. The results obtained were as follows. 1. It seems possible that the Periotest^[○!R] allows surgeons to predict the prognosis of implants based on an analysis of the time course of PTV for the same type of implants and to determine the optimal time to connect the super structure to the implant. In our department, a PTV below +9 is regarded as indicating the optimal timing of super structure connection. 2. It seems possible that the Periotest^[○!R] can be used in judging whether or not a 2-piece implant^[○!R] should be connected to natural teeth or that the optimal post can be selected based on an analysis of the PTV of natural teeth. 3. The Periotest^[○!R] seems to allow surgeons to check that an implant has been bicortically inserted. This check seems to be most useful when it is done immediately after implant insertion. In practice, however, the use of the Periotest^[○!R] for this check immediately after implant insertion is not possible because the accuracy of drilling differs among different surgeons. The Periotest^[○!R] may therefore be used in making such a check at the time of super structure application and in predicting long-term prognosis after super structure application. Although the Periotest^[○!R] seems to be clinically applicable to these purposes, it seems indispensable to pay attention to the reproducibility of the PTV and to standardize the conditions for PTV measurement., application/pdf},
