The aim of this study was to evaluate time serial change of the TPTC(Tightness of Proximal Tooth Contact) between the implant prosthesis and natural tooth at rest state. Thirty-one patients(19 males and 12 females; mean age, 48.2 years) restored with a total 31 single-implant crowns in the left maxillary for 13 single-implant and left mandibular second molars for 18 single-implant crowns, respectively were selected. The TPTC was checked directly after delivery, 1 month after delivery and 6 months after delivery of prothesis at rest state. The TPTC decreased significantly as time goes by both maxilla(p<.01) and mandible(p<.05). The TPTC between the implant prosthesis and natural tooth decreased as time goes by after fixed implant prothesis placement.
