Outline of Final Research Achievements

This study suggested that PT values at the time of implantation are an important factor in evaluating the prognostic stability of anchor screws. Additionally, it was also suggested that to avoid excessively low PT values, it is important to monitor PT values during implantation, given the finding that PT values in the dislodgement group were significantly lower than those in the success group directly after implantation. Monitoring PT values in this manner may help improve the success rate of the procedure. The posterior medial area of the palate is suitable for anchor screw implantation, it is known that the palatine bone is thicker in cases in which palatal tori are present even at sites where there are no palatal tori, and we believe that such sites are suitable for anchor screw implantation.
