Abstract
Purpose: The purpose of study was to analyze the initial stability change of N company A implant.
Materials and Methods: A total of 32 implant were placed in 4 mongrel dogs. Implant were divided into 2 groups following to manufacturer. Group 1 is consisted of 16 of A implant (N co., Seoul, Korea), and Group 2 is consisted of 16 of B implant (C co., Seoul, Korea). After implant placement, ITV (insertion torque value), ISQ (implant stability quotient), PTV (periotest value) were measured immediately, 2 weeks, 4 weeks and 16 weeks of healing period. With the animal’s sacrifice 12 weeks after implant installation and histomorphometric analyses were performed. Statistical analyses were performed using SPSS for window (ver.20.0 SPSS Inc.). Statistical differences were considered significant at p＜0.05.
Results: There was significant difference of ITV, ISQ, PTV between A implant and B implant at all of period (p＜0.05). There was no significant difference of initial stability change of A implant (p＞0.05). The percentage of direct bone-to-implant contact (BIC) and bone area ratio (BA) showed statistical significant between group 1 and 2 at 12 weeks (p＜0.05).
Conclusions: These result indicate that A implant does not have stability dip. In conclusion, A implant allows immediate or early loading implant protocol.
