Purpose: The possibility of immediate or early loading has become popular in implant dentistry. A prerequisite for the immediate or early loading of an implant prosthesis is the achievement of initial stability in the implant. Moreover, in response to clinicians' interest in verifying clinical stability to determine the optimal time point for functional loading, a non-invasive method to assess implant stability has been developed on the basis of resonance frequency analysis (RFA). The primary objective of this study was to monitor the stability of sandblasted, large-grit, and acid-etched (SLA) implants with different diameters during the early phases of healing by RFA. The secondary objective was to evaluate how the initial stability of implants varied depending on different surface modifications and other contributing factors. Methods: Thirty-five implants (25 SLA implants and 10 resorbable blasting media [RBM] implants) placed in 20 subjects were included. To measure implant stability, RFA was performed at baseline and at 1, 2, 3, 4, 6, and 10 weeks after surgery. Results: The longitudinal changes in the implant stability quotient (ISQ) values were similar for the SLA implants with different diameters and for the RBM implants. During the initial healing period, the ISQ decreased after installation and reached its lowest values at 1 week and 2 weeks, respectively. The mean ISQ values in the SLA implants were significantly higher in ${\varnothing}5.0mm$ implants than in ${\varnothing}4.0mm$ implants. Men showed a higher ISQ than women. Mandibular sites showed a higher ISQ than maxillary sites. Conclusions: All implants used in this study are suitable for immediate or early loading under appropriate indications. A wider diameter and SLA surface treatment of implants could improve the stability, if the implant is fixed with at least 30 Ncm of insertion torque.

문제 정의
However, considerable debate still exists about the optimal surface treatment method based on mechanisms of osseointegration [24,25]. The primary objective of this study was to monitor the stability of SLA implants with different diameters during the early phases of healing by RFA. The secondary objective was to evaluate how the initial stability of implants varied depending on different surface modifications and other contributing factors.
제안 방법
After attaching a magnetic peg (Smartpeg™, Osstell AB, Göteborg, Sweden) to the fixture, the Osstell® Mentor was used to measure the ISQ in both the buccal and lingual directions, and the mean of these measurements was then calculated (Figure 2).
This method was used to evaluate initial stability at the time of implantation and at 1, 2, 3, 4, 6, and 10 weeks postoperatively. Changes in the mean ISQ and the magnitude of ISQ changes were analyzed according to several parameters (surface treatment method, implant diameter, dental arch, and sex) in order to examine their correlations with implant stability.
Intergroup comparisons were performed for various parameters using the ISQ values measured at each time point, including the ISQ value immediately after implantation. The Student's t-test was used to verify the statistical significance of intergroup differences by surface treatment, dental arch, and sex.

대상 데이터
The implant fixtures were the Dio® UF HAS (Dio Co. Ltd., Busan, Korea) for the SLA implants, and the Osstem® USII plus system (Osstem Implant Co. Ltd., Seoul, Korea) for the RBM implants.
The subjects in this study were patients who visited the Department of Periodontology, Pusan National University Dental Hospital and underwent dental implant surgery between March 2013 and August 2014. Preoperative clinical and radiological examinations were used to select patients suitable for the study.
There were 20 subjects in total (male, 10; female, 10), with an average age of 54.95±24.95 years, and a total of 35 implants (SLA, 25; RBM, 10).

The Student's t-test was used to verify the statistical significance of intergroup differences by surface treatment, dental arch, and sex. One-way analysis of variance was performed to analyze differences by implant diameter. The Scheffé's test was chosen for post-hoc analysis.

성능/효과
The stability dip occurred at week 1 for the SLA group and at week 2 for the RBM group. After the stability dip, both groups showed a gradual increase in the ISQ, and in weeks 4 and 6, the ISQ of the SLA group was significantly higher than that of the RBM group. The time at which the ISQ recovered to a level higher than week 0 was at week 2 for the SLA group and week 10 for the RBM group (Table 2).
Therefore, both types of implants can be candidates for immediate or early loading, with their initial stability confirmed via the ISQ. However, based on the observations that the ISQ in the SLA implants was significantly higher than in the RBM implants at week 4 and week 6, the fact that the stability dip was 1 week earlier in the SLA implants, and the recovery to the initial ISQ was faster in the SLA implants, it can be concluded that the SLA surface is therefore more suitable for immediate loading (before 1 week).
In implants where an implantation torque of at least 30 Ncm was confirmed, larger implant diameter and SLA surface treatment showed a positive effect on initial implant stability.
후속연구
This tendency suggests that SLA surface treatment has a positive effect on initial implant stability, particularly after the stability dip, and that this could offset the effects of diameter. However, this conclusion requires additional research with a more appropriate design, including a control group with the same diameter.
