Abstract
This study was conducted to compare and measure the implant stability quotient (ISQ) values of immediately and early loaded dental implants in the posterior mandible.
The study included fourteen patients of both genders. They were selected from the Outpatient Clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Alexandria University. Patients age ranged between 27-40 years, with an average age of 34.5 ± 0.12 years.
The patients were divided into two groups. In group I, the provisional restorations were delivered immediately post-insertion (immediate loading), while in group II the provisional restorations were delivered one month post-insertion (early loading).
Patients were evaluated clinically immediately post-operative and on the 1st, 3rd and 6th months after surgery for the following:
1- The presence of pain or any post-operative complications.
2- Measuring the Probing depth.
3- Assessing the degree of gingivitis.
4- Measuring the implant stability quotient values with the Resonance frequency analysis.
Also, radiographic follow-up was performed to assess the level of bone height and density around dental implants using Image J program.
Research has shown the following results
It was recorded that during the study period all cases suffered the minimum level of pain and swelling, and did not register any kind of movement of the implants or gingival inflammation or infection.
During the study period there was a decrease in the height of the bone in both groups after one month then the marginal bone level increased throughout the follow up period, while the density of the bone around the implant increased throughout the follow up period.
During the study period there was a decrease in both groups in the implant stability after one month. The decrease was more in the early group immediately and after one month. The values increased in both groups after 3 months, and 6 months. There was a statistical significance of mean implant stability increase in the early group.
In both groups, the implant stability quotient (ISQ) decreased after one month. The values were 66.57±6.24 and 59.86±11.42 respectively. The decrease in implant stability after one month between both groups was not statistically significant. (p=0.197) In both groups, the implant stability quotient (ISQ) increased after 3rd month. The increase in the early group was higher than the immediate group. In the immediate group 71.29±2.14, and in the early group 75.86±3.18. The increase in implant stability quotient after 3rd month between the studied groups was statistically significant. (p=0.008) In both groups, the implant stability quotient (ISQ) increased after 6th months. The increase in the early group was higher than the immediate group. In the immediate group 71.29±4.61, and in the early group 77.71±1.60. The increase in implant stability quotient after 6th months between the studied groups was statistically significant. (p=0.009)
Therefore, the results of the present clinical study demonstrated superior implant stability when implants were loaded one-month following implant insertion.
