Abstract
This study was conducted to correlate between the bone density estimated by cone-beam computed tomography and the stability of dental implants estimated by Osstell ISQ (resonance frequency analysis).
Ten implants were placed in 10 patients (4 females and 6 males) with missing mandibular posterior teeth. The selected patients were free from any uncontrolled systemic diseases or conditions that may complicate the surgical procedure or the healing process of the implant.
All patients were operated under local anesthesia, and a full thickness mucoperiosteal envelope flaps were raised to expose the alveolar bone. A surgical stent was fitted in the patients’ mouth to guide the drill to an exact site and angulations, followed by an osteotomy in the central part of the alveolar bone. The implant was then threaded into the bone using a Ratchet, and the cover screw was placed. The flap was then sutured around the fixtures.
Clinical follow up was performed immediately post-operative and on intervals of 3 and 6 months. Patients were evaluated for presence of pain or infection by using Visual Analogue Scale, presence of gingival inflammation assessed using the Löe and Silness Gingival Index and mobility of implant was tested according to Mickney and Koth method.
The implant stability was measured on the same follow up intervals by the resonance frequency analysis using Osstell ISQ.
Radiographic examination was carried out immediately post-operative and on intervals of 3 and 6 months using cone beam computed tomography radiographs. The bone density around the implants was measured using special software called Ondemand3D version 1.0.9.
All 10 fixtures healed well, no infection &/or implant mobility were observed on the initiation of the loading force from the prosthetic components.
The mean implant stability value was 67.3±9.14 immediately post-operatively, then increased on the 3rd month to be 72.3±3.95 and increased significantly to reach 75.2±5.33 on the 6th month.
Also the results of the present study showed that the mean bone density value was 827.96 ± 206.85 immediately post-operatively, then increased on the 3rd month to be 890.67 ± 138 & 1018.0 ±149.79 on the 6th month, there was a statistical significant increase.
The analysis of the correlation between bone density and implant stability showed that there was no statistically significant relation between them.
