Abstract
This study was conducted to evaluate the use of narrow diameter implant for replacement of lower single rooted tooth in narrow ridge.
Ten implants were placed in 10 patients (3 males and 7 males) suffering from missing lower single rooted tooth or teeth with narrow ridge. 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. Osteotomy in the central part of the alveolar bone was done. 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.
Radiographic examination was carried out immediately post-operative and on intervals of 3 and 6 months using periapical and panoramic radiographs. The bone density around the implants was measured using special software called image J program.
All 10 fixtures healed well, no infection &/or implant mobility were observed on the initiation of the loading force from the prosthetic components.

The present study showed that the mean bone density value was 79.63±8.55 immediately post-operatively, then increased on the 3rd month to be 86.35±6.48 and 92.01±5.49 on the 6th month, there was a statistical significant increase.
The present study showed that the mean marginal bone level value was 0±0 immediately post-operatively, then increased on the 3rd month to be 0.26±0.14 and 0.45±0.16 on the 6th month, there was a statistical significant increase.
So there was clear evidence of the success of the narrow-diameter dental implants in restoring edentulous single rooted tooth in the mandible. The data is statistically significant.
