The present study is a human, prospective, randomised controlled clinical trial conducted to explore and compare the clinical and radiological outcome of Osseodensification protocol with conventional implant site preparation protocol. The trial is in accordance with the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.
Twenty two dental implants were placed in twelve healthy individuals satisfying the inclusion and exclusion criteria were recruited for the study. A detailed, thorough medical and dental history was obtained and each patient was subjected to comprehensive clinical and radiological examination. All patients were informed about the nature of the study, the surgical procedure involved, potential benefits and risks associated with the surgical procedure and written informed consent were obtained from all patients.
All the patients received Norris implant. the implant site preparation technique being Osseodensification protocol for the test group and conventional implant site preparation protocol for the control group, eleven in each group. The clinical and radiographic parameters were recorded at baseline, immediate post implant placement, six months and twelve months postoperatively.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| osseodensification protocol | Experimental | Experimental: In the test group, osteotomy site preparation was performed using Osseodensification technique at 1100 rpm and implant was placed |
|
| conventional implant site preparation protocol | Active Comparator | Control: in the control group, osteotomy site was prepared using conventional drilling protocol at 1100 rpm and implant was placed. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| osseodensification protocol | Procedure | Local anaesthesia was administered and mucoperiosteal flap was reflected. Implant osteotomies was performed with sequential drilling with osseodensification protocol at 1100 rpm. The pilot drill was used in clockwise direction and the other sequential drills were used in counter clockwise direction under copious irrigation. Flap closure was achieved using 3-0 silk sutures to protect the implant site. |
| Measure | Description | Time Frame |
|---|---|---|
| primary implant stability | the primary implant stability was measured during implant placement using Insertion Torque Value(ITV). | immediate post implant placement |
| change from baseline in bone density | A Multislice CT was used for scanning the implant site pre operatively, just after implant placement and 1 year post implant placement to measure the change in bone density. It was performed using a tube voltage of 120 kV(kilovolt) and a tube current of 40 mA(milliampere). The occlusal plane of the patient was set perpendicular to the floor base using ear rods. The axial images was reconstructed with 0.625 mm thick slices at 0.625 mm interval and a 1.75 mm field of view(FOV) image analysis software | 1 year |
| change from baseline in crestal bone level | Digital radiographs (radiovisiograph-RVG) were standardised using radiographic paralleling technique and positioning device and custom fabricated bite-block at baseline and follow up.Mesial and distal peri-implant radiographic bone level were recorded in millimetres on the digital radiographs using Digimiser image | 1 year |
| Measure | Description | Time Frame |
|---|---|---|
| change from baseline in keratinized mucosa width | The width of keratinized mucosa was measured from the mucosal margin to the mucogingival junction at the facial surface. The mucogingival junction location was determined using a visual method (Schiller's potassium iodide solution). | 1 year |
| change from baseline in ridge width |
