Comparative Evaluation of Osseodensification Versus Conventional Implant Site

Not Applicable

Completed

• Conditions: Bone Density; Implant Stability

• Registration Number: NCT04189718
• Lead Sponsor: Krishnadevaraya College of Dental Sciences & Hospital

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
change from baseline in crestal bone level	1 year	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
primary implant stability	immediate post implant placement	the primary implant stability was measured during implant placement using Insertion Torque Value(ITV).
change from baseline in bone density	1 year	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

Secondary Outcome Measures

Name	Time	Method
change from baseline in keratinized mucosa width	1 year	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).
change from baseline in ridge width	1 year	Soft tissue and hard tissue labio-lingual ridge width was measured at baseline, immediate post implant placement, 6 months and 1 year after implant placement using ridge mapping calipers/Multislice CT.
Patient reported pain evaluation (Visual Analog Scale)	1 year	patient were asked to report the pain after the procedure in terms of visual analog scale (VAS) score in a rating between 1 to 10. There are 5-point verbal descriptive scale with an interval of 2("nil," "mild," "moderate," "severe," and "very severe") Patients were asked to rate their pain in a score between 1-10
