- Registration Number
- NCT06034067
- Brief Summary
A total of 34 participants, who require replacement of an anterior or posterior single tooth with dental implant, will be randomly allocated to two equal sized groups. In the control group, the osteotomy site preparation will be prepared by using conventional surgical drills, while the test group site preparation will involve the use of Densah™ Burs (Versah Co., LLC., USA) as per the osseodensification protocol. In addition to evaluating implant stability, the trial will also report on implant and patient outcomes at various time points.
- Detailed Description
Osseodensification technique has demonstrated increased primary stability and increased bone mineral density around the osteotomy site. The implants placed into osseous densification osteotomies have shown significant increase in insertion and removal torque values. This technique also burnishes bone along the inner layer of the osteotomy site and create a condensed layer of autografted bone along the periphery and apex of the implant. This would, in turn, increase the bone-implant contact enhancing the insertion torque values, and thus, primary implant stability. This new technique has not only shown increased primary implant stability when compared with conventional drilling, but also, shown to have similar clinical safety to conventional methods of osteotomy site preparation. Although osseodensification has been reported to enhance the clinical outcomes of implants by increasing primary stability, its long-term effects on implant stability measurements and implant survival rates are still not clear. The purpose of the present randomized controlled trial is to evaluate the stability of implants placed in sites prepared with either conventional drilling or osseodensification and report on implant and patient outcomes at various time points.
Objectives:
The aims of the randomized controlled trial are:
* To evaluate implant stability as measured by implant stability quotient (ISQ).
* To evaluate the clinical, radiographic outcomes and implant survival rates.
* To evaluate the need for additional bone augmentation at the time of implant placement.
* To evaluate changes in peri-implant marginal bone level.
* To evaluate bone quality as estimated by clinicians during osteotomy preparation.
* To evaluate biological and technical complications during the follow-up period.
* To evaluate patient reported outcomes.

Group Intervention Description Standard (control) group Standardized osteotomy preparation Implant site preparation will be completed using conventional drilling protocol technique where standardized drills provided by Straumann (Straumann®, Institute Straumann AG, Basel, Switzerland)) will be used as per manufacturer's instructions. Osseodensification (test) group Osseodensification osteotomy preparation Implant site preparation will be completed using osseodensification technique where tapered multifluted burs (Densah Burs; Versah, MI, USA) will be used as per manufacturer's instructions.
- Primary Outcome Measures
Name Time Method Changes in Implant stability quotient (ISQ values) using resonance frequency analysis Upto 36 months Resonance frequency analysis (RFA) will be used to determine stability (the level of osseointegration) in dental implants. The stability will be presented as an implant stability quotient (ISQ) value. The measurements will be recorded at time of implant placement, delivery of implant restoration (baseline), one year of implant restoration and annually up to three years using resonance frequency analysis.
Implant failure rate Upto 36 months Implant failure rate will be assessed clinically after one year of implant restoration and annually up to three years.
- Secondary Outcome Measures
Name Time Method Descriptive evaluation of biological and technical complications associated with dental implant restorations Upto 36 months Descriptive evaluation of biological and technical complications will be recorded during the follow-up period
Changes in peri-implant marginal bone level (in mm) Upto 36 months Changes in peri-implant marginal bone level will be assessed at implant placement, delivery of implant restoration (baseline), one year of implant restoration and annually up to three years using standardized peri-apical radiograph. The changes in peri-implant marginal bone levels will be recorded in millimeters
Patient postoperative experience ( visual analogue scale ) Upto 10 days Patient postoperative experience will be assessed using visual analogue scale during the first week following implant placement; the scale consists of a 10cm line, with end points representing 0 ('no pain') and 10 ('unbearable/worst pain'). The participant will be asked to place a mark on he line indicating the level of pain that he/she experienced.
