Overview

The effect of osseodensification versus conventional implant site preparation on implant stability for tapered and cylindrical dental implants.

Dental implant stability is a key factor influencing the success of osseointegration and the long-term prognosis of implant-supported restorations. The stability of an implant can be divided into two phases: primary stability, which depends on the mechanical engagement between the implant and the surrounding bone at the time of placement, and secondary stability, which develops through biological bone remodeling and osseointegration over time. Traditional (conventional) drilling techniques used for implant site preparation are subtractive in nature, meaning they remove bone to create space for the implant. However, this process may reduce bone density at the osteotomy walls, particularly in low-density bone, potentially compromising initial stability. Osseodensification (OD) is a relatively new, non-subtractive drilling technique introduced by Huwais and colleagues. Instead of removing bone, OD uses specially designed, counterclockwise rotating burs (Densah burs) that laterally compact and densify bone along the walls of the osteotomy. mplant macrodesign-particularly whether the implant is tapered or cylindrical-also influences stability outcomes. Tapered implants typically provide higher primary stability due to their wedging effect and better adaptation in underprepared osteotomies, especially in soft bone. Cylindrical implants, while providing more uniform stress distribution, may rely more heavily on bone density and precise site preparation for achieving optimal stability.

Outcomes

Primary Outcomes

primary stability

Primary stability refers to the mechanical stability of a dental implant (or any bone implant) immediately after placement, before bone healing or osseointegration occurs. It mainly depends on bone quality and density, implant design, and surgical technique.it measured using the osstell through Resonance Frequency Analysis,Higher ISQ values indicate greater primary stability.more than 70 ISQ is considerd high stability. Achieving good primary stability is crucial for implant success, as it helps prevent micromovements and supports proper secondary (biological) stability during healing,

Time frame: at the time of surgery

Secondary Outcomes

secondary stability

Secondary stability refers to the biological stability of a dental implant that develops over time through osseointegration, the direct structural and functional connection between the implant surface and surrounding bone. Unlike primary stability, which is mechanical, secondary stability results from bone healing, remodeling, and new bone formation around the implant ..it measured using the osstell through Resonance Frequency Analysis,Higher ISQ values indicate greater stability.more than 70 ISQ is considerd high stability.

Time frame: after 12 weeks
