Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

tapered implant with conventional preparation

The osteotomy will be performed following the manufacturer's standard drilling sequence without osseodensification.

This group will serve to evaluate the effect of conventional implant site preparation on the primary and secondary stability of tapered implants

Group Type EXPERIMENTAL

Dental Implant Placement with Osseodensification or Conventional Drilling

Intervention Type PROCEDURE

Placement of tapered or cylindrical dental implants using osseodensification (bone-compacting technique) or conventional drilling to evaluate implant stability.

tapered with osseodensification

The osteotomy will be prepared with densifying burs operated in a non-subtractive, counterclockwise direction to compact and preserve bone tissue.

This approach aims to enhance bone density and improve the primary and secondary stability of the tapered implants

Group Type EXPERIMENTAL

Dental Implant Placement with Osseodensification or Conventional Drilling

Intervention Type PROCEDURE

Placement of tapered or cylindrical dental implants using osseodensification (bone-compacting technique) or conventional drilling to evaluate implant stability.

cylindrical implant with conventional preparation

The osteotomy will be performed following the standard sequential drilling protocol recommended by the manufacturer, without applying osseodensification.

This group will be used to assess the effect of conventional implant site preparation on the primary and secondary stability of cylindrical implants

Group Type EXPERIMENTAL

Dental Implant Placement with Osseodensification or Conventional Drilling

Intervention Type PROCEDURE

Placement of tapered or cylindrical dental implants using osseodensification (bone-compacting technique) or conventional drilling to evaluate implant stability.

cylindrical with osseodensification

The osteotomy will be performed using densifying burs in a non-subtractive, counterclockwise direction, which compacts and preserves the surrounding bone tissue.

This method is intended to increase bone density and improve both primary and secondary implant stability for cylindrical implants

Group Type EXPERIMENTAL

Dental Implant Placement with Osseodensification or Conventional Drilling

Intervention Type PROCEDURE

Placement of tapered or cylindrical dental implants using osseodensification (bone-compacting technique) or conventional drilling to evaluate implant stability.
