An interventional study of Osseodensification and Conventional drilling in Implant Assesment, sponsored by Gulf Medical University. Completed at 1 site in Egypt. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-04-29.

Primary implant stability and bone preservation are critical determinants of successful osseointegration, particularly in sites with low bone density. Conventional drilling removes bone and may reduce stability, whereas osseo-densification is a non-subtractive technique that compacts bone to enhance its density and strength.
Objective:
To compare osseo-densification and conventional drilling techniques in terms of implant primary stability, peri-implant bone density, and marginal bone loss during early healing.
Methods:
A double-blinded, randomized split-mouth clinical trial was conducted on eight participants requiring bilateral maxillary implants (n = 16 sites). Each patient received one implant using the osseo-densification technique (Densah burs, counterclockwise mode) and one using conventional sequential drilling. Cone-beam computed tomography (CBCT) was used to evaluate bone density and marginal bone levels at baseline, three, and six-months post-placement. Implant stability was measured immediately after insertion using resonance frequency analysis (Osstell ISQ). Data were analysed using t-tests and repeated-measures ANOVA (p \< 0.05).
Gulf Medical University is the lead sponsor of 40 studies on the registry; 16 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Systemically and medically healthy adults (>18 years old) of either sex.
Exclusion Criteria:
Systemic medical conditions that could compromise surgical healing or osseointegration (e.g., uncontrolled diabetes mellitus).
Procedure: Osseodensification
Procedure: Conventional drilling
osseo-densification is a recently introduced, non-subtractive drilling technique that utilizes specially designed densifying burs in a counterclockwise (densifying) mode to laterally compact and autograft bone along the osteotomy walls.\[9\] This compaction of trabecular bone increases bone density, enhances primary stability, and may improve long-term bone-to-implant contact.
Traditionally, implant osteotomies are prepared using conventional subtractive drilling, which removes bone to create space for implant insertion.
