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).
