The hypothesis was accepted. Compressing implants with single-drill bone preparation demonstrated many clinical and histological advantages with respect with to standard implant drilling procedures and classical implant shape and design in low-density bone type. It is possible to summarize the advantages of this technique as follows: higher bone to implant contact percentage than the control group (due to the innovative fixture geometry that causes bone compaction), speed of execution (only one-step preparation in low-density bone), high primary implant stability (undersized preparation matched to special fixture shape and thread geometry), high manageable final implant position, high patient comfort, and less cost.

The present pilot study involves only two animals; this limitation could influence the statistical observations we have discussed. Future in vivo studies with a bigger animal numbers or clinical studies with a high sample size are needed in order to confirm the results of the present paper.
