The REX PiezoImplant System was designed specifically to manage reduced crestal width. Its rectangular section mimics the anatomy of the residual crestal bone, allowing for adequate bone thickness to be preserved on the vestibular and lingual sides. This level of bone preservation is not possible with traditional, screw-form implants because their circular section poses a geometrical discrepancy with the anatomy. The morphological advantages of REX PiezoImplants allow preserving a crestal thickness greater than 1.5 mm buccally and lingually even when the residual crest is only 3.5 mm
SUCCESSFUL IMPLANTOLOGY REQUIRES ADEQUATE CRESTAL BONE WIDTH Placing a dental implant in a narrow crest without adequate width can lead to dehiscence, increasing the risk of peri-implantitis. Because a peri-implant bone thickness of 1.5-2 mm is needed to reduce risk of dehiscence, crestal bone must be 6.5 - 7.5 mm wide for placement of a screw implant. Traditionally, clinical cases with horizontal defects have been solved using mini-implants or bone augmentation procedures. Both of these techniques are fraught with complications.
