Narrow Ridges – A common Clinical Challenge

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.

AN IMPLANT DESIGNED FOR THE ANATOMY
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

SCIENTIFICALLY-PROVEN CLINICAL SUCCESS
In the preliminary, multicenter, clinical study introducing this new implant morphology, REX PiezoImplants placed in narrow ridges (3.5 mm to 5 mm wide) had a 98.3% survival rate after one year of loading.
These favorable results were obtained in ridges of reduced width, including cases of suboptimal
vascularization, which is essential for osteointegration.
Crestal bone resorption was found to be less than 1 mm after one year of loading, that is, the same favorable result obtained with conventional screw-form implants in large crestal width.
Additionally, pain associated with REX PiezoImplant placement was extremely low, and experienced over
a short duration. These findings are definitely more favorable than those associated with implant placement in combination with bone augmentation procedures.
Lastly, the subjective experience reported by operators and patients was extremely positive due to reduced surgical difficulty.
