Summary

This study aims to compare the clinical performance of 4 mm short implants supporting cross-arch fixed reconstructions in the edentulous mandible either with a combination of two short implants as distal support and two implants of conventional length placed in the interforaminal region, or with a combination of four short implants as distal support and two interforaminal implants of conventional length.

Conditions

  • Jaw Edentulous

Interventions

DEVICE

Roxolid short implant, 4 mm length (4)

Placement of a combination of four short implants (in positions 35/45, 36/46) as distal support and two implants of conventional length (in positions 33/43) in the interforaminal region, in order to support a cross-arch fixed screw-retained prosthesis.
