NCT06178536

Brief Summary

The aim is to clinically and radiographically assess a novel wedge implant placed in narrow ridges.

  • 60 wedge implants (Rex Implants, Columbus, OH, USA) will be placed using Piezosurgery® following either a bone consumption (n=30) or bone expansion technique (n=30). Each group (bone consumption and bone expansion) will be divided into 2 surface treatments: machined transcortical portion (n=15) and roughened transcortical portion (n=15).
  • Record the time needed to place each implant.
  • ISQ will be evaluated at Day 0, 3 weeks, 6 weeks, 3 months, 4 months, and 6 months after implant placement.
  • Periapical radiographs will be performed at implant placement, loading. and 1, 3, and 5 years after loading to assess marginal bone stability.
  • Buccal bone height and lingual and buccal bone thickness will be recorded post-intervention, at the time of functional loading, and at 12, 36, and 60 months after loading with CBCT.
  • Digital impressions will be taken post-operatively, at loading and at 12 months after loading to monitor gingival profile.
