Cover Screw vs Healing Abutment on Osseointegration

NCT07687615 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 50

No results posted yet for this study

Summary

This randomized split-mouth clinical trial aims to compare the effects of using a cover screw versus a healing abutment on early implant stability and osseointegration. Patients requiring at least two dental implants will receive both interventions in a split-mouth design, with one implant randomly assigned to the cover screw group and the contralateral implant assigned to the healing abutment group. Implant stability will be assessed using resonance frequency analysis (RFA) and Implant Stability Quotient (ISQ) measurements during the healing period.

Conditions

  • Implant Stability Quotient
  • Healing Abutment
  • Cover Screw

DEVICE

Healing Abutment

A healing abutment was connected to the dental implant immediately after implant placement using a one-stage surgical protocol.

DEVICE

Cover Screw

A cover screw was connected to the dental implant immediately after implant placement using a conventional two-stage surgical protocol.
