Cover Screw vs Healing Abutment on Osseointegration
EFFECTS OF COVER SCREW AND HEALING ABUTMENT ON EARLY IMPLANT STABILITY: A RANDOMIZED CONTROLLED CLINICAL TRIAL
연구 개요
상태
개입 / 치료
상세 설명
This prospective randomized split-mouth controlled clinical trial evaluates the effects of cover screw placement and healing abutment placement on early implant stability and osseointegration. Systemically healthy patients requiring at least two dental implants will be enrolled. Using a split-mouth design, each participant will receive both interventions, with one implant randomly allocated to receive a cover screw (two-stage protocol) and the contralateral implant to receive a healing abutment (one-stage protocol).
Implant stability will be evaluated by insertion torque and resonance frequency analysis (RFA). Implant Stability Quotient (ISQ) values will be recorded at implant placement and at the 3-month follow-up. The primary objective is to compare changes in implant stability (ΔISQ) between the two treatment protocols. Secondary outcomes include implant survival, peri-implant soft tissue healing, and postoperative complications.

실험적: Healing Abutment
Dental implants were restored with a healing abutment at the time of implant placement using a one-stage surgical protocol.
Implant stability and osseointegration were evaluated during the follow-up period.
|
A healing abutment was connected to the dental implant immediately after implant placement using a one-stage surgical protocol.

활성 비교기: Cover Screw
Dental implants were restored with a cover screw at the time of implant placement using a conventional two-stage surgical protocol.
Implant stability and osseointegration were evaluated during the follow-up period.
