Clinical and Radiographic Evaluation of Delayed Dental Implant Placement After Socket Preservation Using Injectable Bone Graft

January 20, 2026 updated by: Suez Canal University

Clinical and Radiographic Evaluation of Delayed Implant Placement Following Socket Preservation With Injectable Alloplastic Bone Graft. A Randomized Controlled Study.

This clinical study aims to evaluate the clinical and radiographic outcomes of delayed dental implant placement following socket preservation using an injectable alloplastic bone graft material.

The study will include patients who require tooth extraction and are candidates for implant placement.

After tooth extraction, the socket will be preserved using the bone graft material, and dental implants will be placed after a healing period.

Clinical and radiographic assessments will be performed to evaluate bone quality, bone height, and implant stability.

The goal of this study is to determine the effectiveness of injectable alloplastic bone grafts in maintaining the alveolar ridge and improving the success of delayed implant placement.

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
No Intervention: Control Group
Extraction sites left to heal naturally without any bone grafting material before delayed implant placement. Dental implants will be placed after the natural healing period, and clinical and radiographic evaluations will be performed to assess ridge dimensions and implant outcomes
Experimental: Study Group
Extraction sockets will be preserved using an injectable alloplastic bone graft material immediately after tooth extraction. After a healing period, delayed implant placement will be performed. Clinical and radiographic measurements will be used to evaluate ridge preservation and implant success.
Device: Injectable Alloplastic Bone Graft
Following tooth extraction, socket preservation will be performed using an injectable alloplastic bone graft material composed of biocompatible synthetic components. The material will be placed into the extraction socket to maintain ridge dimensions and promote bone regeneration. After a healing period of several months, delayed implant placement will be performed, and clinical and radiographic evaluations will assess ridge preservation and implant success

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Implant stability at the time of delayed implant placement
Time Frame: At the time of delayed implant placement (approximately 4 to 6 months after tooth extraction)
Implant stability will be assessed at the time of delayed implant placement using resonance frequency analysis (RFA) to obtain implant stability quotient (ISQ) values. The ISQ readings will be used to evaluate the effect of socket preservation with injectable alloplastic bone graft on implant stability in comparison to sites without grafting.
At the time of delayed implant placement (approximately 4 to 6 months after tooth extraction)
