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

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.

Treatment and study plan

Injectable Alloplastic Bone Graft

Device

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

Primary outcomes

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.
