Clinical evaluation of immediate implants using different types of bone augmentation materials

Area of Science:

• Dental Implantology
• Oral Surgery
• Periodontology

Background:

• Immediate implant placement into fresh extraction sockets is a recognized safe and predictable dental procedure.
• Limited scientific evidence exists on the healing patterns and osseointegration of immediate implants, particularly concerning different grafting materials.

Purpose of the Study:

• To evaluate the healing pattern and osseointegration of dental implants placed immediately into fresh extraction sockets.
• To compare the efficacy of two different graft materials (Dem bone® and G-Bone®) in conjunction with immediate implant placement.

Main Methods:

• 30 patients received immediate implants in fresh extraction sockets, randomly assigned to two groups.
• Group A used Dem bone® (freeze-dried bone allograft), and Group B used G-Bone® (modified hydroxyapatite).
• Clinical and radiographic evaluations were performed at baseline, 3, 6, 9, and 12 months, with statistical analysis.

Main Results:

• No implant failures were recorded during the 1-year follow-up period.
• Mean bone levels at the implant sites were maintained or showed improvement.
• Both graft materials demonstrated comparable effectiveness in supporting osseointegration and bone maintenance.

Conclusions:

• Immediate restoration of single-tooth implants in fresh extraction sockets is a viable option for tooth replacement.
• Both freeze-dried bone allograft and modified hydroxyapatite are equally effective grafting materials for this procedure.
