Replacement therapy and the immediate post-extraction dental implant

Area of Science:

• Dental Implantology
• Oral Surgery
• Biomaterials Science

Background:

• Immediate postextraction implant placement faces challenges with initial stability and soft tissue ingrowth, potentially leading to implant failure.
• Single-stage implants offer a streamlined approach but require careful management of the extraction socket environment.

Purpose of the Study:

• To evaluate the effectiveness, reliability, and placement of single-stage implants in extraction sockets using a synthetic bone substitute.
• To assess the long-term outcomes of this combined approach for dental restorations.

Main Methods:

• Hopeless teeth were extracted, followed by the insertion of one-stage cylindrical screw implants (hollow and solid) with a composite polymer synthetic bone substitute.
• No membrane was used, and prostheses were placed three to six months postoperatively.

Main Results:

• Excellent initial results were observed, confirmed by 7 to 10 years of follow-up.
• Solid screw-type implants demonstrated a lower failure rate compared to hollow screw-type implants.
• Osseointegration in extraction sockets was enhanced when using the synthetic graft material.

Conclusions:

• One-stage implant placement in extraction sockets combined with synthetic bone substitute is effective and reliable.
• The simplicity of this technique does not compromise outcome predictability.
• This method provides a simple, quick, cost-effective, and secure way to achieve implant-supported restorations.
