Dental Implants Placed in Fresh Human Extraction Sockets Without Osteotomy: A Case Series

Area of Science:

• Dental Implantology
• Oral Surgery
• Biomaterials

Background:

• Immediate implant placement in fresh extraction sockets offers potential benefits for treatment efficiency.
• Traditional methods often involve osteotomies, which may impact healing and stability.
• Evaluating non-osteotomy immediate implant placement is crucial for refining surgical protocols.

Purpose of the Study:

• To assess healing parameters of immediate dental implants placed without osteotomies in fresh extraction sockets.
• To examine resonance frequency analysis (RFA) trends and radiographic bone changes.
• To evaluate implant stability from placement to prosthetic restoration.

Main Methods:

• A case series of 10 implants in 8 patients using self-tapping, knife-shaped implants.
• Implants placed in molar, premolar, and incisor sockets without osteotomies.
• Resonance frequency analysis (RFA) and standardized radiographs recorded at three time points.

Main Results:

• All implants achieved high insertion torque (>35 Ncm) and initial implant stability quotient (ISQ) values.
• Median bone remodeling was 0.35 mm from placement to restoration.
• RFA values increased significantly from placement to pre-prosthetic stage (e.g., 64 to 76 ISQ buccolingually).

Conclusions:

• Immediate dental implants placed without osteotomies can achieve successful osseointegration and functional stability in select cases.
• The study demonstrates positive healing trends based on RFA and radiographic bone analysis.
• Larger cohort studies are recommended to validate these findings due to the small sample size.
