Alveolar Ridge Resorption After Extraction
Conditions
Keywords
Tooth Extraction, Modified Socket Shield Technique
Brief summary
This study aimed to evaluate the dimensional changes in the alveolar ridge after tooth extraction using the socket shield technique without immediate implant placement. The changes using CBCT were assessed, focusing on the preservation of the ridge for delayed implant placement. This research could help improve dental implant outcomes by preserving bone and soft tissue structures.
Detailed description
In this clinical trial, the dimensional changes in the alveolar ridge following tooth extraction were investigated using the socket shield technique. The socket shield technique involved partial retention of the root structure to preserve the surrounding bone and soft tissues. No immediate implant placement was performed, and the ridge changes were assessed at multiple time points through CBCT scans. The study included a specified sample size, and participants underwent a follow-up of 6 months after socket shield preparation. This research aimed to provide insights into how well the socket shield technique preserves ridge dimensions over time, potentially optimizing future implant stability.
Interventions
PROCEDUREModified Socket Shield Technique
The modified socket shield technique involves partial retention of the buccal aspect of the tooth root during extraction to preserve the surrounding alveolar bone and soft tissue. This technique is used to optimize the condition for delayed implant placement by preventing resorption of the alveolar ridge.
PROCEDUREConventional Tooth Extraction
Conventional tooth extraction involves the complete removal of the tooth without the use of the socket shield technique. This arm served as the control group, with alveolar ridge changes observed and compared with those in the experimental arm over time.

Intervention model description
This study followed a parallel-group design. Participants were randomly assigned to two groups: one received the modified socket shield technique and the other received conventional extraction without the socket shield. Both groups were monitored after 6 months to compare alveolar ridge preservation outcomes, with delayed implant placement performed in both groups at 6 months after tooth extraction.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Alveolar Ridge Width Changes | 6 months post-extraction | This outcome measure assesses changes in the alveolar ridge width following tooth extraction using either the modified socket shield technique or conventional extraction. Measurements were obtained through CBCT imaging at baseline and 6 months post-extraction. Unit of Measure: Millimeters (mm) |
| Bone Plate Height Changes | 6 months post-extraction | This outcome measure assesses changes in the bone plate height following tooth extraction using either the modified socket shield technique or conventional extraction. Measurements were obtained through CBCT imaging at baseline and 6 months post-extraction. Unit of Measure: Millimeters (mm) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Primary Implant Stability | At the time of implant placement, typically 6 months post-extraction. | This outcome measure assessed the primary stability of dental implants placed after using either the socket shield technique or conventional extraction. Implant stability was evaluated using resonance frequency analysis (RFA) at the time of implant placement. |
