Comparison of Different Suturing Techniques in Post-Extraction Socket Healing

The process of post-extraction socket healing is critical for ensuring proper tissue repair and minimizing complications in dental practice. Suturing techniques play a pivotal role in this process, influencing wound closure, hemostasis, and overall healing.

This prospective clinical trial involved 80 participants who required single-tooth extractions. Patients were randomly assigned to four groups, each receiving a distinct suturing technique: simple interrupted sutures, horizontal mattress sutures, vertical mattress sutures, and continuous sutures. Standardized assessments, including clinical examination and cone-beam computed tomography (CBCT) scans, were performed at baseline, 1 week, and 4 weeks post-extraction. Wound dehiscence, soft tissue healing, and bone preservation were evaluated.

At 1-week post-extraction, the continuous suture group exhibited the lowest rate of wound dehiscence (5%) compared to other groups (simple interrupted, 15%; horizontal mattress, 10%; vertical mattress, 12%). Soft tissue healing scores at 4 weeks were significantly higher in the continuous suture group (8.7 ± 0.5) than in the other groups (simple interrupted, 7.2 ± 0.8; horizontal mattress, 7.8 ± 0.7; vertical mattress, 7.5 ± 0.6). CBCT analysis revealed superior bone preservation in the continuous suture group (98% remaining bone volume) compared to the other groups (simple interrupted, 92%; horizontal mattress, 95%; vertical mattress, 94%).

This study demonstrates that the continuous suturing technique offers advantages in post-extraction socket healing, including reduced wound dehiscence, improved soft tissue healing, and better bone preservation.
