S-Mini in the Lower Anterior Region for Implant Placement in a Narrow Ridge

Case Summary 🔎

Patient Information

• Age/Sex: 61-year-old Male

• Systemic Condition: Hypertension (well-controlled with medication)

Clinical Findings

• Tooth Site: #33

• Oral Examination: Extensive apical pathology observed on #33

• Diagnosis: Apical Periodontitis on #33

Clinical Summary

The patient presented with pain in the mandibular anterior region. Radiographic analysis revealed a severe apical lesion affecting tooth #33, indicating the necessity of extraction followed by implant placement. Given the extensive inflammation, a delayed protocol was chosen. An S-mini implant, optimized for anterior sites, was placed 7 months after extraction. Prosthetic restoration was completed with excellent functional and aesthetic outcomes. At the 8-year follow-up, the implant remained clinically and radiographically stable.

Treatment Plan

• Extraction of tooth #33

• Delayed implant placement

• Final restoration using a Zirconia crown

• Periodic follow-up evaluations

Conclusion

• Placement of S-mini implant in the mandibular left canine

• Final restoration with Zirconia crown

• Periodic follow up with stable long term outcomes

Case Presentation

1️⃣ Pre-Op

• Radiographic examination revealed a severe apical lesion on tooth #33, indicating the need for extraction and subsequent implant placement.

2️⃣ Extraction & Healing

• After extraction, inflammatory tissue was thoroughly debrided. Bone grafting was performed using Regenoss (allograft), and the site was covered with a pedicle flap to support soft tissue healing.

• TissueBond was applied to stabilize the flap and assist in maintaining soft tissue volume and supporting gingival contours.

• At 5 months post-extraction, soft tissue healing and partial resolution of inflammation were observed clinically and radiographically.

3️⃣ Implant Placement in a Narrow Ridge

• 7 months post extraction, good healing and healthy gingival contours were observed.

• Using the S-mini kit and drills, depth-controlled drilling was performed based on the reference markings in a flapless approach.

• ∅3.0*13mm S-mini implant was placed.

• The implant was accurately placed in the ideal position without exposure, despite the narrow ridge width.

S-mini Fixture

S-mini is a one-body implant designed for narrow ridges, such as the mandibular anterior region. It is available in diameters of 2.5, 3.0, and 3.5 mm, and is placed using a dedicated surgical kit for precise and safe placement.
