This case by Dr. Sang Bong Jung of Nul Purun Dental Clinic in Busan, South Korea highlights a successful 3-year follow-up of a Dentis SQ Mini 4.0 x 10mm implant placed in the maxillary right second premolar site. It reflects the importance of careful diagnosis, effective patient communication, appropriate implant selection, and long-term maintenance in achieving successful outcomes in implant therapy.
Initial Presentation
Date: March 30, 2021
The patient presented with a large periapical lesion on the maxillary right second premolar. Despite the severity of the lesion, the patient requested nonsurgical retreatment rather than extraction. Dr. Jung proceeded with retreatment of the root canal, aiming to preserve the natural tooth.
Initial X-rays and images show the extensive lesion.
Lack of Healing and Decision to Extract
Date: June 15, 2021
After 3 months of endodontic retreatment, the lesion showed no significant reduction in size. After discussing the situation with the patient, Dr. Jung decided to proceed with extraction of the affected tooth.
Images show the extracted site and persistent lesion.
Bone Grafting
Date: July 23, 2021
Following extraction, granulation tissue was thoroughly removed, and a significant bone defect over 10mm was noted. GBR (guided bone regeneration) was performed using a xenograft without the need for additional materials.
Intraoral photos and radiographs show the extent of the defect and graft application.
Post-GBR Follow-Up
Date: August 5, 2021
The surgical site showed good healing progress, and the sutures were removed without complications.
Follow-up photos document healing after GBR.
Implant Placement
Date: November 16, 2021
A Dentis SQ Mini 4.0 x 10mm fixture was placed with a torque of 25 Ncm. Site stability was achieved and post-op healing proceeded uneventfully.
X-ray confirms ideal placement.
Suture Removal & Healing
Date: December 27, 2021
Sutures were removed and soft tissue healing was satisfactory.
Impression Taking and Prosthesis Delivery
Date: March 22, 2022
An impression was taken for the final prosthesis.
Date: April 1, 2022
The final prosthesis was delivered and installed. Functional and esthetic outcomes were excellent.

Long-Term Follow-Up
September 19, 2022
October 27, 2023
April 15, 2025
Progress photos and radiographs confirm excellent maintenance.
Regular check-ups revealed no complications. The implant and prosthesis remained stable and functional, with no signs of bone loss, inflammation, or prosthetic issues.
CT Confirmation
Date: May 30, 2025
A CT scan of the implant site confirmed that the implant was well-maintained with stable surrounding bone structure and no abnormalities.
Conclusion
This case demonstrates the reliability and performance of the Dentis SQ Mini implant over a 3-year period, even in sites with significant bone defects. Careful planning, high-quality materials, and patient compliance played key roles in the successful outcome.
Dentis SQ Mini continues to be a trusted choice for clinicians looking for compact yet powerful solutions in challenging cases.
