Dr. Minas Leventis, DDS, MSc, PhD.


A 70-year-old female patient, non-smoker, with non-contributory medical history presented with a failing upper right central incisor (UR1) due to non-restorable subgingival cervical caries. The treatment plan consisted of extraction of UR1, immediate implant placement with immediate loading with a temporary crown, and placement of the final restoration 4 months later.

The “atraumatic” flapless removal of UR1 is important in order not to damage the surrounding hard tissues and to preserve intact the supra-crestal gingival complex.

After thorough debridement of the socket with Lucas curettes, a sharp pilot drill was used to create the initial osteotomy. A co-axis 12° direction guide pin was used to verify the correct direction of the initial osteotomy, as an implant with a 12° angle correction of the implant-abutment interface will be placed.

The osteotomy was finalized using the specific drill shank and a Southern Inverta body-shift 12° co-axis implant was placed, achieving excellent initial stability. Both bone and soft tissue zones were grafted using a synthetic b-TCP/Calcium Sulfate bone substitute. A prefabricated PEEK temporary cylinder was connected and a screw-retained temporary crown was fabricated.

The access hole of the provisional crown was sealed with SilverPlug®.

Oxygen-releasing Bluem oral gel was applied immediately post-op and given to the patient to use at home twice a day for a week. Amoxicillin 500mg x 3 for 5 days and paracetamol were prescribed.

The clinical view 4 months post-op shows very healthy keratinized soft tissues and excellent preservation of the architecture of the ridge. No inflammation, no smell when removing the temporary crown.

Final screw-retained restoration. Zirconia crown on a custom base Atlantis anodized abutment. Scrubbing with oxygen-releasing Bluem solution to disinfect the prosthetic canal, and sealing with SilverPlug@.

2.5 months after loading the final restoration, the soft tissues mature and the papillae grow back. The design and 3D positioning of the implant, the emergence profile of the provisional and final restorations, the absence of soft tissue inflammation and the quality of the regenerated bone are among the important factors which affect our results.
