After tooth extraction the implant site was prepared in accordance with the manufacturer's instructions for the Nobel Biocare N1 Implant system. The pilot osteotomy was created with the OsseoDirector™, then the final osteotomy was created with the OsseoShaper™ to a torque of 23 Ncm. An N1 RP 13 mm implant was placed achieving 51 Ncm of final implant insertion torque.

The implant was placed approximately 3.5 mm below the buccal free gingival margin. The flat side of the trioval was placed on the buccal aspect in accordance with the manufacturer's instructions (left).

The Xeal™ N1 Base RP 1.75 mm was placed immediately after the implant placement and tightened to the final torque of 20 Ncm (right).

The N1 Base was placed using a plastic handle, then once in situ the final torque was achieved using the N1 Base screwdriver attached to the dedicated prosthetic torque wrench.

N1 Base in situ. The new trioval prosthetic platform is located about 1.75 mm below the buccal soft tissue level.

N1 Base titanium temporary abutment was placed in order to proceed with an immediate temporization using the fully digital workflow of a TempShell provisional. The screw access channel was closed with Teflon in order to protect the screw head during the restorative procedure.

The temporary abutment was fixed to the TempShell using flowable composite. The temporary restoration was then placed in situ and tightened to 20 Ncm with Omnigrip Mini. The clinical view shows the result immediately after the surgery.

The temporary restoration was removed 10 weeks after the surgery to take the final impression. Soft tissue volume, morphology and quality appeared stable and healthy (left).

Final impression was acquired using an intraoral scanner and the IOS Healing Abutment N1 Base. Clinical view and the X-ray show the IOS abutment in situ.

The final restoration on a Universal Abutment was designed and planned using DTX Studio™ Lab.

A NobelProcera® full-contour zirconia crown was cemented in the lab on the Universal Abutment in order to obtain a final screw-retained restoration (right).

Final result: Clinical and radiographic evaluation showed excellent marginal bone levels with ideal and stable soft tissue architecture. The screw access channel was closed with Teflon and composite.

Initial situation and the final result: Cinical views show excellent tissue stability.

X-ray and clinical evaluation after 9 months of function. Note the excellent bone and soft tissue health.
