Full arch implant placement on the maxilla using Simplant software

Situation

The patient was a 71 years old male with residual maxillary dentition using a partial denture of the upper arch.

Pre-operative Radiograph

Intra-oral photograph : Teeth showed grade 2 mobility.

To position the implants correctly a CBCT was performed and Simplant software was used to design the implant location.

Before the procedure a wax up and mock up were made as well as a navigation splint and a splint for temporary restoration. Under infiltration anesthesia the residual teeth were extracted.

Implants were immersed with the force of 35 to 45 Ncm.

A closed lift was performed for the Schneiderian membrane of the right maxillary sinus. Implant 16 was stabilized at 10 Ncm and was not loaded immediately. A temporary bridge was made at full occlusion on temporary connectors screwed to the implants with the force of 20 Ncm.

Post-operative Radiograph

After stability was obtained (4.5 months) impressions were collected.

The metal framework supported by standard connectors was tried in.

The restoration was then produced and finally cemented.
