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