Treatment Planning
．Implantation of CMI IS-ll active simultaneously with sinus floor elevation in region d26 and augmentation. ．6 months of healing period. ．Later step-by-step implantations in the other easier regions.
Perforation occurred while SLA drilling. The defect was measured approximately 4 to 5mm.
You can still go on, reparing perforation with a collagen membrane. In some cases we cannot avoid perforations but very often it may not be a huge problem.
Nice healing after 1 week!
