From: Round and flat zygomatic implants: effectiveness after a 1-year follow-up non-interventional study
a–d The preoperative virtual planning in the extremely atrophic maxilla of patient 5 is compared with the postoperative one-year CBCT. a represents the anterior right implant comparison; b is posterior right; c is anterior left; d is posterior left. The implant placed in the position of the second left premolar showed intrusive movement with no associated rotation or pain. 26 months after the surgery the implant is still in function. The implant was classified as success grade III. e Occlusal intraoperative view of the patient 5. Two Straumann ZAGA-Round were placed on the anterior zone and two Straumann ZAGA-Flat on the premolar/molar zone. Note the two different types of osteotomy designed to protect both sinus integrity and soft tissues. f Occlusal gingival picture of patient 5 illustrating the routine soft tissue assessment necessary to understand and report whether or not the rehabilitation is a success
