Survival and complications of zygomatic implants: a systematic review

Abstract

Despite the high survival rate observed, there is an impending need for conducting randomized controlled clinical trials to test the efficacy of these implants in comparison with the other techniques to treat the atrophic maxilla. Thus, the findings reported in the review must be interpreted with considerable caution. Moreover, more studies with longer follow-up periods involving adequate number of ZIs are needed. This will help to obtain a better understanding of the survival of ZIs in a long term. It is suggested that multicenter, randomized controlled clinical trials and longer clinical studies should be implemented in this area, before recommending routine use of ZIs for patients could be given. The placement of zygomatic implants requires very experienced surgeons because it is not risk free since delicate anatomic structures such as the orbita and brain may be involved.

Zygomatic implant: Late complications in a period of 12 years of experience

“…(15) Recent systematic review, evaluated the level of survival and presence of complications in a period of 12 years. Only 42 studies or clinical cases of zygomatic implant were included in the criteria selection.…”

“…Finally, the authors conclude the necessity of more studies with a long period of follow up. (15) In relation to the access, the opening of anterior wall, as practiced by the Caldwell Luc technique, contribute to more risk of complication postoperative as sensorial alterations, penetration of soft tissue inside of the sinus, creating sinusitis and other pathologies like surgical cysts. (17,18) However, authors showed the absence of the relation of the opening of anterior wall, in this surgery, with complications.…”

“…(6)(7)(8)(9)(10)(11)(12)(13)(14) Recent systematic review studies reported the survival and presence of complications related of zygomatic fixation. (15) They conclude that the studies with a high level of evidence are scarce. (15) Here in, we report late complications related to rehabilitation of the atrophic maxilla, using zygomatic fixations, during 12 years of experience.…”

Maxillary restoration with complete maxillary prosthesis supported by implants with immediate loading: clinical retrospective study of 48 cases

“…In the posterior region, where bone quality and quantity are not always optimal, surgical alternatives have been proposed: short implants [10], onlay bone graft, sinus floor elevation, or implants in specific anatomical areas such as the zygomatic bone [11], the pterygoid region [12], or the maxillary tuber [13]. Each of these techniques have their own advantages and disadvantages, but they all have limitations and require advanced surgical expertise.…”
