The atrophic maxilla has characteristics, that can make it difficult to perform rehabilitation with osseointegrated implants. One of the ways to rehabilitate this patient is placement of zygomatic implants in the posterior region of the maxilla, which would support a total prosthesis. Although this technique has been used since the 1990s, the literature has shown few data on the preservation of these implants. The objective of this study was to conduct a study of the preservation of zygomatic implants installed in the period between 2006 and 2012.For this purpose, 13 patients, with 25 zygomatic implants were evaluated by means of a questionnaire, clinical and image examinations (panoramic radiography). The results of this research showed that 28% of zygomatic implants were lost.Implants that were not lost, continue to function and have no mobility. After clinical evaluation of the zygomatic implants, plaque was observed.The levels of gingival inflammation were mild, probing depth revealed shallow grooves in 08 patients, with no gingival recession. In the assessment of panoramic radiographs, absence of bone lesions was observed. The present studycould be concluded that: zygomatic implants had lower success rates than those described in the literature, with a considerable loss of implants.
