Book excerpt: INTRODUCTION: Zygomatic implants (ZIs) appeared at the late eighties to rehabilitate patients who had suffered resection of the maxilla. Nowadays, they are also used in patients with severe maxillary atrophy.Purpose: To assess the survival rate of ZIs; the prevalence of complications and satisfaction level of the patients based on previously published studies with a medium- and long-term follow-up.METHODS: An electronic search was performed in January/2017 in PubMed/Medline database and was supplemented by hand-searching. Clinical case series and cohort studies of ZIs were included with a minimum follow-up of 39 months. The following variables were extracted from these papers: number of patients, number of zygomatic and standard implants, duration of the study, surgical technique, type of prosthesis, type of loading, complications, survival rate of the ZIs and satisfaction level of the patients. RESULTS: Forty-four studies were included, comprising 3589 ZIs in 1638 patients. Sixty-four ZIs were lost in a medium term (97.82% survival rate) and 26 in long-term (95.97% survival rate). The most frequent surgical complications were hematoma and paresthesia (2%), being more prevalent in the classic surgical technique. The most common biological complication was sinusitis with 7.8%, followed by periimplantitis (4.5%), mucositis (2.6%), oroantral fistula (0.46%), gingival recession (0.19%) and gingival hypertrophy (0.16%). Among prosthetic complications we found fractures of teeth (13.73%) and prosthesis (12.5%); loosening of screws (6.56%) and to a lesser extent changes of prosthesis, implant fractures, overload or deformation of screws (0.05%). The maximum satisfaction level of patients rehabilitated was 89.4%, 87.4% and 84.34% for aesthetics, function and phonetics, respectively.CONCLUSIONS: The survival rate of the ZIs after a minimum period of 39 months of follow-up, is very high, with a low percentage of complications. Patients also appear to be adequately satisfied with the treatment. Rehabilitation with ZIs is an alternative of treatment which increases the predictability of the results and decrease the morbidity and treatment time in patients with severe maxillary atrophy.
