Atrophic maxilla is a common condition in older population;
some treatments are proposed with bone reconstruction
or zygomatic implant. Long-term follow up
show the efficiencies of zygomatic implant but limited
data are associated to consecutive patient. The aim of this
study was to evaluate retrospectively the zygomatic implants
performed consecutively in 29 patients. Data from
clinical records of 29 patients treated with zygomatic implants
were analyzed; were include patient with at least
10 month of prosthetic function. Four surgeons realized
all surgeries using local anesthesia with a slot technique
on local anesthesia; the variables analyzed were implant
survival, complications, prosthetic load and satisfaction
of patient; data collection was analyzed by descriptive
statistic and chi-square test with p<0.05 for significance
statistical. 67 zygomatic implants and 84 conventional
implants were installed in patients between 35 and 69
year old being 18 (62%) female and 11 (38%) male.The
main indication was the case of severe alveolar resorption
in 21 cases (72.41%), followed by failures in maxillary reconstruction
with bone graft in 4 (13.79%). The implant
success was 79.1% and the immediate or delayed load
was not associated to statistical difference (p=0.104). The
main complication was the loss of osseointegration and
mucositis. Analogue Visual Scale (AVS) for satisfaction
show acceptable esthetic and function. Finally we conclude
that zygomatic implant present adequate survivor
and a good response of patient; important complication
can be present in a learn curve for this surgery
