Zy­go­ma­tic im­plants are used for prost­he­tic reha­bi­li­ta­tion of the se­ve­rely atrop­hic ma­xi­lla. The ori­gi­nal sur­gi­cal tech­ni­que (OST) at mo­dum Brå­ne­mark pres­cri­bed an in­tra-si­nus path­way of the im­plant from a pa­la­tal si­te en­tran­ce, and the pre­pa­ra­tion of an an­tros­tomy to allow vi­sua­li­za­tion du­ring in­ser­tion of the im­plant. Ho­we­ver, the most con­ca­ve is the ma­xi­llary an­te­rior wall, the mo­re mar­ked pa­la­tal po­si­tion of the im­plant head will be at­tai­ned. If the ma­xi­lla is very atrop­hic, the pa­la­tal en­tran­ce will oc­cur th­rough a thin cor­ti­cal bo­ne. Tho­se si­tua­tions will fre­quently end in­to bulky prost­he­tic cons­truc­tions, im­pai­red hy­gie­ne and even­tual la­te si­nu­sal com­pli­ca­tions. To over­co­me the OST draw­backs, dif­fe­rent sur­gi­cal ap­proa­ches, in­clu­ding the ex­tra-si­nus tech­ni­que, will be des­cri­bed. A no­vel pro­to­col ai­ming at pro­mo­ting a pa­tient-spe­ci­fic the­rapy na­med Zy­go­ma Ana­tomy- Gui­ded Ap­proach(ZA­GA), is ex­plai­ned with help of a cli­ni­cal ca­se. Using this met­hod allows avoi­ding the ope­ning of a win­dow or slot in­to the la­te­ral wall of the ma­xi­llary si­nus pre­vious to im­plant pla­ce­ment. The sur­gi­cal ma­na­ge­ment of the im­plant si­te is gui­ded by the ana­tomy of the pa­tient. Con­ser­va­tion of even­tual re­mai­ning al­veo­lar bo­ne is cri­ti­cal. The www. zy­go­ma­za­ga­cen­ters. com(ZZC) is for­med by an in­ter­na­tio­nal net­work of pro­fes­sio­nals trai­ned and cer­ti­fied in the ZA­GA phi­lo­sophy. Due to the ex­pe­rien­ce gat­he­red, the ZA­GA Cen­ter be­co­mes the true ex­pert in their area or city for the treat­ment of ma­xi­llary atrophy. The main fun­ction of the ZA­GA Cen­ter is to per­form the sur­gery ac­cor­ding to the ZA­GA met­hod and to equi­li­bra­te an im­me­dia­te fi­xed prost­he­sis.
