RESUMO
Esta série de casos apresenta os procedimentos cirúrgicos e protéticos da técnica Facco. Dez pacientes (três homens e sete mulheres), entre 58 e 72 anos de idade, com maxilas totalmente desdentadas (Cawood e Howell Classes V ou VI) foram selecionados após exames clínicos, radiográficos e tomográficos. De posse dos guias cirúrgicos, sob anestesia e após o descolamento mucoperiosteal, dois implantes dentários convencionais foram colocados na região anterior da maxila e dois implantes dentários foram colocados na região zigomática aliados aos pilares Z. Com a transferência do posicionamento destes implantes, as próteses provisórias acrílicas foram colocadas até três dias depois. As próteses definitivas com barras metálicas foram instaladas seis meses mais tarde, e todos os pacientes receberam instruções de higiene oral, com retorno trimestral no primeiro ano e depois anualmente. Com dois anos de acompanhamento clínico e radiográfico, nove complicações (cinco biológicas e quatro mecânicas) foram observadas e tratadas: perda do implante anterior (1), perda do implante zigomático (1), contaminação do pilar Z (1), deiscência gengival (1), perda de torque no pilar Z (1), afrouxamento do parafuso da prótese (1) e fratura em dente artificial (2). Este relato de casos demonstra que o novo sistema de ancoragem zigomática (implante convencional associado ao novo pilar Z) e combinado com implantes dentários na região anterior foi capaz de suportar uma prótese total fixa de forma satisfatória, apresentando excelente função durante um acompanhamento de dois anos, demonstrando ser uma alternativa para a reabilitação das maxilas atróficas.

ABSTRACT
This case series presents the surgical and prosthetic procedures of the Faccoʼs technique. Ten patients (3 men, 7 women) between 58 and 72 years-old, with totally edentulous maxillae (Cawood and Howellʼs Classes V or VI), were selected after clinical, radiographic and tomographic examinations. With the surgical guides fabricated, under anesthesia and after mucoperiosteal releasing, two conventional dental implants were placed in the anterior maxilla, followed by two conventional dental implants in the zygomatic region allied to the Z abutments. Provisional acrylic prostheses were placed up to 3 days later. Definitive prostheses with metallic infrastructures were installed six months later, and all the patients received oral hygiene instructions, with follow-ups each three months in the first year and annually thereafter. Within two years of clinical and radiographic examinations, 9 complications (5 biological, 4 mechanical) were observed and treated: implant loss in the anterior area (1), implant loss in the zygoma area (1), Z abutment contamination (1), gingival dehiscence (1), Z abutment torque loss (1), prosthetic screw loosening (1), artificial tooth fracture (2). This case series demonstrates that the new zygomatic anchorage system (conventional dental implant associated with the new Z abutment) and combined with dental implants in the anterior region, was able to satisfactorily support a complete, fixed denture, showing excellent results during a 2-year follow-up, proving to be an alternative for the rehabilitation of atrophic maxillae.
Key words – Atrophic maxilla; Zygomatic bone; Dental implants; Z abutment, Faccoʼs technique (Técnica Facco).
