Reabilitação oral com levantamento de seio maxilar e próteses implantossuportadas – relato de caso com três anos de acompanhamento

RESUMO

Este artigo descreveu o tratamento de um paciente com 54 anos de idade após dez anos de uso de próteses totais na maxila e na mandíbula. Após exame clínico (Classe VI de Cawood e Howell) e concordância com o plano de tratamento, o levantamento bilateral do seio maxilar foi realizado e um biomaterial xenógeno (partículas 0,25-1 mm) foi acomodado. Seis meses depois, oito implantes dentários (diâmetros de 3,75 mm e 5 mm; comprimentos de 7 mm e 13 mm) foram posicionados nas regiões anterior (11/21) e posterior (13/23, 15/25 e 16/26) seguindo-se as imagens de TCFC e planejamento protético. Na mandíbula, quatro implantes de 3,75 x 13 mm foram colocados entre os forâmens. Em seguida, as próteses totais parafusadas foram instaladas respeitando-se os tempos de cicatrização e acompanhadas durante três anos, sem intercorrências observadas.

ABSTRACT

This article describes the treatment of a 54 years-old patient a er 10 years of use of complete dentures in the maxilla and mandible. A er clinical examination (Cawood and Howell´s Class VI) and agreement with the treatment planning, bilateral maxillary sinus li ing procedures were performed and a xenogeneic biomaterial (0.25-1 mm particle size) was accommodated. Six months later, eight dental implants (3.75 mm and 5 mm diameters; 7 mm and 13 mm lengths) were positioned in the anterior (11/21) and posterior (13/23, 15/25, 16/26) regions, following CBCT images and prosthodontic prescriptions. In the mandible, four dental implants (3.75 mm x 13 mm) were installed between the mental foramina. Then, screw-retained, complete, total Þ xed dentures were installed respecting the healing times and followed-up for three years, with no complications observed.

Key words – Sinus ß oor augmentation; Dental implants; Dental prosthesis; Mouth rehabilitation.
