RESUMO
O objetivo desta série de casos foi sugerir uma nova técnica para elevação do assoalho do seio maxilar (ESM) – técnica transcrestal – utilizando insertos acoplados ao ultrassom piezoelétrico sem a necessidade de biomateriais. Nove pacientes normoreativos, com necessidade de reabilitação implantossuportada na região posterior de maxila, apresentando hiperpneumatização dos seios maxilares, receberam o procedimento de ESM pela técnica transcrestal utilizando insertos tipo copo dedicados ao ultrassom piezoelétrico. Ao final do período de observação de até três anos, um dos 15 implantes dentários apresentou perda precoce, sendo observado 100% de sucesso nas próteses e 92% nos implantes. A queixa dos pacientes se restringiu a um leve desconforto na área operada, controlado com medicamentos. O desenvolvimento de novos insertos para aparelhos de ultrassom piezoelétrico associou a segurança e delicadeza do corte do ultrassom com a morbidade reduzida do acesso transcrestal para ESM.

ABSTRACT
The aim of this case series was to suggest a new technique for sinus floor elevation (SFE), the transcrestal technique, using inserts coupled to piezoelectric ultrasound, without the need for biomaterials. Nine normoreactive patients in need of implant-supported rehabilitation in the posterior maxilla with hyper pneumatization of the maxillary sinuses received the SFE procedure by the transcrestal technique, using cup-type inserts dedicated to the piezoelectric ultrasound. At the end of the observation period of up to three years, one of the 15 dental implants presented early loss, and 100% success was observed in the prostheses and 93% in the implants. The patients’ complaint was restricted to a slight discomfort in the operated area, controlled with medication. The development of new inserts for piezoelectric ultrasound devices associated the safety and delicacy of ultrasound cutting with the reduced morbidity of transcrestal access for SFE.
