Dental implants placement in conjunction with osteotome sinus floor elevation: a 12‐year life‐table analysis from a prospective study on 588 ITI^®implants

Abstract

Based on the results and within the limits of the present study, it can be concluded that ITI implant placement in conjunction with osteotome sinus floor elevation represents a safe modality of treating the posterior maxilla in areas with reduced bone height subjacent to the sinus as survival and success rates were maintained above 90% for a mean observation period of approximately 60 months. Shorter implants (8 mm implants) did not significantly fail more than longer ones (10 and 12 mm implants): the differences were small compared with the number of events; hence, no statistical conclusion could be drawn. But, from the clinical point of view, the predictable use of short implants in conjunction with osteotome sinus floor elevation may reduce the indication for complex invasive procedures like sinus lift and bone grafting procedures.

Efetividade das técnicas de levantamento sinusal atraumático

“…Um estudo para avaliar o sucesso clínico da colocação de implantes ITI (Straumann, Basel, Suíça) na maxila posterior, colocados com a técnica do osteóto-mo associada a enxertos foi realizada por Ferrigno et al (17). Esse estudo com 12 anos de duração englobou 323 pacientes O período médio de observação foi 59.7…”

Levantamiento del piso de seno maxilar mediante la técnica de osteótomos

“…La zona edéntula posterior de la maxila generalmente proporciona una cantidad limitada de volumen óseo debido a una atrofia del reborde y la neumatización del seno maxilar, estas limitaciones anatómicas representan desafíos que pueden afectar el éxito de la oseointegración y la confección de una restauración implantosoportada funcional y esté-tica (1).…”
