“…Em nosso estudo, um valor comparável foi calculado para ganho ósseo apical após um período de observação de 4 anos. Uma revisão diferente [ 17 ], no entanto, relatou variação no ganho ósseo vertical entre 1,7 mm e 4,1 mm em grupos sem enxerto após 3 anos. Com base nos achados do nosso estudo, a variação no ganho ósseo vertical foi predominantemente afetada pela quantidade de altura óssea residual.…”

Fundo: Avaliar as alterações na altura óssea apical / ganho ósseo por até 8 anos após a colocação do implante combinada com elevação simultânea do seio interno do assoalho do seio (ISFE) sem o uso de enxerto. Métodos: 217 implantes foram colocados em combinação com ISFE sem enxerto e integrados com sucesso na maxila posterior de 138 pacientes. As radiografias após a cirurgia ao longo de um período de avaliação de até 8 anos foram analisadas. Alterações na altura óssea apical e marginal relacionadas aos implantes foram medidas. As diferenças na altura óssea ao longo do período do estudo foram avaliadas pelo teste de Wilcoxon. Para identificar possíveis fatores de influência no ganho ósseo apical e perda óssea marginal, foram realizadas seleções de regressão linear regressiva e modelos de regressão linear mista. Resultados: Nos aspectos apicais dos implantes, observou-se ganho ósseo vertical médio significativo de 2,4 mm (mesial) e 2,6 mm (distal) após 6 meses ( p < 0,05). A análise radiográfica produziu ganho ósseo adicional de até aproximadamente 3,5 mm durante o período do estudo. A altura óssea inicial pequena foi cruzada com ganho ósseo apical mais pronunciado ( p < 0,05). Conclusões: Se os implantes forem colocados combinados com o ISFE sem enxerto, pode-se esperar um ganho ósseo vertical significativo, especialmente no primeiro ano pós-operatório. Menor altura óssea inicial está associada a uma maior probabilidade de maior ganho ósseo.

“…No entanto, aqui o período de observação foi bastante curto, com 17 meses de acompanhamento. Com relação ao prognóstico do implante, os autores deste estudo também relataram que alturas ósseas residuais inferiores a 4 mm e perfurações na membrana reduzem a probabilidade de sobrevida em 10 anos [ 17 ].…”

“…However, here the observation period was rather short with 17-months follow-up. With regard to implant prognosis, the authors of this study also reported that residual bone heights lower than 4 mm and membrane perforations reduce the probability of 10-year survival [ 17 ].…”

Background To assess changes in apical bone height/bone gain over up to 8 years after implant placement combined with simultaneous internal sinus-floor elevation (ISFE) without use of graft. Methods 217 implants were placed in combination with graft-free ISFE and successfully healed in the posterior maxilla of 138 patients. Radiographs after surgery across an evaluation time of up to 8 years were analyzed. Changes in apical and marginal bone height related to the implants were measured. Differences in bone height over the study period were evaluated by use of Wilcoxon tests. To identify possible influencing factors on apical bone gain and marginal bone loss, backward linear regression variable selections and linear mixed regression models were performed. Results At the apical aspects of the implants, significant mean vertical bone gain of 2.4 mm (mesial) and 2.6 mm (distal) was observed after 6 months ( p < 0.05). Radiographic analysis yielded additional bone gain of up to approximately 3.5 mm over the study period. Small initial bone height was crossed with more pronounced apical bone gain ( p < 0.05). Conclusions If implants are placed combined with graft-free ISFE, significant vertical bone gain, especially in the first year post-op, can be expected. Smaller initial bone height is associated with a higher likelihood for greater bone gain.

“…Several studies point to long-term (over 10 years) predictability of OSFE without grafting (Caban et al, 2017;Fugazzotto, 2017;Nedir et al, 2016;Rammelsberg et al, 2020). In a retrospective study, 22 implants have been followed for 10 years.…”

Objective: The aim of the present study was to report 10-year results of osteotome sinus floor elevation (OSFE) without grafting severely atrophic maxilla (residual bone height ≤4 mm). Materials and Methods: Patients undergoing OSFE without grafting and implant placement were included for 10-year examinations. Implant survival, complicationfree survival, modified bleeding index (mBI), modified plaque index (mPI), pocket probing depth (PPD), peri-implant marginal bone loss (MBL), endo-sinus bone gain (ESBG) and mean cost of recurrence were evaluated. Results: Overall, 23 patients with 35 implants attended 10-year examination. Cemented implant crowns or implant-supported fixed dental prostheses were delivered to the patients. Kaplan-Meier implant survival was 89.2% at implant level and 84.1% at patient level. Complication-free survival was 26.0% at patient level and 37.0% at implant level. The average complication-free survival time was 74.6 months (95% CI: 63.2-86.0 months) at implant level and 69.1 months (95% CI: 54.8-83.4 months) at patient level. The mBI, mPI, PPD, MBL and ESBG at 10-year follow-up were 0.91 ± 0.58, 0.48 ± 0.51, 2.94 ± 0.79 mm, 1.63 ± 0.83 mm and 2.72 ± 0.51 mm, respectively. The cost of managing recurrence was 43.6% of the initial cost of treatment. Conclusion: The results of the present study indicate that OSFE without grafting is a reliable treatment option in severely atrophic maxilla. Acceptable survival rate, stable MBL and ESBG could be achieved within 10 years. Low complication-free survival and high costs of recurrence management need to be considered.
