A New Transalveolar Sinus Lift Procedure for Single Implant Placement: The Ebanist Technique. A Technical Description and Case Series

Abstract

Background:Nowadays, there are many techniques to compensate bone atrophies of the posterior maxilla in order to obtain an implant-supported rehabilitation.Objective:This case series describes the Ebanist technique: a sinus lift procedure to be used in case of extremely resorbed bone crests (≤3 mm) allowing simultaneous implant placement.Methods:With a dedicated cylindrical trephine bur, it is possible to harvest a cylinder of bone from a fresh mineralized frozen homologous bone block graft and to simultaneously create a trapdoor on the recipient site. The trapdoor cortical bone is detached from the sinus membrane and removed. Dental implant is placed into the graft before the grafting procedure since the cylindrical block, once inserted in the recipient area, is not able to oppose sufficient resistance to the torque needed for implant placement.Results:Second-stage surgery and following prosthetic rehabilitation were performed after 5 months. In all cases, implant stability was manually checked and no pathological symptoms or signs were recovered at any follow-up visit.Conclusion:This technique can be considered a valid procedure for implant therapy on atrophic posterior upper maxillae, when the residual bone crest is extremely resorbed.

Colocación de Implante Dental con Elevación Atraumática del Piso de Seno Maxilar: Reporte de Caso

“…La elevación del piso de seno maxilar es un procedimiento predecible para compensar la pérdida ósea a través de diferentes técnicas, métodos de acceso y biomateriales, sin embargo, la limitación principal aparece en crestas óseas extremadamente reabsorbidas (≤3 mm) (Rizzo et al, 2017). Incluso en situaciones de alturas óseas ≤ 2 mm; existe un abordaje modificado con acceso de ventana crestal; para desprender la membrana sinusal e injertar biomaterial (Soardi et al, 2020).…”

Efficacy of bone ring grafts for the reconstruction of alveolar ridge deficiencies: A systematic review. Part I: Clinical trials

“…The citation search located 5 additional articles. [6,8,[21][22][23] Out of a total of 147 articles, 43 duplicate articles were discarded. After conducting title and abstract screening as well as citation search, the full text of 19 articles was reviewed.…”

“…Following the exclusion of 5 articles (Table 2), a total of 14 articles were ultimately included for inclusion in this systematic review. [6,8,[21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] Figure 2 illustrates the search and screening process.…”

“…The 14 articles included 6 case series, [6,22,[27][28][29]32] 3 retrospective CSs, [8,23,30] 3 prospective CSs, [21,34,35] and 2 CCTs. [31,33] All studies were published between 2000 and 2023, and the mean follow-up period ranged from 4 months to 3.1 years.…”
