The effect of anatomy on osteogenesis after maxillary sinus floor augmentation: a radiographic and histological analysis

Does new bone formation vary in different sites within the same maxillary sinus after lateral augmentation? A prospective histomorphometric study

“…Sinus bucco-palatal width (SW) and %NFMT showed a strong negative correlation, in agreement with numerous previous studies (Avila et al, 2010;Kolerman et al, 2008;Lombardi et al, 2017;Soardi et al, 2011;Stacchi et al, 2018;Zhou et al, 2021) but in disagreement with a recent article (Pignaton et al, 2019). This difference could be explained by methodological differences between the two studies (grafting material, healing time and method for clustering sinus width) and possible patient-related variables (which are absent in the present study, as mesial and distal biopsies were harvested from the same sinus).…”

“…No correlation was demonstrated between RBH and %NFMT: this outcome is consistent with many other studies demonstrating that graft remodelling into new bone was not significantly influenced by residual alveolar bone height (Avila et al, 2010;Pesce et al, 2021;Pignaton et al, 2019;Stacchi et al, 2018;Taschieri et al, 2020;Zhou et al, 2021). From which does not give information about possible further graft consolidation in longer healing periods, as showed in other studies (Soardi et al, 2011).…”

“…No correlation was demonstrated between RBH and %NFMT: this outcome is consistent with many other studies demonstrating that graft remodelling into new bone was not significantly influenced by residual alveolar bone height (Avila et al, 2010 ; Avila‐Ortiz, Neiva, et al, 2012 ; Pesce et al, 2021 ; Pignaton et al, 2019 ; Stacchi et al, 2018 ; Taschieri et al, 2020 ; Zhou et al, 2021 ). From these findings, RBH should not be considered as a possible indicator of the regenerative potential of the site to be augmented, but only as a predictive factor for immediate implant placement (Stacchi et al, 2020 ).…”

Intraoperative complications and early implant failure after transcrestal sinus floor elevation with residual bone height ≤5 mm: A retrospective multicenter study

“…In the present study, bucco‐palatal maxillary sinus width seems to play a crucial role in the success of implant rehabilitations: wide sinus cavities (>12 mm at 10‐mm height, comprising the alveolar crest) resulted significantly associated with early implant failure. A wide sinus cavity has been shown by numerous studies to represent a biologically unfavorable environment for new bone formation after both lateral and crestal sinus lift (Avila et al, 2010; Kolerman et al, 2008; Lombardi et al, 2017; Soardi et al, 2011; Stacchi et al, 2018; Stacchi et al, 2022; Zhou et al, 2021). This situation is a consequence of the increased distance between the central part of the regeneration area (where the implant is usually inserted) and the bony walls, which are the primary source of osteoprogenitor cells and blood supply (Dragonas et al, 2020).…”
