Clinical Outcome of Implants Placed in Staged Maxillary Sinus Augmentation Using Bovine Bone Mineral Mixed with Autogenous Bone at Three Different Ratios: A 5-Year Prospective Follow-up Study

Prevalence, risk factors, and repair mechanism of different forms of sinus membrane perforations in lateral window sinus lift procedure: A retrospective cohort study

“…For this subgroup, staged procedure seems to be advantageous and should be proposed because it will allow second stage implant placement in a much safer style and additionally offers the possibility of regrafting if necessary. [5][6][7][10][11][12][13][14][32][33][34] Within the limitations of the present study, it must be mentioned that the prevalence of membrane perforation, especially microlaceration with spontaneous occlusion, may suggest a higher rate of harmless perforations. Moreover, the present investigation does neither include the evaluation of the window osteotomy technique used nor comparative measurements of maxillary sinus wall thickness and…”

Osseointegration of different implant surfaces in areas grafted with deproteinized bovine bone associated or not with fresh bone marrow—Preclinical study in rabbits

“…The use of the DBB is widely used and researched as bone substitutes due to their physicochemical properties similar to those of human bone, their osteoconductive potential, and availability (Krennmair et al, 2018;de Molon et al, 2019). However, since the DBB only has the biological properties for bone formation by osteoconduction, the waiting time for implant installation in wider sinus where the implants cannot be placed immediately associated with the sinus lift procedure is higher than the time require to place implants in areas grafted with the association of the DBB and autogenous bone graft (Jensen et al, 2012(Jensen et al, , 2013Krennmair et al, 2018). The quest to accelerate the osseointegration process in areas grafted with osteoconductive bone substitutes aims to reduce the use of autogenous bone grafts, which, despite its limitations, is still considered the gold standard in bone grafting techniques (Klijn et al, 2010;Nkenke & Neukam, 2014).…”

“…The installation of dental implants is dependent on the bone availability of the host, and it is not always possible to install the implants in a native bone area. This type of situation is especially frequent in the posterior region of the maxilla due to the presence of the maxillary sinus, which, due to a positive pressure after tooth loss, can promote the internal resorption of the alveolar bone and expansion of the sinus in the lower direction, thus reducing bone availability in that region (Krennmair et al, 2018;Pasquali et al, 2015).…”

“…Surgical techniques for elevating the maxillary sinus floor associated with the use of bone substitute biomaterials have been applied with great success rates for increasing bone availability in this region (Klijn et al, 2010;Krennmair et al, 2018;Sohn et al, 2010).…”

“…As a way to accelerate the bone healing process in areas grafted with osteoconductive bone substitutes, the association of the biomaterials with greater potential for bone tissue formation, such as autografts (Krennmair et al, 2018) and growth factors (An et al, 2019), has been applied with success. Among these alternatives, the use of fresh bone marrow (BM) stands out, which theoretically has osteogenic and osteoinductive properties due to its composition of osteochondroprogenitor stem cells and growth factors that would induce greater differentiation and osteoblastic activity (Lucarelli et al, 2004;Pasquali et al, 2015;Pelegrine et al, 2010;Wildburger et al, 2014).…”
