A prospective study of factors influencing morbidity after iliac crest harvesting for oral onlay grafting

Horizontal bone grafting using equine‐derived cancellous bone blocks is associated with severe complications: A prospective clinical and histological pilot study

“…A graft failure rate of 60% as demonstrated in the present study is unacceptable in daily clinics, as alveolar reconstruction using particulate bovine bone and autologous bone as block or shield demonstrates low complication rates and long‐term stability (Fretwurst, Nack, et al, 2015; Fretwurst, Wanner, et al, 2015; Troeltzsch et al., 2016). Since no soft tissue dehiscences occurred in the present study, possible graft failure mechanisms could be attributed to insufficient graft incorporation/remodeling due to a low transplant competence (poor osteoconductive properties), graft infection after implant placement and/or remaining equine cell and protein content with a possible corresponding immunogenic potential.…”

“…In atrophic jaws, vertical and horizontal bone grafting procedures are required prior to implant placement to enable an adequate three‐dimensional implant position (Sanz & Vignoletti, 2015). Autologous bone is still considered to be the gold standard in alveolar defects > 5 mm because of its transplant competence, mainly used as block grafts (Fretwurst, Gad, Nelson, & Schmelzeisen, 2015; Fretwurst, Nack, et al, 2015; Fretwurst, Wanner, et al, 2015; Jensen & Terheyden, 2009; Sanz‐Sanchez, Ortiz‐Vigon, Sanz‐Martin, Figuero, & Sanz, 2015). However, a disadvantage is the associated donor site morbidity (Cordaro, Torsello, Miuccio, di Torresanto, & Eliopoulos, 2011; Cremonini, Dumas, Pannuti, Lima, & Cavalcanti, 2010; Fretwurst, Nack, et al, 2015; Fretwurst, Wanner, et al, 2015; Nkenke et al., 2002; Nkenke, Schultze‐Mosgau, Radespiel‐Troger, Kloss, & Neukam, 2001).…”

Vitamin D deficiency in early implant failure: two case reports

“…In the augmentation procedure, a crestal incision in the attached gingiva of the edentulous alveolar crest with one vertical releasing incision was used, after mobilization of the mucoperiosteal flap an autologous retromolar bone block was fixed on the occlusal part of the alveolar ridge. The bone block was secured with a microscrew (Modus 1.5, Medartis, Umkirch, Germany) and covered with a resorbable membrane (BioGide, Geistlich AG, Switzerland) as described previously [29]. The passively mobilized mucosa was closed with a running suture and secured with interrupted sutures (5-0 Monocryl, Ethicon, Norderstedt, Germany).…”

Biomechanical evaluation of one-piece and two-piece small-diameter dental implants: In-vitro experimental and three-dimensional finite element analyses

“…Especially for autogenous bone grafting, many complications including paraesthesia and morbidity of the donor site have been reported. 1 Nevertheless, the use of small-diameter implants has to be considered along with their potential limitations. From a biomechanical aspect, small-diameter implants are structurally weaker than standard-size implants (3.75e4 mm in diameter).…”
