Abstract

The aim of the present study was to histologically analyse the bone graft-titanium implant interface after six and twelve months of healing for a simultaneous approach and after six months for a delayed approach. For this purpose, screw-shaped c.p. titanium microimplants, 2 mm in diameter and 5 mm long, were placed and retrieved at different time intervals in ten consecutive patients with severely resorbed maxillae and treated with iliac cortico-cancellous bone grafts and titanium implants in a two-stage procedure. The histomorphometrical analyses of ground sections of the specimens showed a higher degree of bone-implant contact and more bone filling the implant threads in the delayed approach microimplants. This was probably due to the partly revascularized grafted bone in the delayed approach being able to respond to the surgical trauma, resulting in interfacial bone formation. It is concluded that the results from the present study favour the use of a delayed approach when using free autogenous bone grafts and titanium implants for reconstruction of the severely atrophied maxilla.

      When the implants are removed in these situations, horizontal bone deficiency is present. Classic bone grafting studies11-14 indicate that bone grafts require the availability of blood vessels to revascularize the graft and result in bone formation. This requires intact soft tissue to cover the bone graft, which is placed onto the resorbed ridge.

      Severe atrophy of maxilla and mandible can be treated successfully with various augmentation procedures in combination with dental implant systems (Vermeeren et al., 1996; Reinert et al., 2003; Whitmyer et al.; 2003; Nelson et al., 2006a,b). In patients with minimal residual bone, autogenous bone from the iliac crest remains the gold standard, providing the properties necessary for bone remodeling: osteoinduction, osteoconduction, and osteogenic potential (Lundgren et al., 1999; van der Meij et al., 2005; Chiapasco et al., 2007; Moses et al., 2007; Sbordone et al.; 2014). The authors showed an implant survival rate up to 98.7% within a 5-year period after iliac crest onlay grafting in the mandible (Boven et al., 2014).

      To date, various nonvascularised augmentation materials such as alloplastic grafts (Köndell et al., 1996), xenografts (Yildirim et al., 2000), autogenous grafts (Lekholm et al., 1999), and combinations (Hatano et al., 2004) have been evaluated. In cases with severe atrophies autogenous bone became prevalent as the medical “gold standard” for augmentation procedures (Lundgren et al., 1999; Reinert et al., 2003; Schliephake et al., 1999b). The iliac crest, with a large amount of bone available, is a widely accepted donor site irrespective of reported resorption rates of up to 50 % of the initial height (Balshi et al., 2003; Bell et al., 2002).

      Using a two-stage surgery protocol, Sjöström et al. (2007) reported 90% survival rate of machined dental implants after 3 years of follow up. Using machined endosteal implants (Brånemark® System, Nobel Biocare AB, Göteborg, Sweden), Lundgren et al. (1999) presented higher degree bone to implant contact and more bone area filling the threads in a delayed approach when comparing one and two-stage surgery. Thus, it can be concluded from the literature that a two-stage surgery protocol enhances the prognosis of implant survival rate.
