Segmental osteotomy with interpositional bone grafting in the posterior maxillary region

Sandwich bone graft for vertical augmentation of the posterior maxillary region: a case report with 9-year follow-up

“…The technique is relatively simple and provides satisfactory results both in terms of surgical success and predictability [15–19]. The technique is predicable because the four walls of the graft are in contact with live tissue, increasing vascularization and reducing resorption [17].…”

“…Since that first report, several reports on research outcomes, technological progress, and the good results obtained with this technique have been published. This technique is now regarded as a good way to correct vertical deficiencies prior to placement of dental implants [15–19]. …”

“…In the literature, the technique of segmental osteotomy accompanied by interpositional grafting has been reported as a practical and predictable procedure with a low incidence of complications and a high probability of success [15–19]. This approach leaves the soft tissue on the oral side of the midcrestal incision attached to the crestal bone segment.…”

“…This approach leaves the soft tissue on the oral side of the midcrestal incision attached to the crestal bone segment. Various studies have shown that alveolar osteotomy associated with interpositional grafting may be an effective alternative to other surgical techniques for increasing vertical bone height in the posterior maxilla and mandible [15–19]. The technique is based on interposing a bone graft between osteotomized bony segments, which act as a “sandwich,” offering good vasculature to both the segment and the graft and resulting in less bone resorption compared to the methods described before [15–19].…”

Repositioning Implants Through Sandwich Osteotomy with the Interposition of Lyophilized Bovine Bone

“…Nowadays, success in implantology is based on treatment that ensures long-term function, esthetics and stability (Kim et al, 2012;Nóia et al, 2012). The attainment of satisfactory results when using dental implants is completely dependent on several factors, such as adequate planning, the ideal three-dimensional position of the implant and the ability and experience of the surgeon (Bormann et al, 2011;Tavares et al, 2013;Laviv et al, 2014).…”
