Reconstruction of maxillary defects with free fibula flap assisted by computer techniques

Novel approach to maxillary reconstruction using osteocutaneous free tissue transfer with a customized stent

“…Several studies have shown that the use of 3D modelling can decrease ischemia time, total operative time, and even reduce the cost because of decreased operative time . A study by Modabber et al showed that mean ischemia times for fibular flaps using traditional methods was 131.2 minutes compared to 104.8 minutes using 3D modelling . We have found similar benefits to modelling in our maxillary reconstruction cases compared to no modelling.…”

“…5,12 A study by Modabber et al 5 showed that mean ischemia times for fibular flaps using traditional methods was 131.2 minutes compared to 104.8 minutes using 3D modelling. 13 We have found similar benefits to modelling in our maxillary reconstruction cases compared to no modelling. We have found the stent technique is not much different in terms of time compared to 3D modelling with cutting guides and pre-bent plates.…”

Osseointegration effect of biomimetic intrafibrillarly mineralized collagen applied simultaneously with titanium implant: A pilot in vivo study

“…Jawbone defect reconstruction that restores bone continuity and allows for dental rehabilitation remains a challenge for surgeons (Shen et al, ; Shnayder et al, ; Zhang et al, ). The achievement and maintenance of implant osseointegration in a predictable way is one of the most important aspects for successful use of implants to repair jawbone defects.…”

“…Jawbone defects can result from trauma, osteomyelitis, tumor resection, or a congenital malformation and can create significant facial deformities that affect patients’ quality of life and cause a socioeconomic burden (Mizukami, Hyodo, Fukamizu, & Mineta, ; Shnayder et al, ; von Wilmowsky et al, ). Because jawbone defects are often accompanied by the loss of teeth, the objectives of jawbone reconstruction include not only restoring the anatomical height and contour of the missing part, but also achieving the maximum possible functionality for dental rehabilitation, which poses a great challenge for surgeons (Shen et al, ; Shnayder et al, ; Zhang et al, ). In past decades, methods using vascularized or non‐vascularized free flaps with simultaneous or delayed implant placement for jawbone defect reconstruction have been developed as a standard treatment modality (Chang, Coskunfirat, Wei, Tsai, & Lin, ; Pauchet, Pigot, Chabolle, & Bach, ; Shen et al, ; Shnayder et al, ).…”

Intraoperative Change in Defect Size during Maxillary Reconstruction Using Surgical Guides Created by CAD/CAM

“…Using CAD/CAM guides allows the surgeon to cut the fibula accurately and to perform an accurate reconstruction. 3,4 Because the deviation between the postoperative and preoperative 3D images was only 2–4 mm, we considered that the reconstruction was accurate.…”
