ProPlan CMF (Depuy Synthes, Solothurn, Switzerland, and Materialise, Leuven, Belgium) is a computer-aided surgical virtual planning service using an online meeting with professional medical engineers and transfers patient-specific surgical guide to the virtual plan. Moreover, prebent reconstruction plates or patient-specific computer-aided manufacturing-fabricated reconstruction can also be used. This service started in 2011. Currently, it is widely used in Europe. Current status of mandibular reconstruction with ProPlan CMF vertical planning service with the surgical guide was reviewed. The accuracy was excellent in terms of contact of the osteotomized parts and the contact to the remaining skeleton. The authors found that currently, a small number of reports regarding the mandibular reconstruction with virtual planning service and surgical guides are available. These reports also have a small number of cases and short-term follow-up results. In this situation, this review revealed that (1) mainly the resection guides, cutting guides, and patient-specific mandible reconstruction plates were adequately well fitted to the surgical site intraoperatively, (2) the ischemic time might be more reduced than that of the conventional surgery (3) the accuracy of computer-assisted surgery in the mandibular reconstruction was clinically acceptable, and (4) condyle positions after the computer-assisted surgery was mainly normal. The higher additional cost than that of the conventional technique is presently an issue. Large-scale clinical studies and long-term follow-up studies are demanded.

Summary Aim: Determination of the range of regional blood flow and fluoride influx during normal incorporation of revascularized fibula grafts used for mandibular reconstruction. Evaluation, if healing complications are preceded by typical deviations of these parameters from the normal range. Assessment of the potential influence of using “scaled population-derived” instead of “individually measured” input functions in quantitative analysis. Methods: Dynamic F-l 8-PET images and arterialized venous blood samples were obtained in 11 patients early and late after surgery. Based on kinetic modeling regional blood flow (K1) and fluoride influx (Kmlf) were determined. Results: In uncomplicated cases, early postoperative graft K1 - but not Kmlf -exceeded that of vertebrae as reference region. Kmn values obtained in graft necrosis (n = 2) were below the ranges of values observed in uncomplicated healing (0.01 13-0.0745 ml/min/ml) as well as that of the reference region (0.0154-0.0748). Knf values in mobile non-union were in the lower range - and those in rigid non-union in the upper range of values obtained in stable union (0.021 1-0.0694). If scaled population-derived instead of measured input functions were used for quantification, mean deviations of 23 ± 17% in K1 and 12 ± 16% in Kmlf were observed. Conclusions: Normal healing of predominantly cortical bone transplants is characterized by relatively low osteoblastic activity together with increased perfusion. It may be anticipated that transplant necrosis can be identified by showing markedly reduced F− influx. In case that measured input functions are not available, quantification with scaled population-derived input functions is appropriate if expected differences in quantitative parameters exceed 70%.

Dental surgeons need in-depth knowledge of the bone tissue status and gingival morphology of atrophic maxillae. The aim of this study is to describe preoperative virtual planning of placement of five implants and to compare the plan with the actual surgical results. Three-dimensional planning of rehabilitation using software programs enables surgical guides to be specially designed for the implant site and manufactured using 3D printing. A patient with five teeth missing was selected for this study. The patient’s maxillary region was scanned with CBCT and a cast model was produced. After virtual planning using ImplantViewer, five implants were placed using a printed surgical guide. Two weeks after the surgical procedure, the patient underwent another CBCT scan of the maxilla. Statistically significant differences were detected between the virtually planned positions and the actual positions of the implants, with a mean deviation of 0.36 mm in the cervical region and 0.7 mm in the apical region. The surgical technique used enables more accurate procedures when compared to the conventional technique. Implants can be better positioned, with a high level of predictability, reducing both operating time and patient discomfort.
