“…Our results are also comparable with those for other registration methods such as laser surface scanning, boneimplanted fiduciary markers, and anatomical structures (Schlaier et al, 2002;Marmulla et al, 2004a;Hoffmann et al, 2005b;Hardy et al, 2006;Pham et al, 2007). The use of a CBCT dataset seems to lead to the same results as those obtained with a CT dataset (Eggers et al, 2009).…”

“…Although the pointer was placed exactly on the landmarks, the navigation system recorded a fixed deviation, thus depicting the pointer head next to the landmark. The navigation software computes the target registration error (Fitzpatrick and West, 2001;Marmulla et al, 2004a) as the square root of the sum of squared deviation in all three spatial directions is � Δ 2 + Δ 2 + Δ 2 . This deviation was recorded for each landmark and registration method.…”

“…Several methods have been used to solve the registration problem. They can be split into two groups: markerbased registration (Altobelli et al, 1993;Hassfeld et al, 1995;Howard et al, 1995;Schramm et al, 1999;Luebbers et al, 2008) and marker-free registration (Troitzsch et al, 2003;Marmulla et al, 2004a;Hoffmann et al, 2005b;Marmulla et al, 2005;Luebbers et al, 2008).…”

“…Previous studies have evaluated general precision (Schlaier et al, 2002;Hoffmann et al, 2005b;Metzger et al, 2007) and concentrated on navigation precision in the maxillary and periorbital region (Marmulla et al, 2004b;Marmulla et al, 2004a;Hardy et al, 2006) or precision in the cranium (Luebbers et al, 2008).…”

INTRODUCTION:Computer navigation plays an increasingly important role in craniomaxillofacial surgery. The difficulties in computer navigation at the craniomaxillofacial site lie in the accurate transmission of the dataset to the operating room. This study investigates the accuracy of the dental-splint registration method for the skull, midface, and mandible. MATERIAL AND METHODS: A synthetic human skull model was prepared with landmarks and scanned with cone beam computer tomography (CBCT). Two registration splints fixed the mandible against the viscerocranium in two different positions (closed vs. open). The target registration error was computed in all 278 landmarks spread over the entire skull and mandible in 10 repeated measurements using the VectorVision(2) (Brain-LAB Inc., Feldkirchen, Germany) navigation system. RESULTS: If registered in the closed position an average precision of 2.07mm with a standard deviation (SD) of 0.78mm was computed for all landmarks distributed over the whole skull. Registration in the open position resulted in an average precision of 1.53mm (SD=0.55mm). For single landmarks the precision decreases linearly with distance from the reference markers. The longer the three-dimensional distance between the registration points, the more precise the computer navigation is, mainly in the most posterior area of the cranium. CONCLUSION: Our findings in the cranium are comparable with those of other studies. Artificial fixation of the lower jaw via splint seems to introduce no additional error. The registration points should be as far apart from each other as possible during navigation with the splint.

“…In the previous investigations, a high-resolution laser scanner was utilized to perform surface registration in the clinical setting (Marmulla et al, 2003;Marmulla et al, 2004). A good registration result was achieved which was up to 1.1 ± 0.28 mm.…”

INTRODUCTION:Perioperative navigation is a recent addition to orthognathic surgery. This study aimed to evaluate the accuracy of anatomical landmarks-based registration. MATERIALS AND METHODS: Eighty-five holes (1.2 mm diameter) were drilled in the surface of a plastic skull model, which was then scanned using a SkyView cone beam computed tomography scanner. DICOM files were imported into BrainLab ENT 3.0.0 to make a surgical plan. Six anatomical points were selected for registration: the infraorbital foramena, the anterior nasal spine, the crown tips of the upper canines, and the mesial contact point of the upper incisors. Each registration was performed five times by two separate observers (10 times total). RESULTS: The mean target registration error (TRE) in the anterior maxillary/zygomatic region was 0.93 ± 0.31 mm (p < 0.001 compared with other anatomical regions). The only statistically significant inter-observer difference of mean TRE was at the zygomatic arch, but was not clinically relevant. CONCLUSION: With six anatomical landmarks used, the mean TRE was clinically acceptable in the maxillary/zygomatic region. This registration technique may be used to access occlusal changes during bimaxillary surgery, but should be used with caution in other anatomical regions of the skull because of the large TRE observed.
