Resumo: |
Implant angular deviation during guided surgery can be obtained by image interpolation on appropriate software. However, real time measurement can also be made on a 3-D way. The aim of this study was to evaluate the angular deviation using dental plaster casts as physical references. Five patients were enrolled. After reverse treatment planning, 0.4mm-thick slices were obtained by CT scanning. (Toshiba Xvision), using the Procera NobelGuide software for virtual implant positioning. Then, with the surgical guides, implant replicas were connected to generate plaster model A. On surgery, Brånemark NobelSpeedy implants (4 mmdiameter x 11.5 mm-18 mm-length) were placed. An impression was made at the platform levels to generate plaster model B. All defi nitive prostheses were delivered after 12 hours. A CCM (Tesa Micro-Hite 3D, Swiss) was used to measure implant angulation in X, Y and Z planes. The angular deviation (!Z, absolute difference between models A and B) for each implant was generated in degrees, minutes and seconds. Mean angular deviation registered for all implants was approximately 0.82 ± 0.71 degrees (range of 0-4.13 degrees). The obtained values were within reported numbers in the literature. This measurement protocol is reliable and brings about new study possibilities. |
