Blade implants: presurgical preparation procedures and radiographical analyses

In dental implantology the selection of the implants, the design of the prosthetic appliance and the relationship between implant and occlusal antagonists are based on clinical evaluation, the study of mounted casts, as well as radiography. The simulated data from the articulator must be transferred to the oral cavity during surgery. The alveolar bone height is critical for treatment planning. Determination of the height of the alveolar process, the location of the alveolar nerve and the maxillary sinus may be based on measurements on radiographs or intra oral evaluation. A comparison study of the radiological analysis based on pantomography or free focus radiography, with actual measurements in the oral cavity was carried out in a patient. The results indicated major discrepancies between direct measurements on radiographs and those carried out clinically.
