[Pre-implantation evaluation using medical imagery: scanner or Scanora?].

A pre-implant investigation by way of medical imaging techniques may be effected by means of traditional X-ray clichés. However, a proper appreciation of the bone volume and the relations between the different bone structures is only possible by means of a three-dimensional evaluation. As a matter of fact, "sectional" pictures can be made by means of the "Scanner", but also by means of the "Scanora". The following article gives a detailed description of the "Scanora" technique and compares it with the "Dentascan" technique.
