1. A method of preparing the installation of at least one dental implant, comprising the steps of: fixing at least one reference element (1) to at least one portion of the patient’s oral cavity, obtained by means of an optical sensor (116) or a contact probe, data related to the specified at least one area of the oral cavity； provide a first three-dimensional model of the outer surface of the specified at least one area of the oral cavity based on data related to the specified at least one area the oral cavity； obtain, by means of an X-ray scanner (118), data relating to at least one portion of the bone system of the jaw of the patient； provide a second three-dimensional model of said at least one portion of the bone system of the jaw of the patient based on data related to the at least one area of the jaw bone system； perform computer recognition of the surfaces (12, 14, 16； 42, 44, 46) of the specified at least one reference element in the first model, and these surfaces are made and x-permeable material for x-ray radiation； determine by computer means the first three-dimensional coordinate system associated with the first model； perform computer recognition of at least one section (30), the location of which is determined by x-ray radiation, the specified at least one reference element on the second models； determine by computer means a second coordinate system associated with the second model； determine by computer means the ratio conversions for1. Способ подготовки установки по меньшей мере одного зубного имплантата, содержащий этапы, на которых:фиксируют по меньшей мере один реперный элемент (1) к по меньшей мере одному участку полости рта пациента；получают, посредством оптического датчика (116) или контактного зонда, данные, относящиеся к указанному по меньшей мере одному участку полости рта；обеспечивают первую трехмерную модель наружной поверхности указанного по меньшей мере одного участка полости рта на основании данных, относящихся к указанному по меньшей
