US 2017/0304005 A1 · SURGICAL TEMPLATE FOR DENTAL AND/OR ORTHODONTIC IMPLANTS AND METHOD FOR DESIGNING A SURGICAL TEMPLATE

Abstract

A computer-aided method for designing a surgical template for dental and/or orthodontic implants comprises acquiring a first 2D or 3D image of the oral cavity and of the overlying anatomical structures of a patient, processing the first image for defining one or more second 2D images showing corresponding views or sections of the oral cavity, realizing a digital model of the upper dental arch and of the palate of the patient to identify one or more suitable sites for inserting a corresponding implant, selecting one or more slices of the digital model at one or more sagittal or parasagittal planes passing through respective insertion sites, overlapping the slices with corresponding second 2D images for generating a third 2D image, providing a digital library of implants for the selection thereof and for their virtual positioning into the third image in order to allow the adjustment of the inclination and/or the deepness of insertion. A surgical template for dental and/or orthodontic implants suitable to be manufactured with the above method.

Dependent claims

A computer-aided method for designing a surgical template for dental and/or orthodontic implants, characterized by comprising the following steps:

a) acquiring a first 2D or 3D image of the oral cavity and of the overlying anatomical structures of a patient;
b) processing said first image for defining one or more second 2D images showing corresponding views or sections of the oral cavity with respect to a sagittal plane;
c) realizing a digital model of the upper dental arch and of the palate of the patient and identifying one or more suitable sites for inserting a corresponding implant;
d) selecting one or more slices of said digital model at one or more sagittal or parasagittal planes passing through respective of said one or more insertion sites previously identified;
e) overlapping said one or more slices with corresponding second 2D images for generating a third 2D image;
f) providing a digital library of implants;
g) selecting the implants from said library;
h) virtual positioning of said implants into said third image;
i) adjusting the inclination and/or the deepness of insertion of said virtual implants.

6 more elements

A surgical template (1) for dental and/or orthodontic implants, in particular palatal implants, manufactured according to a method as claimed in one or more of the preceding claims, comprising:

a palate portion (2) reproducing the shape of the palate of a patient;
at least one substantially cylindrical guide (5) provided in said palate portion (2) and having an axial passage (6) with an inlet section (7) and an outlet section (8) for the insertion of a corresponding implant in the palate of the patient with predetermined inclination and deepness;
characterized in that said at least one guide (5) has end-stroke means (11) adapted to define an axial abutment for the implant (9) at the insertion thereof into said passage (6) for adjusting the insertion deepness.
