State of art

Several options are available for dental implant treatment planning. These range from CBCT to implant planning software based on 3D images. The most relevant features of these approaches are summarised below:

CBCT 3D printing of surgical guide, PR, FP core Mock up and handmade surgical guide Implant planning software
Definition X-ray CT where rays are divergent 3D denture from a CAD model Hand-modelling of a wax restoration and an acrylic surgical guide Computational 3D tools for visual implant simulation
Equipment Radiology scan, usually Intra-oral 3D scanners, lab scanners, 3D printers Dental office and dental laboratory standard equipment Computer and software license
Strength 3D reconstruction of all soft and hard tissues 3D mesh of intra-oral visible soft-tissues Aesthetic simulation. Patients’ agreement based on FP contour 3D visual simulation of the implant procedure
Limitations No real-life colours Difficult to separate No reliable integration with CBCT Operator-dependent Graphical info, no data about biomechanics

These tools are useful for implant treatment planning, but they lack key information about mechanical stress and deformations within oral cavity structures after implant placement. Biomechanical optimisation won’t be achieved by the use of the state of the art tools, hence, failure likelihood increases. There are also other approaches to obtain this mechanical information like photoelasticity or strain gauge measurements, but both require the set-up of a complex and time consuming experiment. Thus, they are not useful to be applied on a daily basis
