In the radiographic examination, by means of panoramic radiography and/or CT scans, the bone volume of the area where implants are to be placed is studied.

Patients lacking enough bone crest volume for the correct placement of implants must be properly examined to use bone regeneration and widening techniques.

These studies allow to analyze the possibilities of implant placement, the expected stability of the implants, regarding the amount, length, diameter of the implants and hardness of the bone in which they will be fixed, as well as the features of the selected prosthesis.

It is important to construct study models in order to calculate the necessary prosthetic space for the prosthodontic components and to make a surgical-radiographic template to mesure precisely both bone height and optimal position and direction of the implants, which will be of great help in the surgical stage.

Once the optimal axis of the implant or implants to be placed is chosen, diameter and length must be selected, with the help of KLOCKNER® templates, which are prepared to superimpose on orthopantomographies, regarding their magnification. [25%] These templates must be used only as a guide since radiographic techniques such as CT scans must be used when more exact measures are required.
During the planning process, it is necessary to analyze the weft density in order to see the bone quality.

It is very important to bear in mind that in order to guarantee the stability of the bone around the implant without resorption occurring, the surrounding bone should be at least 1.5 mm thick in all sides in order to keep minimal vascularization. This will keep the bone around the implant vital at crestal level.
