Facilitate treatment is a new approach to implant placing, allowing to plan and perform a predictable implant treatment. This system consists of a series of instruments for guided implant placement through the use of a surgical stent and special drills.

Position, inclination and installation depth can be guided, as well as implant insertion.
The surgical stent can have a mucosal, dental or bone support according to the clinical needs. It is built through a stereolithographic model, from which we can obtain a master model and build our provisional to perform immediate loading.

AIMS
The aim of the present study is to discuss the role of CAD-CAM technology and stereolithography, which closely depend on interactive CT scan for preoperative implant evaluation, and the level of predictable outcome in terms of function and esthetics.

MATERIALS AND METHODS
The Authors analyzed the advantages and disadvantages of the two techniques on a group of 12 patients, 3 with upper and lower total edentulism, 5 with upper and lower partial edentulism, 2 with upper monoedentulism and 2 with lower monoedentulism. A total of 69 implants were inserted, 40 in the upper jaw and 29 in the lower jaw.

RESULTS
1, 3, 6 and 12 month clinical follow-up and 1, 6 and 12 month radiological follow-up of all 12 patients did not reveal any sign of inflammation and bone resorption.

Six months after implant insertion, most implants were osseointegrated. 2 out of 69 implants with facilitate system failed 6 months later, which were placed in the upper jaw of the same patient. The 12-month implant success rate was 97%.

CONCLUSIONS
An advanced software, CAD/CAM technology and stereolithography are crucial for preoperative implant evaluation. A complete knowledge on the quality and quantity of bone makes it possible to determine the best implant placement, which is achieved with the help of surgical stents.

This will increase the chances for implant success.
