Objective : We present a new self-drilling self-tapping dental implant that simplifies the operative technique and optimizes osseointegration.
Material and method : The implant, the instrumentation, and the operative technique are described. An experimental study was conducted in a sheep with pathological and histomorphological analysis at three months. A clinical evaluation was also conducted in 18 patients who had 27 implants.
Results : The experimental study demonstrated good quality osseointegration, without bone necrosis. Three sectors were identified. Histomorphometric analysis demonstrated that mean bone contact reached 40% on cancellous bone and 65% on cortical bone. In the clinical series, one implant had to be removed due to a problem with gum healing. All the
other implants were well tolerated.
Discussion : The advantage of this new technique is the use of the implant as the drilling instrument. Much time is saved. In addition, the bone-implant contact is better since the bone cavity is exactly adapted to the implant. The risk of bone lesion is reduced due to the smaller number of drillings.
Step 1: Drilling of the implant's pre-cavity
Step 2: Positioning of the implant
Step 3: Positioning of the cover screw
