Cerec meets Galileos--integrated implantology for completely virtual implant planning.

The greatest key to successful implant therapy is proper placement of the implant in the jaw bone. The key to proper placement is careful preoperative planning. When planning implant treatment, it is important to take the relevant anatomical features and their later prosthetic consequences into account.

Accuracy of chairside-milled CAD/CAM drill guides for dental implants.

Purpose: To describe a chairside method for producing implant guides based solely on digital data and present a first assessment of in vitro accuracy on plaster models.

Material And Methods: Twenty-four implants were planned and pilot drillings were performed according to a new protocol, which is based on the registration of CBCT and CAD/CAM data. Chairside-milled one-piece drill guides were used to transfer the virtual plan into reality.

Registration accuracy of three-dimensional surface and cone beam computed tomography data for virtual implant planning.

Objective: Virtual wax-ups based on three-dimensional (3D) surface models can be matched (i.e. registered) to cone beam computed tomography (CBCT) data of the same patient for dental implant planning.

Comparison of torque measurements and clinical handling of various surgical motors.

Purpose: Modern implant dentistry requires the application of torque during various treatment steps. This study investigated seven different surgical motors for the accuracy of the applied torque and their reliability.

Materials And Methods: The following surgical motors were evaluated: Chiropro 980 (Bienair), INTRAsurg 300 and INTRAsurg 500 (KaVo), Osseocare (Nobel Biocare), Surgic XT (NSK), Elcomed SA-200 C (W and H), and Osseo System (XO Dentalcare).

Application of a computer navigation system for the placement of orthodontic anchorage screws.

The computer navigation system Robodent, which was developed for dental implants, was used for the placement of orthodontic anchorage screws in a phantom head. The deviation between the planned and finally achieved position of the screws did not exceed that reported for dental implants. In conclusion, the system seem to be suitable and precise enough for orthodontic screws.
