Bone Augmentation in Dental Implantology Using Press-Fit Bone Cylinders and Twin-Principle Diamond Hollow Drills: A Case Series
2009
Background: Bone transplants are mostly prepared with cutting drills, chisels, and rasps. These techniques are difficult for unexperienced surgeons, and the implant interface is less precise due to unstandardized preparation. Cylindrical bone transplants are a known alternative. Current techniques include fixation methods with osteosynthesis screws or the dental implant. Purpose: A new bone cylinder transplant technique is presented using a twin-drill principle resulting in a customized pressfit of the transplant without fixation devices and combining this with the superior grinding properties of a diamond coating. Materials and Methods: New cylindrical diamond hollow drills are used for cu…
Evaluation of ergonomics and efficacy of instruments in dentistry
2013
Abstract: Purpose: To evaluate the ergonomics and efficacy of five instruments used in dentistry for scaling and root planing. Methods: This experimental study with a comparative cross-sectional design was carried out during a simulated scaling and root planing task. Seven female dentists and one dental hygienist aged 26–58 years participated. Five instruments were evaluated in a subjective analysis of usability and musculoskeletal strain and with measurements of muscular activity, postures of the upper limbs, and work productivity. Results: The instruments with the thickest (diameter of 12–14 mm) silicon handles caused the lowest perceived strain in both the fingers/palm and the thumb. Wor…
