Optimizing implant stability: what is the relationship between surgical techniques and implant macro-design?
This summary of research is adapted from the article published in the journal of Clinical Implant Dentistry: Evaluation of Primary Stability of Self-Tapping and Non-Self-Tapping Dental Implants. A 12-Week Clinical Study. Purpose The study aimed at investigating the relationship between surgical techniques and implant macro-design (self-tapping/non-self-tapping) for the optimization of implant stability in the low-density bone present in the posterior maxilla, using resonance frequency analysis (RFA). Materials and Methods A total of 102 implants were studied. Fifty-six self-tapping BlueSkyBredent® and 56 non-self-tapping Standard Plus Straumann® were placed in the posterior segment of the maxilla. Implants of both types were placed in ...Read More »
