Novel Implant Design Improves Implant Survival in Multirooted Extraction Sites: A Preclinical Pilot Study

Background: The primary aim is to evaluate clinical, radiographic, and histologic parameters of novel implants with “three roots” design that were inserted into fresh multirooted extraction sockets. A secondary aim is to compare this new implant to standard root‐form dental implants. Methods: Immediate implantation of novel or standard design 6 × 6‐mm implants was performed bilaterally into multirooted sockets in mandibles of mini‐pigs. Twelve weeks later, clinical, radiographic, stability, histomorphometric, and microcomputed tomography (micro‐CT) analyses were performed. Results: Survival rates were significantly higher in the test implants compared with control (92.8% versus 33.3%, respectively; P
