Screw-Type Collar vs. Non-Screw-Type Collar Implants-Comparison of Initial Stability, Soft Tissue Adaptation, and Early Marginal Bone Loss-A Preclinical Study in the Dog.

When a two-stage implant protocol was used, rough-surface non-screw-type collar implants led to superior outcomes at 2nd-stage surgery. Implant location did not affect the results. The significance of this result in preventing EMBL awaits further research.
