Dental Implants Immediate Loading Versus the Standard 2-Staged Protocol: An Experimental Study in Dogs
The endeavors to shorten implant treatment time have led to the concept of immediate loading. This research was designed to compare the immediate loading and the 2-staged methods on implant placement from a clinical, histological, and histomorphometric standpoint. Three months postextraction of 12 premolars of 3 dogs, 12 implants were inserted. Bone-implant contact (BIC), implant stability quotient (ISQ), the bone type in a 2-mm periphery around the implant, and the marginal bone loss (MBL) were recorded for unloaded implants (n = 6) and immediately loaded ones (n = 6). BIC, ISQ, MBL in the mesial, and the bone types around the implants were not significantly different in the 2 groups. The distal MBL was higher in the immediately loaded group. Immediate loading does not appear to be perilous for osseointegration, BIC, or new bone type around implants.
