Abstract:
OBJECTIVETo study the effects of progressive loading on implants placed into extraction sockets.
METHODSBilateral 3rd, 4th and 2nd premolar of 4 beagle dogs were extracted and the implants were immediately inserted at 0, 14 and 21 days. The progressive loading procedure was conducted after 24 hours. The vertical bone loss (VBL) and the bone/biomaterials reactions were detected by X-ray and SEM.
RESULTSThe VBL in control groups was larger than that for the experimental groups at 14, 21 and 28 days (P<0.05). Scan electron microscopy detected that the mineralization speed of experimental groups was many times as faster as the control groups.
CONCLUSIONProgressive loading of implants placed into extraction sockets can be performed without disturbing the osseointegration process. The potential of new bone formation in the extraction sockets and the physical strains can congenerously promote osseointegration.
