“…In another experiment in 6 Labrador dogs including a shorter period of function compared to the previously discussed studies, all mandibular premolars and the first molars were extracted, while the second molars were maintained bilaterally, preserving the distal support in centric occlusion. Two implants were installed 3 months after tooth extraction on both sides of the mandible in the premolar region using insertion torques of about either 30 or >70 Ncm.…”

“…Several experiments evaluating the effect of loading on osseointegration also have been performed in various animal models, such as monkeys, dogs, pigs and rabbits . Some experiments evaluated osseointegration when a physiologic load was applied . Other experiments applied an overload at the test sites, or a non‐axial load or a lateral load …”

To evaluate presumptive differences in osseointegration at implants supporting crowns that are physiologically loaded either immediately or 3 months after installation. All premolars and first molars were extracted bilaterally in six dogs. After 3 months of healing, three implants were installed on the premolar region and two in the molar region in one side of the mandible. Likewise, after another 3 months, five implants were installed in the contralateral side, and impressions were taken bilaterally. Within 48 hours, two single crowns were screwed bilaterally onto two implants in the premolar region, and two splinted crowns reproducing the shape of the first molar were screwed bilaterally onto the implants in the molar region. The mesial implants were used as no-loaded controls. Sacrifices were performed after 3 months, and histological analyses were performed. At the premolar sites, mineralised bone-to-implant contact (MBIC%) was 78.0 ± 4.0% and 70.9 ± 7.9% at the delayed and immediately loaded sites, respectively. This difference was statistically significant. At the control implants, MBIC% was 61.4 ± 14.7% and 63.1 ± 13.1% at the delayed and the immediately loaded sites, respectively. At the molar sites, MBIC% was 79.2 ± 10.9% and 61.1 ± 10.3% at the delayed and immediately loaded sites, respectively. Applying a delayed loading to fixed dental prostheses supported by single or two splinted implants yielded higher proportions of bone-to-implant contact (osseointegration) compared to immediately loaded implants. Moreover, both types of loading protocols yielded a higher rate of osseointegration compared to unloaded implant sites after 3 months following implant installation.

“…[5][6][7][8][9][10] Other authors reported that high insertion torque value is one of the main causes of marginal bone resorption 11 or, however, not necessary. [12][13][14][15] The aim of this article is to review the recent international literature about low and high implant insertion torque investigating their effects on marginal bone loss and implant survival rate.…”
