Sequential Healing at Implants with Different Configuration and Modified Surfaces: An Experimental Study in the Dog.

Area of Science:

• Dental Implantology
• Biomaterials Science
• Histology

Background:

• Dental implant surface modifications are crucial for osseointegration.
• Comparing different implant systems and their surface properties is essential for clinical success.

Purpose of the Study:

• To evaluate peri-implant soft and hard tissue adaptation.
• To compare two trans-mucosal implant systems with different modified surfaces.
• To assess osseointegration at different healing times.

Main Methods:

• Six Beagle dogs underwent surgical procedures for implant placement.
• Two implant systems (ICX-Gold and SLActive) with distinct surfaces were randomly installed.
• Histological examination of biopsies was performed after 1 and 2 months of healing.

Main Results:

• Both implant systems demonstrated similar marginal bone and soft tissue dimensions.
• New bone formation percentages were comparable between ICX-Gold (69.0% at 1 month, 67.8% at 2 months) and SLActive (68.8% at 1 month, 71.9% at 2 months) surfaces.
• No statistically significant differences in osseointegration were observed between the two implant systems.

Conclusions:

• The ICX-Gold and SLActive implant systems exhibit comparable osseointegration.
• Both implant systems provide similar soft and hard tissue adaptation.
• Clinical outcomes are likely similar for these two implant systems regarding osseointegration.
