Bone and soft tissue integration to titanium implants with different surface topography: an experimental study in the...

Area of Science:

• Dental Implantology
• Biomaterials Science
• Periodontology

Background:

• Titanium implants are widely used in dental restorations.
• Surface modifications aim to enhance osseointegration and long-term stability.
• Comparing different implant surface topographies is crucial for clinical success.

Purpose of the Study:

• To evaluate peri-implant soft and hard tissues around two distinct titanium implant surfaces.
• To provide a topographic description of the implant surfaces.
• To compare bone-to-implant contact (BIC%) and bone density between standard implants (SI) and Osseotite implants (OI).

Main Methods:

• Five beagle dogs underwent mandibular premolar extraction.
• Standard implants (SI) and Osseotite implants (OI) were placed three months post-extraction.
• Biopsies were obtained after six months for histometric analysis using EPON embedding and ground sectioning.
• Bone-to-implant contact (BIC%) and bone density were assessed in defined zones.

Main Results:

• Peri-implant soft tissues and marginal bone-to-implant contact were comparable between SI and OI.
• Osseotite implants (OI) exhibited significantly higher BIC% (76.7% in zone II, 72.0% overall) compared to standard implants (SI) (56.1% in zone II, 58.1% overall).
• Bone density measurements were similar for both implant types across all assessed zones.

Conclusions:

• Osseotite implant surfaces promote superior bone-to-implant contact compared to standard implant surfaces.
• Both implant types provide similar soft tissue integration and bone density.
• Surface topography plays a significant role in achieving enhanced osseointegration.
