Does Biphasic Calcium Phosphate-Coated Surface Increase the Secondary Stability in Dental Implants? A Split-Mouth...

Area of Science:

• Biomaterials Science
• Dental Implantology
• Orthopedic Research

Background:

• Secondary stability is crucial for successful dental implant osseointegration.
• Surface modifications aim to enhance implant osseointegration and stability.
• Comparing different surface coatings is essential for optimizing dental implant outcomes.

Purpose of the Study:

• To evaluate the secondary stability of biphasic calcium phosphate coating (BCPC) dental implants.
• To compare BCPC implants with sand-blasted and acid-etched (SLA) implants regarding secondary stability.

Main Methods:

• A split-mouth study design was employed with 30 subjects receiving bilateral mandibular molar implants.
• Implants were randomly assigned to either BCPC or SLA groups.
• Resonance frequency analysis (RFA) was used to measure implant stability (ISQ) at 2, 4, 6, and 8 weeks post-placement.

Main Results:

• Sixty implants were analyzed (30 per group).
• BCPC implants demonstrated progressively higher mean implant stability quotient (ISQ) values compared to SLA implants throughout the 8-week evaluation period.
• Statistical analysis revealed significant differences in mean ISQ between the BCPC and SLA groups at all measurement time points.

Conclusions:

• BCPC coating may enhance the secondary stability of dental implants compared to SLA surfaces.
• Higher implant stability observed with BCPC suggests improved osseointegration potential.
• Further research is warranted to confirm long-term clinical outcomes.
