Does Caffeine Affect Dental Implant Stability? A Prospective Cohort Study

Area of Science:

• Dental implantology
• Bone metabolism
• Caffeine's physiological effects

Background:

• Caffeine is known to affect bone metabolism by inhibiting osteoblast proliferation.
• The impact of caffeine consumption on dental implant osseointegration and stability remains unclear.

Purpose of the Study:

• To evaluate the influence of daily caffeine intake on dental implant stability.
• To assess implant stability during the healing period in patients with varying caffeine consumption levels.

Main Methods:

• A prospective cohort study involving 102 patients undergoing dental implant placement in the posterior maxilla.
• Patients were categorized into two groups: high caffeine consumers (≥400 mg/day) and low consumers (≤100 mg/day).
• Implant stability was measured using resonance frequency analysis (RFA) to determine implant stability quotients (ISQs) at 4, 6, and 8 weeks post-placement.

Main Results:

• No statistically significant differences in mean ISQ values were observed between the high and low caffeine consumption groups at 4, 6, or 8 weeks.
• Both groups demonstrated a similar pattern of increasing ISQ over the 8-week healing period.
• Statistical analysis (p=0.13, p=0.36, p=0.08 for weeks 4, 6, 8 respectively) confirmed no significant impact of caffeine on implant stability.

Conclusions:

• Current findings suggest that habitual caffeine intake, within the studied ranges, does not adversely affect dental implant stability in the posterior maxilla during the healing phase.
• Further research may explore dose-dependent effects or specific patient populations.
