Implants for Diabetics: The HbA1c Threshold

The threshold

• Under 7%: excellent candidate
• 7–8%: good candidate with monitoring
• 8–10%: optimise diabetes first
• Over 10%: implants deferred

Why it matters

Poorly controlled diabetes slows healing and increases infection risk 2–3×. Well-controlled diabetes has implant outcomes equivalent to non-diabetics.

Pre-op

• Recent HbA1c
• Physician clearance if above 8%
• Review diabetes medications
• Consider antibiotic prophylaxis

Post-op

• Stricter hygiene
• More frequent follow-ups
• Hygiene every 3 months

Long-term

Absolute success rates within 2 percentage points of non-diabetics when well controlled.

Practical decision guide

Implant planning is a medical and engineering decision. The useful question is not only whether an implant can be placed, but whether the bone, gum, bite, medical history, hygiene routine, and restoration design make it likely to stay healthy.

Check this first

• CBCT bone volume, gum thickness, sinus or nerve position, smoking/vaping history, diabetes control, and periodontal status.
• Whether the missing-tooth space needs grafting, sinus lift, temporary teeth, or staged treatment.
• How the final crown, bridge, denture, or full-arch restoration will be cleaned and maintained.

When to book sooner

• There is swelling, pus, implant mobility, persistent bleeding, or a bad taste around an implant.
• A recent extraction site is planned for an implant but no grafting or bone-preservation discussion happened.
• You have uncontrolled diabetes, active gum disease, heavy smoking, or bisphosphonate/osteoporosis medication history.

Topic-specific notes

• For implant treatment, ask how bone, gum thickness, bite forces, smoking, diabetes control, and cleaning access affect the plan. A technically placed implant still fails if the long-term maintenance plan is weak.
• For medical conditions, bring a medication list and relevant physician details. Dental risk often changes through saliva, healing, bleeding, immunity, reflux, or blood-sugar control.

Questions to ask at the appointment

• Do I need a CBCT scan, graft, sinus lift, or soft-tissue graft before implant placement?
• Which implant system is being used, and can replacement parts be sourced long term?
• How often should this implant be professionally cleaned, and what tools should I use at home?

Dubai patient note

Dubai implant quotes vary because they may or may not include CBCT, surgical guide, grafting, abutment, crown, temporary tooth, sedation, and follow-up. Compare itemised plans rather than headline implant prices.
