Immediate-Load Implants Explained

What immediate load means

Traditional implant protocol waits 3–4 months between placing the implant and loading it with a crown or bridge. Immediate load places a temporary tooth (or bridge) on the implant at the same surgery, or within 24–48 hours.

What's actually possible same day

Single tooth immediate temporary

Common and reliable for well-planned cases. A temporary crown is placed out of direct bite contact so it doesn't disturb osseointegration during healing. Final crown comes at 3–4 months.

All-on-4 immediate bridge

Highly successful with good case selection. A full-arch temporary bridge is screwed onto 4 implants on the surgery day. You leave with working teeth.

Immediate loading in the aesthetic zone

Single front-tooth implants often benefit from immediate temporisation — preserves gum contour and avoids a visible gap.

What requires waiting

• Cases with poor bone quality (soft, Type 4 bone)
• Cases where primary stability is low at surgery
• Heavy smokers
• Uncontrolled diabetics
• Immunocompromised patients
• Very large bone grafts placed simultaneously

The 35 Ncm rule

We measure insertion torque when placing the implant. Above 35 Newton-centimetres of primary stability, immediate loading is generally safe. Below 35, we wait for osseointegration. This is a quick, objective measurement done at surgery.

Failure rates

• Delayed loading: 95–97% success at 5 years
• Immediate loading (well-selected cases): 94–96% at 5 years
• Immediate loading in poor bone / heavy smokers: 80–85%

Case selection matters more than the protocol.

What you can and can't eat

Immediate-load temporaries are for appearance and speech, not heavy chewing. For the first 8–12 weeks:

• Soft foods on the implant side
• Chew hard foods on the opposite side
• No biting into apples, steak, crusty bread on the implant side
• No using the front teeth as tools (tearing tape, opening packages)

Advantages of immediate load

• One surgery instead of two
• No visible gap, no denture needed during healing
• Faster overall treatment
• Better gum contour around front teeth

Disadvantages

• Slightly higher failure rate in some studies
• Higher cost (laboratory work for temporary + final)
• Strict diet restrictions during healing
• Requires skilled team and good primary stability

Who should not get immediate load

• Severe grinders without a nightguard protocol
• Patients who can't follow diet restrictions
• Uncontrolled systemic disease
• Very poor bone requiring simultaneous major grafting
