Same-Day Implants: Are You a Candidate?

A same-day implant — technically called an immediate-load or immediate-provisionalization implant — refers to a protocol where a temporary crown or full-arch prosthesis is attached to the implant post on the same day the post is placed in the bone. In traditional implant protocols, the implant is placed and then left to integrate with the bone for three to six months before any crown is attached. Same-day loading compresses that wait by providing a temporary tooth immediately, with the final permanent crown placed after full integration.

For All-on-4 full-arch restorations, same-day loading is actually the standard protocol — patients routinely leave with a full temporary arch of teeth on the day of surgery. For single-tooth or multiple-tooth implants, same-day loading is selective and depends on specific clinical factors that Dr. Kadivar evaluates during the consultation.

The critical factor in same-day loading candidacy is primary stability — the degree to which the implant post is mechanically locked into the bone at the moment of placement. Primary stability is measured by a device called an Osstell that generates an Implant Stability Quotient (ISQ) score. An ISQ of 70 or above is generally required for same-day loading. Below that threshold, early loading significantly increases the risk of micro-movement that prevents proper osseointegration.

Primary stability depends primarily on bone density and the precision of implant placement. Patients with dense, compact bone — common in the lower front jaw — often achieve excellent primary stability. Patients with softer, spongier bone — more typical in the upper back jaw — may not reach the required stability threshold and therefore require the traditional healing protocol before loading.

• High bone density (particularly lower jaw front area) — most favourable for immediate loading.
• Non-smoker — healing is faster and infection risk is lower, supporting early loading.
• No active infection at the implant site — infection before placement disqualifies immediate loading.
• Good systemic health — uncontrolled diabetes and immunocompromised states increase failure risk.
• Commitment to a soft diet for 6–8 weeks — the temporary crown must not bear full chewing force.

The procedure begins like any standard implant surgery: thorough local anaesthesia, precise osteotomy (drilling of the implant channel) using a surgical guide derived from 3D CT imaging, and placement of the titanium post. The implant stability is measured immediately after placement. If the ISQ score meets the threshold, the abutment and a pre-fabricated or chairside-milled temporary crown are attached. The entire surgical and restoration appointment typically takes two to three hours.

The temporary crown is designed so it does not bear the same forces as the final permanent crown — it is adjusted to be slightly out of contact with the opposing tooth when you close your bite. This protects the implant from lateral forces during osseointegration. After three to five months, the implant is checked with imaging, and if fully integrated, the final zirconia or porcelain crown is placed.

Patients with same-day temporary crowns must follow a strict soft diet for the first six to eight weeks. Hard foods, chewy meats, crusty bread and anything that requires significant biting force can apply micro-movements to the implant before osseointegration is complete — and micro-movement is the primary cause of immediate-load implant failure. Think of the temporary tooth like a screw that is partially tightened: it holds, but applying stress before it is fully locked in place can cause it to loosen.

The temporary crown should also not be used as a biting edge for tearing food or opening packaging. It is slightly shorter and out of contact with opposing teeth by design — this is intentional, not a mistake. Bruxism (teeth grinding) is a significant contraindication to same-day loading; patients with an active grinding habit require a night guard from day one and may be better served by the traditional loading protocol instead.

There are two distinct same-day protocols that patients sometimes confuse. The first is immediate implant placement: the implant post is placed on the same day a failing tooth is extracted, into the freshly extracted socket. This can be done in a single appointment but still follows a traditional or immediate-loading protocol depending on bone density. The second is immediate loading: a crown is attached on the same day the implant is placed, regardless of when the post went in.

For patients presenting with a failing or hopeless tooth, the ideal scenario is simultaneous extraction and immediate implant placement with immediate loading — a one-appointment solution from failing tooth to temporary crown. This is achievable for a significant proportion of patients in the lower front or premolar region when the socket is free of infection and bone volume is adequate.

A typical same-day implant timeline looks like this: Day 1 — surgery and temporary crown; Weeks 1–8 — soft diet and careful hygiene; Month 3–5 — integration confirmed by x-ray and stability measurement; Month 4–6 — final impression and permanent crown fabrication; Month 5–7 — final crown seated. Total time from surgery to final crown is roughly five to seven months, compared to six to nine months for traditional implant protocols — a modest but meaningful time saving.

For All-on-4 same-day full-arch restorations, the timeline is similar but the temporary full-arch prosthesis provided on day one is more functional than a single temporary crown, allowing patients to eat and speak normally (with dietary restrictions) from the very first day.

The only way to know if you qualify for a same-day implant is a consultation with 3D bone imaging. Bone density, anatomy, overall health, and the specific tooth position all play a role. During your consultation at Smile Dental Arts Centre, Dr. Kadivar will review your CT scan, measure available bone, assess your health history and give you a clear verdict on whether same-day loading is an option or whether the traditional staged protocol is more appropriate for your case.
