Because Medisave can only be used for the surgical stage of an implant, up to $1,950 per implant. The crown, the abutment, scans, consultation and any part of the fee above that limit cannot come from Medisave, so the balance is paid in cash, by card or through insurance. A "zero cash" headline usually means the surgical stage alone has been priced at or under the limit; the crown is still paid separately. At Trust Dental Surgery an Osstem or Dentium implant with PFM crown is $2,449 in total: $1,950 from Medisave + $499 paid by you (before 9% GST).

Patients compare implant advertisements and see two very different messages: "from $499 after Medisave" on one, "$0 cash" on another. Both can be true at the same time, because they describe different parts of the same treatment. This page explains the arithmetic behind the cash top-up, what the zero-cash framing usually means, and how to compare quotes on the same basis.

The arithmetic of the cash top-up

CPF allows Medisave to be used for the surgical placement of an implant up to $1,950 per implant (the $1,120 operation limit plus up to $830 for day-surgery charges). That limit applies only to the surgical charges actually incurred. Everything else in a complete implant is outside it:

ItemMedisave?Paid how
Implant fixture surgeryYes, up to $1,950Medisave (own or family member's)
Abutment and crownNoCash, card or insurance
Consultation, X-rays, CBCT scanNoCash, card or insurance
Bone graft or sinus lift, if neededSometimes, under its own surgical limitMedisave for the claimable part; balance cash
Any fee above the $1,950 limitNoCash, card or insurance

Since the crown alone is typically a four-figure item in Singapore, a complete single implant with crown ends above $1,950 at almost every clinic, and the excess is the cash top-up. At Trust Dental Surgery that excess is $499 on a $2,449 package (Straumann: $1,499 on $3,449).

What "zero cash" or "$0 out-of-pocket" usually means

Every clinic in Singapore works under the same CPF limit, so the difference between a "$499 cash" clinic and a "$0 cash" clinic is presentation, not a different Medisave rule. A zero-cash headline normally means the clinic's fee for the surgical stage has been set at or below $1,950, so that stage can be settled entirely from Medisave. It does not mean Medisave is paying for the crown; Medisave cannot. The abutment and crown are then billed separately, usually at the restorative appointment some months later, or the complete package is priced above what Medisave can cover so that a cash balance appears at that point instead.

Neither approach is wrong. The useful comparison is the total cash across all visits for a finished tooth, not the cash on the day of surgery.

Five questions that put every quote on the same basis

  1. Does the quoted price include the abutment and the permanent crown, or only the fixture surgery?
  2. Is the CBCT scan included, and are bone grafts quoted separately?
  3. What is the total cash amount across all visits, assuming a full $1,950 Medisave claim?
  4. Is the price before or after 9% GST?
  5. What happens to the cash figure if my Medisave balance is below $1,950?

When the cash figure is higher than advertised

How it works at Trust Dental Surgery

Our single-implant packages include the fixture, abutment, PFM crown, CBCT scan and medication, so there is one price and one cash figure. You do not pay the Medisave portion upfront: on the day of surgery you sign the authorisation form, we submit the claim electronically, and only the balance is settled with us. For the full rules on limits, multiple implants and family accounts, see how Medisave claims for dental implants work.
