Frequently Asked Questions
What is a dental implant?
This is a surgical procedure designed to replace a missing tooth. It is a titanium cylinder, which is surgically placed in bone to replace what was originally the root of the tooth. A crown is attached on to the implant to simulate the tooth.
The advancement in the implant treatment now mean:
- Minimally invasive surgery with no stitches
- Rapid recovery
- Immediate tooth replacement
- Long lasting treatment
How is a dental implant different from a bridge?
A dental implant literally replaces a missing tooth. A dental implant simulates the root of a tooth to which the cosmetic dentist attaches a cosmetic tooth. A dental bridge, on the other hand, is a non-surgical procedure that uses the adjacent teeth to support the missing tooth. A dental implant is not invasive to surrounding teeth (especially desirable if surrounding teeth are sound and healthy and in good condition).By simulating the root, it engages the bone and keeps it high. Because a dental implant is an individual tooth, it is easier to floss and keep clean. A dental bridge can also be a good choice for replacing missing teeth especially if neighbouring teeth are in need of restoration. However, there are subtle factors such as age, time, bone health, oral habits that should be discussed with Dr Ho when deciding which options may be best for you.
How long can a dental implant process take?
A standard implant on the lower jaw generally takes about 8 weeks to heal. On top jaws, they normally take 12 weeks. This does depend on density and bone health and quality. Some implants are ready for immediate restoration. If bone grafting or augmentation is required, this may lengthen the process up to a year.
Why is titanium used in the jawbone?
Titanium is an extremely biological friendly material, i.e. gum and bone bond well to this. Once placed in the jaw bone it becomes a permanent replacement for the missing tooth’s root structure.
What if there is not enough bone?
Successful implant placement does require a certain amount of bone in which to locate the fixture. In the absence of sufficient bone, augmentation or grafting procedures are usually possible. In very rare cases a lack of bone can make implant placement impossible.
Does the procedure hurt?
Local anesthesia ensures that the implant placement procedure is pain-free. Post-operative discomfort is usually minor and can be settled with oral painkillers.
How many dental visits are required?
The number of dental visits required, and the timeframe of treatment often depends on the circumstances of the case. Simple cases can be completed quickly in two visits, whereas more complex cases can require a number of appointments over several months.
How long do implant-retained crowns last?
With good home care and regular dental visits the lifespan of an implant-retained crown is usually at least 15 years. Eventually the overlying crown may need to be replaced because of wear; however, the implanted titanium screw can be used over and over again.
Candidates for implant-retained crowns
Implant-retained crowns are an ideal tooth replacement option for many patients. They offer a unique advantage over fixed bridges in that they are freestanding, so their placement does not affect adjacent teeth in any way.
Implant retained crowns are not a suitable tooth replacement option if:
- the patient is under 18 years of age
- the patient is medically compromised
- there is insufficient space or bone to enable placement
