An overdenture is a denture that is supported by sitting on either remaining natural tooth roots or dental implants instead of just being supported by the gums. This extra support helps the patients have a better ability to chew and speak because their denture is no longer loose.4
There are two main types:
There are three main subtypes that can be chosen by your dentist.4
Snap on Overdentures: the dental implants have small ball-shaped attachments connected to them, so the denture can snap locked into place.4
Bar-Retained Overdentures: Where the dental implants have a thin metal bar connected to them that is under the gum, your denture clips onto the bar.4
Fixed Implant Overdentures: The denture is permanently attached to dental implants using screws that are covered by a composite to hide completely.4
Step 1: Examination Evaluation
Dentist determines whether the patient is a good candidate. Additional procedures such as a bone graft or gum graft may be recommended if needed. X-rays or 3D scans are typically taken.5
Timeline: Initial diagnostic appointment
Step 2: Dental Implant Placement Day
While under local anesthesia, a hole is drilled into the jawbone and a medical grade titanium implant is screwed into the hole.5
Timeline: Procedure Time 1-2 hours per Implant Site
Step 3: Healing Period (Osseointegration)
The threads of the implant fuses with the jawbone to create a stable foundation (tooth root).5
Timeline: 3-6 months
Step 4: Scan andImpression
Digital scans or impressions are taken to create a custom-made crown that
matches the shape, size, and color of your natural teeth.5
Timeline: Scanning Appointment 1 Hour
1-2 weeks for lab to return
Step 5: Abutment
and Final Crown
Placement
After proper healing and fusion, a small connector piece (abutment) is placed
on top of the implant. A custom-made crown is attached once healing is
confirmed.5
Timeline: Final Appointment 1 Hour
1-2 weeks Healing Period
