Implant-Supported Overdentures
Solutions.

Overdentures are removable - you take them out for cleaning at night. All-on-4 is fixed - the teeth are screwed onto implants and only a dentist can remove them. Overdentures typically use 2-4 implants per arch and cost $8,000-$15,000. All-on-4 uses 4 implants per arch and costs $20,000-$25,000. Overdentures are more affordable and easier to clean. All-on-4 provides a fixed solution and superior stability. Both preserve jawbone and eliminate slipping.

Lower overdentures typically need 2-4 implants. 2 implants provide good stability for most patients. 4 implants provide maximum stability for heavy chewers. Upper overdentures typically need 4-6 implants due to softer bone and larger arch. We assess your specific needs during consultation based on your bone density, bite force, and budget.

Yes, in many cases! If your existing dentures are in good condition and fit well, we can convert them to overdentures by placing implants and adding snap attachments to your denture. This saves the cost of a new denture ($2,500-$4,000). Total cost for conversion: $6,000-$10,000 (implants + attachments only). We assess your dentures during consultation to determine if conversion is possible.

Overdentures cost $8,000-$15,000 per arch in Melbourne (Oak Park pricing). Lower arch with 2-4 implants: $8,000-$12,000. Upper arch with 4-6 implants: $12,000-$18,000. This includes implants, surgical placement, and overdenture with attachments. Converting existing dentures: $6,000-$10,000 (implants + attachments only). Payment plans available (12-60 months). Health insurance provides $1,000-$2,000 rebate typically. See our [cost guide](/blog/dental-implant-cost-breakdown-melbourne-2026/).

Yes, for most patients. Overdentures provide superior stability (no slipping), better chewing function (60-70% vs 25-30% of natural), preserve jawbone (implants stimulate bone), and eliminate need for adhesives. However, overdentures cost more upfront ($8,000-$15,000 vs $2,500-$4,000). Long-term, overdentures provide better quality of life and may be more cost-effective due to reduced maintenance. See our [comparison guide](/blog/implant-dentures-vs-traditional-cost-comparison-melbourne/).

No, properly fitted overdentures snap securely onto implants and don't slip or move when eating or speaking. The snap attachments hold the denture firmly in place. You can eat, speak, and laugh with confidence. No adhesives needed. However, you can still remove the overdenture for cleaning (unlike All-on-4 which is fixed).

The implants can last 20+ years or a lifetime with proper care (95-98% success rate at 10 years). The overdenture itself typically lasts 10-15 years before needing replacement. The snap attachments wear out every 1-2 years and need replacement ($200-$400, simple procedure). With proper care and regular checkups, overdentures are a long-term solution.

We recommend removing overdentures at night to give your gums a rest and allow you to clean them thoroughly. However, some patients prefer to sleep with their overdentures in, which is usually fine if they fit well and you clean them daily. Discuss your preference with us during consultation.

Remove your overdenture and clean it daily with a soft toothbrush and mild soap or denture cleaner. Soak overnight in denture cleaning solution or water. Clean around the implants with a soft toothbrush and floss. Use a water flosser for thorough cleaning around implants. Attend professional cleanings every 6-12 months. Proper hygiene prevents peri-implantitis (gum disease around implants).

If one implant fails, the remaining implants usually provide sufficient support for the overdenture to function. The failed implant can be removed and replaced. Implant failure occurs in 2-5% of cases, usually due to smoking, poor oral hygiene, or insufficient osseointegration. See our [implant failure guide](/blog/dental-implant-failure-problems-warning-signs/) for warning signs and prevention.
