A single dental implant works well for one missing tooth, but patients missing most or all of their teeth need a different approach: an implant-supported denture. Anchored to dental implants placed in the jawbone rather than resting loosely on the gum ridge, these appliances give patients a level of stability and chewing function that traditional dentures simply cannot match. Dr. Raymond J. Haigney II, FACS at Lake Norman Oral & Facial Surgery works with restorative dentists throughout Huntersville and the Charlotte metro to plan and place the implants behind these full-arch solutions.
There are four main categories of denture implants, split between fixed appliances that stay in the mouth permanently and removable options that patients take out for cleaning. The right fit depends on how much bone is available, your budget, and how much flexibility you want in day-to-day care.
Fixed denture implants are permanently affixed and never removed by the patient for cleaning or repair. There are two main versions:
This is the more durable and typically more attractive of the two fixed options. Relying on four to eight implant fixtures, a fixed implant-supported bridge includes a full or partial bridge fabricated from porcelain, zirconium, or a hybrid composite for a strong, natural-looking result. Because it uses more implant fixtures for support, this design can continue functioning even if a single implant develops an issue over time, though the higher fixture count also means a higher upfront cost than the alternative below.
Often called “all-on-4” dentures, this design typically uses four implant fixtures, though some cases call for more. Like the fixed bridge above, it is non-removable. Because it relies on fewer implants, it generally supports slightly fewer teeth — the farthest back one or two positions are often not reproduced — and the prosthetic teeth are usually acrylic rather than porcelain or zirconium, making them somewhat more prone to wear over time. The lower fixture count and lower-cost materials make this option more accessible for many patients, but it also means that if one implant loses integration, the whole appliance can be affected.
Some patients prefer the flexibility of a removable design that can be taken out for thorough cleaning or repair. Two options fall into this category:
These function much like the fixed implant-supported denture described above but can be removed by the patient. Many designs include a metal bar connecting four implant fixtures, along with a slightly extended prosthetic gumline for patients whose natural smile shows more gum tissue. Cost is comparable to, or sometimes higher than, a fixed implant-supported denture, but repairs tend to be simpler and less expensive.
This design is more of a hybrid between a traditional denture and a full implant-supported appliance. Rather than four to eight fixtures, as few as two implants can support the denture, though some dentists recommend more for added stability. It is generally the most cost-effective implant-denture option, but with fewer anchor points it can feel slightly less stable than the alternatives above and may cause more discomfort for some patients over time.
The number of implants required depends on the design you choose and the bone available to support them. A full fixed bridge often uses six to eight implants per arch for maximum long-term redundancy, while an all-on-4 appliance is engineered specifically to distribute chewing forces across just four strategically angled fixtures. Overdentures can use anywhere from two to six implants depending on the level of stability desired. A 3D scan lets Dr. Haigney determine the exact number and placement pattern that will give your specific jaw the strongest, most predictable support.
Bone volume, budget, and how much flexibility you want in daily care all factor into which denture-implant design fits best. A 3D scan lets your care team see exactly how much bone is available and whether a bone graft would be needed before implants can be placed. From there, Dr. Haigney can walk through which of the four options — fixed bridge, all-on-4, overdenture, or implant-retained overdenture — matches your goals and anatomy.

Words cannot express enough, how wonderful, caring and professional Dr. Haigney and his staff are! After being rushed to the Huntersville hospital with an orbital fracture, broken nose and other facial damage, Dr. Haigney rushed me into surgery (on his day off I must add) and corrected all my problems. I only wish all doctors cared as much about their patients and their recovery as Dr. Haigney and his staff did. Thank you so much for everything! Your attention and compassion has helped me make my recovery as comfortable as possible. 5 star service!
