Pre-Prosthetic Surgery
in Honolulu, HI
 Pre-prosthetic surgery in Honolulu, HI is the surgical preparation of your gums and jawbone so a denture or full-arch prosthetic fits comfortably and stays stable.
At Pacific Maxillofacial Center, our board-certified oral and maxillofacial surgeons reshape the ridge, remove bony growths, and smooth the foundation your new teeth will rest on, so the final prosthetic fits the way it should.
If your dentist has told you that you need work done before your dentures can be made, this is usually what they mean. A denture or full-arch restoration is only as comfortable as the ridge underneath it, and a few common surgical adjustments can be the difference between a denture that fits well and one that rocks, rubs, or never feels right. Pre-prosthetic surgery is part of our broader oral surgery care, and it is most often done after teeth are removed but before the final prosthetic is fitted.

What Is Pre-Prosthetic Surgery?
 Pre-prosthetic surgery is a group of procedures that reshape the bone and soft tissue so a denture or full-arch prosthetic has a smooth, stable foundation to sit on. After teeth are removed, the ridge is often uneven, and sharp edges, bony bumps, or muscle attachments can keep a denture from seating properly. We correct those issues before the prosthetic is made. Which procedures you need depends entirely on your own anatomy, and most patients need only one or two of the following:
- Alveoloplasty – Smoothing and recontouring the ridge after extractions so it presents an even surface for the denture to rest on.
- Tori removal – Removing tori, the benign bony growths that form on the roof of the mouth or the inside of the lower jaw, when they sit where the denture needs to seat.
- Tuberosity reduction – Trimming excess bone behind the upper back teeth so the denture has room to fit without rocking.
- Frenectomy – Releasing a frenum, the small band of tissue connecting the lip or cheek to the gum, when its attachment pulls on the denture border and unseats it.
- Ridge augmentation – Adding bone where the ridge is too thin or too short to support the prosthetic, using a bone graft to rebuild it.
Because pre-prosthetic surgery so often follows tooth removal, we frequently combine it with multiple extractions in the same visit, which spares you a separate surgery and recovery.
Your Pre-Prosthetic Surgeons in Honolulu
Dr. Todd K. Haruki and Dr. Neil Oishi both hold DDS and MD degrees and are Diplomates of the American Board of Oral and Maxillofacial Surgery. Reshaping bone so a prosthetic seats evenly is precise work, and it draws on the same surgical training that managing facial bone requires.
Dr. Oishi serves as an on-call facial trauma surgeon at Queen's Medical Center, where reconstructing and reshaping facial bone is routine. That reconstructive experience carries directly into pre-prosthetic work, where the goal is a smooth, well-contoured ridge.
Dr. Haruki founded Pacific Maxillofacial Center in 1999 and is a Fellow of the American Dental Society of Anesthesiology. Pre-prosthetic procedures are often combined with extractions in one sitting, so the in-office sedation his anesthesia training supports lets us complete more in a single comfortable appointment. We offer the full range of sedation options without referring out.
The Pre-Prosthetic Surgery Process
Pre-prosthetic surgery is planned around your final prosthetic, so the steps line up with your denture or full-arch timeline. The process at our Honolulu and Waipi'o offices runs like this:
| 1. |
Consultation and imaging – We examine your ridge and take a cone beam CT scan to see the bone in three dimensions, which shows exactly where reshaping or augmentation is needed. More on our surgical imaging technology.
|
| 2. |
Treatment plan and sedation discussion – We map out which procedures your case needs, whether they pair with extractions, and what sedation keeps you comfortable. Many patients choose IV sedation for combined procedures.
|
| 3. |
The surgery – We reshape or remove the bone and tissue identified in the plan, often in the same visit as any needed extractions. Combining the work means one recovery instead of several.
|
| 4. |
Healing period – The ridge needs time to heal and stabilize before the final prosthetic is fitted, usually several weeks to a few months depending on how much was done. Our post-op instructions for multiple extractions cover much of what to expect during recovery.
|
| 5. |
Coordination with your restorative dentist – Once the ridge has healed, your restorative dentist takes impressions and builds the denture or prosthetic onto the prepared foundation. We time the surgery so your final teeth are ready when your mouth is. |
Why a Prepared Ridge Matters
 A denture rests on the ridge the way a building rests on its foundation. If the foundation is uneven, no amount of adjusting the denture itself fully fixes the fit, which is why we prepare the ridge first rather than asking your dentist to compensate later.
We smooth the ridge so the denture seats evenly and spreads bite force across the whole arch, which means less rocking and far fewer sore spots. We remove a torus or reduce a tuberosity so the denture border has somewhere to sit instead of riding over a bony bump. We release a frenum that tugs on the denture edge so everyday talking and smiling don't break the seal. And where the ridge is too thin, we augment it with enough bone to hold the prosthetic. We decide which of these you need from the CBCT scan, not by guesswork, so the surgery addresses your actual anatomy.
We coordinate the timeline with your restorative dentist so the prepared ridge and the finished denture line up. For patients heading toward a fixed solution rather than a removable one, the same groundwork supports an All-on-4 restoration or a full mouth restoration.
Why Choose Our Team for Pre-Prosthetic Surgery
Pre-prosthetic surgery is easy to underestimate. It is not the glamorous part of getting new teeth, but it is the part that determines whether those teeth are comfortable for years or a constant frustration, which is why dentists across Honolulu and West Oahu refer this groundwork to an oral surgery practice rather than handle it in-house. We treat it as seriously as the prosthetic it supports.
A few specifics from our practice. Both surgeons are dual-degree DDS/MD oral and maxillofacial surgeons, trained in exactly the bone and soft-tissue work these procedures require. We CBCT-scan the ridge before surgery so we reshape only what needs reshaping and preserve the bone that supports the denture. We combine pre-prosthetic work with extractions in one sitting where it makes sense, sparing you separate surgeries and recoveries. And we offer the full range of sedation in-office, including IV sedation administered by Dr. Haruki's anesthesia-trained team.
We also coordinate directly with the restorative dentist building your denture, so the surgery and the prosthetic are planned as one treatment rather than two disconnected steps.
Pre-Prosthetic Surgery Cost and Financing
Cost matters, and we want to be straight with you. Pre-prosthetic surgery is not a separate add-on so much as the foundation of your denture plan, and its cost depends on which procedures your case actually needs. Smoothing a single ridge is a smaller undertaking than removing tori, reducing a tuberosity, and augmenting bone all at once. We give you a written estimate at the consultation, once the CBCT scan shows what your mouth requires.
Insurance coverage varies. Some plans cover the surgical preparation as part of denture treatment, while others handle it separately, and coverage often depends on whether extractions are involved. Our team verifies your benefits before treatment and explains what your plan covers. Our financial and insurance options cover accepted payment methods, and we can set up payment plans for the balance. Call our office to go over coverage for your specific case.

Frequently Asked Questions
Why do I need surgery before getting dentures?
Not everyone does. But a denture only fits well if the ridge beneath it is smooth and even, and extractions often leave behind bumps, sharp edges, or uneven bone that a denture would rock or rub against. Pre-prosthetic surgery corrects those problem spots first, so the finished denture seats evenly. Skipping it when it is needed usually means a denture that never quite settles, or one that has to be remade.
Will I need all of these procedures?
Almost certainly not. Most patients need only one or two, and some need none if their ridge healed evenly after extractions. We decide exactly what your case requires from a CBCT scan that shows the bone in three dimensions, so we reshape only what actually needs it and leave the rest alone.
Can pre-prosthetic surgery be done at the same time as my extractions?
Often, yes, and we prefer to when it makes sense. Combining ridge work with multiple extractions means one surgery and one recovery instead of two. We make that call based on how much work is needed and your overall health, and we go over the plan with you before anything is scheduled.
Does pre-prosthetic surgery hurt?
During the procedure, no. We fully numb the area, and most patients choose IV sedation, especially when the surgery is combined with extractions. Afterward, the discomfort is similar to having teeth removed, manageable with over-the-counter or prescribed pain medication and ice for the first few days.
How long until I get my dentures after the surgery?
Minor smoothing may need only a few weeks of healing, while bone augmentation can take a few months before the ridge is ready for the final prosthetic. In some cases your restorative dentist fits a temporary or immediate denture during healing. We time the surgery so your final denture is ready when your ridge is.
What is a torus, and does it always need to be removed?
A torus is a benign, harmless growth of extra bone, usually on the roof of the mouth or the inside of the lower jaw. Many people have one and never need it touched. We only remove a torus when it falls in the path of the denture and would stop it from seating properly. If it sits clear of the denture, we leave it alone.
Can I wear a denture while my ridge heals?
Often yes, with adjustments. If you have an existing denture, it usually needs to be relined or modified to fit the changed ridge during healing, which your restorative dentist handles. Some patients receive an immediate or temporary denture instead. We coordinate the timing with your dentist so you are not left without teeth while the ridge settles.
Do I still need this if I'm getting implants instead of dentures?
Sometimes. Implant-supported options like All-on-4 still need a stable, healthy foundation, and you may need ridge smoothing or a bone graft to support the implants. The difference is that the planning centers on where the implants go rather than how a removable denture seats. We evaluate this from the same CBCT scan. |
