Pre-prosthetic surgeries are surgical adjustments performed on the jawbones and soft tissues to ensure that removable (complete or partial dentures) or fixed prostheses (implant-supported restorations, bridges) fit perfectly, remain stable, and appear aesthetic in the mouth. These procedures, which resolve problems such as sores, pain, chewing difficulties, and the displacement of the prosthesis while speaking by addressing the root cause before the prosthesis is even made, are the most fundamental preparatory stage of a successful prosthetic treatment. At Dentmetrik, we perform all necessary pre-prosthetic surgical interventions painlessly using modern technologies and expert maxillofacial surgeons so that our patients can use their new teeth with high comfort, just like their natural teeth.

Definition and Purpose of Pre-Prosthetic Surgeries

Pre-prosthetic surgery is the general name given to all surgical interventions where the hard tissues (alveolar jawbone) and soft tissues (attachment sites for gums, cheeks, lips, and tongue muscles) in the patient's oral cavity are resized and reshaped (modified) to best support the upcoming prosthesis. When many years pass after tooth loss, irregular resorption occurs in the jawbones, and sharp protrusions form on the bone surface that can cause the prosthesis to dig into the tissue. Similarly, folds in the gums or loose, sagging soft tissues may develop, hindering the stability of the prosthesis.

The primary medical goal of this specific surgical group is to transform the patient's oral anatomy into the most ideal 'foundation' or 'base' for the type of prosthesis to be applied. Just as a building requires a solid foundation, dental prostheses need a smooth and sufficiently wide bone/tissue surface that can distribute chewing forces evenly. Thanks to pre-prosthetic procedures, the vacuum effect (retention) of dentures is maximized, food entrapment under the prosthesis is prevented, aesthetic lip and cheek support is provided, and most importantly, chronic pain that the patient would otherwise experience due to prosthetic sores is completely prevented before the operation.

Types and Applications of Pre-Prosthetic Surgery

Pre-prosthetic surgical procedures cover a wide range based on the anatomical obstacles in the patient's oral structure and the type of planned prosthesis (fixed, removable, or implant-supported). The primary types of pre-prosthetic surgery applied at Dentmetrik clinics, following detailed examinations and joint decisions by prosthetic and maxillofacial surgery specialists, are:

  1. Alveoloplasty (Bone Contouring): The process of shaving, rounding, and smoothing sharp and irregular bone edges remaining on the surface of the jawbone after multiple tooth extractions or years of resorption. It prevents the prosthesis from digging into the underlying tissue and causing ulcers.
  2. Removal of Torus and Exostosis: Structural bone protrusions (tori) may be present in the center of the upper palate or on the tongue side of the lower jaw; these are completely benign but bulky. Since these hard protrusions pose a physical barrier to the seating of removable dentures, they are surgically flattened.
  3. Frenectomy (Lip and Tongue Tie Release): In some patients, the muscle tissues (frenulum) connecting the lips, cheeks, and tongue to the jawbone attach very close to the dental crest (the ridge where the prosthesis sits). As the lips or tongue move, these muscles can dislodge the prosthesis. The length of these ties is shortened or their position is changed using laser or traditional surgical methods.
  4. Flabby Ridge (Mobile Tissue) Excision: This occurs when the jawbone has resorbed excessively, but the overlying gum becomes redundant, creating a spongy, mobile (flabby) structure. Since this mobile tissue provides no solid support for the prosthesis, it is surgically excised to reach the underlying firm bone tissue.
  5. Vestibuloplasty (Sulcus Deepening): Applied in cases where the groove (vestibule) between the lips/cheeks and the jawbone is anatomically too shallow. These grooves are surgically deepened to create sufficient surface area for the edges of the removable prosthesis to grip and create a vacuum.
  6. Ridge Augmentation (Bone Grafting): Bone powder (graft) placement operations performed to create a load-bearing area for prostheses or implants in cases where the jawbone is too thin or insufficient in vertical or horizontal directions.

The Procedure and Process

The pre-prosthetic preparation process is a highly planned path where different disciplines of dentistry converge. First, our prosthetic specialists take a preliminary impression from the patient, and a 'treatment prosthesis' (virtual planning) tailored to the patient's oral structure is created. Then, our maxillofacial surgeons examine the thickness of the bone and soft tissues with millimetric precision using 3D Dental Tomography (CBCT) and panoramic X-rays. All anatomical obstacles (bone spikes, tori, high muscle attachments) that would prevent the prosthesis from seating are identified, and a personalized surgical map is developed.

The operation process begins with the patient receiving general anesthesia, conscious sedation, or simply local anesthesia; typically, these procedures are comfortably completed in a clinical setting under local anesthesia. The gum is precisely opened to reach the problematic underlying bone tissue. Sharp bones are smoothed using specialized surgical burs (bone files), and excess muscle tissues are often adjusted using dental lasers, a technology that is frequently bloodless and suture-free. Once the tissues reach their ideal form, the incision sites are closed with aesthetic, fine sutures. Most pre-prosthetic procedures are completed in a single session, taking approximately 30–45 minutes.

The recovery process depends on the extent of the surgery performed. While procedures involving only soft tissue (gum/muscle), such as a frenectomy, heal within a few days, it may be necessary to wait 3 to 6 weeks for tissues to become stable enough for final prosthetic impressions in cases of bone shaving (alveoloplasty). During this waiting period, a soft liner is placed inside the patient's existing old dentures to ensure they do not remain toothless and to allow the tissues to adapt to their new shape, enabling the patient to continue their daily life comfortably. Once healing is complete, the manufacturing phase of the brand-new, perfectly fitting permanent prostheses begins.

What Are the Advantages of Pre-Prosthetic Surgeries?

The greatest and indisputable advantage of pre-prosthetic surgeries is the creation of 'stability' and 'comfort' in prosthetic use. All psychological and physical problems, such as prostheses causing sores, pain during eating, or embarrassing social moments due to sudden displacement while speaking, are permanently eliminated through these surgical interventions. Because the bone base is completely smoothed, the prosthesis grips the oral tissues firmly like a vacuum, and food can be ground with maximum chewing force without feeling pain.

Furthermore, making the prosthesis compatible with the soft tissues in the mouth has an incredibly positive impact on facial aesthetics. Sunken cheeks, thinned lip structures, and an aged facial profile are restored through a properly supported prosthesis, giving the patient a much younger and more dynamic expression. Because prostheses seated on a correct foundation do not create improper pressure centers, they also delay the long-term resorption (melting) of the underlying jawbone. Once these surgeries are performed, they extend the life of the produced prosthesis for years and reduce the patient's adaptation period to seconds.

Frequently Asked Questions

They will definitely go away. The main purpose of pre-prosthetic surgeries is to smooth the sharp protrusions in the jawbone and remove flabby tissues. Since a flat and healthy foundation is obtained after the procedure, your prosthesis will sit on the tissues fully and painlessly.

Quite the contrary; if a short tongue tie (ankyloglossia) restricts speech or the pronunciation of letters, opening the tie with a laser increases the mobility of the tongue, correcting and relaxing speech. The procedure is very simple and has no negative effect on your speech.

Although healing takes a few days in soft tissue procedures, when bone correction (alveoloplasty) is performed, it is generally best to wait 3-6 weeks for the tissues to take their final shape and the prosthesis measurement to become clear to get the healthiest result. During this time, your temporary prosthesis is covered with a soft inner lining and offered for your use.

No, almost all pre-prosthetic surgical preparations are completed in our clinic environment, in the dentist's chair and under local anesthesia (numbing only that area), in a short time without the need to stay in the hospital.

When a Dental Laser is used in soft tissue procedures such as muscle and tie cutting (frenectomy), since bleeding is stopped instantly, most of the time there is not even a need for stitches, and healing after the procedure is extraordinarily fast.
