Preprosthetic Surgery

Dental prostheses, such as dentures, may not fit properly if patients have sustained significant bone loss, gum recession, or other problems. Preprosthetic surgery is any form of oral surgery that helps prepare the dental arch to receive a restoration. Depending on the unique needs of the individual, this treatment may involve adding bone or gum tissue, or smoothing the alveolar ridge prior to denture placement.

At the Wisdom Specialist Centre, Dr Zoud performs preprosthetic surgery to ensure that patients enjoy a comfortable, snug-fitting restoration. With years of expertise, he delivers high-quality care to every individual who walks through our door.

Benefits of Preprosthetic Surgery

This type of surgery offers a number of advantages. For example, preprosthetic surgery:

Improves the fit of your denture and reduces the risk for decay, gum disease, and bad breath

Boosts overall wellness by improving chewing function

Enhances your appearance through a snug, well-fitting prosthesis

Determining Candidacy

Generally, candidacy for preprosthetic surgery is determined during the initial denture consultation. If your dentist notices irregularities in the shape or contour of your bone ridge, he or she may recommend this preliminary procedure.

Qualifying patients must be healthy enough to undergo oral surgery. They should be free from any medical condition that could have a negative impact on healing.

Types of Preprosthetic Surgery

There are several types of procedures that can improve the fit of a denture. The one that’s right for you depends on your unique needs.


If the bone ridge is uneven, a denture will not fit properly. It will likely shift, wobble, and slip when you’re trying to eat or speak. An ill-fitting denture can also cause uncomfortable sores or lesions. Alveoloplasty smooths the bone ridge so that the denture fits snugly against the gums.

Removal of Excess Bone

Small bony irregularities are normal and are not a cause for concern. However, large areas of excess bone tissue can affect the fit of your denture. Dr Zoud can remove excess bone tissue during an oral surgery procedure to ensure that your denture fits well.

Removal of Excess Gum Tissue

If the gum tissue is uneven, or if there is simply too much of it, your denture will not fit properly. Dr Zoud can remove excess gum tissue to address this problem. Gum surgery is typically less invasive than procedures that target excess bone.

Ridge Augmentation

Once tooth loss occurs, the bone ridge begins to shrink. If this atrophy continues, it can result in an ill-fitting denture. During a ridge augmentation procedure, Dr Zoud adds bone grafting material to the areas of deficiency. This will fill in the sunken-in areas of the jawbone and create a solid foundation for your denture.


It is common to remove problematic teeth prior to denture placement. In addition to removing damaged or decayed teeth, it’s also important to extract any teeth that could interfere with the fit of your prosthesis, such as impacted or misaligned teeth.


Sometimes the area where the lip meets the gums may interfere with a proper denture fit. In these cases, your oral and maxillofacial surgeon can actually alter the position of the associated tissues and muscles with a procedure called vestibuloplasty.

Healing and Recovery

Your recovery time depends on the type of procedure necessary. Most patients have slight bleeding, swelling, and discomfort for a few days. These side effects can be successfully managed with medications. It’s important to follow the post-operative guidelines provided by our team. Doing so can help you enjoy a speedy, successful recovery.
