Vertical Ridge Augmentation Part 3: Vertical Distraction Osteogenesis (DO)

Vertical Ridge Augmentation is a procedure used to enhance the height of the bone ridge in a patient’s jaw. This technique is employed to address bone deficiencies that may be encountered during dental implant placement. Part 3 of this process involves Vertical Distraction Osteogenesis (DO), which is a technique used to gradually elongate the bone and create more space for the augmentation.

What is Vertical Distraction Osteogenesis?

Vertical Distraction Osteogenesis (DO) is a surgical method that allows for controlled bone growth, specifically in the vertical dimension. This technique enables the creation of new bone tissue, resulting in an increased height of the bone ridge. This is accomplished by gradually stretching the bone using a specialized device over a period of time.

The Process of Vertical DO

The Vertical DO procedure begins with a small incision made in the bone ridge. Then, a device, known as a distractor, is inserted. The distractor consists of two parts: one that is attached to the bone and another that is located externally. These two parts are connected through a screw-like mechanism that, when activated, facilitates the gradual separation of the bone.

Once the distractor is in place, controlled pulling forces are applied to the bone ridge. These forces are exerted in a direction that stimulates the formation of new bone tissue, allowing for the gradual expansion of the ridge. The amount of distraction is carefully monitored and adjusted by the dental professional to ensure optimal results.

Advantages of Vertical DO in Vertical Ridge Augmentation

Vertical Distraction Osteogenesis offers several advantages in the context of Vertical Ridge Augmentation:

1. New Bone Formation

The gradual stretching of the bone ridge stimulates the production of new bone tissue, resulting in an increased height of the ridge. This new bone formation provides a solid foundation for dental implants or other dental procedures, ensuring long-term stability and success.

2. Avoidance of Grafting Procedures

Vertical DO eliminates the need for bone grafting, which is often required in conventional ridge augmentation procedures. This reduces the complexity of the treatment and minimizes the potential risks associated with grafts, while still achieving the desired bone height.

3. Improved Esthetics

By increasing the height of the bone ridge, Vertical DO contributes to improved esthetics. The enhanced bone structure allows for the placement of dental implants at the ideal position, resulting in a natural and harmonious appearance of the final restoration.

4. Predictable Results

Vertical Distraction Osteogenesis has demonstrated high success rates in achieving predictable and stable outcomes. The controlled nature of bone growth allows for precise planning and execution, ensuring that the desired bone height is attained.


In conclusion, Vertical Ridge Augmentation Part 3 involves Vertical Distraction Osteogenesis (DO), a technique that gradually elongates the bone to create more space for augmentation. This process stimulates the formation of new bone tissue, providing a strong foundation for dental implants or other dental procedures. Vertical DO offers advantages such as new bone formation, avoidance of grafting procedures, improved esthetics, and predictable results. By incorporating Vertical Distraction Osteogenesis into Vertical Ridge Augmentation, dentists can achieve optimal bone height and ensure successful treatment outcomes.

FAQs (Frequently Asked Questions)

1. Is Vertical Distraction Osteogenesis a painful procedure?

While there might be some discomfort during the recovery period, the procedure itself is performed under anesthesia to ensure a pain-free experience.

2. How long does it take to complete Vertical Distraction Osteogenesis?

The length of the treatment varies based on individual cases, but it typically takes several months for the bone to elongate to the desired height.

3. Are there any risks or complications associated with Vertical DO?

As with any surgical procedure, there are potential risks, such as infection or device-related issues. However, complications from Vertical Distraction Osteogenesis are rare when performed by an experienced dental professional.

4. Can Vertical Distraction Osteogenesis be combined with other dental procedures?

Yes, Vertical DO can be combined with other dental procedures, such as dental implant placement or bone grafting, to address multiple aspects of a patient’s oral rehabilitation needs.

5. How long will the results of Vertical Ridge Augmentation with Vertical DO last?

With proper oral hygiene and regular dental care, the results of Vertical Ridge Augmentation with Vertical DO can last a lifetime. Dental implants placed on the augmented ridge have long-term success rates comparable to natural teeth.
