For 25 years, Leon Dolling had been relying on an upper removable denture. Like many patients who wear dentures for decades, Leon faced a significant challenge: progressive bone resorption in the upper jaw. By the time he reached out to Sydney Top Dental, he was ready for a permanent change-a fixed, long-term solution that would restore his confidence and his ability to eat without hesitation.
The Challenge: Severe Bone Loss
At 75, Leon’s primary concern was the lack of stability and the aesthetic limitations of his removable denture. However, his clinical evaluation revealed significant bone loss, making conventional dental implants impossible without extensive, time-consuming bone grafting procedures.
Leon needed a specialist who could offer an immediate, effective alternative. That is where the expertise of Dr. Nguyen Ngoc Hai (DDS, MSc)—founder of the ZAGA Center in Ho Chi Minh City—came into play.

The Precision Approach: Zygomatic Implants
Dr. Hai recognized that to avoid the long, painful process of bone grafting, a Zygomatic Implant approach was the gold standard for Leon. Zygomatic implants are longer than traditional implants and are anchored into the dense zygomatic (cheek) bone, bypassing the need for an existing ridge of jawbone.
The Surgical Plan:
- Upper Jaw: To ensure maximum stability, Dr. Hai placed 2 Zygomatic Implants in combination with 4 conventional implants. This hybrid framework provides a solid, long-lasting foundation for a full-arch fixed prosthesis.
- Lower Jaw: A single implant was strategically placed to support his remaining dentition and help preserve the surrounding bone structure.

From Removable to Fixed: The 72-Hour Transformation
One of the most rewarding aspects of our work at Sydney Top Dental is the speed at which we can restore a patient’s quality of life. Thanks to our advanced digital treatment planning and the seamless coordination with our in-house dental laboratory, we were able to provide Leon with his fixed provisional teeth just 72 hours post-surgery.
Within one week of the procedure, Leon’s transformation was undeniable. He had transitioned from a lifetime of removable dentures to a secure, natural-looking, and functional fixed smile.
