Meet Your All on 4 & Dental Implant Specialists

Dr. Ralf F. Poineal, DDS
Prosthodontist & Dental Implant Specialist

Some dentists have experience. Dr. Ralf Poineal has a career — nearly four decades of it — dedicated entirely to one of dentistry's most demanding specialties. A prosthodontist trained at Emory University, where he earned both his DDS and his specialty certificate, Dr. Poineal has spent the better part of his professional life doing exactly what All on 4 demands most: rebuilding smiles from the ground up with surgical precision and lasting results.

For over 25 years, he owned and operated multiple private prosthodontic practices across two states, focusing on full-mouth fixed and removable implant reconstructions. That kind of ownership experience means he has seen — and successfully treated — virtually every clinical scenario imaginable. He brings that same depth of judgment to every All-on-4 case today, combining CBCT-guided diagnostics, fully digital workflows, and implant-supported prosthetics to deliver outcomes that are accurate, aesthetic, and built to last.

Before dentistry, Dr. Poineal served his country as a U.S. Army medic — an experience that shaped the calm, steady, patient-first approach his patients have come to rely on. He has also been invited to speak at the Emory University Dental Symposium on topics ranging from TMJ dysfunction to advanced prosthodontic techniques, a testament to the respect his peers have for his expertise.

For patients considering All on 4, experience is everything. Dr. Poineal doesn't just perform this procedure — he has spent nearly 40 years mastering the science behind it. His patients don't just leave with new teeth. They leave with the confidence that comes from being treated by one of the most experienced restorative minds in the field.

Dr. Laurențiu Popa

Dr. Laurențiu Popa brings a level of expertise to All on 4 care that is genuinely rare — and it starts long before dental school. Before becoming a dentist, he spent years as a master dental ceramist and laboratory technician, hand-crafting crowns, bridges, veneers, and implant restorations from start to finish. That bench experience gives him something no classroom can teach: an intimate, hands-on understanding of exactly how a great restoration is made.

He graduated from dental school in 2012, finishing 3rd in a class of 141, then pursued some of the most rigorous specialty training available in the United States. He completed an Advanced Prosthodontic Preceptorship at UCLA, followed by a full Prosthodontics Residency at the University of Alabama at Birmingham — gaining deep expertise in full-mouth reconstruction, implant-supported prosthetics, fixed and removable restorations, and surgical implant placement. He then went further, completing a Maxillofacial Prosthodontics Fellowship, where he treated patients with cancer, congenital craniofacial disorders, and complex trauma — cases that demand the highest level of problem-solving, precision, and care.

That fellowship-level training is what separates Dr. Popa. Most implant dentists place implants. Dr. Popa rebuilds entire oral systems — integrating surgical planning, prosthetic design, and laboratory science in a way that very few clinicians in the country can. He is fully proficient in both digital and analog workflows, including 3D-guided surgery, digital smile design, and advanced occlusal rehabilitation.

For patients choosing All on 4, Dr. Popa's unique combination of laboratory mastery, surgical skill, and prosthodontic excellence means every detail of your new smile — from the fit and function to the final aesthetic — is in exceptionally capable hands.
