“My training in biological dentistry with Mario has not only stood out for being interesting and very comprehensive from a clinical standpoint. The human touch and completely personalized treatment I have received from him afterward—always willing to resolve any doubts from daily practice that I’ve brought to him—makes it totally recommendable. Training with Mario means learning 21st-century dentistry”

“Training with Dr. Mario Parra has been a transformative experience. His approach to biological dentistry goes far beyond technique: it integrates health, science, and awareness in a profound and coherent way. He is not only a reference in the field, but also a generous teacher who shares his knowledge with clarity, ethics, and passion. Thanks to his teachings, I have been able to apply safer and more biologically respectful protocols for my patients, achieving truly remarkable results.”

“I had the opportunity to take a course in Biological Dentistry – Swiss Biohealth Concept, with Dr. Mario Parra at the BDS clinic. The experience was truly enriching, not only because of the quality of the content, but above all due to the way Dr. Parra conveys his knowledge.
He is a close, clear, and highly dedicated trainer with his students. He is always willing to answer questions and make sure we understand every detail.
Later, I completed a clinical stay at his practice, and once again I found in him a generous, patient, and committed professional, as well as a wonderful team that makes you feel as if you have always been part of them.
Without a doubt, I recommend Dr. Mario Parra as a trainer in Biological Dentistry, both for his great human quality and for his excellent ability to teach and share his experience”

“It was in Switzerland, at the SDS clinic, where I first heard about Mario, a colleague trained in his BioHealth method and Ambassador for excellence in ceramic implantology, who was also teaching in Spain. When I returned, I reached out to him for more information and, without hesitation, enrolled in his course. Since then, and having taken it twice, I can confidently say that any colleague who wants to level up should join. You not only gain knowledge that is often hidden in our country, but you also become part of the BDS family in La Nucía, a group led by Dr. Mario Parra — an outstanding professional and, above all, a wonderful person.
I encourage you to embrace Biological Dentistry!
Warm regards,
Antonio José Moreno”

“Excellent consulting experience with an outstanding biological dentist
At the beginning of my implantology journey with the SDS concept, I worked closely with Dr. Mario Parra and received exceptional support. He takes the time to provide thorough explanations, answers questions competently and reliably—usually within an hour. Even on weekends, he was attentive and willing to respond promptly, despite personal commitments. This reliability impressed me greatly and gave me a strong sense of security.
What truly sets him apart are his practical insights and tips for handling complications, as well as his solid advice on patient management. These aspects are central to the SDS concept, and his expertise helped me plan treatments with confidence and guide patients competently.
His online consulting and mentoring services are professional, empathetic, and clear in communication. Although I only interacted with him at the time through a messenger service, using voice messages and direct, personal communication, I felt that his dedication and engagement in online support reflect the same care and reliability as in personal contact. He creates a trusting learning environment where learners feel safe to ask questions and deepen their knowledge.
I recommend his services to anyone who wants to pursue qualified training with a holistic, evidence-based approach in biological dentistry. I also recommend him to anyone seeking concrete answers to everyday clinical practice. His respectful and supportive attitude made me feel valued throughout my learning process, and I always felt comfortable turning to him with questions, without fear of judgment for my supposed “mistakes.”

Thank you, Mario.

“As a dentist, I had the opportunity to make hospitations at the BDS Clinic on several occasions. The clinic is very well positioned in the field of biological dentistry. The concept is professional and tailored to each patient from the very first visit to the last.
Mario is a very empathetic dentist who takes a great deal of time with his patients. As a colleague, despite his busy schedule, he devoted plenty of time to explaining the treatment processes in detail, from planning through to completion.
I greatly value Dr. Mario as a person and his expertise as a dentist.
I am especially grateful for his online mentoring consultations in the field of ceramic implants. His expertise and the online exchange using imaging techniques have significantly advanced my knowledge in biological dentistry.
I can highly recommend him both as a patient and as a dentist!”

“NexaCore’s online consulting services truly make a difference for healthcare professionals, especially dentists. With their guidance, we have successfully implemented the principles of biological and integrative dentistry in our practice while also staying up to date through continuous training.

Throughout the process, I felt fully supported, which allowed us to take a new direction in our clinic and deliver integrative services with a highly positive impact on our patients.

What makes NexaCore stand out is not only the expertise but also the clarity it brings in a profession that often feels overwhelming — between the constant demands of clinical work, the need to differentiate, and the challenge of staying current with new approaches.

I am deeply grateful to Dr. Parra for his constant support, his online mentorship, and for his enriching visit to personally present the scope of NexaCore’s services. Without a doubt, it has been a transformative experience.”

“The clinical stay for biological dentistry training with Dr. Mario Parra was unique. Not only for everything he taught us, but for how approachable and human he is. It was very comprehensive training. We got to know his team closely. Everyone was aligned in Biological Dentistry. Thanks to the 5 days I spent hands-on with him, I was encouraged to start implementing the new concepts in my practice. I´ve already signed up in Switzerland for the Ceramic Implants course to take another leap in Biological Dentistry and get closer to transmitting health to my patients. For sure all kind of biological dentistry training offered by Dr. Parra is highly recommendable. Thank you Dr. Parra for inspiring other professionals and sharing all your knowledge.”
