Dr. Nikolaos S. Karatzeas

Karatzeas Dental Care Clinic, Kalamata

Digital dentistry is transforming daily implant treatment - not by changing the biological fundamentals, but by making workflows more precise, efficient and predictable when protocols are followed consistently.

In this interview from our DESS® Clinical KOL Interview Series, we talk to Dr. Nikolaos S. Karatzeas, implantologist, oral surgeon and prosthodontist, about the trends that are most influencing treatment outcomes today, where clinicians still face challenges with guided workflows, and what really contributes to long-term predictability at the component and tissue level.

Key insights

Digital dentistry is one of the strongest drivers behind increased predictability today, with simpler workflows and fewer errors when protocols are respected.

Clinical quality still relies on correct execution of protocols, anatomically guided decisions and careful planning.

Guided surgery can simplify complex cases, but accurate matching between intraoral scans and CBCT/DICOM files remains a common challenge.

Long-term success depends on components that respect the biology of the peri-implant tissues, with stable interfaces and good biocompatibility.

1. Background and vision

How would you describe in one minute your clinical focus today?

In today's dentistry, the integration of technology and the availability of different tools means that our treatments are becoming more predictable. In implantology and prosthodontics, there has been a huge evolutionary leap, both in terms of digital and clinical protocols.

What has changed the most in implant dentistry over the last 10-15 years?

If we look back 10-15 years, implant dentistry has not changed dramatically - the basic principles are still the same. What has evolved is the surgical and manufacturing part of implant protocols, which allows us to achieve better clinical outcomes for patients.

"The fundamentals are still the same - what has evolved is the surgical and manufacturing part of the implant protocols."

2. trends and predictability

Which trend is having the biggest impact on treatment outcomes right now - and why?

One of the biggest trends right now is digital dentistry. It has shown very good clinical results, with simple workflows, fewer errors and fewer tests - contributing to a smoother clinical environment for both practitioner and patient.

In complex cases, what is the key factor that differentiates predictable outcomes from average ones?

Predictability comes from the correct execution of implant protocols and from choosing the right tools and instruments. Anatomy differs between each patient, and these challenges or limitations can be addressed when the clinician has a versatile selection of surgical instruments.

"Predictability comes from correctly executing implant protocols - and from choosing the right tools."

3. digital workflow in daily practice

Where does digital planning give you the most value in daily clinical practice?

Digital planning is one of the most crucial steps for success in implant dentistry. Today, technology allows us to plan more accurately and visualize the end result, ensuring that predictability is in line with clinical expectations.

What are the most common challenges clinicians face when adopting guided surgery or digital workflows?

Guided surgery helps to address surgical difficulties, which vary from clinician to clinician. The real challenge lies in matching intraoral scans with CBCT/DICOM files. Designing a surgical guide that truly helps the clinician achieve maximum potential remains challenging in many cases - especially in edentulous all-on-x workflows.

4. components, interfaces and long-term results

What should clinicians always check at the component and interface level to reduce long-term complications?

Long-term success depends on how well the implant components respect the biology of the surrounding tissues. Clinicians should ensure that the design and fit of the components support tissue health and do not contribute to bone loss or inflammation. A stable interface, precise connections and high biocompatibility are essential - and maintaining healthy peri-implant tissues should always be the first priority.

5. experience with DESS®

What do you value most in a prosthetic solution provider?

Quality and versatility of the components, combined with digital solutions that improve daily dental care.

Where do DESS® solutions make the biggest difference in your practice?

Easy-to-use surgical and laboratory workflows are crucial. Having a company that can offer high-quality implants as well as compatible components for major implant brands contributes to a smooth workflow in the clinic. CAD workflows - including well-organized libraries - help make treatments faster and more predictable.

What one piece of advice would you give to clinicians looking to improve predictability in implant cases?

Stick to implant protocols and human biology for predictable outcomes. Clinical excellence in implantology comes from experience, respect for anatomy and careful treatment planning. A proper treatment plan is the key to long-term success - and every case should be treated with the same passion and care as if it were your first.
