Translating science into predictable esthetic implant care

On the occasion of his recent peer reviewed publications with focus on single tooth rehabilitation in the esthetic zone1-2, we sat down with Dr. Vincent Donker to discuss his latest research. With a strong scientific track record in implant dentistry, Dr. Donker reflects on these studies, their clinical relevance, and how digital workflows continue to shape evidence based care in the esthetic zone.

Dr. Donker, what clinical challenges in the esthetic zone led you to explore both immediate implant placement and placement after ridge reconstruction?

In daily practice, the esthetic zone is where expectations are highest and tolerance for complications is lowest. The key challenge is that patients often present with very different starting points: some have relatively intact bone and soft tissues, while others already show collapse or defects by the time the tooth fails.
We wanted to understand how far we can safely go with immediate implant placement, and where biology suggests we should slow down and rebuild the alveolar ridge first. Exploring both approaches allowed us to observe when immediate treatment is predictable, and when a staged reconstructive approach offers better outcomes.

How did the digital workflow support more predictable decision making across diverse anatomical situations?

The digital workflow allowed us to see the full picture before treating the patient. By combining 3D bone imaging with intraoral optical scans, we could plan the desired prosthetic outcome first and then position the implant exactly where it supports both aesthetics and biology. This was especially helpful in borderline situations.
Instead of relying on experience alone, we could objectively assess whether primary stability and soft tissue support were achievable. In that sense, DTX Studio Implant and digital planning became a decision making tool, not just a technical aid.

What did these studies reveal about biology, implant stability, soft tissue behavior, and early risks?

The studies highlighted a clear biological boundary. When buccal bone defects remain within 5 mm, immediate implant placement can be predictable if adequate stability and soft tissue support are achieved. In our study, these defects were managed using a combination of autogenous bone and a bone substitute to support the buccal contour.
Once defects exceed this level, stability becomes less reliable and early biological and esthetic risks increase. In such cases, a staged approach with alveolar ridge reconstruction was used.
We also observed that soft tissue changes occur early and then stabilize. Minor recession is almost unavoidable, but when the implant is correctly positioned and supported by a well designed temporary crown, tissues tend to remain stable over time.
The early healing phase is therefore the critical window during which most risks occur. This is consistent with our experience.

How did working with a complete Nobel Biocare system influence confidence and consistency in your clinical workflow?

Having a fully integrated system reduced variability at every step. The planning software, implant design, surgical components, and restorative parts were all designed to work together. That consistency meant fewer surprises during surgery and restoration.

Based on the outcomes, what defines a truly premium, science based solution in complex esthetic cases?

A premium solution is not about speed. It is about scientifically proven, long term durability. That means stable bone levels, healthy soft tissue, and patients who feel confident that their smile will remain stable over time.
Our research team has more than a decade of clinical and scientific experience, with multiple long term publications on implants in the esthetic zone. The current studies build on this foundation, now incorporating the full benefits of a digital workflow to further improve precision and consistency.
Science based care also acknowledges limitations: sometimes the best solution is not the fastest, but the one that respects tissue healing, works within biological boundaries, and ultimately reduces risk.

How should clinicians use evidence from these studies when deciding between immediate implant placement and a staged reconstructive approach?

The evidence supports immediate placement in carefully selected cases, not as a default option. Clinicians should evaluate bone volume, soft tissue phenotype, and the ability to achieve stable implant anchorage.
When these factors are favorable, immediate treatment can deliver excellent outcomes. When they are not, staged reconstruction remains the more predictable and biologically sound choice.

Looking ahead, how do studies like yours help shape the future of evidence based implant dentistry and improve clinical predictability for both patients and clinicians?

Clinical studies help move implant dentistry away from anecdotal success stories toward measurable outcomes that matter to both clinicians and patients. By combining clinical data, esthetics, radiographic stability, and patient experience, we achieve a more complete definition of success.
Ultimately, this improves predictability, supports informed consent, and helps clinicians choose treatments that are not only possible, but genuinely reliable.
