Cases shared · Lessons learned

A few cases.
A lot to learn.

I have placed implants for many years, and I have made my share of mistakes. Some cases went better than I deserved; some taught me things I would rather have learned another way. No surgery is without risk, and every patient who trusts us is a privilege.

This site shares real cases, the good and the difficult, so colleagues can learn from them as I learned from others. These are not the only ways to treat these problems, and often not the best. They are simply what I did, what I saw, and what I would do differently.

A shared structure

How each case will be written.

I’ll use the same shape for each story, so the thinking and the uncertainties are there to see. This is a guide to what’s coming, not a patient case.

Problem
What I found, with the relevant X-ray, three-dimensional scan or photograph to help explain it.
Plan
The options I considered, and why I chose this approach in this case.
Surgery
The steps I took, with a sequence of images where that helps tell the story.
Result
What I saw afterwards, with an X-ray and mouth-only photograph where available. I’ll explain the risks, how they were discussed and managed, and what remains uncertain.
Lessons
What I would repeat, and what I would change. Colleagues may choose differently, and they may be right.

Every case will explain the risk, how it was explained and managed, and what I would repeat or change. This is one way to manage it. Colleagues may choose differently, and they may be right.

About Dr Droo

I'm Andrew. I completed my BSc in Biochemistry at the University of British Columbia in 1996 and my DMD there in 1997, followed by hospital dentistry in Vancouver. I later became a Diplomate of the International Congress of Oral Implantologists (ICOI). From 2000 to 2020, I served as an Associate Professor.

No treatment is without risk. I have made mistakes along the way, and I am grateful to the teachers, teams and patients who have helped me learn from them.

I also give back through children's dental charity work, alongside colleagues and volunteers. It is a blessing to be able to help.

Consent, privacy & context.

Case images will be de-identified, mouth-only and used with patient consent. No patient images are displayed yet. Clinical photographs will be cropped to teeth and gums inside the retractor, without lips, skin or background. Radiographs will have names, dates and other identifiers removed, retaining the L/R marker. Hidden image data will be stripped and files renamed. Images and text require consent checks and Droo’s approval before publication; identifying patient details will not be included.

These are stories about individual cases, not advice about anyone else’s care or instructions to follow. Each has its own circumstances and limits. Sharing a case does not remove privacy obligations or the need for local advertising-compliance review.
