Dental Implant Quality: 10 Questions to Ask Before Treatment

You can see an implant's price at a glance; its quality is much harder to judge. There is a set of questions that works in Hong Kong and Shenzhen alike, and most of the answers can be checked on official websites: is the dentist registered, is the implant registered, will you get the implant details and X-rays, what does the quote include, how do you pay, and who looks after the implant afterwards. Here are 10 questions, each with an official or academic source.

1. Is the dentist registered?

The Dental Council of Hong Kong publishes the General Register and the Specialist Registers, including oral and maxillofacial surgery, periodontology and prosthodontics. The Consumer Council also advises using registered dentists and checking the Dental Council's list (Chinese).

Mainland doctors can be checked through the National Health Commission's physician practice lookup on the national government services platform, by province, name and institution (Chinese). Ask who will actually perform the surgery, not just whose name is in the advert.

2. Is the clinic or hospital licensed?

In July 2026 police and the Department of Health arrested a 72-year-old man at a mainland dental organisation's Hong Kong "consultation office" in North Point on suspicion of practising dentistry illegally (the nature of the premises as reported by Wen Wei Po and the South China Morning Post). The Department of Health urged the public not to use unlicensed dental clinics, to avoid treatment errors, infection and other health risks (RTHK, Chinese).

Mainland medical institutions can be checked on the National Health Commission's national medical institution lookup (Chinese).

3. What brand and model is the implant, and is it registered?

An implant is a medical device. On the mainland you can check it on the NMPA's domestic device registration lookup or imported device registration lookup by product name or registration number (Chinese).

Hong Kong is different. The Department of Health's Medical Device Division says there is currently no specific legislation regulating the manufacture, import, distribution, supply or use of medical devices; a voluntary administrative control system has run since 2004. In July 2025 the government said it was preparing legislation and expected to put proposals to LegCo the following year. So in Hong Kong, the key step is to ask for the brand and model and make sure they go into your record.

4. Will I get the implant details and X-rays?

This is the question most often skipped and the most important for future repairs. The FDI World Dental Federation says dentists must record, and communicate to patients, the characteristics of the implants placed, for maintenance and traceability. Guidance from the Faculty of Dental Surgery of the Royal College of Surgeons of England says the record should include the implant system, type, position and diameter, the prosthetic connection, and X-rays taken after the crown is fitted.

Mainland rules require the name and key technical parameters of implanted devices to be written into the medical record (Article 29, Measures on Clinical Use of Medical Devices), and patients have the right to view and copy their records and imaging (Article 16, Regulations on Medical Disputes).

In practice: before the course ends, get the implant brand, model, diameter and length, abutment type, whether the crown is screwed or cemented, the surgery date and the latest X-rays.

5. What was assessed before surgery?

An implant is more than "putting in a screw". Cambridge University Hospitals (NHS) says the success rate falls to 80–85% over seven years for patients with gum disease, and smokers have a much higher failure rate and are expected to stop at least six months before treatment. The FDI also notes that complications are more common in people with a history of periodontitis.

Worth asking: was gum disease treated first? Is there enough bone, or is a graft needed? Were X-rays or a 3D scan taken, and why? Did the dentist ask about your medical history and medicines?

6. How long is the course and how many visits?

An implant usually needs three to six months to heal, sometimes longer, before the final crown. If an advert promises everything in one day, ask whether that is a temporary tooth, which cases qualify and how many follow-ups remain. The Hong Kong Dental Association has raised concern about adverts claiming "implant in the morning, eat an apple in the afternoon" (RTHK, Chinese).

7. What about sterilisation and the surgical setting?

The Department of Health's code of practice on infection control in dental practice, issued under the Private Healthcare Facilities Ordinance, requires items that can't be reused or sterilised to be disposed of after use, and detachable handpieces to be sterilised after use. The mainland standard WS/T 842-2024 requires implant treatment in a separate surgery and sterile water for cooling and irrigation during implant surgery.

You may not see the sterilisation, but you can ask: is the implant placed in a separate surgical room or a general chair? Are the instruments single-patient and in sterile packs?

8. What does the quote include? Is it in writing?

The Dental Council's code requires clinics to display a notice telling patients of their right to ask for a quotation before treatment, and dentists should give one where substantial fees are involved. Valid consent also needs an explanation of the nature, effect and risks of treatment and the other options, including no treatment.

When comparing quotes, go line by line: implant, abutment, crown, bone graft, 3D scan, temporary tooth, reviews and medicines. See how to read a dental quote.

9. How do I pay, and is a prepayment protected?

The Guangdong Consumer Council's March 2026 dental tips advise choosing qualified, stable providers, being wary of "low-price trials" and "lifetime warranty" claims, and paying for long treatments such as implants and braces in stages, with a written contract, and keeping records, X-rays and dental models (Chinese).

The reason: some mainland dental clinics have closed suddenly. Xinhua, carrying a Legal Daily report, described one chain closure affecting more than 900 patients, some mid-treatment and unable to recover prepayments or records (Chinese). The Supreme People's Court's interpretation on prepaid consumption, in force since May 2025, makes "no refund" clauses invalid and adds protections such as a seven-day refund, but recovering money still takes time.

10. Who maintains the implant afterwards?

Implants need lifelong care. A 2025 systematic review and meta-analysis found that about 63% of adults with implants had peri-implant mucositis and about one in four (25%) had peri-implantitis. Another meta-analysis suggested maintenance at least every 5 to 6 months, adjusted to individual risk. The European Federation of Periodontology recommends a structured supportive care programme once implants are in use.

So decide before you start: where will you have six-monthly checks and cleaning? If a screw loosens, a crown chips or the gum becomes inflamed, who deals with it and at what cost? If you had your implant outside Hong Kong, see can a mainland implant be repaired in Hong Kong?

Claims to be careful about

"No maintenance needed": this contradicts the research and guidance above.
"Implant and eat the same day": only suits some cases; ask if it is a temporary tooth.
"Lifetime warranty": ask what it covers, the conditions, and what happens if the clinic closes.
Price only, no dentist or implant details: ask questions 1–4; if they can't answer or won't put it in writing, think again.

To be fair, the Consumer Council notes that mainland dental regulation differs from Hong Kong's but that the mainland dental profession is also regulated by health commissions at every level (Chinese). These 10 questions apply just as much in Hong Kong: the point is to choose a dentist who answers them clearly.

Frequently asked questions

How can I check that the dentist placing my implant is registered?

In Hong Kong, search the Dental Council's General and Specialist Registers. On the mainland, use the National Health Commission's physician practice lookup by province, name and institution. Ask who will actually perform the surgery.

What information should I get after an implant?

The implant brand, model, diameter and length, abutment type, whether the crown is screwed or cemented, the surgery date and the latest X-rays. The FDI says dentists must record and share implant details, and mainland rules require them in the medical record, which patients may copy.

How long before I have a tooth on the implant?

Healing usually takes three to six months, sometimes longer, before the final crown. Some cases can have a temporary tooth the same day, but not everyone is suitable.

How often should an implant be checked?

Research suggests maintenance at least every 5 to 6 months, adjusted to your risk. Peri-implant inflammation is common, and regular checks catch it early.
