Had an Implant on the Mainland? Getting It Repaired in Hong Kong: Brands, Parts and Records

If you had an implant on the mainland, a Hong Kong dentist can usually follow it up, but how smoothly depends on whether you have the implant details: brand, model, size, abutment type and X-rays. Implant parts are mostly designed system by system, and original components generally fit more predictably. Without records, a dentist may not be able to tell the system from an X-ray alone. Here is why, what to collect, and how to plan long-term care.

How often do Hong Kong dentists see these cases?

According to The Standard, the Hong Kong Dental Association and the University of Hong Kong's Faculty of Dentistry surveyed 216 private dentists and 311 residents. Each dentist saw an average of four patients a month who needed follow-up after dental treatment outside Hong Kong (RTHK, Chinese); implants were involved in 67%, root canals in about 53% and fillings in about 49%. About one in ten residents had had dental treatment in Shenzhen (The Standard). The survey was run by a dentists' body, but it shows that follow-up in Hong Kong is not unusual.

Why does the implant brand matter?

An implant has three main parts: the implant in the bone, the abutment and screw that connect to it, and the crown. Connection shapes and sizes differ between brands, so abutments and screws generally need to come from the same system.

• A systematic review comparing original and non-original abutments concluded that original abutments give more predictable outcomes, while external connections showed some compatibility (Rizvi et al., Journal of Prosthodontics).
• Another systematic review notes that with so many implant systems, it becomes difficult to identify the system from X-rays and clinical examination if previous records are lost (Ibraheem, Diagnostics 2024).

The products selected in the mainland's 2023 national implant procurement include both international brands and domestic manufacturers (Chinese). Clinics stock different systems, and not every clinic has the parts and tools for every system. Sending your implant details to a Hong Kong clinic before booking, and asking whether they can handle it, saves a lot of time.

What to collect after your implant

Information	Why it's needed
Implant brand and system name	Decides which tools and parts are used
Model, diameter, length and position	For matching abutments and assessing bone and gum
Abutment type and connection	Needed to replace a screw or abutment
Screw-retained or cemented crown, and its material	Decides whether and how the crown can be removed
Surgery date; any bone graft	Helps judge healing and risk
X-rays after the crown was fitted (ideally a 3D scan)	A baseline for spotting bone changes later
Records, consent forms and receipts	For follow-up and any dispute

This list comes from professional guidance. The FDI World Dental Federation says dentists must record and communicate implant characteristics to patients for maintenance and traceability. The Faculty of Dental Surgery of the Royal College of Surgeons of England says the record should include the implant system, type, position, diameter, prosthetic connection and post-fit X-rays, plus the cement type and screw-access location for cemented crowns.

What do mainland rules say, and how do I get my records?

• Article 29 of the Measures on the Clinical Use of Medical Devices: for implanted devices, the device name and key technical parameters must be recorded in the medical record (Chinese).
• Article 14 of the Measures on Supervision of the Quality of Medical Device Use: users must keep records for implanted devices, and records of implanted devices must be kept indefinitely for traceability (Chinese).
• Article 16 of the Regulations on the Prevention and Handling of Medical Disputes: patients may view and copy their outpatient records, imaging and consent forms, and institutions must provide copies, charging according to a published fee schedule (Chinese).

So even if you weren't given them, you can apply to the original provider for copies later. It is safest to collect everything the day the course ends, because some mainland dental clinics have closed suddenly, leaving patients unable to recover their records (Xinhua carrying Legal Daily, 2025, Chinese).

In Hong Kong, the Dental Council's code requires dentists to keep records for at least six years. Patients can make a data access request under the Personal Data (Privacy) Ordinance, which must be met within 40 days, and any fee must not be excessive.

What commonly needs attention in Hong Kong?

Problem	What research shows	Usual approach
Loose screw or wobbly crown	5-year screw loosening on single implant crowns: about 3.6% for metal-ceramic and 1.0% for zirconia (Pjetursson et al., 2018)	Screw-retained crowns are easier to remove, retighten or re-screw; parts must match the system
Chipped or broken crown	Same review: 5-year veneer chipping of about 2.8% (zirconia) to 2.9% (metal-ceramic)	May need a new crown, which requires the abutment and connection details
Peri-implant mucositis or peri-implantitis	About 63% of implant patients have mucositis and about 25% peri-implantitis (dos Reis et al., 2025)	Cleaning and treating the inflammation; X-rays to compare bone levels

A "loose implant" can be a loose crown or screw, or the implant itself, and these are handled very differently. See loose implant? A loose crown and a loose implant are different problems.

Planning long-term care

A meta-analysis suggested implant maintenance at least every 5 to 6 months, and Cambridge University Hospitals (NHS) tells patients to see a dentist or hygienist every three to six months for checks and cleaning. If the surgery was done elsewhere, decide early where routine checks will happen and give that dentist your implant details. For full-arch implants, see how to clean and maintain full-arch implants.

Five steps for follow-up in Hong Kong

1. Gather your implant details, X-rays and records (see the list above); if you don't have them, ask the original provider for copies.
2. Send the details to the Hong Kong clinic before booking and ask whether they have tools and parts for that system.
3. At the first visit, expect X-rays and a gum check to find whether the problem is the crown, the screw or the implant.
4. Ask for a written quote that separates the examination, parts, crown and treatment of any inflammation.
5. Once fixed, set up checks and cleaning every 5 to 6 months.

Frequently asked questions

Will a Hong Kong dentist look after an implant placed in Shenzhen?

Yes, but how well depends on having the implant details and X-rays. Send them to the clinic before booking and ask whether they have the tools and parts for that system.

What if I don't know my implant brand?

Ask the original provider for copies of your records and imaging; mainland rules give patients the right to view and copy them. Without records, a dentist may have to infer the system from X-rays and may not be able to identify it.

Can parts from another brand be used in the meantime?

Research shows original abutments generally fit more predictably. Whether a non-original part is suitable is for the dentist to judge case by case; don't assume parts are interchangeable.

How often should an implant be checked?

Research suggests maintenance at least every 5 to 6 months, adjusted to your risk.
