The first 48 hours: flying home
Swelling after implant placement peaks at 48 hours and then begins to resolve. Flying during this window – on day two or three post-placement – is not recommended. The pressure changes during ascent and descent, combined with reduced circulation in a seated position, increase the risk of prolonged swelling and discomfort, particularly for upper jaw implants where sinus proximity is a consideration.
Most SmileJet partner clinics in Hoi An schedule the post-operative check on day five or six. Flying home the day after this check – day six or seven – is the standard recommendation. If you are on anticoagulant medication, inform your airline at booking; most will not require a medical letter for routine anticoagulation but it is worth noting in your booking record. For upper jaw implants near the sinus floor, your clinician will discuss any specific flying restrictions at the post-op check.
Week 1–2 at home
The first two weeks at home are the most closely managed phase of aftercare. Maintain a soft food diet – nothing requiring significant biting force on the implant site. Avoid drinking through a straw, which creates negative pressure in the oral cavity and can disturb the clot and early healing tissue. Do not smoke; smoking impairs angiogenesis and significantly increases early implant failure risk.
Rinse with 0.12% chlorhexidine gluconate solution (available over the counter in most pharmacies) twice daily, after brushing. Swelling and bruising in the first week are normal; significant bruising of the cheek or under the jaw line is common with mandibular implants. A low-grade ache at the site for the first week is expected. What is not expected, and warrants immediate contact with your Hoi An clinic: pulsing pain that does not respond to paracetamol, visible pus from the implant site, or fever above 38°C.
Week 3–12: osseointegration window
Once swelling and acute discomfort have resolved – usually by the end of week two – the implant enters the osseointegration phase. Bone cells grow into the implant's titanium surface over approximately 8–12 weeks. There is little to do during this period beyond maintaining oral hygiene and protecting the site from loading.
Clean interdentally with soft interdental brushes sized to fit the gap around the healing abutment. Do not use the implant site for chewing hard food. A follow-up periapical X-ray at week 12, taken by your local dentist, will confirm whether osseointegration is progressing as expected. Bring the radiograph report back to your Hoi An clinic – most SmileJet partner clinics review these remotely and will advise on timing of the crown fitting trip.
Finding a local dentist for follow-up
Most local dentists are comfortable monitoring an osseointegrating implant placed overseas, provided they have the necessary documentation. What to bring: your treatment notes (in English – your Hoi An clinic will provide these), the implant brand and model (e.g., Osstem USII SA, 4.0 x 10 mm), the batch number for the implant and abutment, and any post-operative instructions. You do not need to find a dentist with specific experience in Vietnamese implant systems – Osstem and Dentium are internationally certified brands used in Australian, UK, and New Zealand practices, and the monitoring protocol is identical regardless of where the implant was placed.
Request a periapical X-ray at the 12-week visit. If your local dentist is unfamiliar with the specific implant system and has questions, your Hoi An clinic's English-speaking coordinator can liaise directly.
Remote follow-up with your Hoi An clinic
SmileJet partner clinics in Hoi An offer remote radiograph review as a standard part of the aftercare protocol. Once your 12-week periapical X-ray is taken by your local dentist, request a digital copy (JPEG or DICOM) and send it to your Hoi An clinic coordinator via the contact details in your treatment notes. The clinician will review it and confirm whether healing is on track and when to plan the crown fitting return trip.
Questions to ask at the 12-week remote review: Is bone density at the implant collar consistent with expected osseointegration? Is there any peri-implant radiolucency? Is the healing abutment position satisfactory? Has the lab already taken initial measurements for the crown prosthetic? These questions give you a clear picture of whether Trip 2 timing is flexible or urgent.
Warning signs: when to act immediately
The following symptoms after the first two weeks of initial healing require immediate action: persistent pulsing pain at the implant site that was not present in week one; implant mobility (the implant should feel completely fixed – any movement is abnormal); discharge or pus from around the healing abutment; fever; or significant swelling returning after it had previously resolved.
These presentations are rare in the SmileJet listed partner clinic cohort but they do occur. If you experience any of them: contact your Hoi An clinic coordinator immediately (most respond within 12 hours across time zones); see your local dentist or an oral surgeon within 48 hours; do not wait for a routine appointment slot. In rare cases of implant failure, early intervention – removal and bone grafting – preserves the site for re-implantation. Delayed presentation reduces options significantly.
The second trip: crown fitting
Crown fitting typically takes place 3–6 months after implant placement, once the 12-week X-ray confirms satisfactory osseointegration. The crown fitting trip to Hoi An is shorter than Trip 1 – usually 4–5 days. Day one is the impression (or intra-oral scan), days two to four cover lab fabrication, day four or five is fitting and final check. The crown appointment itself is a comfortable procedure – no anaesthesia is typically required for a straightforward single crown fitting on a stable implant.
Some patients arrange for the crown to be fabricated by a local laboratory in their home country using the implant specs from Hoi An, avoiding the return trip entirely. This is feasible but requires close coordination between your local dentist, the local lab, and your Hoi An clinic on abutment specifications and emergence profile. Discuss this option with your SmileJet coordinator before Trip 1 if you know a return trip will be difficult.
