Long-term care and maintenance of dental implants and fixed prostheses All-on-4 / All-on-6

Dental implants and fixed prostheses type All-on-4 / All-on-6 can accompany you for many years, but only if they are cared for properly: specific daily hygiene, regular check-ups and control of risk factors such as smoking, diabetes or bruxism. In this guide we answer the most frequent questions people ask about AIs: how long they last, how to clean them, how often they need maintenance, what happens if I smoke and what are the warning signs.

How long can implants and All-on-4 / All-on-6 prostheses last?

Under ideal conditions, a well-integrated and maintained implant can last for decades. In practice, we are talking about:

• Very high 10-year success rate with good diagnosis and maintenance.

• The fixed prosthesis (the “screw-retained denture”) may require adjustments, repairs or tooth/acrylic replacement over time, even if the implants continue to function.

Factors influencing duration:

• Bone quality and initial diagnosis.

• Plaque control and daily cleaning.

• Tobacco, uncontrolled diabetes and bruxism.

• Periodic maintenance assistance.

Do they clean like normal teeth?

Not exactly. Implants and fixed prostheses require specific tools and angles to clean well around the abutments and under the prosthesis.

Basic daily routine

1. Brushing 2-3 times a day

   • Soft bristle brush, small movements around the gums and abutments.

   • In All-on-4/6 type prostheses, insist on the gingiva-prosthesis junction.

2. Interproximal brushes or special brushes for implants

   • In areas where there are spaces, they allow cleaning where the normal brush does not fit.

3. Special or superfloss

   • In some fixed prosthesis designs it is possible to pass underneath, in others alternatives are used.

4. Oral irrigator (optional but very useful)

   • It does not replace the brush, but helps to remove debris under the prosthesis and around the implants.

5. Alcohol-free mouthwash

   • It can help reduce bacterial load, especially in patients with periodontal or peri-implantitis risk.

In the control appointment we teach you which tool to use in each area; it is part of the protocol of integral dental treatment in CDMX: complete rehabilitation step by step.

How often should I go for maintenance if I have implants or All-on-4?

It depends on your level of risk, but as a general rule:

• Healthy patient, without tobacco or previous periodontal disease:
  every 6 months for check-up and professional cleaning.

• Patients with a history of periodontitis, smokers or diabetics:
  every 3-4 months is the most prudent.

In these quotations it is reviewed:

• Plaque and calculus accumulation around implants.

• Gum condition and probing depth (to detect peri-implantitis in time).

• Adjustment of screws, contacts and occlusion (how teeth collide).

• Integrity of the prosthesis: acrylic, teeth, fractures or wear.

Smokers, diabetics and bruxists: special care

Smokers

• They increase the risk of peri-implantitis and reduced healing.

• We often recommend more controls and detoxification programs.

• In some cases we advise minimizing or quitting smoking before All-on-4/6.

Diabetics

• It is key to have diabetes under control before surgery and during maintenance.

• We recommend strict hygiene controls and more frequent visits.

Bruxers (clenching or grinding)

• They almost always need customized night guarding.

• They require frequent revision of contacts to avoid overloads that may loosen screws or fracture acrylic/ceramic.

To see how we handle these contexts in complex cases, you can review:

What happens if I don’t take good care of my implants?

The main risks are:

• Peri-implant mucositis
  Inflammation of the gum around the implant, reversible if prompt action is taken.

• Peri-implantitis
  Loss of bone around the implant. If it progresses, it can compromise stability and force the implant to be removed.

• Loosening or fracture of screws and components
  Due to excessive load, poor hygiene or lack of adjustments.

• Bad odor and “dirty” sensation
  Due to accumulation of plaque and food under the prosthesis.

Most of these problems are manageable if caught early at maintenance appointments.

Warning signs: when should I go before my scheduled appointment?

You should contact your clinic as soon as possible if you notice:

• Persistent bleeding when brushing around the prosthesis.

• Pain or localized pressure sensation in one of the implants.

• Mobility or “play” of the prosthesis or of any tooth on the implant.

• Constant bad odor or bad taste that does not improve with hygiene.

• Redness, swelling or pus discharge near an abutment.

Although it does not hurt much, it may be the beginning of a peri-implantitis that should be treated as soon as possible.

I live outside of CDMX or in another country, how do I organize the maintenance?

Frequently asked question in dental tourism: “If I go from USA/Canada, how do I follow up?”

In general:

1. First phase in CDMX

   • Implant surgery and placement of temporary or definitive prosthesis, depending on the case.

   • Detailed explanation of hygiene and immediate care.

2. Combined maintenance plan

   • Key checkups at La Clínica Dental when you come to CDMX (e.g., at 1 or 2 years).

   • Intermediate check-ups with a trusted dentist in your city, following our written instructions.

3. Digital communication

   • Photos, radiographs and video calls to monitor progress between face-to-face visits.

Is implant maintenance painful?

Maintenance should not be painful. It can be somewhat annoying depending on the amount of plaque build-up or the condition of the gums, but:

• Topical or local anesthetics may be used on sensitive areas.

• The cleanings are performed with instruments adapted to implants in order not to damage the surface.

If you have a fear of the dentist or a history of bad experiences, it is worth reading:

How much does it cost to maintain implants and All-on-4/6?

Maintenance is usually much less expensive than the initial surgery. The cost varies according to:

• Number of implants and complexity of the prosthesis.

• If only cleaning and overhaul is done or if adjustments, screw replacement or acrylic/teeth repair is required.

The important thing is to see it as an investment to protect your complete rehabilitation.
