Dental Implant Types: Which One Suits Your Missing Teeth?
There are two main types of dental implant: endosteal and subperiosteal. Endosteal implants sit inside the jawbone and are by far the most common. Subperiosteal implants rest under the gum, on or above the bone, and are kept for people who lack enough bone for a standard implant. Everything else you will see listed online, such as mini, zygomatic, single-tooth or All-on-4, is either a variation on these or a way of using them. This guide explains each one, what decides which suits you, and what to ask at a consultation in Dubai.
TL;DR
- Endosteal implants (placed into the jawbone) are the standard choice when you have enough healthy bone.
- Subperiosteal implants sit on top of the jaw under the gum and are used when bone height is inadequate for an endosteal implant.
- Single, multiple-tooth and full-arch treatments describe how many teeth are replaced, not a different implant material or design.
- Your general health, medications, gum condition and bone volume decide the type, so a scan and a doctor-led assessment come first.
- In Dubai, implant care is covered by Dubai Health Authority clinical guidelines, which set minimum spacing between implants and teeth.

What a dental implant is
The Dubai Health Authority (DHA) defines a dental implant as a prosthetic device made of alloplastic (non-biological) material, placed in the oral tissues beneath the gum or its bone covering, on or within the bone, to support a fixed or removable dental prosthesis. In everyday terms: a small anchor replaces the root of a missing tooth, and a crown, bridge or denture is attached to it.
That definition already hints at why “types” exist. The anchor can go within the bone or on it, and what it supports can be one crown, a bridge or a full set of teeth. Those are two separate questions, and most confusing articles mix them. We keep them apart below.
The two main types: endosteal and subperiosteal
The American Academy of Implant Dentistry names endosteal and subperiosteal as the two principal implant types. A 2024 peer-reviewed review also groups implants by placement into endosteal, subperiosteal and transosteal, which is why you will sometimes see three categories rather than two.
| Endosteal | Subperiosteal | |
|---|---|---|
| Where it sits | Inside the jawbone | Under the gum, on or above the jawbone |
| Typical shape | Screw-shaped post, usually titanium | A custom framework with posts that come through the gum |
| How common | The most common type | Much less common |
| Typical use | Enough healthy bone is available | Bone height is too low for an endosteal implant |
| Planning | Scan, then placement into bone | Scan-based, often custom-designed for your anatomy |
Endosteal implants
Endosteal implants are placed directly into the jawbone, are typically titanium and screw-shaped, and are the most commonly used type. Over the following months the bone grows around the post, which is what holds it firmly. The same 2024 review explains that they dominate modern practice because they are embedded in bone and are the usual solution when adequate bone is available.
If you are healthy, have no active gum disease and your scan shows enough bone, this is almost always the type your dentist will recommend. It works for one tooth, several teeth or a full arch.
Subperiosteal implants
Subperiosteal implants rest on top of the jaw, with posts protruding through the gum. The American Academy of Periodontology says they are generally used when bone height is inadequate for an endosteal implant and the patient cannot wear conventional dentures.
The modern version is not the old hand-made frame. Customised subperiosteal implants use CAD-CAM technology to design the implant for a patient’s specific anatomy. Researchers describe them as a promising option that may involve less morbidity than complex bone-grafting procedures, although the available data are still scarce. Design details matter too: specialists point out that a framework must avoid placing struts over sharp bony edges, to prevent gum tissue losing its blood supply and eroding. That is a reason to choose a clinician who plans from a 3D scan rather than a one-size-fits-all approach.
Endosteal vs subperiosteal in one sentence
If you have enough bone, endosteal is the established route. If you have lost a lot of bone and want to avoid or reduce grafting, a custom subperiosteal design may be discussed as an alternative. The 2024 review frames custom frameworks as an alternative in severe ridge atrophy, not a first choice for everyone.
Transosteal implants
This third placement category is rarely used today. Transosteal implants penetrate the lower border of the jaw and project through the gum covering the toothless ridge. You will meet the term mainly in textbooks and classification tables. In a modern consultation, the realistic conversation is between endosteal and, in specific cases, subperiosteal designs.
Other names you will see: mini, zygomatic and All-on-4
The search results for this topic often list four to nine “types”. Most of the extra names describe a size, an anchoring site or a treatment plan.
- Mini implants are narrower versions of a standard post. They are discussed for situations where space is limited or a denture needs extra stability. Whether a narrow post is appropriate depends on bone and on the forces your bite will place on it, so it is a decision for your dentist after examination.
- Zygomatic implants are long implants anchored in the cheekbone instead of the upper jaw. They are a specialist option for people with severe upper-jaw bone loss and are planned case by case.
- All-on-4 is a full-arch concept: a whole arch of fixed teeth carried on a small number of strategically placed implants. It is a treatment plan using implants, not a separate implant material.
- Screwless implants is a marketing term. The implant itself is still anchored in bone. The name usually refers to how the crown is attached to the post, so ask your dentist exactly what is meant before comparing quotes.
Single, multiple and full-arch: how many teeth you replace
This is the second axis, and it affects cost and time far more than the label “type” does.
- Single tooth. One implant and one crown replace one missing tooth, without involving the neighbouring teeth. Compare this with a bridge, which relies on them: our implants versus bridges checklist walks through the trade-offs.
- Several missing teeth. You do not always need one implant per tooth. A bridge supported by implants can replace a short row of teeth with fewer posts.
- Full arch. A whole upper or lower set of teeth is supported by several implants, either as a fixed bridge or an implant-retained denture. If you are weighing this against removable options, read implants versus dentures in Dubai.
When a whole mouth needs rebuilding, with worn, missing or failing teeth together, planning happens as one programme. That is the idea behind full mouth rehabilitation.
What decides which type is right for you
DHA clinical guidelines, effective 1 March 2026, say that the success of implant therapy depends on the surgeon’s competencies, the patient’s general health, medications that affect bone integration, and the health of the tissues. Translated into the questions your dentist will ask:
- Bone volume and quality. A 3D scan shows whether there is enough height and width for an endosteal implant, or whether grafting or an alternative design should be discussed.
- Gum health. Active gum disease must be treated first. If that sounds familiar, see our gum disease treatment and what to expect from periodontal root planing.
- General health and medicines. Tell your dentist about every condition and medicine, including supplements. Some affect how bone heals, and that is a judgement for your doctor, not something to guess from a website.
- Number and position of missing teeth. This shapes whether you need one implant, a bridge on implants or a full-arch plan.
- Spacing. The same guidelines state that implants must be placed at least 1.5 mm from adjacent teeth and at least 3 mm from adjacent implants. This is why precise planning matters, and why crowded sites sometimes need a different design.
- Your goals. Fixed teeth, removable but stable teeth, speed, and how much treatment you are willing to undergo all influence the plan.
What the process looks like
The exact steps depend on your case, but the usual sequence is:
- Consultation, examination and a 3D scan.
- Treatment of any decay, infection or gum disease. Decayed teeth that can be saved may need root canal treatment instead of removal.
- Any bone or gum preparation that your scan shows is needed.
- Implant placement, followed by a healing period while the bone integrates.
- The final crown, bridge or denture is fitted and checked.
- Regular hygiene visits and check-ups, because implants need clean surrounding gums to last.
Your dentist will tell you the timing for your own case. Treat any clinic that promises identical timelines for everyone with caution.
How to compare implant quotes in Dubai
Prices vary because the plans behind them differ. Before comparing two numbers, check that both quotes state:
- the implant type and the number of implants;
- whether the crown, abutment and scan are included;
- whether bone grafting or gum treatment is included or extra;
- who places the implant and where the work is done;
- follow-up visits and what happens if something needs adjusting.
You can also ask which DHA-licensed clinician is responsible for your treatment, and check the clinic’s licence on the authority’s official channels.
Our perspective
Patients usually arrive asking for a type: “I want mini implants” or “I want All-on-4”. We start one step earlier. The right implant is the one your bone, gums and general health can support, and that is only clear after a scan and a proper consultation.
We see implants as one part of a wider plan. Our approach is to bring dentistry, gum care and restorative work together under one roof, so the infection is treated, the gums are healthy and the new teeth are designed to look natural before anything is placed. Doctor-led consultations and modern imaging are how we aim to make that calm and predictable.
If you have been told you lack bone, ask about all the routes: preparing the site, a different design, or a staged plan. A good plan explains why a type fits you, and shows you what it looks like in your own scan.

Questions people ask
What are the two types of dental implants?
The two main types are endosteal and subperiosteal. Endosteal implants go into the jawbone and are the most widely used. Subperiosteal implants sit under the gum on or above the bone and are generally reserved for people without enough bone height for an endosteal implant.
Are screwless dental implants a different type?
Not in the way endosteal and subperiosteal are. The term is mostly used for how the tooth is attached to the post, not for a different way of anchoring in bone. Ask your dentist to explain exactly what a clinic means by it and what the final tooth is attached with.
How many implants do I need to replace four teeth?
It depends on where the teeth are, your bone and the bite forces involved. Four missing teeth in a row do not always need four implants, because an implant-supported bridge can span the gap with fewer posts. Your dentist will decide after a scan.
What is the 3/2 rule for implant placement?
The rule is about spacing, and the version in Dubai’s guidelines gives the minimum distances: at least 1.5 mm from adjacent teeth and at least 3 mm from adjacent implants. Your dentist plans the positions on your scan to respect these distances.
Can I have an implant if I have lost bone?
Often yes, but the route changes. Options include preparing the site, or a custom subperiosteal design in selected cases. Research on custom designs is promising but limited, so ask your dentist why a specific option is proposed for you.
