Immediate implantation and short implants

Q: Can every extraction be followed by immediate implantation?

No. Socket, inflammation, soft tissue, primary stability, and the later restorative concept must be suitable.

Q: Is immediate implantation the same as fixed teeth in one day?

No. Timing of implantation, loading, and definitive restoration are separate decisions.

Q: When are short implants an option?

Short implants can, in selected situations, be an option to use existing bone. Whether and to what extent bone augmentation can be avoided depends on findings and the planned restoration. Studies use differing length definitions (e.g. <8 mm for overdentures versus other cut-offs elsewhere); the practice KUS orientation ≤6 mm is not a study definition.

Q: Are short implants less safe?

Suitability does not depend on length alone. Region, bone, implant geometry, load, and prosthetics determine individual risk. Systematic reviews exist for selected indications.

Q: Can a short implant always replace bone grafting?

No. It can avoid grafting in certain situations; with unfavourable position, lacking stability, or aesthetic demands, augmentation may still be required.

Q: Who assesses complex bone situations?

At MEDIKUSS assessment is under the leadership of Hans Krehn, specialist in oral and maxillofacial surgery, physician and dentist.

Implantology as surgical–prosthetic overall planning

An implant is not planned in isolation. Bone, mucosa, neighbours, bite, cleanability, and the later crown or bridge jointly determine position and approach. As specialist in oral and maxillofacial surgery as well as physician and dentist, Hans Krehn can also assess complex bone and soft-tissue situations across disciplines. That implies no guarantee that implantation is possible in every situation; medical suitability and a justifiable benefit–risk ratio remain decisive.

What does immediate implantation mean?

An implant is placed into the socket immediately after tooth removal. It differs from immediate loading and from immediate provisional or definitive restoration. These steps can be combined but each has its own prerequisites.

When is immediate implantation suitable?

Assessed are among others reason for removal, acute infection, socket integrity, soft tissue, bone supply, achievable primary stability, aesthetic zone, and planned prosthetics. If risk is unfavourable, delayed implantation may be biologically safer or more predictable.

What are short implants?

Length is a feature of the planned restoration; different lengths can be available within one implant line. Depending on scientific definition, short implants are implants with reduced length. In selected situations they can use existing bone. Whether and to what extent grafting can be avoided depends on findings and the restoration; studies use differing length definitions (e.g. <8 mm versus other cut-offs). The practice KUS orientation ≤6 mm is not a study definition. Results for one length cannot be transferred to shorter variants. Length alone does not decide success; diameter, surface, position, bone quality, and prosthetic load belong to overall assessment. Implantation remains a surgical procedure without a promise of “always without grafting”, “risk-free”, or “painless”.

Short implant or bone graft?

Both strategies have different options and limits. A short implant can reduce surgical extent, treatment time, and morbidity. Grafting may still be needed if position, stability, aesthetics, or cleanability are otherwise insufficient. The decision follows findings, bone supply, and the prosthetic goal — not a blanket imaging requirement.

The KIS principle (Keep it simple)

KIS – keep it simple – means for MEDIKUSS: safely to the goal with as little effort as possible and as much treatment as needed. Immediate implantation and short implants are therefore not blanket promises, but tools used only when they are medically and prosthetically sensible versus more extensive alternatives. KIS describes the planning; KUS – short and simple – stands for short implants themselves. Immediate implantation is not the same as immediate loading or an immediate definitive restoration.

Practice course at MEDIKUSS in Hamburg

Implantation and the restoration are planned together. A possible course with submerged healing is shown on the surgery page: examination according to findings, implantation including healing, uncovering, placing the restoration typically one week after uncovering, and follow-up. About four months in the upper jaw or three months in the lower jaw are planning examples, not a fixed promise. With bone grafting, immediate implantation, or another healing concept the course may differ.

If the procedure worries you

Mention your concerns when you book. In the conversation you can clarify how treatment proceeds, which pauses are possible, and which form of anaesthesia may be appropriate. Whether bone grafting is needed or a less extensive restoration is possible can only be judged after examination. Marked dental anxiety is a care question in its own right; existing information on sedation and anaesthesia and the Hamburg contact route are on the treatment and contact pages.

Additional explanation on KUS

An additional explanation of implant length and questions for the treatment conversation is on KUS. The operator relationship does not turn that into editorial independence; the implantology account remains on MEDIKUSS.

Risks and alternatives

Possible risks include failed osseointegration, infection, bone or soft-tissue loss, injury to neighbours, aesthetic limits, and technical or prosthetic complications. Alternatives can include tooth preservation, bridge, removable denture, delayed implantation, standard implant with augmentation, or forgoing implantation.
