MegaGen AnyRidge Dental Implants in Ukraine

AnyRidge is a line of dental implants from the South Korean company MegaGen. It is recognisable by its thread geometry: the threads are deep, thin and sharp (the manufacturer calls them Knife-thread), and the core of the implant is deliberately narrow. The diameter in each size designation is the outer thread diameter; the core diameter stays the same across the line.

The practical point of this design is a larger bone contact area. A deep thread reaches further and grips a larger volume of cancellous tissue than a shallow thread in a site of the same diameter. That is why AnyRidge comes up most often in the context of porous bone, where conventional thread designs give only weak primary stability.

The indications are broadly the same as for any implant treatment: a single missing tooth, a gap between teeth or at the end of the arch, or complete tooth loss. AnyRidge is considered in particular when the bone is porous (types D3 and D4), when a tooth has been missing for a long time and the ridge has had time to remodel, and when the implant is planned to go straight into the socket of an extracted tooth. It does not pay to wait too long: once a tooth is lost, the bone at that site gradually shrinks, the neighbouring teeth tilt and the opposing tooth over-erupts, so eventually the implant has to be combined with bone grafting or orthodontic preparation.

Implants are not for everyone. They are not planned before the jaws have stopped growing, in uncontrolled diabetes, during chemotherapy or radiotherapy to the head and neck, in patients on intravenous bisphosphonates or denosumab injections for cancer, or with untreated periodontitis and poor oral hygiene. Smoking, bruxism and pregnancy do not rule implants out, but they are a reason to change the timing or the protocol.

MediUkraine is a treatment search and coordination service, not a clinic. We match you with a clinic and a suitably specialised doctor, arrange the dates and support you throughout, including if you are travelling from abroad. The choice of system, implant size and protocol rests with the doctor after an in-person examination and review of the scan.

Knife-thread is a thread that is deep but thin. On a conventional implant the thread is shallow, so the outer diameter is not much larger than the core; AnyRidge has a deliberately narrow core with the thread extending far outwards. That is why the size designation gives the outer thread diameter rather than the body diameter: implants of different "widths" within the line share the same core, go into sites of similar diameter and differ only in thread depth.

Primary stability is the mechanical hold of the implant in the bone immediately after placement, before any integration. It is created by friction and compression between the thread and the walls of the site. A deep, sharp thread reaches further into the bone and grips a larger volume of cancellous bone, so the implant can hold even where the cortical plate is thin and the bone inside is soft.

Bone density is graded from D1 to D4: D1 is the dense cortical bone of the front of the lower jaw, D4 the loose cancellous tissue of the posterior upper jaw. D3 and D4 cause the most problems: the site turns out "hollow", the implant spins, and immediate loading is out of the question. In such cases the site is underprepared, that is, made narrower than the implant, so that the bone is compacted around the threads rather than drilled away.

Stability is not judged by eye. Insertion torque is read off the implant motor in newton-centimetres: the reference point for immediate loading is around 35 N·cm and above. The second metric is ISQ, a stability quotient on a scale from 1 to 100, measured by resonance frequency analysis: values of around 70 and above are usually considered sufficient for loading, and below 60 a reason to wait. Both figures go into your record so that they can later be compared with a repeat measurement before the prosthetic stage.

Between mechanical hold and integration there is a gap known as the stability dip. In the first two to four weeks the bone around the threads remodels, the mechanical compression weakens and new bone has not yet formed, so overall stability is at its lowest in this period. Geometry with a large contact area smooths out the dip but does not eliminate it, which is why the doctor decides how much load the implant can take in the first month based on the measurements, not on how the patient feels.

The surface takes care of the biological side. AnyRidge uses Xpeed, a sandblasted and acid-etched surface into which calcium ions are additionally incorporated. The idea is to make the surface more active and to speed up mineral deposition and the attachment of bone cells in the first weeks. This affects the speed of secondary, biological stability, not the mechanical hold on the day of surgery.

The connection to the abutment is conical, with an internal hexagon and platform switching: the edge of the prosthetic part is slightly narrower than the implant platform, which moves the microgap zone inwards, away from the bone edge. Abutment options include stock straight and angled abutments, titanium bases for custom zirconia restorations, and multi-unit abutments for full arches. The abutment is tightened with a torque wrench to the torque set by the manufacturer, usually around 30 N·cm.

The system is chosen to fit the clinical situation, not for its name. AnyRidge makes sense when the bone is porous, when the implant is placed straight into the socket of an extracted tooth and needs to grip its walls, and when the width of the ridge is limited. In dense D1 bone, by contrast, a deep thread works against itself: high insertion torque puts excessive pressure on the cortical layer, which risks impairing the blood supply and causing marginal resorption. In that case the site is drilled wider or a different design is used: MegaGen itself has other lines for this, and the clinics also offer systems from other manufacturers.

Implant geometry does not replace bone volume. If the ridge is narrow or the height below the sinus is small, bone grafting or a sinus lift is needed, which are separate procedures with their own timelines and risks. Likewise, the choice of system does not remove the need to treat periodontitis: an implant cannot decay, but the tissue around it becomes inflamed in the same way as around a natural tooth.

A practical point if you live abroad: MegaGen is distributed in many countries, so the system's prosthetic components are available not only where the operation took place. To make use of this you need the implant passport with the product code and serial number, so keep it together with your discharge summary. The manufacturer's warranty covers the product itself, not the clinical outcome: only a doctor who has examined you can predict the outcome in your case.

Expect swelling for the first two days. On the first day, apply cold through a cloth for 15–20 minutes at a time with breaks, sleep with your head slightly raised and eat soft, cool food. Do not rinse your mouth at all on the day of the operation, and from the next day switch to gentle antiseptic mouth baths without vigorous rinsing, so as not to dislodge the blood clot from the wound.

Swelling peaks on the second or third day and then goes down; a bruise on the cheek sometimes appears later and lasts up to a week. Painkillers are taken as prescribed, and an antibiotic, if prescribed, is taken as a full course. Hot baths, saunas and the gym are best avoided in the first days, and it is best not to fly on the first day.

Stitches are removed on day 7–10 unless dissolvable sutures were used. At the same visit the doctor checks how the gum has healed. This is a soft tissue check, not yet an assessment of the implant itself.

Osseointegration, the bonding of bone to the implant surface, takes on average 2–3 months in the lower jaw and 3–6 months in the upper. If bone grafting or a sinus lift was done at the same time, the period extends to 6–9 months. Before the prosthetic stage, stability is measured again and compared with the figure recorded on the day of the operation.

Next a healing abutment is fitted and the gum is left to take shape around it for another 2–4 weeks; then a digital scan or impression is taken and the crown is made. The result is assessed not on the day the crown is fitted but 2–3 weeks later, once you have got used to chewing on the new tooth and the doctor has checked the bite under real load.

Long-term monitoring relies on X-rays. A follow-up X-ray is taken after the crown is fitted, then a year later and annually after that: normally the bone level at the neck of the implant drops by no more than 1.5 mm in the first year, and by about 0.2 mm a year in subsequent years. Visits to the hygienist every six months are part of the plan, not an optional extra: most late problems start with plaque and inflammation of the mucosa around the crown.
