Genuinely painless anesthesia, and saving natural teeth to the very end

What i-ject changes

• Automatic pressure control in 0.1 ml/sec increments — the biggest cause of injection pain is the pressure of anesthetic entering too quickly. i-ject controls the delivery rate in 0.1 ml/sec increments so tissue pressure stays constant; many patients do not even notice the moment the injection begins.
• 32G ultra-fine needles — we never economise on needles — a blunter needle tears tissue and hurts more, and finer needles cost more. We use only premium 32G needles, because the price difference of a single needle translates directly into the patient’s experience of pain.
• Ampoule warmer — the sharp, alien sensation of cold anesthetic disappears when the solution is warmed close to body temperature (37°C) before injection.
• pH and temperature optimised in advance — the acidity and temperature of the anesthetic affect tissue irritation, so we optimise these conditions before injection to reduce chemical irritation as well.
• Skilled in a wide range of block techniques — inferior alveolar, nasopalatine, posterior superior alveolar, mental and infraorbital nerve blocks are selected according to the situation.

• Immediate effect — no waiting — ordinary infiltration anesthesia takes 5–10 minutes to pass through bone and reach the nerve. Because periodontal ligament anesthesia is delivered directly through the ligament space around the tooth, the effect is almost immediate. There is no tense waiting time.
• Only the tooth is numbed — no numb lip, cheek or tongue — conventional block anesthesia numbs a wide area of nerve, leaving the lip, cheek and tongue numb for hours. Periodontal ligament anesthesia precisely numbs only the area around the tooth being treated, so you can eat straight after treatment.
• No pain — synergy with i-ject — the solution is delivered into the ligament space at a constant 0.1 ml/sec under i-ject computer control. With topical anesthesia followed by i-ject periodontal ligament anesthesia, many patients never feel the sensation of being injected at all.

• Lower anterior teeth — D1 cortical bone and bilateral nerve supply — the bone of the lower front teeth is extremely hard D1 cortical bone, which anesthetic can barely penetrate. In addition, the inferior alveolar nerve supplies both sides of this region, so a one-sided block leaves the opposite nerve unaffected. Solution: inject directly inside the bone with QuickSleeper intraosseous anesthesia.
• Lower molars — thick cortical bone — the outer cortical bone of the lower molars is very thick, so infiltration alone cannot get through it, and even an inferior alveolar nerve block is sometimes incomplete. Solution: combine block, periodontal ligament and intraosseous anesthesia.
• Severely inflamed sites — acidic pH reduces the effect — badly inflamed tissue turns acidic and the ionisation balance of the anesthetic breaks down, which is why waiting longer does not help. Solution: QuickSleeper intraosseous anesthesia bypasses this environment and acts directly near the nerve.
• Anesthesia-resistant constitutions — differences in metabolism or nerve distribution — some patients metabolise anesthetic quickly or have a different nerve distribution, so ordinary methods do not work well. Our principle: if anesthesia is insufficient we never ask you to endure it. We secure complete anesthesia with QuickSleeper before starting treatment.

• How it differs from conventional endodontics — the conventional approach scrapes the canal with files and irrigates with sodium hypochlorite (NaOCl). But files cannot reach deep into the fine accessory canals and dentinal tubules that branch like tree roots, so bacteria remain and the infection recurs. With Plazen®, reactive oxygen species penetrate every corner like a mist and sterilise areas a file can never touch.
• Two seconds per canal — treatment time falls dramatically — conventional irrigation takes about 15 minutes per visit; Plazen® irradiation takes just two seconds per canal. Pulp removal, filing, plasma sterilisation and canal filling are completed in around 30 minutes, reducing the burden of repeated visits.
• Markedly less post-operative pain — because bacteria and organic matter in the canal are almost completely removed, the “debris” that could escape beyond the apex is minimised. Patients who used to ache for days after root canal treatment tell us it “hurt less than expected”.
• The same national health insurance fee — under Health Insurance Review and Assessment Service rules, root canal treatment is covered by national insurance, and although this is expensive specialist equipment we provide Plazen® at no additional charge, at exactly the same insured fee. Better treatment for the same cost.
• No NaOCl — no bleach smell, no risk — there is none of the distinctive bleach odour of conventional irrigant, and no risk of bleached clothing from splashes.
• More comfortable with painless anesthesia and an electric motor — the i-ject and QuickSleeper units minimise injection pain, and the electric-motor handpiece reduces damage to tooth structure during canal shaping through precise speed control.

• Why retreatment is difficult — the canal is already filled, so the existing material (gutta-percha and so on) must be removed first. Bacteria hidden deep inside complex, twisting canals are hard to eliminate completely, and the resistant strain E. faecalis in particular is difficult to remove with ordinary irrigants.
• Plazen® sterilises even the finest canals — applying Plazen® plasma after removing the old filling eliminates residual bacteria hiding in accessory canals and isthmuses that files could never reach. Reactive oxygen species are effective even against resistant strains such as E. faecalis.
• Minimal mechanical enlargement — protecting the tooth walls — over-widening the canal during retreatment thins the walls and raises the risk of fracture. Because Plazen® takes care of sterilisation, filing can be limited to securing minimal space, so tooth structure is better preserved.
• Comfortable retreatment with painless anesthesia and an electric motor — retreatment can take longer because of the extra step of removing old material. The i-ject and QuickSleeper units minimise anesthetic pain, and precise electric-motor speed control reduces unnecessary damage while old filling is removed.

• Plazen® minimises loss of root length — textbooks specify 3 mm resection as the rule, but when Plazen® plasma sterilises every corner of the root tip, only a minimal amount needs to be cut — or bacteria can be killed with no resection at all — so the tooth’s support is preserved intact.
• Maruchi MTA — premium biocompatible sealing material — after resecting the root tip we seal it with Maruchi MTA, a premium-grade Mineral Trioxide Aggregate with excellent biocompatibility and sealing ability, which lowers the chance of recurrence.
• Teeth with posts — sterilised directly through the post — even when a metal post is set deep inside a crown and retreatment from above is difficult, irradiating the post directly with Plazen® plasma sterilises bacteria below the post and in the surrounding dentinal tubules. It blocks periapical infection without removing the crown or post.
• Electric-motor high-speed bur — precise, rapid surgery — a high-speed bur on an electric motor cuts bone and tooth at a constant speed without judder. Unlike an air turbine with fluctuating speed, the surgical site is smoother and heals faster. The i-ject and QuickSleeper units also minimise anesthetic pain before surgery.

• Lower molars — when an apicoectomy cannot reach — the root tips of lower molars lie close to nerves and vessels, which makes surgical access difficult. Because intentional replantation takes the tooth out and works on it outside the mouth, treatment is possible regardless of anatomical position.
• Plazen® irradiation in the mouth → extraction → precise treatment outside — before extraction we irradiate with Plazen® plasma in the mouth to sterilise the canal and root tip as far as possible. The tooth is then extracted and the root tip resected and sealed with Maruchi MTA under direct vision outside the mouth. With no limits on visibility or access, treatment can be more complete than intraoral surgery.
• Replanted in the shortest possible time — the longer the tooth is outside the mouth, the more the periodontal ligament cells are damaged. Rapid team co-ordination keeps the extraoral time to a minimum and improves the prognosis.
• The last option before an implant — when intentional replantation succeeds, the natural tooth can serve for decades more. Even if it fails an implant remains as a second choice, but we try this method first.

Features and range of application

• Anterior teeth — possible even when only the root remains — even when a front tooth is so badly fractured that almost no crown structure is left, we first consider saving it with our specialised technique and an endocrown approach rather than extracting it.
• Applicable to both anterior and posterior teeth — it is mainly used on front teeth, but in our clinical experience posterior teeth are often possible too. It may be unsuitable where there is bruxism, deep bite, malocclusion or clenching, so a consultation is needed; even then it is sometimes possible if you agree to wear a night guard.
• We save teeth that other clinics wanted to extract — most clinics do not perform endocrowns, often because they cannot or because it is difficult, and as a result patients are advised to “extract and place an implant”. Because this treatment is available here, we can offer one more option to people who were told elsewhere to have the tooth out.

Indications

• Cervical wear composite ★ most common — non-carious cervical lesions (NCCL) at the neck of the tooth are restored with composite, resolving sensitivity and improving appearance at the same time.
• Occlusal wear composite — biting surfaces worn by bruxism, clenching or abrasive foods are rebuilt with composite. Restoring height and shape also reduces the load on the jaw joint.
• Pit and fissure, proximal, simple and complex composites — treatment is not limited to cervical and occlusal wear: occlusal grooves, between teeth, and simple or complex restorations according to the extent of decay are all possible. The strong bond keeps them in place for a long time.

The ICON process (completed the same day)

• Step 1. Q-ray precise diagnosis — fluorescent light is used to check the extent of demineralisation and the surface condition. If the surface is already broken down, we tell you honestly that an alternative to ICON is needed.
• Step 2. HCl surface pre-treatment (etching) — a 15% gel opens the enamel surface to create a path for the resin to infiltrate the pores inside.
• Step 3. Ethanol drying — moisture is removed completely so the resin can penetrate deeply and evenly.
• Step 4. ICON resin infiltration and light curing — genuine DMG Icon resin is applied and cured with a light unit. You can eat immediately the same day.

Our TMJ treatment programme

• Precise diagnosis — CT, history, auscultation, inspection — CT imaging together with history-taking, auscultation and inspection maps the anatomical structure precisely and identifies the root cause of the problem.
• Conservative medication — for early or acute pain we first use conservative medication that supports the body’s natural recovery rather than unnecessary intervention.
• PHL combined physiotherapy plus spray-and-stretch — combined low-level laser (LLLT), infrared and electrical stimulation energy relieves inflammation and pain quickly, with cooling-spray stretch therapy alongside it to relax the muscles.
• Custom splint — used for joint noise, pain, bruxism, clenching and degenerative arthritis. It guides the joint into its most stable position and fundamentally releases muscle tension.
• ARS (anterior repositioning splint) — for demanding cases of non-reducing disc displacement in which the disc has slipped forward and the mouth will not open. Made in house to reduce the cost to the patient.
• Snoring and sleep apnoea splint — a custom appliance secures airway space without surgery, helping to relieve snoring and sleep apnoea.
• Jaw-closing muscle botox — we do not do one-third treatments — botox to the masseter alone is a one-third treatment. Precise injection into all three jaw-closing muscles (temporalis, medial pterygoid, masseter) fundamentally resolves overload on the joint.
• Lateral pterygoid botox — recurrent dislocation — recurrent jaw dislocation is treated with lateral pterygoid botox, available at only a small number of clinics in Korea, weakening the pull of the muscle that draws the condyle too far forward.
• Precision injection therapy — intra-articular injections (steroid, hyaluronic acid), prolotherapy (ligament strengthening) and trigger point injection (TPI) relieve inflammation and strengthen weakened tissue.
• Advanced manual and specialist procedures — including joint lavage — jaw dislocation is resolved immediately by manual reduction (closed reduction). Joint lavage washes out inflammatory mediators, and demanding specialist procedures such as release of joint ankylosis and auriculotemporal nerve anesthesia are also performed.

• Masseter — square jaw and bruxism — the best-known site. Reducing the volume of a developed masseter improves a square jaw line and relieves jaw pain from bruxism and clenching. On its own, however, the effect is limited; the synergy is much greater when combined with the temporalis and medial pterygoid.
• Temporalis — temple pain and headache — this muscle becomes over-tense along with the masseter during bruxism and clenching, and its tension is often the direct cause of temple headache and migraine. It must be treated together with the masseter to address the whole closing pattern.
• Medial pterygoid — deep jaw pain — located deep on the inner side of the lower jaw, it is rarely treated in dermatology clinics or general dental practices. Patients who still have pain inside the jaw or in front of the ear after masseter and temporalis botox often have the medial pterygoid as the cause.
