POSSELT · IMPLANT CARE

Full-arch implants and revision in Asan.
We start by planning the final teeth.

Dr. Taehoon Lee at Posselt Dental Clinic uses CT and intraoral scans to assess whether remaining teeth and existing implants can be retained, alongside the jawbone, final restoration and bite, and explains the treatment plan.

Implants replace tooth roots; the restoration above them replaces the teeth. Dr. Lee considers starting designs of 18 implants supporting 28 teeth or 14 supporting 24, with three segments in each arch. The final number and structure depend on the individual assessment.

These are actual patient treatment records. Camera angles and lighting differ. Treatment methods, duration and results vary by person. Implants may involve risks including bleeding, infection, nerve injury and implant failure.

Restoring support on both sides with dental implants

Restoring support on both sides with dental implants

Decay and missing back teeth had led to loss of posterior occlusal support. Implant-supported restorations were used to restore contact between the upper and lower back teeth on both sides.

Restoring right back teeth with implants and sinus grafting

Restoring right back teeth with implants and sinus grafting

After tooth loss, opposing teeth had overerupted and neighbouring teeth had tilted mesially, altering the bite. Treatment included extraction, upper-right bone grafting through a lateral approach, and staged implant-supported restoration of the upper and lower right posterior teeth.

Implants with bone grafting

Posselt dental clinic

Building a firmer foundation: bone grafting for implants

Implants need supporting jawbone. Gum disease or long-term denture use can lead to bone loss, which may make implant placement difficult after assessment. At Posselt Dental Clinic, we use different bone grafting methods to rebuild lost bone and support stable, long-term implant use.

  • 01

    When gum disease or other conditions
    have reduced the amount
    of supporting jawbone

  • 02

    When damage to the alveolar bone
    and periodontal ligament has caused
    loose or missing teeth

  • 03

    When a sinus lift
    is needed

  • Discuss options for insufficient jawbone

    When bone grafting
    may be needed

Aesthetic restorations & no-prep veneers

specialized treatment 02

Aesthetic restorations &
no-prep veneers

We assess tooth color, shape and alignment along with gum health and your bite. Whether no-prep veneers are suitable and how much tooth preparation is needed are decided individually; damaged teeth and existing restorations are assessed separately to determine whether a crown or bridge is appropriate.

SEDATION CARE

Feeling anxious about dental treatment?
Discover conscious sedation.

Sedation uses medication to ease anxiety, as with sedation for endoscopy.
We assess your health and treatment needs, and monitor your responses and breathing throughout.

Before treatment · Review your health and medications

During treatment · Observe oxygen saturation and breathing

After treatment · Check recovery and arrange an accompanied journey home

Sedation effects and recovery time vary by person. Respiratory depression, low oxygen levels, nausea and vomiting can occur, so assessment and monitoring are necessary.

Our newly introduced syringe pump · actual equipment at Posselt Dental Clinic
Preparation & frequently asked questions

Is this the same as sedation for endoscopy?

Both use medication to reduce anxiety and tension. It is not a fixed method that puts everyone to the same depth of sleep. We aim for conscious sedation, adjusting it to the patient's condition and responses, while also using local anesthesia to manage pain at the treatment site.

Which medicines are used?

We select suitable sedatives, such as midazolam or propofol, according to the patient. Injectable pain relief and medicines to reduce nausea or vomiting may be added when needed. The choice and dose depend on health, medications and treatment.

What should I prepare before visiting?

Tell us about your medications and medical conditions. Receive individual fasting and medication instructions when booking. Do not stop medicines on your own, and arrange for a responsible adult to accompany you home.

What happens after treatment?

After we check your recovery, you leave with an accompanying adult. Avoid driving, alcohol and operating machinery that day, and rest as instructed. Respiratory depression, low oxygen levels, nausea and vomiting are possible, making assessment and monitoring necessary.

    For facial botulinum toxin and vertical neck bands, suitability is decided after assessment.

How botulinum toxin works

Reducing signals sent to the muscle

Reducing signals sent to the muscle
  1. Motor nerve ending · Acetylcholine · ACh
  2. Release protein · SNAP-25 · Type A toxin · inhibits release
  3. Reduced muscle activation

Botulinum toxin type A inhibits transmitter release from nerve endings, reducing muscle activity.

This is a simplified mechanism. HiTox approval limits and off-label use in other facial or neck areas are explained separately.
