ST Internal Fixture System

1. Product Summary
This product is a dental implant, which is made of pure titanium, and is implanted into a mandible (the lower jaw bone), or a maxillary jaw bone (the upper bone) as a root of the tooth through the surgical operation by the dentist to restore a chewing function of partially or fully edentulous patients. There are various sizes and shapes to implant into the anterior or posterior site for different conditions of dental loss.
2. Indication for Use
Dental medical device, which is implanted in the upper or lower jaw bone to support prosthetic device such as dental prosthesis, to restore a chewing function of partially or fully edentulous patients
3. Instruction for Use & Procedure
(1) Pre-operative planning
For a successful treatment, the following confirmation procedures should be performed carefully to confirm the treatment plan and evaluation, and also the product with medical and dentistry’ point of view.
  • Should check out the patient’s oral status through the clinical, radiography photo, and model analysis.
  • Should ask the patient’s decision in case of various treatment methods, after providing the sufficient explanation of the merit and demerit of each method and treatment schedule.
  • Should check a patient’s medical history to evaluate the status of patient’s health condition. If there is any doubt about a patient’s health condition, the various clinical tests should be performed to determine the absence of abnormal conditions before preparing for the surgery.
  • Should check the sealing condition of the packaging, which is completely sterilized by gamma-irradiation, to ensure that the product is completely sealed and remains the sterilization status.
  • Should not use the product if the package is not completely sealed or that is torn, and also should certainly check the abnormalities such as foreign body, stain, minute dust, and etc. after opening the package.
(2) Applications
The following explains roughly how to use and operate the product. For a detailed procedure, please refer to the catalog of relevant Implant System issued by T-Plus Implant Tech. Co., Ltd.
  • Drill into the alveolar bone in order to place an implant fixture into the planned location with various surgical instruments. At this time, revolutions per minute (RPM) of the drill should be adjusted according to the condition of the bone and the kinds of surgical instruments. Irrigate sufficiently the saline solution onto the area to prevent the necrosis of bone by heat.
  • After making an appropriate hole for a fixture, confirm the kinds of fixture and size described on the label, and take out the transparent plastic container included ampule from the exterior box.
  • Clasp the convex part downwardly directed of transparent plastic container by one hand. Then hold the arrow mark on the label sticker by another hand and take a medical paper off slowly to open the plastic container. After that, take out the sealed ampule.
  • The cap on the ampule is designed as a “Snap-on” type, which can be easily opened by one-hand and one touch. Clasp the ampule by one hand and then push the cap up by the thumb to separate the cap from the ampule at a time.
  • Check whether the fixture is fixed on a Holder (holder type) or a Titanium leveler (leveler type). For holder type, check the Mount is connected with the fixture. For leveler type, check the Mount is not connected with the fixture. In case the fixture is external type and not connected with the Mount, you should connect the Mount to the fixture.
  • Take out carefully the fixture from the ampule by connecting Handpiece Connector to the fixture or Mount.
  • Position the fixture near the drilled site paying attention during movement that the fixture does not separate from Handpiece Connector & does not become contaminated by foreign bodies.
  • A fixture is implanted into the bone to planned depth by turning(15~30rpm) a Handpiece clockwise with 40-45Ncm torque.
  • If the fixture is not completely implanted into the bone due to the hard bone density, separate Handpiece Connector from the fixture, then finish implanting by using a Ratchet Wrench.
    *In the case of using Ratchet Wrench, it may happen to some possibility of surgical failure due to the structure deformation of inside of fixture by excessive torque. Therefore, the torque under 80Ncm is recommended.
  • After implantation of the fixture, finish the operation by connecting Cover Screw to the fixture with torque under 10Ncm by using Hand Driver to protect the inside of fixture from the foreign bodies, and then suture the surgical site.
(3) Post-operative care
  • After surgery, the healing period depends on each patient’s clinical condition (bone quality, bone quantity, initial stability, loading condition, etc.). Therefore the careful attention of patient and clinician's close inspection on the progress are needed.
  • Give advice to the patient for recognizing that excessive pressure such as masticatory force is not applied to the surgical site during the healing period (Osseo-integration period).
  • Give advice to the patient for taking good care of the patient's oral hygiene to avoid side effects.
  • Attach the identification tag containing the Lot number, which is enclosed in the exterior box, on the patient’s chart, x-ray film, etc. to make it possible to trace the product.
  • Before operating the next stage of surgery, the clinician should check the fixture's progress of Osseo-integration by x-ray image or diagnosis such as percussion reaction.
4. Adverse Effects
  • It could result in implantation failure, like bone loss, low initial stability, fixation failure, irritation and nerve damage.
  • Complications such as edema, hematoma, swellings, ruptures, bleeding, infection, soft tissue ulcer and an open suture site may result from inattentive surgical practice or poor patient overall health.
  • Numbness from nerve damage in the facial area is usually a temporary symptom, but some cases are permanent.
