OSSTEM (osstem) Trade Co., Ltd. is a pure Korean enterprise, the headquartered of company set up branch offices in 12 countries, such as South Korea, the United States, Germany, Japan, Singapore and so on. The implantology system was investigated in 1992, since 1998, the system began to export to other countries. It is the world's sixth largest implantology manufacturer, the production of osstem implantology system maintain market share the first place .in Korea for many years.
ITI system was co-founded in the early 1970s by the preservation of dental department of Bonn university and Straumann Institute which possessed privately by Walden in Switzerland. Since 1974, this system has been applied successfully, and accumulated a large amount of clinical documentation. ITI can be the representatives of non-plant-type two-stage implantology system.
ITI implantology system is characterized by the most contribution to the application of system through gum and Morse taper on the implants. System through gum can avoid abutment implantology surgery and prevent bone absorption due to the inevitable gap between their implants and the base station is located above the crest. After 20 years of clinical tests, ITI's Morse taper is proved that it can withstand the cyclical pressures, and prevent loosening of abutment rotation effectively.
1. Individual tooth missing, implanting bed of missing teeth area is normal.
2. The majority of teeth missing, it is respected to repair with the proposed fixed artificial teeth. Implant abutment in order to reduce the burden of both sides of abutments in the gap of missing teeth.
3. Distal missing teeth, alveolar ridge of missing teeth which absorb severely, can’t bear the load of the denture base.
4. full dentition missing, it is possible to carry out the overlay full dentition or full dentition fixed implant restoration.
5. Jaw defects can be repaired by implanting completion of reconstruction and morphological recovery.
6. Responders who can’t be used to wear a larger base of removable artificial denture for physical or psychological reason or being stimulated by base plate to nausea and vomiting.
1. over 18 years old
2. The bone weight of alveolar bone in the parts of missing teeth is enough (including the height and width).
3. No severe periodontitis, periodontal disease and other serious oral disease.
4. The gap between upper teeth and lower teeth in the bite shall not be less than 0.5 cm.
Germany ANKYOS implantology system, exploring the most advanced international new ideas of implantology "platform conversion” currently. During the process of dental implantology, it retains the maximum number of soft tissues and bones, effectively avoids the re-absorption of alveolar bone which may cause the force reducing of implants and help to keep gingival healthy. Therefore, it especially fit for the patients who want the best cosmetic result of implantology.
The idea of “Platform conversion” is to reduce the implantology platform gradually in order to increase the volume of soft tissues during implantology, and increase the blood supplement of soft tissues around the implantology platform. Director Zhou said that if the implant abutment and the implant have the same diameter, which means the two parts connect directly, it properly cause connective tissue inflammation. However, the "platform conversion" concept is to push artificial teeth connection to the central of the implantology using the component with smaller diameter than the implants’ neck so as to enlarge the distance between surrounding bone and the base station, which may avoid the bone re-absorption after implantology, and provide the tissues around implants greater stability.
The new concept of ‘Platform Conversion" has been carried out successfully for several years.
ANKYOS implantology system, owns the many different original root form implants for choose, such as Xive, Frialit, Ankylos and so on, which create the perfect final "foundation" for the accomplishment of dental implantology. The system has temporary base station to produce provisional crown and abutment which can help shape the formation of a natural gum, and prevent alveolar bone excessive absorption caused by reconstruction by the concept "progressive weight-bearing". The system has proprietary hex connection inside, which can provide good resistance to rotation and greater stability. Therefore, it is the best choice for single tooth and more than two teeth restoration.
Firstly, the individual design, which abandons the traditional denture or set of hooks, makes sufferers feel comfortable and look beautiful, does not affect the normal pronunciation; ANKYOS implantology system can make individual plans for patients, thereafter, there are many advantages like comfortable, beautiful, no traditional denture, no foreign body sensation and no affection on pronunciation etc.
Secondly, the prominent feature of ANKYOS implantology teeth is no injury to the healthy teeth and surrounding tissues. Dentist will do sufficient preoperative oral examination and general health assessment for the patients first, and then make individual planting plans. When ANKYOS implantology tooth are completed, they will rely on their own independent existence of the roots and will not affect the healthy teeth on both sides.
Thirdly, ANKYOS implantology teeth has the features of durable using, its long-term security has been recognized by European and American countries, and in function and appearance it is almost the same as natural teeth
Compared to the traditional dental implantology technology, the Nobel Guide implantology technique in Shenzhen Shuguang Hospital is accurate, safe, and comfortable, it has the following four advantages:
(1) The complete visible design process:
Computer auto-process three-dimensional CT data of patients and determine the exact location of implants simultaneously, meanwhile, it can produce a visual computer templates for guiding surgery by which both doctors and patients can see the precise pre-operative model and implantology effects, therefore, it is convenient for doctors and patients to communicate effectively before surgery;
(2) The implantology process guided by computer makes the implantology teeth more accurate, fast, safe and efficient:
The dental implantology process is controlled by computer and fully in accordance with the computer template. If the doctor has a little deviation during implantology operation of the location and depth of control, the computer will automatically stop the surgical procedure to ensure the accuracy and safety of implantology sites. Because the template is based on the guidance of computer, the operation time is short, and the regular teeth implantology needs an average of just 5-10 minutes for each, and about an hour for a beautiful full dentition.
(3)Minimally invasive treatment, without surgery, less pain:
After the completion of beautiful teeth design plan, the doctors may ask the patients to undergo the surgery. The patients can have a beautiful fixed denture after the minimally invasive surgery with no incision, no flap, and no suture. Moreover, the treatment does not affect the daily lives and works and gives the patients no discomfort.
(4) Promise customers the best treatment and the least cost.
The Nobel Guide technology allows customers to get the best treatment with less money. Patients don’t only avoid a long and painful waiting period, but also greatly reduce the number of referral. In addition, it needs to implant eight nails before, but now only four. As the places of this four implanted nails were analyzed by the computer, they are implanted at the exact place, in which case, they are more stable and economical.
1. Local contraindication
A. Malocclusion: If occlusion is not normal, it is not fit for doing implants. Some may be rectified. (Severe jaw abnormalities, such as malocclusion, biting together, bruxism, chewing and other bad habits patients, it may lead to failure when there is imbalance occlusion or trauma around the implants caused by excessive force.
B. Alveolar bone has pathologic changes: such as residual root, inflammation and so on, after eliminate these pathological changes, the implantology could be taken into consideration. Patients with jaw lesions, osteomyelitis, bone cysts, sinusitis.
C. Jaw after radiotherapy.
D. Progressive periodontitis, mouth infection.
F. Patients with limited mouth opening, heavy psychological mental stress who can not cooperate with the physician, Alcohol drunkards and heavy smokers.
2. Systemic contraindications
Patients with systemic disease and immune dysfunction, such as heart disease, blood disease, diabetes, kidney disease, metabolic bone diseases, mental and neurological disorders who are unable to cooperate with the doctor, and pregnant women.
1. Not to damage the adjacent teeth: porcelain bridge is the traditional repair methods for missing teeth, but it needs to grind the healthy teeth on both sides of the missing teeth small, which is very unfortunate; the teeth implantology means embedding the implants in the alveolar bone of the missing teeth. As the basis for repairing missing teeth, the process neither involves the adjacent teeth, nor damages the adjacent teeth.
2. Steady and stable: implants (artificial teeth) and alveolar bone are connected steady by juncturae ossium, almost the same as people's natural teeth.
3. More scientific principle: natural teeth transmitted the bite force through root to the alveolar bone, while the implantology teeth transmitted the bite force through implanted root (implants) to the alveolar bone. Their bio-mechanics principle is the same, therefore, it can withstand strong force, and the chewing efficiency has greatly improved over the traditional dentures. The traditional porcelain bridge is fixed by retainer paste on natural teeth which is grinding small in both sides of the gap of missing teeth. And the natural teeth are used for support and delivery of chewing pressure, which increase the burden on natural teeth and affect its life span.
4. Smart and comfort: The features that small, no base and card ring structure, no foreign body sensation in the mouth, are conducive to maintaining oral health, sense of comfortable and no presence of artificial dentures.
5. Indication wider: in the conditions of full mouth had no teeth or the back of molars area are all missing, in the past it can only be fitted dentures, but dentures in appearance, comfort, chewing function, self-cleaning capability and other aspects are not satisfactory and the implantology of the artificial teeth can make these patients have been fixed artificial denture.
6. To help prevent the absorption of alveolar bone.
(1) Preoperative routine examination: Check the location of missing teeth, gap size, the width of alveolar bone, alveolar ridge condition, mucosal tissue conditions, then decide to take the implantology surgery or not and the amounts of implants according to their size ,the width and height.
(2) Radiological examination: mainly to know the density and number of alveolar bone and whether they have disease or not.
Dental film can help you know more about the alveolar bone’s density and number, and periodontal tissue, the tooth structure and root tip situation of adjacent teeth.
From the panoramic jaw surface fault slices, you may know alveolar height, nasal floor, maxillary height, the inferior alveolar nerve condition, mental foramen position.
Spiral CT can help you know the alveolar bone height, width accurately, and locate exactly and do the preoperative surgery. The problem of the height of maxillary sinus and inferior alveolar nerve in the posterior areas of the implant area makes spiral CT examination necessary.
(3) The design before implanting: In order to determine the type of repairing, implanting system, the number of implants, position, direction, length, the information, such as the photograph and the models, should be collected before implant operation. And then produce the template for plant operation use, so that the surgery can be done accurately and smoothly.
(4) In order to inhibit the bacteria effectively, inject some antibiotics before surgery.
1. Make the implantology plan after sufficient preoperative oral examination and assessment of general health.
2. Do the first buried implant surgery (artificial teeth) in the condition of local anesthesia, and then sutured mucosa.
3. 1.5-6 months (according to different implantology systems) later after embedded implants, do the second surgery or repair after the implants and bone tissues are seal completely(according to different implantology systems), the patients could wear artificial dentures during this period.
4. The upper structure – produce the artificial dentures.
5. After that, fix the implants with screws or splicing agent and complete the repairing process of implantology.
The whole course of treatment for dental implantology takes about 2-9 months; patients get different implantology systems according to their specific circumstances.
After the minimally invasive implantology surgery
1. patients can have normal diet after the surgery for its invasive is minimal, and wash mouth with gargle, keep oral healthy, food should not be hot.
2. due to physical different and different surgical procedures, small number of patients may have mild local swelling, which will usually gradually subside after 1-3 days.
3. patients shall take oral administrations of antibiotics after surgery to prevent infection.
4. minimally invasive implantology needs no stitch, therefore, patients do not need getting rid of stitches.
After Standard dental implantology surgery
1. Do not brush or wash your mouth within 24 hours after surgery, because too frequent gargling can cause bleeding, but to prevent food debris left in the mouth, patients shall wash mouth with gargle after meal. 2 hours after surgery, moderate consumption of drinking is allowed, and food should not be hot.
2. Routine use antibiotics after surgery. For simple implantology operation (a small number of implants, shorter operation time, and patient recovers soon), patients take oral antibiotics, but for the complex surgery, patients need intravenous antibiotics to prevent infection.
3. Due to physical and surgical procedures different, patients may have different reactions, some have mild or no response, some will lead to local edema and petechiae, usually last for 3-5 days.
4. Generally ,the patients have mild postoperative pain or discomfort, do not need to take painkillers, but if the patients are sensitive and feel more sensitive to pain, acesodyne should be taken after surgery on that day; under normal circumstances, patients no longer have sustained pain perception in 24 hours after surgery.
5. conventionally, stitch in 7-10 days after surgery, stitch on time in order to prevent local infection
