Implant dentures are pure titanium implants (ie, high-tech bionic artificial tooth roots) that have good tissue compatibility with the human body. They are implanted into the missing tooth site through minimally invasive surgery. After a period of time to achieve osseointegration, the artificial tooth roots are connected Dentures (dentures) to repair missing teeth. It belongs to the advanced technology of today's stomatology and is known as the "third pair of teeth" of human beings.
Implant dentures are an emerging method of dental restoration. It consists of a lower dental implant and an upper artificial denture.

Advantages:
1. Implant dentures have the advantages of good retention, stability, high chewing efficiency, beautiful appearance and comfort, no foreign body sensation in the mouth, and no abrasion of healthy adjacent teeth.
2. Implant dentures can avoid or reduce the abutment preparations required for fixed dentures, their possible adverse consequences, and the psychological burden on patients.
3. Since the implant denture has no base or a small base area, it has good comfort. The dental implant fee standard is mainly determined by three aspects-the local consumption level, the choice of dental implant system, and the condition of the alveolar bone. If the bone mass is not enough, bone grafting is needed, or periodontal treatment is performed in advance, or bone powder is added, or maxillary sinus is lifted. This is generally based on the original charge. It is recommended that you go to the hospital for an examination and let the doctor give further plans and prices.

Common denture materials are as follows:
1. All-ceramic material: biocompatibility, no irritation to the gums, no allergic reactions. It is metal-free repair and has no effect on the results of nuclear magnetic inspection. It's very good in terms of aesthetics and comfort. This is the most ideal material. The disadvantage is that some special processing techniques lead to relatively high prices.
2. Resin materials: In the early days, resin materials were relatively poor, and now many imported or processed with special technology are not inferior to other materials. The advantage of resin materials is that they are cheaper. The disadvantage is that it is easy to crack and the service life is not long. Generally, it is 3-5 years. In the production, the thickness of the base is intentionally increased, resulting in poor customer adaptability.
3. Precious metal alloy: It has excellent corrosion resistance, oxidation resistance, closeness, and good biocompatibility. It is an ideal metal full crown repair material with relatively high price.
4. Titanium alloy: It contains a small amount of titanium and is still a nickel-based alloy. High strength, corrosion resistance and oxidation resistance meet the basic clinical requirements.
5. Nickel-chromium alloy: It is an alloy commonly used in China at present, with good strength and gold-ceramic bonding force, and stable long-term use effect. The disadvantage is that due to the active chemical properties of metals, long-term use in the mouth will cause the release of metal components, which will cause black lines in the gums. Therefore, it will affect the aesthetic effect of anterior teeth restoration. In addition, some people are allergic to metallic nickel, so they should be used with caution to those who are allergic to known nickel. The price is also cheap.
6. Cobalt-chromium alloy: It has strong metal stability and high corrosion resistance. Under normal circumstances, there will be no black gums or bleeding gums. It is confirmed by some people that this type of porcelain teeth has poor biocompatibility, which may easily cause allergies and cause inflammation of the skin and mucous membranes. The specific use of porcelain teeth should be determined after consultation with a regular hospital attending doctor.

There are two types of movable dentures: partial movable dentures and full dentures.

There are five types of movable dentures, which are resin materials, nickel-chromium alloy materials, cobalt-chromium alloy materials, titanium alloy materials, and pure titanium materials.

kind:
Locally movable denture
Oral restorations are generally aimed at too many missing teeth, but there are still original teeth remaining. Local movable dentures are divided into three types: traditional metal hook movable dentures, precision double crown dentures and invisible dentures.

2. Full denture
Full dentures are mainly used for dental restorations for patients without teeth or excessive tooth loss. There are many types of full dentures, and the performance, life and price of full dentures with different materials are very different.

Both have advantages and disadvantages:
First, let's talk about fixed dentures: advantages-good retention effect, good support effect, good stabilization effect, high chewing efficiency, patients feel comfortable, no obvious foreign body sensation, easy to adapt, do not affect pronunciation, beautiful, eyes close to natural teeth, no need to pick Wear, easy to use.
Disadvantages-narrow range of adaptation, relatively large amount of tooth tissue that is cut, difficult to adjust and repair, difficult to repair after cementing, and difficult to remove for cleaning.
Then there are movable dentures: advantages-a wide range of applications, less tooth tissue removal, self-extraction, easy scrubbing and cleaning to maintain good oral hygiene, simple production methods, low cost, easy repair and addition The supporting organization can get proper rest, and Kito can fill the defect area to restore proper shape. Disadvantages – The denture is large and has many parts. Patients often feel foreign bodies when they are first worn, sometimes affecting pronunciation and causing nausea. Their stability and chewing function are not as good as fixed dentures. If the design of the denture is not reasonable, the quality is poor or the patient is not easy Maintaining oral hygiene and other conditions may also bring adverse consequences such as abutment injury, mucosal ulcers, plaque formation and calculus accumulation, dental caries and periodontitis, accelerated alveolar ridge absorption, and temporomandibular joint disease.
