What Are the Different Types of Cosmetic Dental Implants?

Dental implants are also known as dental implants and also called artificial tooth roots. It is implanted into the maxillary bone of human body with missing teeth by surgical operation. After the surgical wound is healed, a device for repairing artificial teeth is installed on the upper part.

(1) Body: both

Ceramic materials: including bio-inert ceramics, bio-active ceramics, and bio-degradable ceramics. With high mechanical strength, corrosion resistance, no irritation and toxicity, and histocompatibility. It is also currently in clinical use.

Carbon materials: including glassy carbon, low temperature isotropic carbon, etc. The advantage is that it has higher stability in the living body and has no biodegradation effect.

Metal and alloy materials: including gold, 316L stainless steel (iron-chromium-nickel alloy), cast cobalt-chromium alloy, titanium and alloys. Its advantages are high strength and good rigidity, but its biomechanical adaptability and tissue and bone adaptability are poor.

Polymer materials: including acrylates, polytetrafluoroethylene, etc. Some polymer materials have a similar chemical structure to natural polymers in the structure of the human body, but are easily degraded and stimulated by the organism.

Composite materials: the combination of the above two or more materials, such as spray-painted ceramics on metal surfaces. Human teeth are often complexes containing complex components of organic and inorganic matter. Due to the limitation of a single structure, the above single materials often cannot meet the requirements of living organisms, so the applications of composite materials have become increasingly widespread. Such as carbon-coated metal composite materials, porous coating alumina materials, etc., complement each other to improve performance.

Osseointegrated implant

Intra-bone implants are common: leaf-shaped implants, cylindrical implants, spiral implants, anchor-shaped implants, mandibular implants and ascending-branch implants.

In the late 1960s, a two-stage titanium implant series created by Professor Branemark of Sweden first confirmed and proposed the theory of osseointegration. The concept of osseointegrated implants proposed by Branemark refers to a strong, durable and direct bond between the living bone tissue of the human body and the titanium implant, that is, between the surface of the implant bearing the force and the active bone tissue There is a direct connection in structure and function. There is no connective tissue between the implant and bone tissue, and there is no interval between them.

Pure titanium implants are often referred to as "osteointegrated titanium implants" because of their good physical and chemical properties and good biocompatibility with the human body.

Two-stage implant

That is, the implant abutment and the retainer are divided into two sections instead of a whole type of implant. During the operation, the abutment combined with the bone tissue and the abutment combined with the gingival tissue were completed by two surgical implantations before and after, and the two parts of the abutment and the retainer were inserted through the implant center screw. It is connected as a whole. In the first operation, the retainer is implanted into the bone tissue and the wound is sutured. After 4 to 6 months, the implant retainer will be ossified with the bone tissue under a completely unloaded rest state, and then the second operation will be performed. That is, the gingival tissue is cut, and the abutment is connected to the abutment through the center screw of the implant. After disassembly, the mold can be taken and the final restoration can be completed.

The advantages of two-stage implants are that the implants have good osseointegration, are not easy to be infected, and the denture has various repair methods. The upper structure can be selected in a variety of ways. The long-term effect is good and the success rate is high. The disadvantage is that it takes two surgeries to complete.

One-piece implant

That is, the implant abutment (the part bonded to the gum) and the retainer (the part bonded to the bone tissue, that is, the artificial tooth root)

A type of implant that is a connected whole. During the operation, the retainer combined with the bone tissue and the abutment part combined with the gingival tissue are implanted as a whole. When the implant retainer is implanted into the bone tissue, the abutment directly penetrates the gums and is exposed to the mouth. After disassembling, you can wear temporary dentures. After the implant is stable for 4-6 weeks, take the mold and complete the final restoration.

The advantage of a one-piece implant is that it can be done in one operation. However, because the abutment is directly exposed to the oral cavity, the abutment is susceptible to external forces and generates movement. It is difficult to ensure that the implant retainer can be combined with bone tissue in a completely unloaded resting state within a certain period of time. The periodontal descending directly affects the bone tissue and is not conducive to the healing of the implant-bone tissue interface and the gingival tissue interface, so its effect is not as high as the success rate of the two-stage implant.

Bioceramic implant

Bioceramic implants are mostly made of single crystal alumina or polycrystalline alumina. Monocrystalline alumina implants are transparent, also known as bioglass, and have good biocompatibility. The genus immediately penetrates the gingival implant, but does not advocate immediate load. This implant is only suitable for single tooth replacement or as the distal abutment of partial fixed dentures in the posterior region of the mandible. It is generally not suitable for the restoration of partial maxillary dentures or full toothless implant dentures. ^[1]
