Commonly used in clinical planting system usually consists of three parts


1 implant: is implanted within the bone, the present epidemic is still preform different manufacturers produce implants in shape, length, diameter, surface treatment vary. But, in any case, must be biocompatible implant excellent material such as titanium, bio-ceramics production. So far, titanium is still dental implant material of choice. Titanium is a rare metal, periodic table of 22, an atomic weight of 47.9, a specific gravity of 4.5. Press purity can be divided into four, four hardest but the toughness is less than 1. 4 containing more than 99% of titanium, 100% pure titanium can not be used nor economical. Most of the commercially pure titanium dental implants is that four titanium. Now widely recognized: the titanium metal made of bone implants can produce good osseointegration, its shape may be cylindrical, conical, can be threaded, or not threaded; surface etching, sand blasting or titanium ions surface coating of the rough surface is best because the rough surface can increase the implant and the bone cell contact area.
2 abutments: Is the implant through the soft tissue portion, usually with screws to fasten it to the implant. It can be the use of prefabricated components, or use the personalized production parts. Production base materials used also need excellent biocompatibility, dental Suction Unit such as: titanium, precious metals, zirconium oxide, etc., and processed into an appropriate shape and high surface finish to protect the soft tissue health.
3 Superstructure: refers prosthesis usually has the crowns, bridges, brackets, attachments and other structures. With conventional denture, implant through a standard prefabricated components easier and more accurately through the base station will restorations with implants connected.
Implant - supported dental prosthesis
Including dentition defect used in various types of implant-supported crown, bridge repair, denture repair used in various types of implant-supported fixed and repaired. Implant prosthesis connection with the main use screw-retained and adhesion retention in two ways.
Dental implant adapt to the crowd
Individual missing teeth, missing teeth area planting bed properly.
Most tooth loss, intends to use fixed partial denture, to reduce the gap of missing teeth abutment ends of the burden of the middle need to implant abutments.
Denture teeth, missing teeth absorb severe alveolar ridge can not bear the load of the denture base.
Full mouth tooth loss, viable overlay or full mouth full mouth fixed implant restoration.
Long edentulous hazards
Tooth gap appears: a long missing teeth, close to the teeth will tilt the jaw teeth elongation, dentition integrity destruction, over time, the remaining teeth are gradually sparse open to lose a good close contact, could easily lead occlusal function disorder that.
Masticatory dysfunction: deletion of the remaining teeth, a series of changes, so that the original good occlusal relationship changed due to the remaining teeth between the effective functioning of the area is reduced, chewing function is reduced, missing a first molar full mouth chewing function will be reduced 30% or so.
Alveolar bone atrophy: If missing teeth too long, alveolar bone will be varying degrees of disuse atrophy, and with missing teeth prolonged increase, this will give late denture repair and maintain facial aesthetics coordination enormous difficulties.

Affect pronunciation and appearance: Tooth loss can cause wrinkles increase the appearance of aging, speech is unclear. Eventually becoming restoration, teeth tilt and elongation would prevent jaw normal functional movement, often appear in the joints, pain and limited mouth opening, etc. temporomandibular relationship disorder that's syndrome.
Dental implant treatment
Including: clinical examination and imaging studies, diagnosis and treatment planning, surgery, denture making and repair, and implant and prosthesis maintenance. According to implant and tooth extraction time, implant surgery can be divided into immediate implantation, delayed instantly (after tooth extraction three months) and delayed planting (after tooth extraction three months and longer). According prosthesis loading with implant time relationship, implants can be divided into immediate loading, early loading and delayed loading.
Implant surgery completed to implant wear this stage, the only implant in the Long short. Implants, you need to follow your doctor's required to maintain oral hygiene and regular (three months, every six months, or every year) review. If subjected to a number of factors prosthesis may appear off, porcelain breakage, fracture, and the abutment screw loosening, implant breakage and other mechanical complications; and peri-implant bone resorption and other biological complications. Seriously affect dental equipments the restoration, aesthetics, the need for surgery or even remove the implant.
Above is about dental implant related presentations, I hope the majority of the friends help. Aesthetic Dental experts also said dental implant prosthetics is a "high, fine, sharp" feature technology, only those with a high standard of technology and equipment conditions of professional bodies in order to carry out this operation, and this professional engaged must possess Stomatology various professional systems knowledge and proficiency strict skills, it is recommended if you need dental implants, please choose a professional regular hospital. If you have additional questions, please consult the online experts.
