What is the best way to restore a missing tooth. The choice of restoration method depends on the number and location of missing teeth. Here are a few restorative options for you to choose from after a tooth loss. Fixed a. Ordinary nickel-chromium alloy porcelain: Advantages: inexpensive, affordable; Disadvantages: gums are easy to color, gums appear black, gray phenomenon. The inner crown is made of base metal nickel-chromium alloy casting, in the complex oral environment, the metal part exposed in the mouth will slowly decompose and release black oxide, resulting in local tissue staining, which is the most important reason why this type of restoration will lead to black lines of gums. Second, cobalt-chromium alloy porcelain teeth: When many patients can not afford the expensive cost of precious metal porcelain teeth, and the ordinary nickel-chromium alloy porcelain metal material holds doubts, practical and economic cobalt-chromium alloy will be the most rational choice; cobalt-chromium alloy was first used to make artificial joints, has good biocompatibility, is now widely used in the field of oral prosthetics, because it does not contain harmful to human body nickel and beryllium elements It has become the ideal choice for the majority of patients because of its safe, reliable and reasonable price. But the light permeability of poor anterior restorations in the fluorescent light blue-black. Third, pure titanium porcelain teeth: advantages: 1, has a very low heat transfer to the living pulp teeth without stimulation. 2, titanium metal specific gravity is only 1 in 4 gold, 1 in 2 cobalt-chromium metal. strength is the most metal. 3, titanium is semi-blocking to X-rays, is other metal materials do not have. 4, titanium metal has excellent biocompatibility and corrosion resistance. It does not stimulate gum recession, no discoloration, no redness and swelling, safe and reliable. The disadvantage is that pure titanium metal properties lead to poor bonding with the porcelain layer, chewing force is too large when easy to collapse porcelain. Fourth, precious metal porcelain teeth: gold-platinum alloy porcelain crowns, gold deposited porcelain crowns, silver-palladium alloy porcelain crowns together known as precious metal porcelain crowns, the inner crown are gold-platinum alloy, 99.99% electroplated pure gold, silver-palladium alloy, they are inert metal biocompatibility is excellent, gold porcelain bonding force is super strong, soft color without black refraction does not affect the magnetic resonance and other instrument inspection. Become the best choice instead of pure titanium and titanium porcelain. Fifth, Yi Yujia cast porcelain 3 generation (all-porcelain) All-porcelain system after 15 years of clinical verification, twenty-five million restorations into the wearer to prove that it has a long-term real natural effect; excellent biocompatibility, ideal light permeability, perfect cosmetic effect, the current clinical have a large number of successful cosmetic restoration cases. However, its hardness is not as high as zirconia all-ceramic crowns. Not suitable for posterior fixed bridge denture design. Six, computer cutting zirconia all-ceramic (crown) the world’s only computer-aided design fully automatic mechanical cutting zirconia all-ceramic teeth, designed specifically for the anterior jaw premolars have unparalleled light transmission and strength, you can achieve the best aesthetic results, can use traditional bonding methods. The disadvantage is that the current cost is higher. Seven, all-porcelain veneers: If there is no major tooth loss, but only poor color, we recommend that you use this cosmetic dentistry’s most minimally invasive restorative method, which can achieve near-perfect aesthetic results. Advantages: The amount of tooth abrasion is only equivalent to about 1 in 3 of conventional porcelain restorations, and does not destroy the adjacent points and hard tissues of the teeth on the lingual side, the taste does not change. Light transmission, cosmetic effect is remarkable. Dental implants are implants made of high-tech synthetic materials implanted in the alveolar bone of the missing area, and the other end is exposed to the oral cavity to create a realistic denture at the exposed end; they are composed of implants and implant-supported superstructure; in common parlance, dental implants are implanted in the alveolar bone of the missing area through alveolar surgery as artificial tooth roots, and then The implant is then used as the basis for restoring the missing tooth. Dental implants are very small and safe, no hospitalization is required, the surgery is completely painless and you can eat after the surgery. Removable partial denture 2. If you have more missing teeth, you can choose this kind of removable denture with cast steel brackets, which is inexpensive and easy to clean. 3.Invisible denture Suitable for transitional denture repair in the anterior region. No ring design is beautiful and good retention. Because of the pressure on the gum stimulation should not be used for a long time. 4, full denture elderly people all missing teeth, we should consider setting the whole mouth, the most common is this, of course, you can also choose implants, good implant effect, the cost is also higher fixed + movable 1, sleeve crown attachment (double crown): the use of sleeve crown internal and external double crown structure, the denture and the abutment teeth connected to the restoration form. The sleeve crown consists of an inner crown and an outer crown, the inner crown is bonded to the abutment teeth, the outer crown is connected to the other components of the denture as a whole, the denture through the friction between the inner crown and the outer crown to produce retention force, so that the denture to achieve good retention The sleeve crown denture has unique characteristics: as with all other precision attachments, it can be movable denture of the advantages of self-removal, easy to clean and fixed denture of good functional recovery, the advantages of the foreign body feeling is small It is especially suitable for denture restoration after treatment of periodontal disease, and can play a good role as a periodontal splint. 2.Precision attachment The design and clinical trial of precision attachment is successful, representing the latest level of development of dental technology today. The system is highly functional and can be easily and conveniently removed by the patient. Its applicability ranges from indications for gap restorations, to unilateral and bilateral free missing restorations, to remaining single teeth or pile crown connections. 3.Bolted precision attachment is the best design for missing teeth that cannot be directly restored with fixed prosthesis 4.Tai Chi clasp Tai Chi clasp is a simple, reliable and highly adaptable attachment system for removable restorations that we developed to meet the needs of professional dentists. The Taiji Clasp is currently the most widely recognized flexible dental attachment. In cases of removable partial denture treatment, dental support and implant-supported overdentures, the Taiji Clasp is the best choice for experienced and new dental professionals who are just beginning to work with precision attachments. 5.Magnetic attachment Preserve residual crowns and roots for overdenture, use the magnetism of magnets to enhance retention; use Japanese imported magnets, good retention and high chewing efficiency Significantly higher than the stable retention of full dentures.
