In terms of restorative methods, there are four major categories: fixed prosthodontics, removable prosthodontics, combined fixed and removable prosthodontics, and implant prosthodontics. Each of these methods has its own advantages and disadvantages. It is possible that all of these restorations may be suitable, or only one or two of them may be suitable. You can choose according to your situation, your doctor’s examination results, and what you value. 1, fixed denture restoration: is the proverbial set of dead teeth, dentures fixed in the mouth by bonding, do not need to take on and off the kind of daily. Fixed restorations can choose from different materials, such as metal, porcelain, all-porcelain and so on. The advantages of fixed prosthetics are: comfort, no foreign body sensation, high chewing efficiency, and aesthetics (in the case of porcelain or all-porcelain). The disadvantages are: the need to grind the teeth on both sides of the missing tooth area. The prerequisite for choosing a fixed restoration is that the teeth on both sides of the missing tooth site are strong enough. 2, movable denture repair: that is to say, set a denture can be removed, with a tray, professionally called abutment, used to increase the force area, stabilize the denture, etc.; also with a few hooks, professionally called the ring, used to fix the denture in the mouth. The movable restoration is the most widely used and can be considered when other methods are not available. There are different base materials to choose from, including: resin base, cobalt-chromium base, pure titanium base, etc. Advantages of removable restorations: Very few adjacent teeth need to be removed, no surgery is required, and they are generally less expensive. Disadvantages of movable restorations: not comfortable enough, foreign body feeling; chewing efficiency is relatively low; inconvenient, need to take off every day for cleaning, often lost after taking off; unsightly, in many cases will expose the metal ring. 3, fixed movable joint restoration: fixed movable joint restoration of dentures also has a tray, but it will use some of the remaining teeth or roots in the mouth to make some special devices, similar to concealed clasps, magnets, etc., used to fix dentures. The application of this method can allow the teeth or roots that could only be extracted in the past to play a full role, and can reduce the ring or not use the ring to ensure the aesthetics, etc. 4, dental implants: known as the third set of human teeth. We restore teeth, of course, the more bionic the better. Implant dentures are the most similar to natural teeth among all the restorative methods available. Its advantages are: comfort, high chewing efficiency and no need to grind adjacent teeth. Disadvantages: the price is higher, nowadays a tooth is usually more than $10,000; it requires surgery, in fact, implant surgery is usually a very small surgery, but some patients are afraid when they hear about surgery; the whole cycle is generally a bit longer. Each of these four types of restorative methods has its own advantages and disadvantages, depending on which one is suitable for you. If three of the four methods are available to you, it depends on what your priorities are, whether it is aesthetic comfort or economical, etc.
