    Management of Missing Teeth

    The teeth are usually absent from the dental arch congenital or as a result of the disease, including tooth decay and periodontal breakdown are the most common. While it is not axiomatic that a missing tooth must always be replaced, there are many occasions it is desirable to improve the appearance, chewing or speech function, or sometimes to avoid damaging changes in the dental arches, as overeruption or tilt / drifting of the teeth. Tooth loss is also followed by alveolar bone resorption, which aggravates resulting tissue deficits.

    In most countries with an oral care services is considerable component of the work of the dental team directed toward the prevention of tooth loss, repair damaged teeth, and replacing those missing, along with its supporting tissues. When patients are toothless, treatment for teeth loss has been largely restricted to the use of complete dentures, however, the timing, the potential treatments are more numerous, since a large variety of techniques can be used to stabilize prosthesis linking them to natural teeth. Removable partial dentures (DPR) are widely used due to
    versatility and can yield long-term effective appropriate circumstances. They do, however, suffer from still relatively bulky, often require metal components can be difficult to hide are patient removable, and are inherently less stable than a fixed bridge that is secured permanently to one or more teeth. These can be both traditional designs on the extensive preparation pillars, or more modern and less destructive adhesive techniques. In general, DPR are used to management of missing teeth or alveolar significantly extended resorption and where there are advantages in relative simplicity of manufacture and replacement. Fixed restorations are usually less versatile and more expensive to provide, but have advantages related to stability and reduced volume.

    Doctors have long sought to provide their patients with an artificial analogue of natural teeth and variety of materials and techniques have been used to it. However, it was not possible to replicate the periodontal tissues and alternatively strategies have therefore been adopted. These have was based on the principles of the creation and maintenance an interface between the implant and the surrounding bone, which is capable of transmitting the load, associated with healthy tissue adjacent predictable results and high success rate. This result proved elusive until the discovery of the phenomenon of osseointegration.As i will discuss osseointegration in my next blog post.
