Failure of a dental implant is often related to the failure of the implant to osseointegrate correctly with the bone, or vice versa. [4] A dental implant is considered to be a failure if it is lost, mobile or shows peri-implant (around the implant) bone loss of greater than 1.0 mm in the first year and greater than 0.2 mm a year after.

A radiograph two years after implant placement, then seven years later in a heavy smoker, demonstrating progression of bone loss due to peri-implantitis. Peri-implantitis is a destructive inflammatory process affecting the soft and hard tissues surrounding dental implants. [1]
Peri-implant mucositis is defined as an inflammatory lesion of the peri-implant mucosa in the absence of continuing marginal bone loss. [1]The American Academy of Periodontology defines peri‐implant mucositis as a disease in which inflammation of the soft tissues surrounding a dental implant is present without additional bone loss after the initial bone remodeling that may occur during ...
The head of the zygoma implant is engineered to allow prosthesis attachment at a 45-degree angle to the long axis of the implant. [7] Zygomatic implants can be used in patients who do not have any teeth in the upper jaw, patients who have heavily broken down teeth or very mobile teeth due to diseases such as generalised aggressive periodontitis ...
Overdenture is any removable dental prosthesis that covers and rests on one or more remaining natural teeth, the roots of natural teeth, and/or dental implants. [1] It is one of the most practical measures used in preventive dentistry. Overdentures can be either tooth supported (conventional / immediate) or implant supported.
A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
The process of preparation usually involves cutting the tooth with a rotary dental handpiece and dental burrs, a dental laser, or through air abrasion (or in the case of atraumatic restorative treatment, hand instruments), to make space for the planned restorative materials and to remove any dental decay or portions of the tooth that are ...
Occasionally, a dentist may recommend dental implants for a patient, but that patient does not have enough upper jaw bone to accommodate a dental implant. In this case, the dentist will recommend a sinus lift. A sinus lift is a surgical procedure in which bone is grafted onto the upper jaw.
