Peri-implantitis is a destructive inflammatory process affecting the soft and hard tissues surrounding dental implants. [1] The soft tissues become inflamed whereas the alveolar bone (hard tissue), which surrounds the implant for the purposes of retention, is lost over time.
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.

post only vs. with additional single-circle ring [15] In a classic case one of the best designs for a post to decrease the risk of failure is the narrowest and longest smooth, parallel post that one can fit into the post space. Utilizing the longest possible post ensures that the forces transmitted from the crown are distributed over as much of ...
Implants preserve the integrity of the teeth adjacent to the edentulous area, and it has been shown that dental implant therapy is less costly and more efficient over time than tooth-supported FPDs for the replacement of one missing tooth. The major disadvantage of dental implant surgery is the need for a surgical procedure. [17]
Periodontology or periodontics (from Ancient Greek περί, perí – 'around'; and ὀδούς, odoús – 'tooth', genitive ὀδόντος, odóntos) is the specialty of dentistry that studies supporting structures of teeth, as well as diseases and conditions that affect them.
A fracture or decementation of a post or loosening of the abutment screw of an implant could be the result of dissolved cement, secondary caries, use of a weak post, or excessive occlusal forces. [8] Oral home care needs to remain at a high standard, brushing twice a day for the duration of two minutes with the use of fluoridated tooth paste.
An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar) which is closely related to the antral floor.
The root canal filling material (3, 4, and 10) does not extend to the end of the tooth roots (5, 6 and 11). The dark circles at the bottom of the tooth roots (7 and 8) indicated infection in the surrounding bone. Recommended treatment is either to redo the root canal therapy or extract the tooth and place dental implants.
