A dental implant is a prosthesis that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown, bridge, denture, or facial prosthesis or to act as an orthodontic anchor. The basis for modern dental implants is a biological process called osseointegration, in which materials such as titanium or zirconia form an intimate bond to the bone. The implant fixture is first placed so that it is likely to osseointegrate, then a dental prosthetic is added. A variable amount of healing time is required for osseointegration before either the dental prosthetic is attached to the implant or an abutment is placed which will hold a dental prosthetic/crown.
Osseointegration is the direct structural and functional connection between living bone and the surface of a load-bearing artificial implant. A more recent definition defines osseointegration as "functional ankylosis ", where new bone is laid down directly on the implant surface and the implant exhibits mechanical stability. Osseointegration has enhanced the science of medical bone and joint replacement techniques as well as dental implants and improving prosthetics for amputees.
Maxillary sinus floor augmentation is a surgical procedure which aims to increase the amount of bone in the posterior maxilla, in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane and placing a bone graft.
Crown lengthening is a surgical procedure performed by a dentist, or more frequently a periodontist, where more tooth is exposed by removing some of the gingival margin (gum) and supporting bone. Crown lengthening can also be achieved orthodontically by extruding the tooth.
Gingivectomy is a dental procedure in which a dentist or oral surgeon cuts away part of the gums in the mouth.
Carl E. Misch was an American prosthodontist recognized internationally for his clinical and academic contributions to the field of implant dentistry.
Hessam Nowzari is the Director of the University of Southern California Advanced Periodontics program, since 1995, and is a diplomate of the American Board of Periodontology.
Resonance frequency analysis (RFA) is a method used to determine stability in dental implants. The stability is presented as an implant stability quotient (ISQ) value. The higher the ISQ value the higher the stability.
In dentistry, an abutment is a connecting element. This is used in the context of a fixed bridge, partial removable dentures and in implants. The implant fixture is the screw-like component that is osseointegrated.
Peri-implantitis is a destructive inflammatory process affecting the soft and hard tissues surrounding dental implants. The soft tissues become inflamed whereas the alveolar bone, which surrounds the implant for the purposes of retention, is lost over time.
In the United States and Canada, there are twelve recognized dental specialties in which some dentists choose to train and practice, in addition to or instead of general dentistry. In the United Kingdom and Australia, there are thirteen.
Hom-Lay Wang (王鴻烈) is a Taiwanese-born periodontist and director of the graduate periodontal program at University of Michigan School of Dentistry.
The European Federation of Periodontology (EFP) is a non-profit organisation dedicated to promoting awareness of periodontal science, the science and clinical practice of periodontics and implant dentistry, and the importance of gum health. Its guiding vision is “Periodontal health for a better life.”
Zygoma implants are different from conventional dental implants in that they anchor in to the zygomatic bone rather than the maxilla. They may be used when maxillary bone quality or quantity is inadequate for the placement of regular dental implants. Inadequate maxillary bone volume may be due to bone resorption as well as to pneumatization of the maxillary sinus or to a combination of both. The minimal bone height for a standard implant placement in the posterior region of the upper jaw should be about 10 mm to ensure acceptable implant survival. When there is inadequate bone available, bone grafting procedures and sinus lift procedures may be carried out to increase the volume of bone. Bone grafting procedures in the jaws have the disadvantage of prolonged treatment time, restriction of denture wear, morbidity of the donor surgical site and graft rejection.

Michael A. Pikos is an American implant oral and maxillofacial surgeon known as the CEO/Founder of Coastal Jaw Surgery and Pikos Institute.
A root-analog dental implant (RAI) – also known as a truly anatomic dental implant, or an anatomical/custom implant – is a medical device to replace one or more roots of a single tooth immediately after extraction. In contrast to common titanium screw type implants, these implants are custom-made to exactly match the extraction socket of the specific patient. Thus there is usually no need for surgery.
