Implants 38
Guided bone regeneration
Guided bone regeneration (GBR) uses a barrier membrane or other measures to maintain space for bone growth and encourage regeneration of deficient bone. It may be used with bone graft material around implants or in alveolar ridge defects.
Osseointegration
Osseointegration is the development of a functional connection between living bone and an implant surface. Mechanical fixation immediately after surgery must be distinguished from stability gained through healing.
Bone grafting
Dental bone grafting places bone tissue or substitute material in a deficient area to support reconstruction. Methods and extent vary with goals such as implant preparation, extraction-site management, or regeneration of certain defects.
Bone graft material
Bone graft material is bone tissue or a substitute used to support reconstruction of deficient bone. Autogenous, allogeneic, xenogeneic, and synthetic materials differ in origin and properties and are selected for the intended purpose.
Bone quality and quantity
Bone quality and quantity describe bone properties and available volume, respectively. Implant planning considers internal structure, primary stability conditions, and nearby anatomy as well as bone width and height.
Allogeneic bone grafting
Allogeneic bone grafting uses appropriately processed bone donated by another person. It differs from autogenous grafting using your own harvested bone and xenogeneic grafting using animal-derived material.
Sinus floor elevation
Sinus floor elevation lifts the membrane lining the floor of the maxillary sinus in the upper back-tooth region to create space for bone reconstruction. It is considered when bone height for an implant is insufficient and is not required for every upper-jaw implant.
Socket preservation
Socket preservation manages an extraction socket to limit reductions in bone and gum contour after tooth removal. It may use graft material and a cover or barrier membrane, and is not routinely performed for every extraction.
Dental implant
Dental implant treatment restores the function of missing teeth by using an artificial root placed in the jawbone to support a crown, bridge, or denture.
Implant fixture
An implant fixture is the implant body placed in the jawbone to act as an artificial tooth root.
Implant abutment
An implant abutment is a connector that joins the implant body to a prosthesis, such as a crown, and supports that prosthesis.
Custom abutment
A custom abutment is individually fabricated for the implant position and angle, gum shape, and prosthesis design.
Healing abutment
A healing abutment is temporarily connected to an implant to help the gums heal into a channel and shape for the prosthesis.
Cover screw
A cover screw is a low-profile screw that closes the implant body’s connection and is used in an approach allowing healing beneath the gum.
First-stage implant surgery
First-stage implant surgery is the surgical stage in which the implant body is placed in the jawbone.
Second-stage implant surgery
Second-stage implant surgery exposes the top of an implant that has healed beneath the gum and connects a healing abutment or similar component.
Implant prosthesis
An implant prosthesis is the artificial tooth component, such as a crown, bridge, or denture, supported by implants placed in the jawbone.
Screw-retained versus cement-retained prosthesis
Screw retention and cement retention are two ways of fixing an implant prosthesis: securing it with a screw or bonding it to an abutment with dental cement.
