A
- Abutment · also called implant abutment, implant connector
An abutment is the small connector that attaches to a dental implant post and supports the replacement tooth above the gumline. It is machined to fit the implant on one end and hold a crown, bridge, or denture on the other, and it is usually attached once the bone has bonded to the implant.
- Acrylic Full-Arch Prosthesis · also called acrylic hybrid, acrylic implant bridge
An acrylic full-arch prosthesis is a set of replacement teeth for an entire jaw made mainly from acrylic resin, often reinforced with a metal framework, that attaches to dental implants. Acrylic is lighter and generally easier to adjust or repair than zirconia, but it is more prone to wear, staining, and chipping over time.
- All-On-4 · also called All-on-Four, All on 4 dental implants
All-On-4 is a full-arch treatment in which a fixed bridge replacing all the teeth in the upper or lower jaw is supported by four dental implants. The back implants are often angled to reach denser bone, which can reduce or avoid the need for bone grafting in some patients.
- All-On-X · also called All-on-6, full-mouth dental implants, full-arch implants
All-On-X is a general term for full-arch implant treatment in which a fixed bridge replacing every tooth in one jaw is supported by a variable number of implants, commonly four to six per arch. The number and position of the implants are chosen from imaging to suit the patient's bone and bite.
B
- Bar-Retained Overdenture · also called bar overdenture, bar-supported denture
A bar-retained overdenture is a removable denture that clips onto a custom metal bar connecting two or more dental implants. The bar splints the implants together and spreads chewing forces across them, giving a firm fit, while the denture still comes out for daily cleaning.
- Bone Density · also called bone quality, jawbone density
Bone density describes how thick and solid the jawbone is at a planned implant site. Denser bone generally holds an implant more firmly at placement, while softer bone may call for a different implant design, a longer healing period, or grafting. Dentists assess it from CT imaging and during surgery.
- Bone Graft · also called dental bone graft, bone grafting
A bone graft is a procedure that adds grafting material to an area of the jaw where the bone is too thin or too short to support an implant. The material, which may come from the patient, a processed donor or animal source, or a synthetic mineral, acts as a scaffold that the body gradually replaces with its own new bone.
- Bone Loss · also called bone resorption, jawbone loss, alveolar bone loss
Bone loss, also called bone resorption, is the gradual shrinking of the jawbone that usually follows tooth loss, because the bone no longer receives stimulation from a tooth root. It can reduce the height and width of bone available for implants, change facial contours, and loosen the fit of dentures over time.
C
- Cement-Retained Crown · also called cemented implant crown
A cement-retained crown is an implant crown that is bonded onto its abutment with dental cement, much like a crown on a natural tooth. It has no visible screw access hole, which can help appearance, but it is harder to remove for repairs, and excess cement must be cleaned away carefully to protect the surrounding gum.
- Crown · also called implant crown, dental crown, cap
A crown is the visible, tooth-shaped part of a dental restoration, custom-made to match the shape and shade of the neighboring teeth. On a dental implant, the crown attaches to the abutment by a screw or by cement, and it is usually fabricated in a dental lab from a ceramic such as porcelain or zirconia.
- CT Scan (CBCT) · also called CBCT, cone beam CT, dental CT scan, 3D dental scan
A dental CT scan, usually a cone-beam computed tomography (CBCT) scan, is a three-dimensional X-ray image of the jaws and teeth. It shows bone height, width, and density, the path of nerves, and the position of the sinuses, which dentists use to plan the size, position, and angle of a dental implant before surgery.
D
- Dental Bridge · also called fixed bridge, traditional bridge, tooth-supported bridge
A dental bridge is a fixed restoration that replaces one or more missing teeth by joining an artificial tooth to crowns placed on the natural teeth on either side of the gap. A traditional bridge usually requires reshaping those neighboring teeth, and because it rests on the gum, it does not stimulate the jawbone beneath the missing tooth.
- Dental Implant · also called tooth implant, implant
A dental implant is a small post, usually titanium, that is placed in the jawbone to replace the root of a missing tooth. Once the bone bonds to it, the implant supports an abutment and a crown, bridge, or denture, creating a replacement tooth that is anchored in bone rather than resting on the gum.
- Dry Socket · also called alveolar osteitis
Dry socket is a painful complication of tooth extraction in which the blood clot in the empty socket dissolves, dislodges, or fails to form, leaving the underlying bone exposed. It typically causes throbbing pain that worsens in the days after an extraction instead of improving, and it is treated by a dentist, often with a medicated dressing.
F
- Full-Arch Bridge · also called full-arch prosthesis, fixed full-arch restoration, implant-supported full-arch bridge
A full-arch bridge is a fixed set of replacement teeth that spans an entire upper or lower jaw and is secured to several dental implants. Unlike a removable denture, it is usually screwed in place and taken off only by a dental team for maintenance, and it may be made from zirconia, acrylic, or other materials.
H
- Healing Cap · also called healing abutment, healing collar, cover screw
A healing cap is a small temporary component placed on a dental implant to protect its connection while the site heals. A low-profile version that sits under the gum is often called a cover screw; a taller one that passes through the gum, called a healing abutment, also shapes the gum tissue for the future crown.
- Hybrid Denture · also called hybrid prosthesis, fixed hybrid, fixed denture, permanent dentures
A hybrid denture is a fixed full-arch prosthesis, traditionally made of acrylic teeth and gums over a metal framework, that is screwed onto dental implants. It combines the appearance of a denture with the fixed stability of a bridge, and it can be removed only by a dental professional.
I
- Immediate Implant Placement · also called same-day implant placement, extraction and immediate implant
Immediate implant placement is a technique in which a dental implant is placed into the tooth socket during the same visit that the tooth is extracted. It can reduce the number of surgeries, but it depends on healthy surrounding bone, the absence of active infection, and enough implant stability at the time of placement.
- Immediate Loading · also called immediate load, same-day teeth, teeth in a day, same-day implants
Immediate loading is an approach in which a temporary tooth, bridge, or full-arch prosthesis is attached to dental implants on the day of surgery or shortly after, rather than after the bone has fully healed. It is usually possible only when the implants are very stable at placement, and the temporary teeth are typically protected from heavy chewing during healing.
- Implant Consultation · also called dental implant consultation, implant evaluation
An implant consultation is an evaluation visit in which a dentist reviews a patient's dental and medical history, examines the mouth, and takes imaging to determine whether dental implants are suitable. It often ends with a discussion of treatment options and a written treatment plan and estimate before any procedure is scheduled.
- Implant Failure · also called failed dental implant, implant rejection
Implant failure is the loss or removal of a dental implant because it did not bond to the bone or later lost its bone support. Early failure happens when osseointegration does not occur during healing; late failure is most often linked to peri-implantitis, excessive bite forces, or health factors such as smoking or uncontrolled diabetes.
- Implant Post · also called implant fixture, implant body, implant screw
An implant post is the part of a dental implant that is placed in the jawbone to act as an artificial tooth root. It is usually a threaded titanium screw or cylinder, and once the bone has bonded to it, it serves as the anchor for the abutment and the replacement tooth.
- Implant-Supported Bridge · also called implant bridge
An implant-supported bridge is a fixed bridge that replaces several missing teeth in a row and is anchored to dental implants rather than to natural teeth. Because two or more implants can carry a span of teeth, it can replace more teeth than the number of implants placed, without reshaping neighboring healthy teeth.
- Implant-Supported Denture · also called implant-retained denture, snap-in dentures, implant dentures
An implant-supported denture is a full denture held in place by dental implants instead of relying on suction or adhesive. The term most often refers to a removable overdenture that snaps onto attachments on the implants, though fixed full-arch designs are also supported by implants.
- Itemized Estimate · also called itemized treatment estimate, written estimate, implant quote
An itemized estimate is a written cost breakdown that lists each part of a dental treatment plan as a separate line, such as imaging, extractions, grafting, the implant post, the abutment, the crown, and sedation. It shows exactly which components a quoted price includes, so patients can compare plans from different offices on equal terms.
- IV Sedation · also called intravenous sedation, twilight sedation, conscious sedation
IV sedation is a form of sedation in which calming medication is given through a vein, allowing the provider to adjust the level of sedation during a procedure. Patients usually keep breathing on their own and can respond, but feel deeply relaxed and may remember little afterward; it requires monitoring and an escort home.
L
- Local Anesthetic · also called local anesthesia, numbing injection, dental numbing
A local anesthetic is a medication injected near a treatment site to numb a specific area of the mouth while the patient stays fully awake. It blocks pain signals from that area, so patients usually feel pressure or vibration but not sharp pain, and it is commonly used for implant surgery whether or not sedation is added.
- Locator Attachment · also called locators, snap attachment, implant denture attachment
A locator attachment is a small, low-profile snap fitting that is screwed onto a dental implant so a removable overdenture can click into place. Matching housings in the denture hold replaceable nylon inserts that grip the attachment; the inserts wear with daily use and are changed periodically to restore a secure fit.
M
- Maryland Bridge · also called resin-bonded bridge, bonded bridge
A Maryland bridge is a conservative type of dental bridge in which an artificial tooth is held by thin metal or ceramic wings bonded to the backs of the neighboring teeth. It requires little or no reshaping of those teeth, but it is less strong than other bridges and is generally used for front teeth or as a temporary option.
O
- One-Stage Implant Surgery · also called single-stage implant surgery, non-submerged implant
One-stage implant surgery is an approach in which the implant is placed with a healing abutment that extends through the gum from the start, so the implant does not need to be surgically uncovered later. It avoids a second surgical step and is used when the bone and gum conditions allow the implant to heal while exposed.
- Oral Sedation · also called sedation pill, oral conscious sedation
Oral sedation is a form of sedation in which a calming medication is taken by mouth as a pill, usually shortly before a dental procedure. It produces relaxation and drowsiness while the patient stays awake and responsive, and because the effects linger, patients generally need someone to drive them home.
- Osseointegration · also called implant integration, bone fusion
Osseointegration is the process by which living jawbone grows directly against the surface of a dental implant and bonds to it, anchoring the implant firmly like a natural tooth root. It happens gradually during healing after placement, and it is the reason most implants are given time to heal before they carry a final tooth.
- Overdenture · also called implant overdenture, snap-on denture
An overdenture is a removable denture that fits over and is held in place by dental implants, or occasionally by retained tooth roots. It snaps onto individual attachments or a bar, which makes it much steadier than a conventional denture while still allowing the wearer to take it out for cleaning.
P
- Panoramic X-Ray · also called panorex, pano, panoramic radiograph, OPG
A panoramic X-ray is a two-dimensional dental image that captures the upper and lower jaws, all the teeth, and nearby structures in a single wide view. It gives a useful overview of tooth and bone health, but because it is flat, it cannot measure bone width or map nerves in three dimensions the way a CT scan can.
- Partial Denture · also called removable partial denture, partial, RPD
A partial denture is a removable appliance that replaces some missing teeth with artificial teeth set in a gum-colored base, held in place by clasps or attachments on the remaining natural teeth. It is less invasive than implants, but it rests on the gums, can shift during use, and does not stimulate the bone beneath the gaps.
- Peri-Implant Mucositis · also called implant gum inflammation
Peri-implant mucositis is inflammation of the gum tissue around a dental implant without loss of the supporting bone. It usually shows as redness, swelling, or bleeding when brushing, and it is generally reversible with professional cleaning and better home care, but if left untreated it can progress to peri-implantitis.
- Peri-Implantitis · also called implant infection, gum disease around an implant
Peri-implantitis is an inflammatory disease of the gum and bone around a dental implant, usually driven by bacterial plaque, that causes progressive loss of the bone supporting the implant. Signs can include bleeding, pus, gum recession, and deepening pockets, and if it is not treated it can eventually loosen the implant.
- Periodontitis · also called gum disease, periodontal disease
Periodontitis is an advanced form of gum disease in which bacterial infection spreads below the gumline and destroys the bone and fibers that hold teeth in place. It is a common cause of tooth loss in adults, and it is usually treated and brought under control before dental implants are placed.
- Provisional Prosthesis · also called temporary prosthesis, temporary teeth, temporary bridge, provisional
A provisional prosthesis is a temporary tooth, bridge, or denture worn while dental implants heal and before the final restoration is made. It protects the surgical sites, lets the patient eat and speak during healing, and gives the dental team a chance to test the bite and appearance before the permanent teeth are fabricated.
R
- Root Canal · also called root canal therapy, endodontic treatment
A root canal is a treatment that saves a natural tooth by removing infected or inflamed pulp from inside it, cleaning and sealing the canals, and usually covering the tooth with a crown. It is often considered before extraction when the tooth has enough healthy structure to be restored, making it a common alternative to an implant.
S
- Screw-Retained Crown · also called screwed implant crown
A screw-retained crown is an implant crown fastened to the implant or abutment with a small screw passed through an access hole in the crown, which is then sealed with tooth-colored filling material. Because it can be unscrewed, it is easier to remove for cleaning or repair, and it avoids leftover cement under the gum.
- Sinus Lift · also called sinus augmentation, sinus graft, sinus floor elevation
A sinus lift is a bone grafting procedure for the upper back jaw in which the membrane lining the maxillary sinus is gently raised and graft material is placed beneath it. It adds bone height where the sinus sits too close to a planned implant site, so an implant can be placed without entering the sinus.
- Socket Preservation · also called ridge preservation, socket graft, extraction site graft
Socket preservation is a minor bone grafting procedure in which graft material is placed into a tooth socket right after an extraction, often covered by a protective membrane. It helps limit the shrinking of bone and gum that normally follows tooth removal, which can make later implant placement simpler.
- Surgical Guide · also called surgical stent, implant guide, guided implant surgery
A surgical guide is a custom template, usually 3D-printed from a patient's CT scan and digital treatment plan, that fits over the teeth, gums, or bone during implant surgery. It directs the drill to the planned position, angle, and depth for each implant, helping transfer the digital plan accurately into the mouth.
T
- Titanium · also called titanium implant, titanium alloy
Titanium is a strong, lightweight, biocompatible metal that is the usual material for dental implant posts. Bone bonds readily to its surface through osseointegration, and it is used either as commercially pure titanium or as a titanium alloy, with a long track record in dentistry and orthopedic medicine.
- Tooth Extraction · also called extraction, tooth removal, pulling a tooth
A tooth extraction is the removal of a tooth from its socket in the jawbone, performed when a tooth is too damaged, infected, or loose to keep. When an implant is planned, an extraction may be paired with socket preservation or immediate implant placement, depending on the condition of the bone and gum.
- Treatment Plan · also called dental treatment plan, implant treatment plan
A treatment plan is a written outline of the dental procedures recommended for a patient, listed in the order they will be performed, from any extractions or grafting through implant placement and the final teeth. A complete plan usually explains the reason for each step, the alternatives considered, and the itemized costs involved.
- Two-Stage Implant Surgery · also called submerged implant, two-stage implant placement
Two-stage implant surgery is an approach in which the implant is placed and then covered by the gum while it bonds to the bone. In a brief second procedure, the gum is opened to expose the implant and a healing abutment or abutment is attached, a sequence often chosen when grafting is done or initial stability is limited.
Z
- Zirconia Full-Arch Prosthesis · also called zirconia bridge, zirconia full-arch bridge, monolithic zirconia
A zirconia full-arch prosthesis is a fixed bridge replacing all the teeth in one jaw, milled from zirconia, a very hard tooth-colored ceramic, and secured to dental implants. It resists wear and staining well, but it is more rigid than acrylic, and if it chips or fractures, repairs are generally more involved.
- Zirconia Implant · also called ceramic implant, metal-free implant
A zirconia implant is a dental implant post made from zirconium dioxide, a tooth-colored ceramic, instead of the more common titanium. It is a less common, metal-free alternative that some patients choose for appearance or personal preference, and it is often made as a single piece, which can limit restorative options in some cases.
