Dental Implant Glossary
Plain-English definitions for every term you will hear during an implant consultation or in a treatment plan. 35+ terms organized by topic.
Updated May 2026 by Dr. Henry Qiu, UCLA-trained oral implantologist, Downey, CA.
This glossary defines the 35+ terms patients hear during a dental implant consultation, organized by topic (anatomy, procedure, materials, healing, cost). Every definition uses plain English first, then notes what changes the clinical or pricing implication for you.
Anatomy and diagnostics
What is Abutment?
The connector piece that sits on top of the implant body and holds your final crown in place. It is custom-shaped to match the emergence profile of a natural tooth. A well-fitted abutment is critical for healthy gum contour and a natural appearance.
What is Crown?
The visible, tooth-shaped cap bonded or screwed onto the abutment after the implant has integrated. At 5D Smiles, crowns are milled from monolithic zirconia for strength and life-like appearance. Zirconia crowns carry a lifetime warranty against fracture at our practice.
What is CBCT scan?
Cone-beam computed tomography produces a 3-D X-ray of the jaw in about 20 seconds. It shows bone width, height, and density, as well as nerve and sinus location, so implant position can be planned digitally before surgery. All implant cases at 5D Smiles begin with a CBCT scan included in the $145 consultation fee.
What is Osseointegration?
The biological process by which living bone grows into the micro-textured surface of a titanium implant, locking it in place without adhesives or cement. The term was coined by Swedish orthopedist Per-Ingvar Branemark in 1952. Typical osseointegration takes 8 to 16 weeks, depending on bone density and the patient's healing biology.
What is Alveolar bone?
The ridge of jawbone that surrounds and supports the roots of teeth. After a tooth is extracted, alveolar bone begins to resorb (shrink) within weeks because it no longer receives the mechanical stimulation of chewing. An implant restores that stimulation, halting further bone loss in the area.
What is Maxilla and mandible?
The maxilla is the upper jaw; the mandible is the lower jaw. Upper-jaw implants are generally more challenging because maxillary bone tends to be less dense and the sinus cavity may limit available bone height. Lower-jaw bone is denser and typically integrates faster.
What is Bone resorption?
The natural process by which the body breaks down and removes bone tissue after tooth loss. Without the stimulation of a tooth root, the alveolar bone shrinks by up to 25 percent in the first year and continues to diminish over time. A dental implant mimics root function and halts resorption, while a denture or bridge does not.
Procedures
What is Single-tooth implant?
One titanium implant body placed in the jaw to replace one missing tooth. It is the most straightforward implant procedure and preserves neighboring teeth (unlike a bridge, which requires grinding down adjacent teeth). A single-tooth implant at 5D Smiles is priced at $3,500 all-inclusive.
What is All-on-4?
A full-arch restoration supported by exactly four implants, with the two back implants angled at 45 degrees to avoid the sinus or nerve canal. It was developed in Europe in the 1990s and popularized for patients with significant bone loss in the back of the jaw. Some practices choose All-on-4 for cost reasons; 5D Smiles standardizes on All-on-6 for better load distribution.
What is All-on-6?
A full-arch restoration supported by six implants placed across the jaw. Two additional implants compared to All-on-4 improve bite force distribution, reduce stress on each individual implant, and provide a safety margin if one implant ever fails. All-on-6 at 5D Smiles starts at $24,000 per arch with bone grafting and sinus lifts included.
What is All-on-X?
A generic term for full-arch implant restorations where the number of implants varies based on the patient's bone volume and anatomy. X is typically 4 to 8. At 5D Smiles, Dr. Qiu determines the implant count for each arch individually after reviewing the CBCT scan.
What is Immediate-load implant?
An implant that receives a temporary crown or bridge on the same day as placement, sometimes called same-day teeth or teeth-in-a-day. This is possible when primary stability (the mechanical grip in fresh bone) is high enough to withstand chewing forces during healing. Not every patient or site qualifies; the CBCT scan guides the decision.
What is Delayed-load implant?
The traditional approach in which a healing cap is placed over the implant and left undisturbed for 8 to 16 weeks to allow full osseointegration before attaching the crown. Delayed loading is preferred when bone quality is poor or when a graft needs to mature. Success rates are slightly higher than immediate load in compromised bone.
What is Sinus lift?
A procedure that adds bone to the upper jaw between the jaw crest and the floor of the maxillary sinus, creating height for implant placement. The lateral window technique opens a small access door in the sinus wall; the crestal (transcrestal) approach pushes sinus membrane upward through the implant orifice itself, which is less invasive and suited for cases needing only a few millimeters of additional height. Both techniques are performed at 5D Smiles at no additional charge in All-on-6 treatment.
What is Bone graft?
Material placed at an extraction site or defect to stimulate new bone formation before or during implant placement. An allograft uses processed cadaveric bone; an autograft uses the patient's own bone taken from the jaw, chin, or hip; a xenograft uses bovine or porcine-derived bone mineral; a synthetic graft uses calcium phosphate ceramics. Each type has different resorption rates and indications; Dr. Qiu selects the material based on defect size and host biology.
What is Zygomatic implant?
An extra-long implant (35 to 52 mm) that anchors in the zygomatic bone (cheekbone) rather than the jaw, bypassing severely atrophic maxillary bone. Zygomatic implants allow full-arch restoration in patients who would otherwise need years of bone grafting and sinus augmentation. They require specialized training and are placed under IV sedation.
What is Mini implant?
An implant with a diameter under 3 mm, used primarily to stabilize removable dentures in patients with minimal bone volume who cannot undergo full implant surgery. Mini implants are less versatile than standard-diameter implants and are not designed to support fixed crowns long-term. They are sometimes offered as a lower-cost bridge solution.
Materials
What is Titanium implant?
The standard implant body material, used clinically since 1965. Grade 4 commercially pure titanium or Grade 5 titanium-aluminum-vanadium alloy is used depending on the manufacturer. Titanium's biocompatibility is exceptional: the immune system does not recognize it as foreign, and bone grows directly onto its surface. Over 60 years of human data support titanium as the benchmark implant material.
What is Zirconia implant?
A one-piece or two-piece implant body made of yttria-stabilized zirconia ceramic. Zirconia is metal-free and tooth-colored, which eliminates the gray shadow that sometimes shows through thin gums with titanium. Long-term survival data are not yet as extensive as for titanium, but 5- to 10-year studies show comparable integration rates. Dr. Qiu discusses zirconia implant candidacy at the consultation.
What is Zirconia crown?
A tooth-colored crown milled from a solid block of zirconia ceramic. Zirconia is harder than natural enamel and highly resistant to fracture, staining, and wear. Monolithic (single-block) zirconia crowns do not chip because there is no softer porcelain veneer over a metal core. 5D Smiles uses monolithic zirconia for all implant-supported crowns.
What is Photofunctionalization (UV activation)?
A surface treatment in which the implant is exposed to ultraviolet light for 15 to 20 minutes immediately before placement. UV energy removes hydrocarbons that accumulate on the titanium surface during storage, restoring the biologically active surface chemistry. Research published in the International Journal of Oral and Maxillofacial Implants shows that photofunctionalized implants achieve osseointegration roughly 30 to 40 percent faster than untreated implants. 5D Smiles applies UV activation to every implant at no additional charge.
What is Platelet-Rich Plasma (PRP) and the Vampire Protocol?
Platelet-rich plasma is concentrated from the patient's own blood by centrifugation and applied to the implant site to release growth factors (PDGF, TGF-beta, VEGF) that accelerate bone and soft-tissue healing. The Vampire Implant Protocol is the name Dr. Qiu uses for this technique at 5D Smiles, adapted from methods taught in his UCLA training. PRP reduces post-operative inflammation and has been shown in multiple RCTs to improve early bone-to-implant contact. The procedure is included with every implant placement at 5D Smiles.
Healing and risk
What is Peri-implantitis?
An inflammatory condition affecting the gum and bone around a functioning implant, analogous to periodontitis around a natural tooth. It is caused by bacterial biofilm accumulation and is the leading cause of late implant failure. Risk factors include poor oral hygiene, smoking, uncontrolled diabetes, and a history of periodontal disease. It is treatable in early stages with professional debridement and antibiotics; advanced cases may require surgical intervention.
What is Implant failure?
Clinically defined as implant mobility, persistent pain, or radiographic bone loss exceeding 0.2 mm per year after the first year. The overall failure rate in healthy patients is 2 to 5 percent. Early failure (within the first 3 months) is usually caused by infection or inadequate primary stability. Late failure (after crown placement) is most often caused by peri-implantitis or overload from bruxism.
What is Smoking-related failure?
Smoking impairs blood flow and immune response at the implant site, roughly doubling the early failure rate compared to non-smokers. Multiple systematic reviews support a failure rate of 6 to 10 percent in active smokers versus 2 to 4 percent in non-smokers. Dr. Qiu recommends stopping smoking at least 2 weeks before surgery and 8 weeks after. The implant can still succeed in smokers who cannot quit, but the higher risk is disclosed explicitly before proceeding.
What is BRONJ (bisphosphonate-related osteonecrosis of the jaw)?
A serious condition in which jaw bone fails to heal after trauma (including surgery) in patients who have taken bisphosphonate medications such as alendronate (Fosamax), zoledronic acid (Reclast), or similar drugs. IV bisphosphonates for cancer carry the highest risk; oral bisphosphonates for osteoporosis carry a much lower but non-zero risk. Patients on these medications must disclose their medication history at consultation so risk can be properly assessed.
What is Drug holiday?
A planned pause in bisphosphonate therapy, typically 2 to 3 months before and 3 months after implant surgery, intended to reduce BRONJ risk. The American Association of Oral and Maxillofacial Surgeons notes that the evidence for drug holidays is limited for oral bisphosphonates but recommends considering them for patients who have been on therapy for 4 or more years. Any change to bisphosphonate medication must be coordinated with the prescribing physician.
What is IV vs. oral sedation?
Oral sedation uses a benzodiazepine (typically triazolam or diazepam) taken 1 hour before the procedure to reduce anxiety; patients remain conscious but feel drowsy. IV sedation delivers propofol and/or midazolam directly into the bloodstream, producing deep sedation with no memory of the procedure. 5D Smiles uses IV sedation with an in-house anesthesia provider for all implant surgeries. Most patients wake up unaware that anything happened.
What is Bruxism?
The habitual clenching or grinding of teeth, often during sleep. Bruxism generates lateral forces that natural teeth can flex away from but that implants, which are rigid in bone, cannot accommodate in the same way. Uncontrolled bruxism is a relative contraindication to implants and is typically managed with a hard nightguard after crown delivery. Patients with severe bruxism may need a splint-retained implant design.
Cost and insurance
What is Consultation fee ($145 at 5D Smiles)?
The $145 consultation includes 45 minutes with Dr. Qiu personally, a full 3-D CBCT scan (valued at approximately $350 at most imaging centers), a detailed treatment plan, and exact all-inclusive pricing in writing. The fee is applied toward the cost of treatment when you proceed. It is not refundable if you do not move forward.
What is All-inclusive pricing?
At 5D Smiles, quoted prices cover every step of the procedure with no add-ons. A $3,500 single implant includes the consult, CBCT scan, implant body, abutment, and final zirconia crown. A $24,000 All-on-6 per arch includes bone grafting, sinus lift if needed, IV sedation, and the fixed zirconia bridge. Practices that quote implant bodies only (excluding the abutment and crown) may appear cheaper but are not comparable.
What is 0% APR financing?
A financing arrangement in which no interest accrues on the financed balance if it is paid in full within the promotional period, typically 12 to 60 months. 5D Smiles offers 0% APR financing through third-party lenders for qualified patients on treatment amounts up to $60,000. Approval is based on creditworthiness and typically takes a few minutes to complete.
What is HSA / FSA eligibility?
Dental implants qualify as a medical expense under IRS Publication 502, making them eligible for payment with Health Savings Account (HSA) or Flexible Spending Account (FSA) funds. Using pre-tax dollars can reduce the effective cost by 22 to 37 percent depending on the patient's tax bracket. Patients should confirm their plan's specific rules with their benefits administrator.
What is PPO vs. HMO coverage?
Preferred Provider Organization (PPO) plans typically reimburse 30 to 50 percent of implant costs up to the annual maximum, which is usually $1,500 to $3,000. Health Maintenance Organization (HMO) dental plans rarely cover implants and instead offer bridges as the covered alternative. 5D Smiles staff verify benefits before your consultation so you know your exact out-of-pocket amount.
What is Medicare exclusion?
Original Medicare (Parts A and B) does not cover dental implants or most dental procedures. Some Medicare Advantage (Part C) plans include limited dental benefits, and a small number specifically cover implants in medically necessary situations (such as tooth loss from a covered illness). Patients should review their Medicare Advantage plan's Evidence of Coverage document or call their plan directly to confirm dental implant coverage.
