What is the first step in the typical treatment plan for placing a dental implant?
- A Attaching the abutment onto the osseointegrated implant body
- B Waiting through the full osseointegration healing period
- C Consultation and planning with imaging and history review
- D Suturing the gum tissue closed after implant placement
Correct answer: Consultation and planning with imaging and history review
Before any surgical steps, the dentist performs consultation, reviews medical history, and obtains imaging to assess bone and plan implant placement. This planning phase is essential for determining suitability and strategy.
Which of the following is the material most commonly used for the implant body in dental implant systems?
- A Gold alloy
- B Titanium
- C Porcelain
- D Stainless steel
Correct answer: Titanium
Titanium is widely used because it is biocompatible and integrates well with bone, making it the standard for dental implants.
What is the term for the process by which the jawbone fuses to the surface of a dental implant?
- A Peri-implantitis
- B Platform matching
- C Osseointegration
- D Abutment placement
Correct answer: Osseointegration
Osseointegration is the biological process where bone grows around and bonds to the implant surface, creating a stable foundation for the prosthesis.
During the surgical placement of an implant, what is the typical sequence after making an incision in the gum tissue?
- A Attach the crown first, and only then drill into the bone
- B Drill bone, insert implant post, place healing cap
- C Place the healing cap first, and then drill the bone
- D Suture the gum closed first, and then drill the bone
Correct answer: Drill bone, insert implant post, place healing cap
Once the gum is opened, the clinician drills into the jawbone, inserts the implant post, then often places a healing cap or closes the site to allow for healing.
What is the role of the dental assistant during implant surgery?
- A Diagnose the quality of the bone at the chosen implant site
- B Manage suction, pass instruments, and prepare setup
- C Decide on the implant size and placement angle used
- D Perform the full surgical bone drilling sequence
Correct answer: Manage suction, pass instruments, and prepare setup
Dental assistants support the surgeon by passing instruments, handling suction, maintaining asepsis, and preparing the operatory; they do not perform surgical decision-making or drilling.
Why might a bone graft be necessary before implant placement?
- A To speed up osseointegration
- B To provide sufficient bone volume and density if the jawbone is too thin or soft
- C To avoid the need for a healing cap
- D To reduce the cost of the implant
Correct answer: To provide sufficient bone volume and density if the jawbone is too thin or soft
If the jawbone lacks adequate volume or density, grafting adds bone (or substitutes) to create a stable foundation capable of supporting an implant. Without this, implant stability is compromised.
What does an abutment refer to in implant dentistry?
- A The titanium screw that is placed directly into the jawbone
- B The temporary healing cap used during the osseointegration phase
- C The connector on the implant that supports the final crown
- D The suture material used to close the gum tissue over it
Correct answer: The connector on the implant that supports the final crown
An abutment is the component attached to the implant body, which extends through the gum and supports the final prosthetic crown or bridge.
What is “platform switching” in the context of implant restorations?
- A Using a narrower abutment than the implant platform to cut bone loss
- B Matching the abutment and the implant platform diameters exactly to each other
- C Switching from titanium to zirconia abutments partway through
- D Replacing the healing cap with the final crown immediately
Correct answer: Using a narrower abutment than the implant platform to cut bone loss
Platform switching involves placing a narrower abutment on a wider implant platform, which has been shown to help preserve crestal bone levels around implants.
What method can be used to assess stability of an implant during the healing phase?
- A Visual inspection only
- B Resonance frequency analysis (RFA)
- C Measuring gum swelling
- D Patient feedback on pain
Correct answer: Resonance frequency analysis (RFA)
Resonance frequency analysis (RFA) measures implant stability, providing an Implant Stability Quotient (ISQ) score to help determine readiness for prosthesis loading.
Which factor may adversely affect the long-term success of a dental implant?
- A Good oral hygiene around the implant
- B Smoking and poor bone quality at the implant site
- C Use of titanium implant body
- D Appropriate osseointegration period
Correct answer: Smoking and poor bone quality at the implant site
Smoking and inadequate bone quality can impair healing and osseointegration, increasing risk of implant failure.
Which postoperative instruction is commonly given after implant surgery by the dental assistant or dentist?
- A Resume hard chewing on the implant area right away immediately
- B Use straws frequently and rinse the mouth vigorously
- C Keep to a soft-food diet and gentle oral hygiene
- D Use an abrasive toothpaste over the surgical site
Correct answer: Keep to a soft-food diet and gentle oral hygiene
After implant placement, patients are typically advised to eat soft foods and maintain gentle oral hygiene to avoid disturbing the surgical site and promote healing.
What does “immediate-load” dental implant refer to?
- A Loading the implant only after a full 6 months of osseointegration has completed
- B Using the implant body as a temporary denture anchor
- C Fitting a prosthesis soon after placement without a long healing delay
- D Placing implants without any anesthesia
Correct answer: Fitting a prosthesis soon after placement without a long healing delay
Immediate-load implants receive a provisional (or sometimes final) prosthesis shortly after placement, avoiding a prolonged edentulous period.
Who is responsible for inventory of implant components (implants, abutments, healing caps) in a dental implant practice?
- A Patient
- B Dental assistant
- C Implant manufacturer directly
- D Only the dentist
Correct answer: Dental assistant
Dental assistants often manage the inventory of implant components like abutments, healing caps and ensure the correct items are available for each procedure.
What type of prosthesis might be supported by implants for patients missing all teeth in an arch?
- A The patient who received the implant
- B The dental assistant
- C The implant manufacturer directly
- D Only the dentist
Correct answer: The dental assistant
For fully edentulous arches, implants can support overdentures or fixed full-arch prostheses, offering improved stability, function, and preservation of bone.
During implant prosthesis delivery, what must be checked before final torque of abutment screw in a screw-retained restoration?
- A The color of the prosthesis matches the shade guide
- B Complete seating and radiographic fit
- C Patient's blood pressure
- D Time of day
Correct answer: Complete seating and radiographic fit
Before torquing the abutment screw, the prosthesis must be fully seated correctly and verified radiographically to avoid misfit, which could lead to complications.
Which of the following is a critical component for maintaining long-term health of a dental implant after placement?
- A Avoiding dental checkups entirely after the crown is delivered
- B Regular oral hygiene and professional maintenance
- C Never replacing the crown under any circumstances
- D Rinsing with harsh chemicals daily
Correct answer: Regular oral hygiene and professional maintenance
Good oral hygiene around implants and regular professional check-ups help prevent peri-implant disease and ensure implant longevity.
What is a “healing abutment” used for in implant dentistry?
- A To permanently hold the definitive crown firmly in its final position
- B To shape the gum tissue and maintain access during healing
- C To cement the prosthesis
- D To measure bone density
Correct answer: To shape the gum tissue and maintain access during healing
A healing abutment is placed after implant insertion to guide soft tissue healing and maintain a pathway for future restoration while osseointegration proceeds.
Why is the patient’s medical history and habits (like smoking) reviewed before recommending implants?
- A To choose the crown color that best suits the patient's smile and complexion
- B Because certain systemic conditions or habits may impair osseointegration
- C To set the fee for the implant
- D To determine the size of the implant post
Correct answer: Because certain systemic conditions or habits may impair osseointegration
Medical conditions like diabetes or habits such as smoking can negatively affect healing and bone integration, impacting the success of the implant.
Which statement best describes the sequence of implant dentistry from start to finish?
- A Implant placed, then abutment attached, then an immediate crown inserted before healing
- B Planning, implant placement, healing, then prosthesis
- C Prosthesis placed, then implant inserted, then the plan created
- D Implant inserted and prosthesis delivered on the same day always
Correct answer: Planning, implant placement, healing, then prosthesis
The standard sequence involves planning, surgical placement of the implant, a healing period for osseointegration, then attaching the abutment and final prosthesis.
What is an implant-retained overdenture and which component often aids its retention?
- A A removable prosthesis anchored on implants, often using ball attachments
- B A fixed bridge unsupported by implants that relies on metal clasps for retention
- C A temporary denture used before implant placement, using suction only
- D A crown on a natural tooth
Correct answer: A removable prosthesis anchored on implants, often using ball attachments
An implant-retained overdenture is a removable denture anchored on implants; ball attachments are commonly used to provide mechanical retention and stability.
Which of the following may be a reason to delay final prosthesis placement after implant surgery?
- A The patient's scheduling availability being the only consideration
- B Insufficient osseointegration or poor bone quality
- C A desire to change the crown shade
- D Normal immediate healing without complications
Correct answer: Insufficient osseointegration or poor bone quality
If osseointegration is incomplete or bone quality is suboptimal, delaying prosthesis placement allows proper healing to ensure long-term implant success.
