  1. The most effective method for decontaminating an implant surface during peri-implantitis surgery is:

    Answer: Mechanical debridement combined with chemical decontamination (saline, citric acid, or chlorhexidine)

    Combining mechanical debridement with chemical surface decontamination reduces the biofilm to levels that allow re-osseointegration or stable healing.

  2. Cement-retained implant complications from excess cement are best prevented by:

    Answer: Using a screw-retained design or placing margins supragingivally for visible cement cleanup

    Placing the crown margin at or above the gum line allows visual confirmation that all cement is removed; alternatively, screw retention eliminates cement-related complications entirely.

  3. Phonetic problems after implant-supported full arch restoration are most commonly due to:

    Answer: Incorrect palatal contour or excessive bulk of the prosthesis affecting tongue space

    Excessive palatal bulk, incorrect tooth position, or inadequate tongue space in full-arch implant prostheses can cause lisping, slurring, or difficulty with sibilant sounds.

  4. Maxillary anterior single implant esthetic failures are most commonly caused by:

    Answer: Labial bone loss and gingival recession exposing the implant or metal collar

    Loss of the thin labial plate of bone leads to gingival recession, exposing the implant shoulder or creating asymmetrical gum levels that compromise esthetics.

  5. Aspiration or swallowing of a dental implant component during prosthetic procedures requires:

    Answer: Immediate patient assessment with appropriate imaging and medical consultation if respiratory compromise

    Aspirated components that enter the airway are a medical emergency requiring immediate chest X-ray and possible bronchoscopy; swallowed components typically pass but must be confirmed.

  6. Implant survival rate at 10 years in healthy patients with proper maintenance is approximately:

    Answer: 90–95%

    Well-documented long-term studies show dental implant 10-year survival rates of 90–95% in healthy patients with regular maintenance, making them a highly predictable treatment.
