Crown fracture Lack of keratinized tissue Failed osseointegration Loose implant screw Mobility with space indicates screw loosening, not necessarily failure. 13 / 40 Category: Implant 13) What distinguishes one-stage from two-stage implants? Number of surgeries Abutment visibility Healing time All of the above Two-stage implants require a second surgery to expose the fixture. 14 / 40 Category: Implant 14) How to prevent a screwdriver from being ingested during implant placement?

D1 (Dense cortical) D3 (Thin cortical) D2 (Thick cortical) D4 (Trabecular) D2 bone offers optimal density for stability and healing. 16 / 40 Category: Implant 16) What is the interocclusal distance required for cement-retained vs. screw-retained implants? 7 mm for cement, 5 mm screw 3 mm for both 5 mm for both 10 mm for cement, 7 mm screw Screw-retained implants require less vertical space (5 mm) compared to cement-retained (7 mm). 17 / 40 Category: Implant 17) One of two adjacent implants shows bone loss after 3 months. What is the cause? Surgical trauma Occlusal overload Peri-implantitis Poor hygiene Localized bone loss suggests peri-implantitis, not systemic issues. 18 / 40 Category: Implant 18) What is visible in a two-stage implant during healing? Crown Fixture Abutment screw Healing abutment Healing abutments protrude through the gum for soft tissue shaping. 19 / 40 Category: Implant 19) What is the minimum number of implants required for a mandibular overdenture? 1 4 2 3 Two implants provide adequate stability for mandibular overdentures. 20 / 40 Category: Implant 20) What is the required space between a natural tooth and an implant for papilla formation? <8 mm <6 mm <5 mm <7 mm Papilla rarely forms with gaps ≥5 mm. 21 / 40 Category: Implant 21) A picture shows an implant too close to a tooth. What is the likely cause of failure? Proximity to adjacent tooth Poor osseointegration Overloading Peri-implantitis Implants <1.5 mm from teeth risk bone loss and failure. 22 / 40 Category: Implant 22) After extracting upper tooth #6 with slight sinus pneumatization (7 mm space), which procedure is indicated? No lift needed Bone grafting External sinus lift Internal sinus lift Internal lifts are minimally invasive for 4–7 mm bone height. 23 / 40 Category: Implant 23) Which material is recommended for implant impressions? Polyether Alginate PVS Addition silicone Addition silicone offers high accuracy and dimensional stability. 24 / 40 Category: Implant 24) How long should you wait before placing a crown after implant placement? 4 months 6 months 2 months 1 week Maxillary implants need 6 months; mandibular need 3–4 months. 25 / 40 Category: Implant 25) What is the most critical factor in choosing an implant? Periodontal health Patient age Cost Bone density Healthy periodontium ensures long-term implant success. 26 / 40 Category: Implant 26) Radiolucency surrounds an implant at #45 in the image. What should be done? Wait for healing Refer to specialist Augmentation Adjust occlusion Radiolucency indicates failure; removal by a specialist is needed. 27 / 40 Category: Implant 27) Where should an implant be placed relative to the mental foramen? 5 mm anterior 2 mm posterior 2 mm anterior 5 mm posterior Implants must be ≥5 mm anterior to avoid nerve damage. 28 / 40 Category: Implant 28) A patient missing tooth #36 has a 7 mm space between #35 and #37. What implant diameter is suitable? 4 mm 6 mm 5 mm 3 mm 4 mm implants fit 7 mm spaces with proper spacing (1.5 mm per side). 29 / 40 Category: Implant 29) A patient complains of a black line near an upper lateral implant. What is the cause? Gum recession Titanium shadow Labial implant position Poor hygiene Labial positioning causes grayish tissue discoloration. 30 / 40 Category: Implant 30) An implant at #36 shows pus, horizontal bone loss, and mobility. What is the treatment? Remove (failure) Remove and reimplant Antibiotics Bone grafting Purulent discharge and bone loss indicate irreversible failure. 31 / 40 Category: Implant 31) A 5 mm diameter implant in an upper lateral causes inflammation. Why? Oversized implant Poor placement Allergic reaction Infection Anterior implants should be 3–4 mm to avoid soft tissue stress. 32 / 40 Category: Implant 32) A patient has 7 mm between the bone floor and sinuses and requests implants. What is the appropriate procedure? Bone grafting Internal sinus lift External sinus lift Short implants Internal sinus lift is sufficient for 7 mm residual bone height. 33 / 40 Category: Implant 33) For a 7 mm interarch space, what is the optimal treatment?

Cemented implant Hybrid abutment Screw implant with angulated abutment Mini implant Angulated abutments compensate for limited space and improve esthetics. 35 / 40 Category: Implant 35) Which bone type is safest for implant placement? D1 D3 D4 D2 D2 balances density and vascularity, reducing failure risks. 36 / 40 Category: Implant 36) If the intra-arch distance is 10 mm, which type of implant abutment can be placed? Hybrid retained Custom abutment Screw retained Cement retained Cement-retained abutments are preferred for smaller intra-arch distances due to better esthetics. 37 / 40 Category: Implant 37) Which part is used in implant impressions? Crown Coping Analog Screw The analog replicates the implant’s position in the impression. 38 / 40 Category: Implant 38) Which implant is best for a single-tooth crown?
