Why? Infection Allergic reaction Poor placement Oversized implant Anterior implants should be 3–4 mm to avoid soft tissue stress. 24 / 47 Category: Implant 24) Which dimension most compromises implant success if inadequate? Occlusogingival Bone depth Mesiodistal Horizontal Horizontal width <5 mm risks poor primary stability. 25 / 47 Category: Implant 25) Which bone type is safest for implant placement? D4 D1 D3 D2 D2 balances density and vascularity, reducing failure risks. 26 / 47 Category: Implant 26) If the mesio-distal space is 7 mm, what is the ideal diameter for a single implant? 4 mm 6 mm 5 mm 3 mm A 4 mm implant allows for 1.5 mm clearance on each side (total 7 mm). 27 / 47 Category: Implant 27) What is the most critical factor in choosing an implant? Periodontal health Cost Bone density Patient age Healthy periodontium ensures long-term implant success. 28 / 47 Category: Implant 28) What is the required space between a natural tooth and an implant for papilla formation? <5 mm <8 mm <6 mm <7 mm Papilla rarely forms with gaps ≥5 mm. 29 / 47 Category: Implant 29) For a remaining vertical bone height of 7 mm, which sinus lift method is preferred?
