Which technique is used to evaluate the volumetric stability of soft tissue grafts used for peri-implant tissue augmentation?
Answer: Superimposition of intraoral scans at baseline and follow-up
Superimposing serial intraoral scans allows three-dimensional volumetric assessment of soft tissue graft changes over time.
Screw-retained implant restorations are preferred over cement-retained restorations primarily because they:
Answer: Eliminate the risk of residual cement causing peri-implant disease
Screw-retained restorations eliminate subgingival cement, a major risk factor for peri-implantitis, and allow retrievability for maintenance.
The Summers osteotome sinus floor elevation technique relies on which principle to elevate the sinus membrane?
Answer: Controlled infracture of the sinus floor bone using blunt instruments
The Summers technique uses sequentially larger osteotomes to condense and infracture the sinus floor, elevating the membrane via the crestal approach.
A patient presents with implant mobility 18 months after placement. The most appropriate initial management is:
Answer: Remove the implant immediately
Mobility indicates complete failure of osseointegration; a mobile implant cannot be stabilized through conservative measures and must be removed.
According to the 2017 World Workshop classification, peri-implant mucositis is characterized by:
Answer: Bleeding on probing without radiographic bone loss
Peri-implant mucositis is defined by bleeding on probing (and/or suppuration) with increased probing depths compared to baseline, but without radiographic bone loss.
Which of the following systemic conditions is considered an ABSOLUTE contraindication to implant placement?
Answer: Recent myocardial infarction (within 6 months) with ongoing anticoagulation
Recent myocardial infarction with active anticoagulation is an absolute contraindication due to unacceptable surgical hemorrhagic risk and compromised healing.
The socket shield technique (partial root retention) in immediate implant placement is designed to preserve:
Answer: The buccal bundle bone by maintaining the root's PDL support
Retaining the buccal root fragment preserves its PDL blood supply to the bundle bone, preventing resorption of the thin buccal plate after extraction.
