Altered-cast impression technique (ACIP), polyether vs One-piece cast technique (OPC), polyether: Operator-assessed gingival health of abutment
- Population
- Partially edentulous people requiring a tooth- and tissue-supported (distal-extension) removable partial denture
- Intervention
- Altered-cast impression technique (ACIP), polyether
- Comparison
- One-piece cast technique (OPC), polyether
- Outcome
- Operator-assessed gingival health of abutment
It is very uncertain whether altered-cast impression technique (ACIP), polyether changes operator-assessed gingival health of abutment compared with one-piece cast technique (OPC), polyether (very low certainty).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
