Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Review question
| Element | Planned (methods) | Found (results) |
|---|---|---|
| Population | Edentulous adult patients requiring complete dentures | Edentulous adults requiring complete dentures (n=30) |
| Intervention | Interventions comparing different posterior occlusal schemes (e.g. anatomic teeth, non-anatomic teeth, zero-degree teeth) in the construction of complete dentures | Lingualised teeth (maxillary anatomic + mandibular non-anatomic; lingualised occlusion) (n=30) |
| Comparison | A different posterior occlusal scheme (head-to-head comparison of schemes) | Zero-degree teeth (non-anatomic, cuspless) (n=30) |
| Outcomes | Patient perceived satisfaction (primary); Patient perceived comfort; Patient perceived masticatory/chewing function; Patient perceived masticatory/chewing efficiency | Patient preference/satisfaction (n=30); Number of adjustments required (n=30) |
| Study designs | Randomised or quasi-randomised controlled clinical trials (RCTs) | 1 cross-over RCT (Clough 1983); judged high risk of bias (insufficient information on randomisation and allocation concealment) |
| Timing | Studies to be grouped according to treatment type and duration of follow up | 3 weeks per denture set (cross-over) |
