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 patients who require either preprosthetic surgery with conventional denture construction or construction of an implant retained denture | 60 edentulous patients (Netherlands, University Hospital); a third conventional-denture group in the trial was outside scope and disregarded |
| Intervention | Preprosthetic surgery for a conventional denture | Preprosthetic surgery: interforaminal vestibuloplasty with lowering of the floor of the mouth (n=30) |
| Comparison | Implant retained denture (overdenture) | Implant retained overdenture: two mandibular implants (Branemark or IMZ), clip-retained overdenture (n=30) |
| Outcomes | Morbidity (pain, infection, nerve damage); Patient satisfaction (overall satisfaction, denture retention, appearance, eating, speech; binary and continuous VAS); Cost-effectiveness | Overall denture satisfaction, 0-10 scale (n=60); Overall denture satisfaction, binary (n=58); Dissatisfied with lower denture (n=58); Dissatisfied with appearance (n=58); Dissatisfied with retention (n=58); Dissatisfied with eating (n=58); Dissatisfied with speech (n=58); Morbidity: altered lower lip and chin sensation (n=60); Cost-effectiveness (not extractable) |
| Study designs | Randomised controlled trials | Randomised controlled trial (n=1) |
| Timing | Not specified | 1 year and 5 years follow-up |
