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

ElementPlanned (methods)Found (results)
PopulationPatients who are having osseointegrated root-form dental implantsEdentulous and partially edentulous jaws, adults only (n=1217 participants, 2120 implants in 26 trials)
Intervention(1) Same implants loaded at different times (immediate/early/conventional); (2) same implants occlusally vs non-occlusally loaded during osseointegration; (3) same implants directly vs progressively loadedImmediate loading; Early loading; Occlusal loading (26 trials; 2120 implants total)
ComparisonConventional loading; Early loading; Immediate loading; Non-occlusal loading; Direct loadingConventional loading; Early loading; Non-occlusal loading
OutcomesProsthesis failure if secondary to implant failure; Implant failures (implant mobility and removal of stable implants dictated by progressive marginal bone loss); Radiographic marginal bone level changes on intraoral radiographs taken with a parallel techniqueProsthesis failure (n=26 trials); Implant failure (n=26 trials); Marginal bone level changes (approx 14 trials)
Study designsRCTs of parallel-group and split-mouth design of root-form osseointegrated dental implants with a follow-up of 4 months to 1 year after loadingRCTs, parallel-group and split-mouth design (26 trials)
TimingFollow-up of 4 months to 1 year after loading1 year (6-9 months data used for Oh 2006 and Cannizzaro 2008d; longer data used for some radiographs)
