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.

PopulationPatients with missing teeth who may require horizontal and/or vertical alveolar bone augmentation prior to or during dental implant placement procedures224 patients in 13 trials; 3 RCTs (106 patients) horizontal and 10 trials (218 patients) vertical augmentation; 9 parallel-group and 4 split-mouth; 8 in Italy and 5 in the Netherlands
InterventionAny horizontal or vertical bone augmentation technique, active agent (e.g. bone morphogenetic proteins, platelet-rich plasma) or biomaterials used with osseointegrated root-formed dental implantsInlay/interposed graft + longer implants (n=50 across 2 trials); autogenous bone block from chin (n=31/31); sinus + buccal onlay grafts with PRP (n=5); buccal onlay grafts, titanium screws (n=8); vertical distraction osteogenesis (n=11/9/5); vertical GBR autogenous bone (n=5); GBR non-resorbable barrier (n=11); inlay autogenous bone (n=10); ultrasound during distraction (n=5); autogenous inlay graft (n=10)
ComparisonDifferent bone augmentation techniques; No augmentation; Barrier membraneShort implants (n=48 across 2 trials); 100% Bio-Oss + resorbable barrier (n=31); grafts without PRP (n=5); resorbable screws (n=8); autogenous inlay/onlay bone graft (n=6/8/13); GBR / bone substitute; resorbable barriers + osteosynthesis plates (n=11); placebo ultrasound (n=4)
OutcomesProsthesis failure; Implant failure; Augmentation procedure failure; Major complications at augmented sites; Major complications at bone donor sites; Patient satisfaction including aesthetics; Patient preference including aesthetics; Bone gain vertically or horizontally or both; Aesthetics evaluated by dentist; Duration of the treatment time; Treatment costs; Bone level changes over timeProsthesis failure (n=224); Implant failure (n=224); Augmentation procedure failure; Major complications at augmented/donor sites; Patient satisfaction/preference (n=40); Bone gain vertically/horizontally; Perimplant bone level changes; Aesthetics by dentist (n=31); Treatment time
Study designsRandomised controlled clinical trials including split-mouth studiesAll 13 included studies were RCTs (9 parallel-group, 4 split-mouth) at university, hospital or specialist clinics and 2 in private practice
TimingAbutment connection, 1, 3 and 5 years after loadingFollow-up ranged from 4 months post-loading to 3 years post-loading: 4 months (1 trial), 1 year (4), 1.5 years (1), 2 years (4), 3 years (3)
