One-stage augmentation (implants placed simultaneously) vs Two-stage augmentation (delayed implant placement)

Prosthesis failure · Patients with insufficient bone below the maxillary sinus requiring dental implants

One-stage augmentation (implants placed simultaneously) showed no clear difference in prosthesis failure compared with two-stage augmentation (delayed implant placement); GRADE not reported.

Maxillary sinus lift (augmentation) with long implants vs Short implants (5 to 8.5 mm) without sinus augmentation

Prosthesis failure · Patients with missing teeth and an atrophic posterior maxilla, with residual bone height between 4 and 9 mm below the maxillary sinus

Maxillary sinus lift (augmentation) with long implants showed no clear difference in prosthesis failure compared with short implants (5 to 8.5 mm) without sinus augmentation (moderate certainty).

Locking plate vs 2 mm non-locking titanium plates

Post-operative adverse events and complications (paraesthesia, swelling, segmental mobility) · Adults (16 to 68 years) with mandibular fractures excluding condylar involvement
1 finding from 1 review
  • Agarwal 2011: paraesthesia in one participant in the non-locking plate group (resolved by 3 months), none in the locking group; infection rates similar at 6 weeks and 3 months; post-operative swelling in 20% of both…

2 mm titanium plates vs 2.5 mm bioresorbable plates

Post-operative neurosensory disturbance (mental nerve paraesthesia) · Adults (16 to 68 years) with mandibular fractures excluding condylar involvement

2 mm titanium plates led to higher post-operative neurosensory disturbance (mental nerve paraesthesia) compared with 2.5 mm bioresorbable plates; GRADE not reported.

Prophylactic systemic antibiotics (amoxicillin) vs placebo or no antibiotic

Prosthesis failure · Adults undergoing dental implant placement

Prophylactic systemic antibiotics (amoxicillin) showed no clear difference in prosthesis failure compared with no antibiotics or placebo; GRADE not reported.

Autogenous bone graft augmentation at the immediate implant site vs No augmentation

Prosthesis failure · Patients receiving immediate single implants in fresh extraction sockets (maxillary anterior/premolar sites)

Autogenous bone graft augmentation at the immediate implant site led to lower prosthesis failure compared with no augmentation; GRADE not reported.
