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

Complications (at treated sites) · 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 may leads to higher complications (at treated sites) compared with short implants (5 to 8.5 mm) without sinus augmentation (low certainty).

Surgical anchorage (mini-screw or mid-palatal implant) vs Conventional anchorage (headgear, transpalatal/palatal arch, etc.)

Mesiodistal movement of the upper first permanent molar · Patients of any age undergoing orthodontic treatment with fixed appliances and requiring anchorage (adolescents to adults up to 48-54 years)

Surgical anchorage (mini-screw or mid-palatal implant) probably leads to lower mesiodistal movement of the upper first permanent molar compared with conventional anchorage (headgear, transpalatal/palatal arch, etc.) (moderate certainty).
