Sinus lift with bone graft (granular Bio-Oss) vs Sinus lift without bone graft (Inion resorbable rigid barrier maintaining space / no bone)

Implant failure · Patients with an atrophic maxillary sinus requiring augmentation (1 to 5 mm residual bone height)

Sinus lift with bone graft (granular Bio-Oss) showed no clear difference in implant failure compared with sinus lift without bone graft (Inion resorbable rigid barrier…; GRADE not reported.

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

Economic factors · Patients of any age undergoing orthodontic treatment with fixed appliances and requiring anchorage (adolescents to adults up to 48-54 years)

The review found no eligible studies for this question.

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).

Hyperbaric oxygen vs No HBO therapy

Prosthetic failure (2 years) · Patients who have had radiotherapy and who have missing teeth that require replacement with osseointegrated dental implants

It is very uncertain whether hyperbaric oxygen (HBO) therapy changes prosthetic failure compared with no HBO therapy (very low certainty).
