Cairo University (CU)

Status: Unknown

Conditions: Maxillary Sinus Floor Elevation

Study type: Interventional

Funder types: Other

Identifiers

Details and patient eligibility

About

30 recruited patients indicated for sinus membrane elevation with simultaneous implant placement. patients are divided into 2 groups each group contain 15 patients, one group assigned for placement of bovine bone graft after membrane elevation and insertion of the implants while the other group assigned for graft-less tenting technique after membrane elevation and insertion of the implant.

Full description

On the 2 groups a mucoperiosteal flap is elvated then a lateral wondow is created then sinus membrane is elevated then the implants are placed, in the control group deproteinized bovine bone graft substitute is placed in the sinus for augmentation while in the study group no bone graft is added inside the sinus( graftless tenting technique)

Enrollment: 30 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• patients with atrophic maxilla and pneumatization of the maxillary sinus with residual bone height at least 5mm as per MISCH criteria.
• both sexes.

Exclusion criteria

• sinus pathology
• heavy smokers(more than 20 cigarettes per day.
• patients with systemic disease that may affect normal healing.
