Maxillary Sinus Floor Elevation With Gelatin Sponge Versus Allogenic Demineralized Bone Matrix

Beni-Suef University

Details and patient eligibility

About

The post-extraction pneumatization of the maxillary sinus often compromises the ability of the maxillary molar to the optimal recipient of dental implants as a consequence of the quantitative reduction of the vertical bone height and the reduced bone quality of the region posterior maxillary segment.

Enrollment: 14 patients

Sex: All

Ages: 25 to 55 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Patients of both sexes, with an age range of (25 to 55 years) with unilateral or bilateral edentulous posterior maxillary molar region with \ vertical residual bone height of (four to six millimeters), a minimal horizontal bone width of six millimeters bone width, acceptable interarch space, and fair inter-jaw anteroposterior, horizontal and vertical relationships.
2. Proper general health and oral hygiene.

Exclusion criteria

1. The presence of sinusitis, local sinus pathosis, or a systemic disease that would affect the final treatment outcomes, bone remodeling process, or maxillary sinus health.
2. Those patients with a history of previous bone graft, sinus lift, or failed implant.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Crossover Assignment

Masking: None (Open label)

14 participants in 2 patient groups

Test group: Gelatin Sponge

Active Comparator group

Description:

The surgical intervention will be executed under local anesthesia. After the elevation of the full-thickness mucoperiosteal flap over the lateral wall of the maxillary sinus, a circular lateral window will be created by sinus low-speed bur grinding of the cortical ring to guard against the Shniederian membrane violation, followed by its separation along the sinus floor, lateral walls and the boundaries of the window to elaborate a smooth superior membrane elevation. The created spaces beneath the elevated Shniederian membrane will be filled up by an absorbable gelatin sponge for the test group patients followed by the coverage of the side window with collagen membrane, secured with bone tacks to guard against the graft fibroblastic invasion.

Treatment:

Procedure: Sinus lifting

Control group: Allogenic Demineralized Bone Matrix

Active Comparator group

The created spaces beneath the elevated Shniederian membrane will be filled up by allogenic (DBM) for the control group patients, followed by the coverage of the side window with collagen membrane, secured with bone tacks to guard against the graft fibroblastic invasion.
