Brief Summary

the aim of the present study was to evaluate the dimensional variation and osseointegration of mini-implants at augmented sinus with the antrostomy left unprotected or protected with a collagen membrane.

Outcome Measures

Primary Outcomes (2)

  • Changing in height of the elevated zone.

    will be assessed in the medial, middle and lateral regions of the elevated zone using the cone beam computerized tomographies

    The CBCTs will be taken before surgery (T0) and 1-week (T1) and 9 months (T2) after surgery

  • Bone-to-implant contact between the different surfaces and between membrane / no membrane groups

    Measurements of new bone formation will be assessed on the histological images taken from the slides and performed between the most coronal bone contact to the surface and the apex of the mini-implant. Comparisons among test and control (without or with a collagen membrane of the access window) and between the two different surface conformations will be performed

    three months of healing

Secondary Outcomes (2)

  • Changing in area of the elevated zone

    The CBCTs will be taken before surgery (T0) and 1-week (T1) and 9 months (T2) after surgery

  • Bone density

    three months of healing

Study Arms (2)

test site

EXPERIMENTAL

The space obtained underneath the sinus mucosa will be filled with the xenograft without protecting the antrostomy with a collagen membrane in the test sites. Bone to implant contact was measured at the turned and machined surface.

Procedure: Maxillary sinus augmentation

control site

ACTIVE COMPARATOR

The space obtained underneath the sinus mucosa will be filled with the xenograft and a resorbable collagen membrane will be placed to cover the antrostomy only at the randomly selected control sites. Bone to implant contact was measured at the turned and machined surface.

Procedure: Maxillary sinus augmentation

Interventions

Surgical technique for increasing the vertical bone height of the posterior maxilla an antrostomy of about 5 mm in height and 10 mm long will be prepared using a diamond insert mounted on a sonic-air surgical instrument. The Schneiderian membrane will be elevated and clinical measurements will be performed using an UNC 15 probe. The space obtained underneath the sinus mucosa will be filled with the xenograft and a resorbable collagen membrane will be placed to cover the antrostomy only at the randomly selected control sites.
