Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Schneiderian mucosa will be elevated and the created space will be filled with a natural bovine bone grafting material (Cerabone® 1-2 mm, Botiss Biomaterials GmbH). In ten patients randomly selected (control sties), a native collagen membrane made of porcine dermis (Collprotect®, Botiss Biomaterials GmbH) will be placed on the antrostomy. In another ten patients of the test group, the antrostomy will be left without the membrane. The flaps will be sutured and anti-inflammatory drugs and antibiotics will be administrated to the patients. The sutures will be removed after 7 days. After 6 months of healing, two mini-implants with different surface will be installed and retrieved after further 3 months for histomorphometric evaluations.

CBCTs will be taken for all patients before surgery (T0), after 1 week from sinus floor augmentation (T1) and after 9 months of healing (T2) and evaluation of dimensional variations over time of soft and hard tissues will be performed.

test site

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.

Group Type EXPERIMENTAL

Maxillary sinus augmentation

Intervention Type PROCEDURE

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.

control site

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.
