The NOVAMag? membrane is a medical device approved in the EU, and is a completely resorbable and biodegradable metal membrane. This medical device is used in the treatment of bone defects in the oral cavity. The membrane ensures sufficient stability of the bone augmentation material and provides a barrier to the soft tissue. This enables new bone to form in the defect space and for the subsequent placement of dental implants. In this clinical trial, the NOVAMag? membrane is compared with the Jason? collagen membrane, another medical device for supporting bone regeneration, with the aim of demonstrating the non-inferiority in terms of radiographically measured volumetric bone gain of the NOVAMag? membrane to the comparator membrane.

The study aimed to assess 6- and 12-months evaluation of clinical, microbiological, and radiography outcomes after performing peri-implantitis regenerative surgical therapy with the bovine bone substitute with or without hyaluronic acid.
Materials and Methods: The study could be designed as randomized control clinical trial. Patients with a minimum of one or more early, moderate and advanced stages of the peri-implant lesion will be included in the study. After meeting inclusion criteria, during a regenerative surgical procedure, after mucoperiosteal flap elevation and implant surface decontamination, all patients will be randomly divided into two groups: test group in which bovine bone substitute with hyaluronic acid (HA) (Cerabone plus, Botiss, Germany) will be applied for the filling peri-implant bone defects while in the control group peri-implant bone defects will be filled with bovine bone substitute (Cerabone, Botiss, Germany). Bone grafts will be covered in both groups with collagen dermal matrix (Mucoderm, Botiss, Germany). Clinical, radiograph and microbiological outcomes will be followed at 6 and 12 months after the surgical procedure. ISQ implant stability will be measured before, during a surgical procedure, and 7, 15, 30 days, 3, 6 and 12 months after a surgical procedure.

The aim of the present prospective randomized controlled study is to clinically and histologically investigate the safety and efficacy of bony wall repositioning compared to rotary window preparation with membrane coverage in maxillary sinus floor augmentation.
