Efficacy of demineralized bone matrix for maxillary sinus lift with implant retained prosthetic rehabilitation: A prospective evaluation

Context: Several materials have been used for maxillary sinus augmentation for subsequent implant-supported prosthetic rehabilitation. No perfect material has been identified for the purpose. Aims: The aim of the study is to clinically and radiographically evaluate the use of Sterile Demineralized bone matrix (Osseograft™) for maxillary sinus augmentation and subsequent implant-supported prosthetic rehabilitation. Subject and Methods: Sinus augmentation and implant placement were carried out in 20 patients with Osseograft™. Using intraoral periapical radiographs, radiographic implant length (rIL), residual bone height at the mesial (mRBH) and distal (dRBH) aspects of the implant, Height of the graft apically (aGH) were measured. Residual bone height (RBH) =Mean of mRBH and dRBH, implant penetration (IP) = difference between rIL and RBH, the extent of the sinus lift (SL) = sum of IP and aGH were calculated and a qualitative assessment of maturation was performed using the Sinus Grafting Remodeling Index (SGRI). Statistical Analysis Used: Descriptive statistics. Results: The mean RBH immediately after surgery was 6.81 mm. The mean IP length was 5.45 mm. The mean aGH was 3.21 mm. The mean Extent of the SL was 8.89 mm. At 3 months and 06 months, the mean aGH was 2.68 mm and 2.57 mm. The mean SL at 3 months and 06 months was 7.84 mm and 7.73 mm. The SGRI was 1 in all cases immediately postsurgery; between 1 and 2 at the end of 3 months; 2 in 15 cases and 1 in 4 cases at the end of 6 months. Conclusions: Osseograft™ can be used as an effective material for sinus augmentation with minimal complications and morbidity to the patient.
