| Abstract | PURPOSE: The purpose of the present retrospective investigation was to evaluate the survivability and success of single implants placed simultaneously during direct sinus lifts with allograft forms of bone and to investigate the effect demineralized bone matrix paste has on time management and membrane integrity during these procedures. MATERIALS AND METHODS: The charts of 49 consecutively treated nonsmoking patients who had met the inclusion criteria were examined. All the patients had undergone unilateral direct sinus augmentation using the lateral window technique, during which only 1 implant (minimum 10 mm in length) was placed in the premolar or molar maxillary region. All implants were submerged using a 2-stage technique and with at least 3 mm of residual sinus floor bone height. The control group of 27 patients had received particulate allograft bone as the graft material, and the 22 test patients had received allograft bone in a paste form (DynaBlast). No implants were loaded before a minimum of 6 months from the date of fixture placement. All implant-supported single crowns in the present study had been functioning for at least 12 months. All patients were seen immediately after placement of the final crown and were requested to return to the surgeon's practice for 1 annual radiographic follow-up examination. The range of follow-up for these patients was 12 to 24 months based entirely on patient compliance. This interval constituted the loading time. The patients were not seen by the specialist in between the 'final crown' appointment (original radiograph) and the 'annual' follow-up evaluation (final radiograph). No patients experienced complications that required surgical re-entry. The average loading time for the control group was 13.62 months and was 18.77 months for the test group. The survivability and success of the implants were studied, along with the operative time, between the 2 groups. Statistical analysis was performed for various comparisons in the present study. RESULTS: None of the fixtures placed in these patients failed. The success and survivability criteria as stated were met for all 49 implants, regardless of the allograft formulation used. The average operative time in the control group was 70.11 minutes and was 62.36 minutes in the test group. This difference was statistically significant (P < .05). CONCLUSIONS: Using an injectable formulation of allograft material during simultaneous direct sinus lift and implant placement seems to be an acceptable alternative to particulate forms of allograft bone. In addition, when using the injectable graft evaluated in our study, a statistically significant 11% decrease in the operative time resulted. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
