However, the first and the foremost requirement for the placement of an implant is the presence of an adequate alveolar bone. By adequate bone, is meant that both the quality and the quantity of the bone have to be sufficient for implant placement. Posterior maxilla often presents with insufficiently available bone for the placement of implants due to the presence of antrum of hymore most commonly known as the maxillary sinus. This jeopardises the successful implementation of implant dentistry in such situations. The present article is aimed at throwing some light on how to deal with the problem of resorbed ridges and a pneumatised sinus through the process of sinus lift and PRF placement in order to facilitate implant placement. Key words: Sinus lift, PRF, implant placement. INTRODUCTION An adequate quality and quantity of bone is essential for successful implant placement. Posterior maxilla presents several challenges to an implantologist that is unique to this region. [1] Most important of these is the presence of a maxillary sinus. Lining mucosa of the maxillary sinus is the Schenedrian membrane. The structures that lie beneath the sinus are the alveloar bone and the posterior teeth. As the edentulous span continues to atrophy, there is continuous loss of bone height and density and pneumatisation of sinus. When implant is inserted in this area, the initial implant stability is poor coupled with inadequate bone height for the implant length. This results in implant failure either initially or during loading. The procedure of choice to restore this anatomic deficiency is the maxillary sinus lift. SINUS LIFT Sinus Lift is a procedure in which the maxillary sinus membrane is elevated and subantral augmentation is performed with bone graft placement. [2] The end result being an improved bone height in the posterior maxilla which is more favourable for implant placement. Two approaches: 1. The direct approach 2. The indirect approach
