Pneumatisation of the maxillary sinus is a roadblock to the successful placement of endosseous implants in the posterior maxilla. It is mandatory that the sinus has to be elevated to facilitate implant placement, for which the operating clinician should be well versed with the anatomy of the sinus to avoid intraoperative mishaps. Many techniques of sinus augmentation have been tried and tested with successful outcomes. This article presents a report of a 60-year-old female who had root stumps in relation to upper left first maxillary molar. She wanted an implant to replace the root stumps, however, on cone-beam computed tomography (CBCT) examination the sinus was pneumatised and required augmentation. The root stumps were extracted and after a six-month waiting window, she was treated with an indirect sinus augmentation procedure using Densah™ burs (Jackson, MI: Versah, LLC) after which an implant (5 mm x 8 mm) was placed with good osseointegration at three-month follow-up. The Densah™ bur facilitated sinus lift procedure is a good option for pneumatised sinuses with inadequate residual bone height.

Periodontium is a specialized tissue surrounding the teeth. It is made up of the gingiva, periodontal ligament, cementum, and alveolar bone. The healing of periodontal tissues when infected occurs through repair and regeneration. The central dogma of regenerative periodontics is to stimulate a cascade of healing events that, if coordinated well, can lead to proper tissue synthesis which in turn would play a very important part in managing periodontitis and preventing tooth loss. Many regenerative procedures are being followed in periodontics using newer and modified barrier membranes. Placental membranes like amnion, chorion and amnion-chorion membranes are one among these that serve the purpose because of their active components and therapeutic effects. This literature review highlights the benefits of placental extracts in regenerative periodontal therapy.
