Osseodensification has been a subject of interest in the research arena. It employs densah bur, with negative rake angle and counterclockwise motion, to perform nonsubtractive drilling. In the presence of copious irrigation, it can push the bone trabeculae into the osteotomy instead of leaving it. This compaction can increase bone density, bone volume and subsequently enhance implant stability. The aim of this study is to report a case using densah bur successfully for osseous densification and crestal maxillary sinus augmentation. Further clinical trials are required to validate these findings and confirm whether it can be used for ridge expansion.

Prosthetic treatment of patients with severe wear is challenging task. First step is controlling the causative factor that led to teeth wear along with the restoration of lost dentition. This case report describes the full mouth rehabilitation of a patient with severe attrition. Facebow and centric relation records were used to mount maxillary and mandibular models respectively. Over-erupted teeth beyond the occlusal plane of the mounted models were extracted. Diagnostic waxing-up guided by digital smile design was used in treatment planning, based on which silicone keys were constructed. Direct composite resin was used to rebuild the teeth, using silicone keys, for both vertical dimension increase and interim restorative phases. Composite restorations guided by digital smile design can serve as an excellent tool for vertical dimension increase when compared to removable occlusal splint in terms of better patients' adaptation, esthetics and masticatory performance.
