The Effectiveness of Internal Maxillary Sinus Elevation Using Controlled Hydrodynamic or Pneumatic Pressure: An Ex-vivo Experimental and Preliminary Animal Study.

Objective The aim of this experimental study was to test the possibility of applying internal sinus elevation techniques using controlled hydrodynamic or pneumatic pressure and evaluate their elevation effectiveness. Materials and methods A device was specially designed for this study and was used to elevate the sinus membrane internally in 12 halves of freshly slaughtered sheep heads. The sample was divided into two groups randomly according to the type of controlled pressure applied (hydrodynamic or pneumatic).
