A novel dental implant system with an internal port for endoscopic closed sinus augmentation: a feasibility study in pigs.

Purpose: This study describes the use of an innovative dynamic implant valve approach (DIVA) for dental implant placement and sinus augmentation procedures.

Materials And Methods: The DIVA implant system was tested in vitro for leakage and mechanical fatigue. A closed sinus elevation procedure with a gel-type bone substitute was performed using the DIVA implant in a swine model (n = 6).

Endoscopic intraoral plating of orbital floor fractures.

Purpose: This article describes a new endoscopic approach for orbital floor fractures, reduction, and fixation and reports the clinical results.

Patients And Methods: Ten patients who sustained either a comminuted or trap door orbital floor fracture were treated in 2 medical centers following the same surgical protocol. The indications for orbital reconstruction were limited eye movement, diplopia, and significant enophthalmos.
