Objective: To compare the implant-abutment connection microgap between computer-aided design and computer-aided manufacturing (CAD/CAM) milled or laser-sintered cobalt-chrome custom abutments with or without ceramic veneering and titanium stock abutments with or without crown cementation.
Material And Methods: Six groups of six abutments each were prepared: (1) CAD/CAM cobalt-chrome custom abutments: milled, milled with ceramic veneering, laser-sintered, and laser-sintered with ceramic veneering (four groups: MIL, MIL-C, SIN, and SIN-C, respectively) and (2) titanium stock abutments with or without zirconia crown cementation (two groups: STK and STK-Z, respectively). Abutments were screwed to the implants by applying 30 Ncm torque.
Article Synopsis
- Gradenigo's Syndrome is a rare complication of ear infections, often showing symptoms like double vision and facial pain, but its incidence has dropped due to antibiotic use.
- An elderly patient with T-cell lymphoma exhibited symptoms resembling Gradenigo's, but was ultimately diagnosed with invasive sinus aspergillosis after a challenging diagnostic process.
- The prognosis for cases like this is very poor without surgical intervention, as demonstrated by this patient's death despite antifungal treatment, highlighting the need for doctors to be vigilant, especially in older patients.
