@Car 54 Your last sentence is the heart of it.
Bone reduction goes against most everything we have been taught about the importance of bone and it's conservation.
I/we try to avoid significant reduction of bone since in most cases we fight so hard to keep it or restore it with varied rates of success.
At times it is necessary for the better longevity of the implants and restoration and other times it is necessary for aesthetic reasons if the
transition between the prosthetic and what is left of the maxillary alveolar process will be visible in the aesthetic zone.
Competent technicians with long experience in restoring full arch/mouth restorations are more than qualified to determine what is "aesthetic"
and where bone reduction would be beneficial regarding aesthetics. It is most certainly up to the clinicians and ultimately the surgeon if this
solution is viable and in the best interest of the patient in their specific situation anatomically speaking.
Collaboration between all participants in the process of restoring a patient is important. Each bringing a different set of special skills and
experience to the table. Team work is in the best interest of the patient. We as technician's are not planning the bone reduction, but merely
suggesting where it would work best from our experiences fabricating prosthetics. Just more data for the clinician/surgeon to use in determining
what is the best method for a specific situation.
