The preparation of mouth before the placement of a prosthesis is referred to as pre-prosthetic surgery.
Some patients require minor oral surgical procedures before receiving a partial or complete denture, in order to ensure the maximum level of comfort. A denture sits on the bone ridge, so it is very important that the bone is the proper shape and size. If a tooth needs to be extracted, the underlying bone might be left sharp and uneven. For the best fit of a denture, the bone might need to be smoothed out or reshaped. Occasionally, excess bone would need to be removed prior to denture insertion.
There are types of Pre prosthetic surgeries:
Bone smoothing and reshaping
Removal of excess bone
Bone ridge reduction
Removal of excess gum tissue
Exposure of impacted teeth
