The extraction is the removal of tooth that cannot be saved by any other conservatory method, due to massive coronary destructions or advanced infections or cysts. Extraction may also be needed to remove healthy teeth if the orthodontic treatment requires it.
The root resection is a surgical procedure that removes an untreatable, fractured or dissolving part of the tooth’s root while retaining the original tooth’s structure. Root resection and other endodontic surgical procedures (such as post/core treatment) are done in instances where conventional endodontic (root canal) treatment is not sufficient to save the affected tooth.
When the bone shape does not permit wearing of overdentures or any prosthetic bridge, then bone modeling can be made. This will facilitate painless usage of future prosthetic solutions.
