When repairing tooth defects, the teeth need to be ground and trimmed, and then the full crown, inlay, veneer and other restorations are made through impression making, and then bonded to the affected teeth to restore the normal tooth shape and function. When repairing missing teeth, implant restoration is often used. The implant is implanted into the alveolar bone of the toothless part. When the bone condition is poor, bone powder filling operation is required. When the implant forms bone fusion with the alveolar bone, the repair base and all-ceramic crown are installed on the upper part of the implant with screws. This is a method of repairing missing teeth that uses the lower structure implanted in the bone tissue as a basis to support and retain the upper dental restoration.
