Surgical template impression during stage I surgery for fabrication of a provisional restoration to be placed at stage II surgery.
The fixture impression method presented permits the construction of a master cast after stage I surgery, enabling the dentist and dental technician to make a provisional crown before stage II surgery. At stage II surgery the surgeon can place the provisional crown instead of a classic abutment or healing cylinder. This eliminates the need for the patient to visit the restorative dentist immediately after stage II surgery for the making of a provisional crown, which can be a scheduling and logistic problem. In addition, better soft tissue contour is possible at stage II surgery, as the premade provisional crown can be shaped to the desired dimensions in the laboratory for ideal esthetics. The soft tissue will adapt to the predetermined surface dimensions during initial healing. Ideal soft tissue contours are present and stable when the final impression is made, which enables better esthetics to be developed for the permanent fixture-retained single-tooth restoration.
