From the data that is gathered from the surgical plan, a guided surgery appliance is fabricated based on the specifics of the ideal implant placement.
In addition, a digital scan body (see the above image) can be placed in the plan digitally. This data can then be used to create a custom healing abutment or provisional that will aid in the healing of tissue to an ideal form, allowing for a natural emergence profile. This will maximize function, esthetics, and the overall health of the restoration.
The two additional benefits of guided surgery are:
- A custom healing cap that will shape the tissue and result in an ideal emergence profile.
- An immediate-load temporary designed to provide an ideal emergence profile. These usually come in two parts, including a titanium base and an implant abutment. These should be bonded together intraorally. First, the base is torqued according to the manufacturers’ recommendation, and then the abutment is bonded on.
To do an immediate load, the following conditions must be met:
- The implant chosen for the case must support immediate loading.
- The bone is essential to a successful case and must be evaluated for quality and quantity.
- The implant must be torqued to the recommended NcM.
To create highly esthetic restorations that function naturally, the soft tissue contours must mimic those found in natural teeth. A properly contoured healing abutment can significantly improve the outcome of implant restorations and reduce issues such as food impaction.
