Connective tissue and dermal grafts are routinely used in the management of gingival recession in the natural dentition. These techniques are pivotal in implant surgery to enhance tissue volume and improve post-restoration tissue levels.

provisionalization 7

make knowledge functional

Provisionalization can be viewed as the fine-tuning of tissue architecture around implants and in adjacent pontic sites. It is an essential step in the restoration of implants in the esthetic zone and is a pivotal step in the transfer of information from the restorative team to the technician.
