Provisional restorations serve so many important functions. They can make or break any treatment, but especially a comprehensive fixed reconstruction.
1. They serve as a cosmetic blueprint that can be modified or approved by the patient and transferred to the lab via study cast or digital scan.
2. They serve as the occlusal blueprint that can be modified or approved by the patient and dentist and transferred to the lab via study cast or digital scan.
3. They should keep the tissue happy and healthy during treatment.
4. They give the patient confidence in themselves and YOU during treatment. More times than I can remember, I have seen patients seeking second opinions during treatment because they are in misery with their poorly made and maintained provisionals.
Why do we do a 4 week reline after periodontal corrective surgery? Why do we temporize at all?
Temporizing a patient prior to periodontal corrective procedures allows 3 things:
1. Determine the apical extent of the caries so that the correct biologic width can be established with out guessing where the future margin will be. If we know where the margin will be established, we will know exactly where to create the osseous architecture in establishing the biologic width.
2. It allows us to determine the prognosis of the tooth BEFORE a patient goes through additional procedures such as crown lengthening. All too often, I have seen cases that wasted a patients time, discomfort and money because an endodontic or periodontal procedure was performed before the prognosis of the tooth was determined and the tooth would up being removed in favor of an implant.
