24. A system comprising:
a memory; and
a processing device operatively connected to the memory, the processing device to:

attempt to perform a first registration process that relies upon overlapping features between the intraoral scan data and a first three-dimensional (3D) surface generated from previous intraoral scan data received during the intraoral scan session;
perform a second registration process that does not rely upon overlapping features between the intraoral scan data and the first 3D surface to register the intraoral scan data to the first 3D surface responsive to failure of the attempt to perform the first registration process;
receive additional intraoral scan data; and
repeat the first registration process to register the intraoral scan data and the additional intraoral scan data to the first 3D surface.
