MissingSiteDefinition - sharepoint 2007 para 2010

I Migrated Sharepoint 2007 to 2010, but some sites do not open, i run the Test-SPContentDatabasecommand, the MissingSiteDefinition error is displayed for the TemplateId: 75801, 75802, 75803, 75806

 I ran the command: STSADM -o enumallwebs -databasename WSS_Content :

<?xml version="1.0"?>

Why only sites with Templatename = 'Unknown' do not open

Example: if I try to open the URL with TemplateId="75813" the message is displayed:

I try to open the URLs 75801 the message is another: The Webpage can not be found

How can I fix this problem?
