Tattoo marking for registration of relapse after oral vestibuloplasty

A simple method for registering extension and relapse after vestibuloplasty based upon tattoo marking has been developed. Tattoo marking with autoclaved India ink was tested on 10 rats and seems to be harmless. This method is considered an alternative to other numerical expressions of extension and relapse after vestibuloplasty, such as radiocephalometrics and analysis of standardized impressions and castings.
