Prosthetics: Preprosthetic surgery follows the objective of improving the prosthetic base. Surgical deepening of a flat oral vestibule for example serves to improve the attachment of full dentures. The removal of overlapping bone edges and smoothing of a toothless jaw can also improve the fit of dentures.

Orthodontics: a translocated tooth (usually upper canines) can be surgically exposed and bonded with an attachment element in order to then integrate it into the dental row by orthodontal means. A further surgical indication is given in the case of real diastema (gap between the central incisors with a deep labial frenulum as cause).

Parodontology: Important mucogingival-surgical procedures are, for example:

• Fren(ul)ectomy, fren(ul)otomy or frenuloplastic: practised to sever or displace the labial, buccal and tongue frenulum
• Vestibulo- or oral vestibuloplasties
• Free mucosal transplants and sliding flap for plastic coverage of parodontal recessions.
