The maxilla is a paired bone that forms a significant portion of the midface. It articulates with the frontal, zygomatic, palatine bone, and sphenoid bones. The Le Fort I segment, the portion of the maxilla mobilized during the osteotomy, receives its blood supply primarily from the ascending palatine artery (a branch of the facial artery) and the anterior branch of the ascending pharyngeal ...
Mandibular setback surgery is a surgical procedure performed along the occlusal plane to prevent bite opening on the anterior or posterior teeth and retract the lower jaw for both functional and aesthetic effects in patients with mandibular prognathism. [1] [2] It is an orthodontic surgery that is a form of reconstructive plastic surgery. [3]
The GBR principle was first examined by Dahlin et al. in 1988 on rats. The selective ingrowth of bone-forming cells into a bone defect region could be improved if the adjacent tissue is kept away with a membrane; this was confirmed in a study by Kostopoulos and Karring in 1994. GBR can be used for bone regeneration on exposed implant coils . [4]
A comparison of the outcome of periradicular surgery in teeth that had previously undergone surgical treatment versus teeth that were undergoing a surgical procedure for the first time showed that, after 5 years, 86% of surgically treated teeth healed with complete bone filling of the surgical cavity while only 59% of resurgically treated teeth ...
Crown lengthening is a technique for increasing crown height of teeth by flap surgery with or without bone surgery. [3] There are two main types: Aesthetic crown lengthening which is performed when a "gummy" smile is an issue for the patient [3] Functional crown lengthening is used to make an unrestorable tooth restorable.
Surgical extractions almost always require an incision. In a surgical extraction the dentist may elevate the soft tissues covering the tooth and bone, and may also remove some of the overlying and/or surrounding jaw bone with a drill or, less commonly, an instrument called an osteotome. Frequently, the tooth may be split into multiple pieces to ...
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months.

Periradicular surgery has a risk of complications, which can be minimised by the surgeon. By identifying and managing any complications, long-term damage is usually prevented. Pain and swelling are common, and can be managed with prescription analgesics. A long-acting local anaesthetic may provide relief immediately after surgery. [14]
