Modified lingual split technique for extraction of impacted mandibular third molars. 1980

J E Lewis

Critical evaluation of existing chisel and bur techniques for removal of impacted mandibular third molars reveals a high incidence of complications. Both approaches require creation of a buccal defect immediately distal to the second molar for the insertion of an elevator, which may cause pocketing to occur postoperatively. The method described here minimizes periosteal reflection, almost completely avoids loss of bone, and effectively reduces the use of rotary instrumentation. The planning of the soft tissue flaps and bony cuts assists in primary wound closure, obliteration of dead space, and reduction of postoperative morbidity.

UI	MeSH Term	Description	Entries
D008963	Molar	The most posterior teeth on either side of the jaw, totaling eight in the deciduous dentition (2 on each side, upper and lower), and usually 12 in the permanent dentition (three on each side, upper and lower). They are grinding teeth, having large crowns and broad chewing surfaces. (Jablonski, Dictionary of Dentistry, 1992, p821)	Molars
D010521	Periosteum	Thin outer membrane that surrounds a bone. It contains CONNECTIVE TISSUE, CAPILLARIES, nerves, and a number of cell types.
D005881	Gingiva	Oral tissue surrounding and attached to TEETH.	Gums,Interdental Papilla,Papilla, Interdental,Gum
D005890	Gingivectomy	Surgical excision of the gingiva at the level of its attachment, thus creating new marginal gingiva. This procedure is used to eliminate gingival or periodontal pockets or to provide an approach for extensive surgical interventions, and to gain access necessary to remove calculus within the pocket.

D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000541	Alveolectomy	Subtotal or complete excision of the alveolar process of the maxilla or mandible. (Dorland, 28th ed)	Alveolectomies
D014081	Tooth Extraction	The surgical removal of a tooth. (Dorland, 28th ed)	Extraction, Tooth,Extractions, Tooth,Tooth Extractions
D014095	Tooth, Impacted	A tooth that is prevented from erupting by a physical barrier, usually other teeth. Impaction may also result from orientation of the tooth in an other than vertical position in the periodontal structures.	Teeth, Impacted,Impacted Teeth,Impacted Tooth
D061221	Trigeminal Nerve Injuries	Traumatic injuries to the TRIGEMINAL NERVE. It may result in extreme pain, abnormal sensation in the areas the nerve innervates on face, jaw, gums and tongue and can cause difficulties with speech and chewing. It is sometimes associated with various dental treatments.
