Restorative treatment planning is often confounded when periodontal attachment loss, caries or tooth fracture involves the furcation area of the tri-rooted maxillary molars. Although such involvement invariably diminishes the long-term prognosis of the affected teeth, extraction is not always an option. Root resective therapy, which removes the involved root plus its associated crown portion (trisection), is one of several treatment modalities that can be used in such cases. This article reviews the indications and contraindications for root resective therapy, describes the techniques of surgical trisection and presents a case in which combined resective, endodontic and prosthetic management resulted in a successful outcome.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008437	Maxilla	One of a pair of irregularly shaped bones that form the upper jaw. A maxillary bone provides tooth sockets for the superior teeth, forms part of the ORBIT, and contains the MAXILLARY SINUS.	Maxillae,Maxillary Bone,Bone, Maxillary,Bones, Maxillary,Maxillary Bones,Maxillas
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
D003442	Crowns	A prosthetic restoration that reproduces the entire surface anatomy of the visible natural crown of a tooth. It may be partial (covering three or more surfaces of a tooth) or complete (covering all surfaces). It is made of gold or other metal, porcelain, or resin.

D005893	Gingivoplasty	Surgical reshaping of the gingivae and papillae for correction of deformities (particularly enlargements) and to provide the gingivae with a normal and functional form, the incision creating an external bevel. (Dorland, 28th ed)	Gingivoplasties
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000328	Adult	A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available.	Adults
D000543	Alveoloplasty	Conservative contouring of the alveolar process, in preparation for immediate or future denture construction. (Dorland, 28th ed)	Alveoloplasties
D014082	Tooth Fractures	Break or rupture of a tooth or tooth root.	Fracture, Tooth,Fractures, Tooth,Tooth Fracture
D014092	Tooth Root	The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots.
