Normal 0 false false false EN-US X-NONE AR-SA Treating bony craters by surgical method needs elimination or reduction of bony lesions as well as providing sufficient bone by minimum osteotomy in order to preserve supporting bone. Furcation preservation is very important. Most mandibular molars are overtreated from buccal aspect that leads to inverted morphology and affects buccal forcation. Identifying anatomical structures and their relation to lesions is essential. In crater therapy, furcation and tooth trunk are two major anatomical structures. Low to medium Craters are appropriate for osseous resection. Craters of maxillary molars with palatal plate bone loss are treated by 10 degree palatal inclination and decreasing buccal bone according to root trunk. Besides, osteoplasty  is indicated for buccal bone. Second molars are treated similarly but they have longer root trunks and thicker buccal bone which needs osteoplasty. Craters of Mandibular first molar area are treated by osteoplasty in lingual bone as well as buccal bone reduction according to root trunk . likewise, second molars are treated but they have more lingual bone as well as lingual inclination of teeth and longer root trunks.  On the other hand, scalloped morphology is not sufficiently favorable. Therefore, in order to change flat or low scalloped   morphology we should not destroy supporting bone.
