Methods Twenty mandibular distal-extension cases were enrolled in this study to measure the masticatory efficiency after repair with attachment dentures and clasp removable partial dentures for one month.
Method s The s keletal and dental changes before and after the surgery were analysed by cephal ometrics,The factors that might be responsible for the skeletal relapse were evaluated using multiple linear and partial correlation analysis.
We also compute the Euler characteristic of the space of partial flags containingnt and give a connection with hyperplane arrangements.
Then theG0-orbit structure ofZ is described explicitly by the partial Cayley transforms of a certain hermitian symmetric sub-flagF?Z.
Semi-invariants of quivers can be constructed by taking admissible partial polarizations of the determinant of matrices containing sums of matrix components of the representation and the identity matrix as blocks.
We define a partial order on the set No,c of pairs (O,C), where O is a nilpotent orbit and C is a conjugacy class in A(O), Lusztig's canonical quotient of A(O).
We also give formulas for intersection pairings on resolutions of singularities (or more precisely partial resolutions, since orbifold singularities are allowed) of the quotients.
