We define a statistic, called weight, on involutions and consider two applications in which this statistic arises. Let I (n)denote the set of all involutions on [n](= {1, 2, . . . , n}) and let F(2n)denote the set of all fixed point free involutions on [2n]. For an involution δ, let |δ| denote the number of 2-cycles in δ. Let [n]q = 1+q+· · ·+qn−1 and let(More)
The de Bruijn–Tengbergen–Kruyswijk (BTK) construction is a simple algorithm that produces an explicit symmetric chain decomposition of a product of chains. We linearize the BTK algorithm and show that it produces an explicit symmetric Jordan basis (SJB). In the special case of a Boolean algebra, the resulting SJB is orthogonal with respect to the standard(More)
OBJECTIVE The aim of this review was to test the hypothesis that 6 mm micro-rough short Straumann(®) implants provide predictable survival rates and verify that most failures occurring are early failures. MATERIALS AND METHODS A PubMed and hand search was performed to identify studies involving micro-rough 6-mm-short implants published between January(More)
PURPOSE This review of literature was conducted to evaluate the predictability of treatment outcomes with short dental implants (SDI), ie, implants shorter than 8 mm. MATERIALS AND METHODS The review included studies, published between January 1990 and July 2011, that (1) involved SDI (<8 mm) placed in human jaws, (2) had a minimum of 20 SDI in their(More)
PURPOSE High survival rates have frequently been reported for immediately loaded implants. The aim of this systematic review was to compare immediately loaded with early and conventional loaded implants for overdenture treatment with regard to their 1-year survival rates. MATERIALS AND METHODS Systematic database (Medline, Embase, CENTRAL) and hand(More)
BACKGROUND Mandibular two-implant-retained overdentures were suggested as first choice of treatment for edentulous mandibles. However, wear of the attachments may reduce their retention and compromise long-term clinical success. AIM The aim of this in vitro study was to compare the change in the retentive force and removal torque of three attachment(More)
Peled, U.N. and M.K. Srinivasan. Poset matching-a distributive analog of independent matching, Discrete Mathematics 114 (1993) 403-424. Given poset matroids (or distributive supermatroids) on two finite posets and an ordered binary relation which associates with every element of each poset an (order) ideal of other poset, a poset matching matches(More)
OBJECTIVE This in vitro study evaluated the influence of implant angulations on the retentive behavior of two overdenture attachments during cyclic dislodging. METHODS Models simulating a two-implant overdenture situation were fabricated. They were divided into five groups based on their simulated implant angulations (Groups: 1 = 0°; 2 = 20°; 3 = 30°; 4 =(More)
OBJECTIVE This systematic review was conducted to evaluate the outcome of dental implant therapy in elderly patients (≥65 years). MATERIAL AND METHODS Online database and hand searches were systematically performed to identify studies reporting on dental implants placed in the partially/completely edentulous jaws of elderly patients. Only prospective(More)
