the present report describes orthodontic treatment of a patient with skeletal class iii malocclusion and maxillary hypoplasia. to correct the retrusive maxilla, the treatment plan included an intra-oral removable device. it had the advantages of good patient cooperation, ease of construction and effective modification. forward growth of the maxilla, minimal downward and backward rotation of the...

background and aims. the first few days following the insertion of complete dentures are critical for the patients since they are struggling to adapt to their new dentures. this study aimed to evaluate the most common locations of traumatic ulcerations, their frequency and also the duration and number of adjustment visits required to achieve patient comfort following placement of complete dentu...

For a brick apart from a few small graphs, Lovász (1987) proposed a conjecture on the existence of an edge whose deletion results in a graph with only one brick in its tight cut decomposition. Carvalho, Lucchesi, and Murty (2002) confirmed this conjecture by showing the existence of such two edges. This paper generalizes the result obtained by Carvalho et al. to the case of irreducible near-bri...

Abstract. Let x0 ∈ Ω ⊂ R, n ≥ 2, be a domain and let m ≥ 2. We will prove that a solution u of the polyharmonic equation ∆u = 0 in Ω \ {x0} has a removable singularity at x0 if and only if |∆u(x)| = o(|x − x0|) ∀k = 0, 1, 2, . . . , m − 1 as |x − x0| → 0 for n ≥ 3 and = o(log(|x−x0|)) ∀k = 0, 1, 2, . . . , m− 1 as |x−x0| → 0 for n = 2. For m ≥ 2 we will also prove that u has a removable singula...

BACKGROUND AND AIM: Since increasing the proportion of elderly in the world, so oral lesions related to removable denture-wearing are an important issue. The aim of this study was to evaluate the prevalence of denture-related oral mucosal lesions (DMLs) in removable denture wearers referred to clinics of Kerman, Iran.METHODS: This cross-sectional study was conducted on 350 removable denture wea...
