It is a classical result that a closed exceptional polar set is removable for subharmonic functions which are bounded above. Gardiner has shown that in the case of a compact exceptional set the above boundedness condition can be relaxed by imposing certain smoothness and Hausdorff measure conditions on the set. We give related results for a closed exceptional set, by replacing the smoothness an...

We give an example of a exible curve, i.e., a closed curve ? so that for any other closed curve ? 0 and " > 0 there is a homeomorphism of the sphere, conformal oo ?, so that (?) lies in an " neighborhood of ? 0. Moreover, for any guage function h such that h(t) = o(t) as t ! 0, we may take ? to have zero Hausdorr measure with respect to h. This extends a result of Robert Kaufman on removable se...

Patients who have unusually small mouths may have difficulty in obtaining dental care and maintaining good oral hygiene. The fabrication of conventional complete removable dental prostheses for an edentulous patient with microstomia is challenging because of the limited access to the oral cavity. Sectional collapsible complete removable dental prostheses were designed as hinged maxillary and ma...

An accelerated technique for casting a direct-pattern post and core restoration for use in fixed prosthodontics has been previously described. Similar techniques for use in removable prosthodontics show potential for clinical use, specifically for the fabrication of radicular stud overdenture attachments and their corresponding copings. The procedure uses a chairside technique and readily avail...

BACKGROUND Though implant dentistry is very successful and predictable in treatment of patients with destroyed dentition, there are some cases with limitations to implant therapy. In these cases, alternative treatment modality should be considered. CASE DESCRIPTION A patient with destroyed dentition was rehabilitated with a lateral rotational path removable partial denture. According to the d...

Suppose M is a closed irreducible orientable 3-manifold, K is a knot in M , P and Q are bridge surfaces for K and K is not removable with respect to Q. We show that either Q is equivalent to P or d(K,P ) ≤ 2 − χ(Q − K). If K is not a 2-bridge knot, then the result holds even if K is removable with respect to Q. As a corollary we show that if a knot in S has high distance with respect to some br...

Background and Aim: Different attachment designs have been developed to connect implant to natural teeth in partial dentures; however, adequate studies have not been performed to determine stress distribution patterns in these designs. The present study aimed to assess stress distribution patterns in natural tooth and implant supported removable partial denture with different attachment designs...
