Abstract

The modified RPI clasp was described and compared with the conventional RPI clasp in the article. The modified RPI clasp could provide adequate retention with the minimum undercut of the most distal part of abutment tooth and gain good esthetical effect. The I bar tip would disengage from the tooth and reduce or avoid torsional forces transmitted to the abutment tooth when rotation of distal-extension base occurred around the mesio-occlusal rest. Therefore, it is a new type of clasp design for the distal-extension removable partial dentures.

Do patients have a preference for major connector designs?

AIM: The aim of this research was to evaluate patients' preferences for resin analogs of four major connector designs formulated to have equal rigidity once fabricated in the same alloy. METHODS AND MATERIALS: Nineteen Kennedy Class I or II partially edentulous patients participated at two centers. The four major connector analogs (MCAs) were fabricated for each subject using light-polymerizing acrylic resin. The subjects were asked to wear each of them in the mouth for 30 seconds in six pairs in random order, and to report their preference for each pair. Based on these data, the four analogs were ranked in a descending preference order for each patient. Within-subject comparisons preferences were performed with the Friedman test, and the multiple comparisons were performed with the Wilcoxon Signed Ranks test for data of each sample independently. RESULTS: Statistically significant and consistent preference orders were revealed for both samples, and the thin and wide design was significantly preferred to the thick and narrow design. However, a higher variation was observed for the first preference of each subject. CONCLUSIONS: Subjects demonstrated a tendency to prefer thinner MCAs. However, the individual predilections of patients may not be an appropriate basis for an attempt to find a 'best design' applicable to all patients.

[Case report of enterobrosis and diffuse peritonitis caused by a swallowed removable partial denture].

A female patient, aged 62 years, unexpectedly swallowed a removable partial denture (RPD) during the supper. The doctor failed to take out the RPD from her stomach under the gastroscope during the emergency treatment at the first day. 2 days later, the PRD blocked the intestinal tract and its metal clasps penetrated the wall of the intestine near the ileocecal junction, it soon leaded to enterobrosis and diffuse peritonitis. At last, abdominal operation was conducted to take the RPD out from the intestine and enterobrosis was patched up successfully. Diffuse peritonitis was also cured by intravenous infusion of antibiotics for about 1 week.
