Retentive forces of two magnetic systems compared with two precision attachments.

Magnetic retention devices based on cobalt/samarium alloy are new to dentistry, whereas precision attachments have been used for many years. In this study, the retentive forces of two magnetic systems were compared with two different precision attachment units. The retentive forces were evaluated with an Instron testing machine with a cross-head speed of 0.5 mm/min. Eight samples were used for each of the four attachments for a total of 32 samples. The attachments were embedded in an acrylic block and tested for initial retention and retention after 300 cycles. The retentive forces of the precision attachments were greater than the magnetic attachments for the initial retention. However, as more cycles were completed, the retentive force decreased in the precision attachments and increased in the magnetic attachments. The results were statistically significant among the four attachment systems (p = 0.0117).

[Case report of a patient with bounded missing, treated with removable partial denture].

PATIENT: The patient was a 60-year-old male with the chief complaint of loosening of the bridge on the upper right side. The diagnoses of the patient were detachment of the bridge (7 6 5 4 3 2 1 | 1) and root fracture (5|). A cobalt chromium plate with Mini-SG attachment was used at 4 3 2| to fix the bridge. The course of the patient was uneventful five years after the treatment. DISCUSSION: Judging from the condition of the detached bridge, the same type of fixed bridge was considered too weak to withstand the lateral force. Stabilization of the functional occlusion was achieved by using the attachment, followed by good clinical results. CONCLUSION: The patient was satisfied with the comfort of the removable partial denture with attachment, and good functional results were obtained.

Retention profiles of stud-type precision attachments.

This study measured the retention profiles of 11 commercially available stud-type attachment systems suitable for use with overdentures. The vertical distance over which resistance to separation existed was recorded and related to the configuration of the attachments. In many of the systems tested, only a small portion of the vertical length of the attachment contributed to the retention of the unit.

Stereophotogrammetric analysis of abutment tooth movement in distal-extension removable partial dentures with intracoronal attachments and clasps.

This study applied the three-dimensional measurement technique of stereophotogrammetry to measure abutment tooth movement under occlusal loading as a function of intracoronal attachment and clasp design. Six distal-extension removable partial denture designs were studied: (1) RPI-mesial occlusal rest, proximal plate, buccal I-bar; (2) cast circumferential clasp; (3) P.D. locking semiprecision attachment; (4) Thompson dowel nonlocking semiprecision attachment; (5) McCollum precision attachment; and (6) Stern G/L precision attachment. The movement in microns was determined by computer analysis. The Thompson dowel semiprecision attachment generated the most abutment movement in a gingival direction. The clasp-retained designs generally had less total movement than the attachment designs. Clasps and attachments for the abutment teeth adjacent to the distal-extension bases generally moved more than the abutment teeth.
