Abstract: Patients provided with 24 ball attachment-retained removable partial dentures were followed up to 23.5 years. The prosthetic treatment included fixed partial dentures in 8 arches, and combinations of crowns and splint bars in 16 arches. All ball attachment matrices were supplied with vertical occlusal stops in contact with the patrices. A nonresilient hinged coupling was established between fixed partial dentures and removable partial dentures. Seventeen arches had only two or three remaining teeth. A total of 66 abutments for fixed partial dentures were included, 30 of which were root canal treated and supplied with posts. No technical failures (loss of retention/cement failure, root or tooth fracture, metal framework fracture) with the fixed partial dentures were recorded. With the removable partial dentures, additional retention with clasps was introduced in 2 of the dentures (in addition to 8 originally), 2 had to be remade after fractures, and 4 dentures were relined.

TL;DR: Fictional attachments with lamellae for activation are to be preferred for use in matrices and patrices over attachments having spring-loaded retention.

A retrospective study of combined fixed–removable reconstructions with their analysis of failures
TL;DR: The survival rate and the reasons for failures of 130 combined fixed-removable reconstructions (CFR), incorporated in 112 patients, were assessed and the anatomy of the partially edentulous tooth arch in form of the free-end situation and the dentate opposing jaw were identified as risk factors.

TL;DR: The purpose of this article is to provide an overview and a simplified approach to this treatment modality by way of a case report.
Evaluation of the retentive characteristics of semi-precision extracoronal attachments
TL;DR: Results suggest that the inaccuracies of casting and laboratory procedure have only limited influence on the fit of the semi-precision attachments.

The Impact of Removable Partial Dentures on the Health of Oral Tissues: A Systematic Review
TL;DR: There were insufficient RCTs to adequately address the original research question, suggesting that in the absence of good oral hygiene measures a RPD may promote accumulation of the plaque which may in turn lead to gingival inflammation.

TL;DR: During 1985 and 1986, 25 patients were treated with conical crown retained dentures, 26 in the maxillary arch and four in the mandible, and clinical findings after 24 to 43 months are reported and considered promising.

TL;DR: Eleven patients who had only two remaining natural teeth, vital mandibular canines, were treated using experimental 12-unit fixed partial dentures and complete maxillary dentures, finding the periodontal tissues withstood the increased stress, and the prostheses were stable.
