Characterization of the binding of delmopinol to salivary precipitates.
The aim of this study was to quantify the amount of delmopinol recovered in different molecular weight ranges of salivary proteins in the supernatant and pellet of delmopinol-saliva mixes. Unstimulated whole saliva was collected from 5 subjects and mixed with radiolabeled delmopinol to obtain a final drug concentration of 9.7 mM. The salivary-delmopinol solutions were incubated and then centrifuged. The resulting pellets and supernatants were studied in an electrophoresis assay. Each individual sample was run in three different electrophoretic gel lanes. The first lane was stained with silver dyes; the second lane was used for electrophoretic blotting and autoradiography; the third lane was cut in standard slices that were dissolved and analyzed with scintillation counting. The scintillation results demonstrated that higher radioactivity levels were detected at high molecular weight ranges (700-600 kDa). Furthermore, pellet samples were found to contain the highest amounts of delmopinol. The autoradiography results confirmed that delmopinol was bound to proteins of high molecular weight (700-600 kDa).

Retention.
This article describes the mechanisms for retaining RPDs and considers the different types of direct retainer. The factors influencing the effectiveness of retentive clasps and governing the choice of clasp are discussed.

A system of design.
This article describes a method of building RPD components into an effective design and indicates how the details of the design can be communicated clearly to the dental technician.

Communication between the dentist and the dental technician.
Factors contributing to good RPD design are described, including the respective inputs of the dentist and dental technician. Poor communication in current practice is reported and an appropriate format for a work authorization presented.

The removable partial denture equation.
This article describes the benefits and risks of providing RPDs. It emphasises the importance of co-operation between the dental team and patient to ensure that the balance of this 'equation' is in the patient's favour.

Immediate functional loading of Brånemark dental implants. An 18-month clinical follow-up study.
A clinical and radiographical study was performed to compare the outcome of oral rehabilitation in the edentulous mandible by fixed supraconstructions connected to implants installed according to either i) a 1-stage surgical procedure and immediate loading (Experimental Group-EG), or ii) the original 2-stage concept (Reference Group-RG). The EG comprised 16 subjects with edentulous mandibles. Beyond the non-smoking criteria the following specific inclusion criteria were adopted: i) all patients had to consider themselves to be in good general health, ii) the amount of bone had to enable the installation of 5-6, at least 10 mm long fixtures to be bicortically anchored (Mk II fixtures; Nobel Biocare AB, Göteborg, Sweden) between the mental foramina, and iii) the patients had to be available for the follow-up and maintenance programme. A total of 88 implants were placed in the EG (16 patients) compared to 30 in the RG (11 patients). In the EG, fixed appliances were connected to the implants within 20 days following implant installation while the fixed appliances in the RG were connected about 4 months following fixture installation. At the time for delivery of the supraconstructions all 27 patients were radiographically examined, an examination that was repeated at the 18-month follow-up. The analysis of the radiographs from the EG disclosed that during the 18-month observation period the mean loss of bone support amounted to 0.4 mm. The corresponding value observed in the RG was 0.8 mm. During the 18-month observation period no fixture was lost in any of the 2 groups examined. The implants under study as well as those in the reference material were at all observation intervals found to be clinically stable. The present clinical study demonstrated that it is, at least based on an 18-month observation period, possible to successfully load titanium dental implants immediately following installation via a permanent fixed rigid cross-arch supraconstruction. However, such a treatment approach has so far to be strictly limited to the inter-foramina area of the edentulous mandible.

Bioadhesion--a phenomenon with multiple dimensions.
This paper reviews some relevant citations regarding the non-specific forces that must be considered in oral bioadhesive events. These range from forces related to restorative dentistry to those related to prevention and molecular biology. Types of interactions discussed are: 1. Van der Waal's forces; 2. electrostatic double-layer forces; 3. solvent-dependent interactions; 4. hydrogen bonding; 5. hydrophobic interactions; 6. hydration forces; 7. steric forces; and 8. covalent bonds. Examples are given of the various types of interaction that occur at different surface separation (< or =400 A) between adsorbed films of a pure salivary protein fraction (PRP1).

Biomaterial considerations for the optimized therapy for the edentulous predicament.
A range of biomaterials are used in rendering prosthodontic treatment for the completely edentulous patient. This article reviews the biomaterials considerations in the use of metals and metal alloys, ceramics and carbons, and synthetic materials for implant therapy. It also discusses implant material selection, biomaterial aspects of bioadhesion, and osseointegration and hygiene-related biomaterial factors.
