Diastema preservation in resin-bonded fixed partial dentures.

The etched-metal, resin-bonded fixed partial denture has evolved rapidly from its origination as an extracoronal splint. Technologic advancements in both resin chemistry and retentive surface etching techniques have markedly improved the quality of the prosthesis. Today, resin-bonded fixed partial dentures are an effective, conservative means of replacing missing teeth when specific contra-indications--long spans, insufficient sound enamel, malocclusion, pathologic occlusal habits--are identified and avoided. A universally-accepted standard preparation does not exist for resin-bonded fixed partial dentures; rather, common principles of tooth reduction are agreed upon by most authors. This case report details necessary modifications in typical preparation and framework design that must be included to maintain a midline diastema when such spacing is required or preferred by the patient.

The design of a two-part acid-etched resin-bonded fixed partial denture.

A new framework design is presented for resin-bonded, acid-etched, fixed partial dentures. This innovative design divided the restoration into two parts, each with a separate path of insertion. The preparation of abutment teeth required minimal reduction and the pontic could not be displaced during function. Thirty-five patients with missing posterior teeth have been treated with this imaginative approach and after approximately 2 years, there have been no debonding failures.

Replacing a failed resin-bonded fixed partial denture with a single tooth implant.

When adequate width and height of remaining alveolar bone is present, the implant-supported fixed prosthesis is an excellent alternative in replacing a missing tooth. The prosthetic tooth, supported by an endosseous implant, emerges from the tissue in a manner which resembles the natural tooth it replaces better than any other treatment option available. This article presents one clinical case history, preclinical treatment phase, and actual clinical treatment.

Improved retention of acid-etched fixed partial dentures: a longitudinal study.

Debonding of acid-etched fixed partial dentures has been a problem since their introduction. A study was conducted to determine whether this problem could be resolved by modifying the mechanical retention of tooth preparations. Retentive grooves were prepared at the line angles to create mechanical locks for the resin bonded fixed partial denture. The 4-year retention of posterior resin-bonded fixed partial dentures improved from 60% to 95% by the placement of the proximal grooves. This study was conducted in a dental school clinic during a period of 10 to 52 months. The results demonstrated that design modifications were necessary to improve clinical longevity so that the restoration could be considered "permanent" in the traditional sense. The less-experienced dentist may be more confident of the treatment with the recommended modifications and projected longevity.

A pin-assisted retention technique for resin-bonded restorations.

The value of pins for auxiliary retention has been demonstrated many times. The use of pins with resin-bonded restorations allows for improved aesthetics and less tooth reduction while increasing resistance to dislodging forces. Clinical and technical procedures for resin-bonded bridges with pin-assisted retention are presented.

Alternative restorative approach: a clinical report.

This clinical report describes a technique for restoring a maxillary right posterior segment using a combination of a conventional full-coverage retainer and adhesive resin-bonded retainer with a nonrigid connection, periodontal ridge augmentation, and a coronal-radicular amalgam alloy core. A technique has been outlined that allows for the preservation of the maximum amount of natural tooth structure while restoring a maxillary right posterior segment.

An analysis of multiple failures of resin-bonded bridges.

A clinical trial involving 203 resin-bonded bridges (RBBs) was undertaken to investigate the influence of several variables on the survival of these prostheses. This article presents the experiences with rebonded and replacement RBBs after failure of the originally bonded RBBs. A total of 62 dislodged and rebonded RBBs was included in this study and evaluated using Kaplan-Meier estimates. Rebonded RBBs that dislodged for a second time were replaced by another type of RBB ('replacement' RBBs, n = 32). The study revealed that rebonded RBBs were more susceptible to dislodgement than originally bonded RBBs. Fifty per cent survival was reached 2.1 years after rebonding. The sooner the first dislodgement occurred, the lower the retention rate of the rebonded RBB (PH-model, beta = 0.78, P = 0.02). Also some failure characteristics were evaluated. Failure characteristics (i.e. fracture site and partial versus complete dislodgement) of first and second dislodgement were not correlated (Chi-square, P values > 0.25). The survival of 'replacement' RBBs was significantly better than the survival of multiply failure RBBs (median survivals respectively 1.6 years and 1.0 year, P = 0.03). From the results of this study it may be concluded that the survival rates of rebonded and replacement RBBs were unacceptable.

Costs and Cost Analysis↗

A method to compare cost-effectiveness of dental treatments: adhesive bridges compared to conventional bridges.

The cost-effectiveness of a dental restoration depends primarily on the durability and the cost of the restoration. In this report a method is described to compare the cost-effectiveness using the durability data of adhesive bridges and conventional bridges. The study shows that, for the situation in the Netherlands, the breakeven point for equal cost-effectiveness compared to conventional bridges is achieved when the 50% survival for adhesive bridges is approximately 6.5 yr. Clinical data indicate a higher cost-effectiveness for anterior adhesive bridges. The method described in this report is considered to be useful for comparing cost-effectiveness of dental restorations in different situations.

A seven-and-a-half-year survival study of resin-bonded bridges.

A clinical trial, concerning 203 resin-bonded bridges (RBBs), was performed for investigation of the influence of retainer-type and cementation materials on the survival of these restorations. The survival rates after a 7.5-year follow-up were 75% for anterior RBBs and 44% for posterior bridges. Etched metal RBBs (E-bridges) were significantly more retentive than perforated RBBs (P-bridges); the survival rates were 78% and 63%, respectively. With respect to the cementation materials, Clearfil F, in combination with E-bridges, had the best overall survival (89%, anterior and posterior). Maxillary anterior RBBs were more susceptible to failure than mandibular anterior RBBs.

Incisor spacing: a sequential orthodontic restorative treatment approach.

For those patients presenting with one or more missing incisors, a sequential technique utilizing specific arch wires to level and align the irregular incisor teeth may be used. Auxiliary coil springs are then fitted to redistribute the space prior to the preparation of a prosthesis, the fabrication of which is facilitated by parallel and upright abutments. The space obtained allows esthetically proportioned pontics. Two cases that illustrate this technique are presented.

Alternatives to gold.

Despite, or perhaps because of, its antiquity the lost wax casting process which we use in dentistry still produces the most accurate and durable restorations in our armamentarium. Although high-gold content alloys still act as the benchmark of quality, fit, and durability in the aggressive conditions of the mouth, their inherent cost, high density and low modulus have stimulated a search for alternatives. This has ranged widely through the metallurgical world and across the periodic table of the elements. As a result dental alloys for casting into inlays, crowns and bridges (with or without facings of dental porcelain) have become incredibly complex. This article will explain some of the reasons behind the developments.

Clinical evaluation of resin-bonded prostheses.

Resin-bonded prostheses were clinically evaluated following a mean period of 41 months. The abutment teeth were minimally prepared, and one groove was placed on the surface approximating the edentulous space. Retainers were treated using the Silicoater technique. Thirty-four prostheses were made for 32 patients. Four patients were lost from the study and 30 units were re-examined. Two prostheses had debonded. The results suggest that resin-bonded prostheses can be successful if meticulous attention is given to the procedures outlined.
