Replacing an anterior metal-ceramic restoration with an all-ceramic resin-bonded fixed partial denture: a case report

Since the first resin-bonded fixed partial denture was described, this adhesive technique for splinting mobile teeth has developed into a conservative method for replacing missing teeth. Heat-pressed all-ceramic materials have been introduced for the fabrication of 3-unit fixed partial dentures in the anterior and premolar region. This clinical report describes the replacement of a conventional partial coverage metal-ceramic resin-bonded fixed partial denture with an all-ceramic resin-bonded fixed partial denture in the anterior maxillary area.     

Successful use of a single-retainer all-ceramic resin-bonded fixed partial denture for replacement of a maxillary canine: a clinical report.

This clinical report describes the prosthodontic treatment of a 60-year-old woman to close an edentulous space in the region of the maxillary canine. Single-retainer resin-bonded fixed partial dentures (FPD) have shown satisfactory results in different studies. Recent in vivo studies have shown excellent results for all-ceramic anterior FPDs after 5 years. In the present situation, a cantilevered all-ceramic FPD chosen to replace a missing maxillary canine showed success at the 2.5-year follow-up. Special attention was given to functional and minimal restorative considerations. The use of single-retainer all-ceramic FPDs is discussed. The present case does not represent a routine and well-documented approach for the replacement of a missing maxillary canine. Rather, it is a rarity that was successful because of space availability, present occlusal scheme, and patient cooperation. Implant-supported restorations always should be considered as the first treatment option in such a clinical situation.     

Replacement of missing posterior teeth with an all-ceramic inlay-retained fixed partial denture: a case report

Adhesively luted all-ceramic inlay-retained fixed partial dentures can be a clinical alternative for the replacement of missing posterior teeth in certain situations. This type of restoration allows satisfactory esthetics and reduced tooth preparation compared to a conventional metal-ceramic fixed restoration. This case report describes the use of an inlay-retained fixed partial denture as a conservative alternative for the replacement of missing posterior teeth.     

A stress-relieved resin-bonded fixed partial denture

Reports of bonding failures with resin-bonded fixed partial dentures (commonly called the "Maryland Bridge") are common. Failures are due to individual tooth mobility as much as they are to bonding inadequacy. The incorporation of stress relievers in the design of resin-bonded fixed partial dentures has created a dramatic reversal in bonding failures.     

An application of a splint purposeful resin-bonded fixed partial denture after orthodontic treatment: a case report

An adult male patient who had lost his maxillary left central incisor seven years ago in a traffic accident presented with a chief complaint about his unaesthetic appearance associated with the loss of his maxillary left central incisor space, a Class III molar occlusion, and an anterior open bite malocclusion due to tongue-thrust swallowing. Fixed orthodontic treatment was rendered following fan-type expansion of the maxilla. A Maryland bridge as a minimally invasive dentistry approach was used as a retention appliance and the patient's aesthetic appearance was restored.     

A nine-year clinical case study of a resin-bonded fixed partial denture seated on the maxillary anterior teeth

PatientThis report describes the longevity of a resin-bonded fixed partial denture (RBFPD). This denture was seated on the maxillary anterior teeth with minimal tooth preparation. The RBFPD was cast from a silver–palladium alloy (Castwell M.C. 12), and the pontic was veneered with an indirect composite material (Estenia). The retainers were primed with a metal conditioner (V-Primer) and seated with a tri-n-butylborane initiated adhesive resin (Super-Bond C&B). After an observation period of eight years, a fracture occurred in the incisal edge of the central incisor abutment. The fractured area was restored with light-polymerizing composite resin and the anterior guidance was re-adjusted.DiscussionRBFPD abutment teeth with deep vertical overlap should be carefully prepared to avoid abutment tooth fracture.ConclusionThe clinical performance of the RBFPD made from a silver–palladium–copper–gold alloy was sufficient when seated with tri-n-butylborane initiated adhesive resin after surface modification using vinyl-thiol primer.Clinical significanceThe use of vinyl-thiol primer and tri-n-butylborane initiated adhesive resin is a clinically reliable bonding system for seating resin-bonded fixed partial denture (RBFPD) made from a silver–palladium–copper–gold alloy. The RBFPD, based on a reliable bonding system, can clinically function for a long time, even if the vertical overlap of the abutment teeth is excessive.     

Anterior maxillary resin-bonded fixed partial denture to preserve occlusal surface area for anterior guidance. A clinical report

One of the problems with anterior maxillary resin-bonded fixed partial dentures is anterior-guided occlusion. An anterior maxillary resin-bonded fixed partial denture was fabricated. The reduction of the lingual surface of the abutment was restricted to the nonocclusal surface area for anterior guidance. The patient's original mandibular movement did not change after the denture was seated. The denture has been functioning satisfactorily without any problems for more than 72 months. This article emphasizes the concept of fabricating an anterior maxillary resin-bonded fixed partial denture without reduction of the occlusal surface area for anterior guidance.     

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.     

Single tooth replacement using a modified metal-ceramic resin-bonded fixed partial denture: a clinical report

This article describes the use of a modified metal-ceramic resin-bonded fixed partial denture (MMC RBFPD) as a conservative solution for the replacement of an incisor. It is a minimally invasive technique which does not discolor the abutment teeth.

Longevity of a maxillary 2-unit cantilever fixed partial denture: clinical report

In this clinical report, we discuss the length of service and subsequent replacement of a maxillary anterior 2-unit cantilever fixed partial denture (FPD). The FPD provided 53 years of service to the patient and was finally replaced with a 2-unit porcelain-fused-to-metal (PFM) FPD. The original prosthesis replaced a missing maxillary lateral incisor using a partial coverage metal retainer, whereas the new FPD was designed with a complete coverage PFM retainer.

Treatment of a microvascular reconstructed mandible using an implant-supported fixed partial denture: case report.

Oral rehabilitation of patients with mandibular discontinuity defects is a problem that faces both the oral surgeon and the restorative dentist. Advances in microvascular surgery can provide the mandible with vital bone grafts. Often, reconstruction of the bony defect alone does not guarantee an adequate foundation for successful conventional prosthetic rehabilitation. Osseointegrated implants placed in the microvascularized grafted bone offer an opportunity for improved function and patient satisfaction. This case report describes the use of an implant-supported bridge in a vascularized fibular bone graft to reconstruct a traumatic partially resected mandible.     

Replacement of two mandibular central incisors using a zirconium resin-bonded fixed partial denture: a clinical report

Maxillary and mandibular anterior tooth loss may cause esthetic and functional problems. Successful treatment for these situations may necessitate a minimally invasive technique to preserve sound remaining abutment tooth structure. This article describes the use of zirconium resin-bonded fixed partial denture as a conservative treatment option for the replacement of 2 mandibular central incisors.     

Clinical long-term survival of two-retainer and single-retainer all-ceramic resin-bonded fixed partial dentures.

OBJECTIVES: All-ceramic resin-bonded fixed partial dentures (RBFPDs) were introduced as a conservative treatment approach 15 years ago. The purpose of this prospective study was to evaluate the long-term clinical survival of RBFPDs made with a conventional two-retainer design or a cantilever single-retainer design. METHOD AND MATERIALS: A total of 37 anterior RBFPDs were made from the glass-infiltrated alumina ceramic In-Ceram. Sixteen RBFPDs with a conventional two-retainer design were inserted in 14 patients, and 21 RBFPDs with a cantilever single-retainer design were inserted in 16 patients. Panavia or Panavia 21 were used as luting agents either after silica-coating and silanation or after air-abrasion only. Patients were recalled every year for a clinical examination to evaluate the restorations with regard to function and possible failures. The mean observation time in the two-retainer group was 75.8 months, and in the single-retainer group it was 51.7 months. RESULTS: No restoration debonded. In the two-retainer group, one restoration was lost because it fractured after 3 months at both connectors and one restoration was removed alio loco accidentally. Also in this group, four RBFPDs fractured within 15 months after insertion at one connector, but the pontic remained in situ as a cantilever RBFPD for several years. In the single-retainer group, only one FPD fractured and was lost 48 months after insertion. The 5-year survival rate was 73.9% in the two-retainer group and 92.3% in the single-retainer group. When unilateral fracture of a FPD was taken as criterion for failure, the five-year survival rate decreased to 67.3% in the two-retainer group. CONCLUSIONS: Cantilever all-ceramic resin-bonded fixed partial dentures made from high-strength oxide ceramics present a promising treatment alternative to two-retainer RBFPDs in the anterior region.
