Achieving immediate function with provisional prostheses after implant placement: a clinical report

When using a conventional implant treatment protocol in edentulous patients, reduced function and comfort for up to 6 months after implant surgery is inevitable until bone healing is complete and a prosthesis is securely attached to the implants. The following report highlights 2 treatment modalities that enable immediate function by inserting provisional prostheses immediately after implant placement.     

Use of a prefabricated fiber-reinforced composite resin framework to provide a provisional fixed partial denture over an integrating implant: a clinical report

The development of fiber-reinforced composites offers new possibilities in minimally invasive tooth replacement approaches. This article describes the use of a prefabricated fiber-reinforced composite resin framework for the chairside fabrication of a provisional fixed partial denture over an integrating implant. The framework fabrication, theory, and a clinical scenario are illustrated.     

Use of an implant in repair of a fixed partial denture. A clinical report.

A repair technique for a fractured solder joint in a multiple-unit fixed partial denture has been presented. The advantages of this technique include (1) retention of part of an existing restoration; (2) provision of additional support to minimize future fracture; (3) removal of the implant crown for periodic evaluation and/or treatment; and (4) retention of a fixed partial denture where a removable prosthesis might otherwise be needed. The primary disadvantage of this technique is the time and expense associated with implant placement.

The fabrication of fixed implant-supported prostheses for edentulous patients may be performed using all-ceramic or acrylic resin materials. This clinical report describes the fabrication and 2-year follow-up of maxillary zirconia implant fixed partial dentures opposing a mandibular acrylic resin screw-retained fixed complete denture.     

Adhesive placement of a zirconia fixed partial denture to replace a maxillary central incisor: a clinical report

The replacement of a single maxillary incisor is an esthetic challenge. Many options provide various degrees of longevity and ease of fabrication. The introduction of zirconia-supported fixed partial dentures (FPDs) has seen increased use in the last several years. However, abutment preparation guidelines and laboratory fabrication have to adhere to the guidelines established by the manufacturers and clinical researchers. Zirconia FPDs can provide long-term strength and esthetics if they are designed and fabricated appropriately.     

Fracture of a fixed partial denture abutment: a clinical report

Commonly observed complications associated with a conventional fixed partial denture (FPD) include loss of retention and tooth fracture. This report describes the occurrence of an unusual FPD abutment fracture and subsequent treatment. The distal abutment of an FPD developed severe periodontal disease with mobility. The anterior abutment fractured in the middle of the clinical crown and experienced cement failure.     

Fabrication of an indirect-direct provisional fixed partial denture

This article describes a procedure for fabricating an optimal provisional restoration before tooth preparation. The procedure involves the fabrication of an indirect-direct provisional fixed partial denture. There are several advantages to this procedure, such as reduced chair time, less heat generated in the mouth, reduced contact between resin monomer and soft tissues, and optimal esthetics.     

Collarless metal ceramic fixed partial denture: a clinical report.

A case of a collarless metal ceramic fixed partial denture with preparations made at a slightly supragingival level is reported. The absence of the metal collar in the buccal portion of the abutments provides an excellent esthetic appearance. The use of a collarless metal ceramic fixed partial denture is a viable approach for restoring dentition where the esthetic quality is the primary concern.     

Replacement of a maxillary central incisor using a polyethylene fiber-reinforced composite resin fixed partial denture: a clinical report

Fiber-reinforced composite resin (FRC) restorations generally consist of a composite resin veneer supported by a fiber-reinforced composite resin substructure and prepared chairside to be used when the patient needs a short-term solution. It is an esthetic, conservative treatment alternative and allows for future options. This article describes the use of a polyethylene fiber-reinforced composite resin fixed partial denture (PFRCFPD) with a ceramic pontic for the replacement of a missing central incisor due to trauma.     

Use of a resin-bonded fixed partial denture with a removable pontic during the osseointegration period of a single implant treatment: a clinical report

This clinical report describes the construction of a resin-bonded fixed partial denture with a removable pontic during the healing period of a single implant treatment. This design improves maintenance of oral hygiene.     

Management of interproximal soft tissue with a resin-bonded prosthesis after immediate implant placement: a clinical report

This report describes immediate implant placement after the extraction of a vertically fractured tooth. During the healing phase, a resin-bonded prosthesis was inserted as a provisional restoration. After the creation of the optimal emergence profile and papillae with the provisional restoration, the definitive metal ceramic crown was fabricated.     

Immediate placement and immediate provisional abutment modeling in anterior single-tooth implant restorations using a CAD/CAM application: a clinical report

A patient underwent immediate implant placement and immediate provisional restoration with nonocclusal loading in the right central incisor area. A provisional custom abutment and a cemented provisional restoration were fabricated. At the impression appointment, an implant level impression was made and the provisional abutment was scanned for fabrication of the definitive custom abutment. This clinical report describes how CAD/CAM technology can facilitate the definitive restoration of immediately placed and loaded implants by allowing the fabrication of the definitive abutment as an exact duplicate of the provisional abutment.     

Using a fixed provisional prosthesis during post-extraction healing and implant placement

Most dental patients insist on the use of provisional prostheses throughout healing and osseointegration when replacing extracted teeth with implants in esthetically sensitive areas. Removable appliances of some kind are normally used for this purpose, but patients often consider them to be too cumbersome. This can lead to decreased case acceptance and compliance with the use of the provisional restoration, which can compromise the final result of treatment. Custom fixed solutions to this problem exist, but they tend to be more complicated, less practical, and more expensive than other options now available. The Monodont bridge, a new system of prefabricated components for the creation of provisional fixed partial dentures, can be more esthetic, more retentive, more functional, more cost-effective, and more universally applicable than any other available techniques. This can raise patient tolerance of provisional prostheses and thus increase case acceptance, while fostering a more predictable esthetic result with regard to soft tissue contours and emergence profile.     

Use of an alternative pontic foundation technique for a fiber-reinforced composite fixed partial denture: a clinical report

This article describes the treatment of a patient for whom a fiber-composite laminate dowel and core and polyethylene fiber were used as a conservative alternative to provide a dowel-and-core and fixed partial denture foundation. The treatment plan included removing the existing restoration on the maxillary right first molar, placing a fiber-reinforced resin dowel and core for retention and reinforcement of the maxillary first premolar, and fabricating a definitive restoration using polyethylene fiber to reinforce the fixed partial denture.     

Color stability of provisional crown and fixed partial denture resins

STATEMENT OF PROBLEM: Provisional resins are used extensively during fixed prosthodontic treatment and exhibit varying degrees of color change/discoloration over time. Data are needed to help predict color stability of provisional resins. PURPOSE: The purpose of this in vitro study was to measure the color change of 12 provisional prosthodontic materials after immersion in artificial saliva and artificial saliva-coffee solutions for 1, 2, and 4 weeks. MATERIAL AND METHODS: Twelve provisional materials were studied. Methacrylates consisted of Alike, Jet, Temporary Bridge Resin, Unifast, and Zeta CC. Bis-acryl resins included Instatemp, Integrity, Luxatemp, Protemp Garant, Provipont, Provitec, and Temphase. Ten specimens (25.4 mm x 25.4 mm x 2.4 mm) of each material were fabricated. Five specimens were stored at 37 degrees C in artificial saliva and 5 were stored in a solution of artificial saliva (400 cc) and coffee (800 cc). Baseline color was measured using a colorimeter. Further color measurements were made after 1, 2, and 4 weeks of immersion. CIE L *a *b * values were recorded and color differences (DeltaE) between baseline and each storage interval were calculated using a 2-way ANOVA with Bonferroni adjustment for multiple comparisons in conjunction with an overall alpha=.05. RESULTS: Results indicated the presence of strong interaction between material and storage solution regardless of the aspect of color considered (P<.0001 for DeltaE, DeltaL *, Deltaa *, and Deltab *). Coffee solution relative to saliva solution had the most significant impact on color change for Luxatemp, Protemp, and Temphase materials at 4 weeks, but the greatest overall color change for both coffee and saliva solutions was found for Provipont (DeltaE=9.40 coffee; 8.51 saliva) and the least overall color change for both solutions was found for Zeta CC (DeltaE=0.31 coffee; 0.23 saliva). CONCLUSIONS: Under the conditions of this study, 12 provisional crown and fixed partial denture resins demonstrated varying tendency to discolor over a range of time periods when immersed in artificial saliva and artificial saliva-coffee solutions.
