This study was performed as an adjunct to an existing clinical study to validate the effect of veneer: framework thickness ratio on stress distribution in an implant-supported all-ceramic fixed partial denture. Two commercially available titanium dental implants with corresponding customized abutments and a patient-retrieved all-ceramic fixed partial denture were scanned using a high-resolution micro-CT scanner. Reconstructed 3D objects, along with a simulated bone surface, were incorporated into a non-manifold assembly and meshed simultaneously using Simpleware software (Synopsys Simpleware ScanIP Version P-2019.09; Mountain View, CA). Three such volume meshes (Model A, Model B, Model C) corresponding to veneer: framework thickness ratios of 3:1, 1:1, and 1:3 respectively were created, and exported to a finite element analysis software (ABAQUS). An axial load of 110 N was applied uniformly on the occlusal surfaces to calculate the static stresses and contour plots were generated in the post-processing module. From the data obtained, we observed optimum stress distribution in Model B. Also, the tensile stresses were concentrated in the posterior connector region of the prosthesis in all three models tested. Within the limitations of this study, we can conclude that equal thickness of veneer and framework layers would aid in better stress distribution.

ABSTRACTAll ceramic fixed partial dentures (FPD)s exhibit enhanced biocompatibility and esthetics as compared to metal-ceramic restorations. However, framework fractures are frequently reported especially when the connector dimensions are inadequate to withstand the high tensile stresses. The repair of the failed connector would be desirable rather than the complete removal and renewal since the latter is an expensive and time consuming procedure. Furthermore, the replacement or removal of the restoration for extra-oral repair purposes might increase the risk of destroying the entire restoration or damaging the abutment teeth during the removal. This article presents a direct intra-oral method that may be used to repair the connector fractures of all-ceramic FPDs which are otherwise clinically satisfactory. In the present technique, the connector is reconstructed intraorally utilizing composite resin restorative material reinforced with E-glass-fiber. (Eur J Dent 2008;2:63-68)

Implant Prosthesis

Passive fit of a long-span screw-retained implant prosthesis is an important criteria for the success of the restoration. This article describes a technique for fabricating a ceramometal implant fixed dental prosthesis (FDP) for a long-span partially edentulous situation by altering the conventional screw-retained design. The possibility of a passive fit is maximized by intraoral luting of the cast frame to milled abutments, and the potential framework distortion during fabrication is compensated to a major extent. Retrievability is ensured by screw retention of the prosthesis to the implants. Compared with conventional porcelain fused to metal screw-retained FDP, this prosthesis is relatively inexpensive to fabricate.

The realization of esthetic objectives and functional demands in the reconstruction of severely compromised dentition represents considerable clinical problems. This clinical report represents the prosthetic management of a severe dentofacial deformity with compromised periodontal status. Treatment objectives were based on Aesthetics enhancement, sociopsychological support of the patient, restoration of form function, phonetics and comfort. Following which extraction of upper incisors and alveoloplasty done. An immediate removable partial denture was fabricated, considering aesthetics, phonetics and comfort of the patient followed by replacement of incisors by metal- ceramic fixed partial denture done. Clinical relevance: prosthetic management of severlymalaligned natural maxillary anterior teeth by fixed partial denture, considering aesthetics and phonetics of the patient. Treatment objectives: Aesthetics enhancement, sociopsychological support of the patient, restoration of form function, phonetics and comfort.

Abstract Aim This clinical report describes a conventional resin-based fixed partial denture for a 42-yearold woman to close an edentulous space in the region of the second maxillary premolar. While the first maxillary molar had been crowned with porcelain fused to metal (PFM) system 10 years ago and the first premolar was intact and sound except for a small carious lesion in the distal aspect. The essential clinical and laboratory procedures are illustrated. Background Multiple clinical studies document excellent long-term success of resin-bonded fixed partial dentures. In the 1970s, the Rochette resin-bonded fixed partial denture (RBFPD) was introduced. Next, to enhance retention and resistance form of posterior RBFPD preparation of parallel guide surfaces on the interproximal aspects of the adjacent teeth along with rests on the occlusal aspects to counteract dislodging forces was recommended. Report A 42-year-old woman presented with an extracted left maxillary second premolar. The first maxillary molar had been crowned 10 years ago and the first premolar had a small carious lesion in the mid distal of proximal aspect. To eliminate unnecessary cutting of the PFM of the first molar and crown preparation of the first maxillary premolar, the use of RBFPD was suggested and accepted by the patient. Summary This clinical report described the indication, the selection of a PFM-crowned abutment, and clinical procedures involved in the fabrication of RBFPD that provided a conservative solution for replacement of one posterior tooth. Clinical Significance RBFPDs can be used successfully in both the anterior and the posterior regions of the mouth to replace one or two missing teeth. However, the survival rate of RBFPDs is still considerably less than that of conventional fixed partial dentures. The principal reason for failure is debonding of the framework from the abutment tooth. The selection of nonmobile abutment teeth, the preparation design that enhances retention and resistance form, and the tooth bonding technique are critical for success.
