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)

Cleft lip and/or cleft palate defects often result in a functional deficiency in the patient’s chewing, speech ability, and aesthetic appearance, usually demanding multidisciplinary effort for addressing the aesthetic and functional patient’s requirements. This clinical report describes the planned oral rehabilitation of a 46-year-old woman with unilateral cleft lip defect based on the patient’s peculiarities and age. Due to limitations concerning bone grafts and implant procedures, as well as orthodontic treatment, the prosthodontic rehabilitation using the metal-ceramic fixed partial denture was chosen. The treatment adequately reestablished the aesthetic and functional activities, positively impacting the patient’s quality of life.

AbstractRehabilitation of patients with deficient Seibert's Class-III ridge mandibular ridge is always a challenge for a dentist. This article discusses the problems faced while rehabilitating such cases and also discusses the surgical and prosthetic management of one such case. A ridge augmentation procedure called as “Roll on Technique” was used to correct the contour of the ride. Fixed partial denture with altered framework design and tissue colored porcelain was used to complete the case. These simple but effective changes helped to give predictable esthetics with illusion of natural teeth.

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.
