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.

Background Gingival inflammation and periodontal disease are the common complications of fixed dental prosthesis. They can be overcome by good oral hygiene maintenance.Objective The objective of this study was to assess the oral hygiene and gingival condition in patients after placement of fixed dental prosthesis for a period of six months. It was also analyzed how factors like type of fixed dental prosthesis (Single crown, fixed partial denture) and material (Metal, Porcelain fused to metal) are statistically associated with oral hygiene and gingival health.Method The sample consisted of 50 patients visiting the Dental Outpatient Department of Dhulikhel Hospital. The oral examinations were conducted using basic diagnostic tools (Mouth mirror, periodontal probe and explorer). Teeth and gingiva were examined using the Plaque and Gingiva Index by Silness and Löe. The examinations were conducted after 14 days and six months after placement of fixed dental prosthesis along with the oral hygiene instructions. Paired sample t-test were done to find statistical association using SPSS 16.0.Result Our results revealed no significant difference in plaque index among patients with single crown whereas fixed partial denture showed statistical significance. No significant differences were found for type of material. The statistical analysis showed similar results for gingival index.Conclusion Our research showed that single crown had no significant difference on Plaque index and Gingival index of the patient after 14 days and six months, whereas, Fixed partial denture showed significant difference. Both metal and porcelain fused to metal crown revealed no statistically significant difference on Plaque index and Gingival index.

Resumo A cerâmica odontológica tem sofrido modificações na composição visando melhorar sua resistência em resistir às forças mastigatórias fisiológicas na região posterior da boca. O objetivo deste trabalho foi avaliar o comportamento clínico de próteses parciais fixas posteriores (PPFs) em zircônia a partir de estudos clínicos prospectivos de 3 anos ou mais. Realizou-se revisão sistemática da literatura por meio de pesquisa na base de dados PubMed em busca de publicações em inglês entre os anos de 2004 e 2014 com os seguintes descritores e suas combinações: 'fixed partial denture' OR 'dental prosthesis' OR 'dental porcelain' OR 'FPD' AND 'zirconia'. A busca resultou em 282 artigos, 20 foram lidos na íntegra e então oito selecionados. Os sistemas de zircônia utilizados foram Lava (3M ESPE), Cercon (DeguDent) e Denzir (Cad.esthetics) com cimentação variando entre resinosa, com ionômero de vidro e fosfato de zinco. A quantidade total de pacientes examinados foi de 199, com 241 próteses instaladas, avaliados em um período de 3 a 7 anos. Destas, oito apresentaram fratura da infraestrutura em zircônia, 41 sofreram fratura apenas da cerâmica de recobrimento e 17 tiveram perda de retenção sem fratura; 17 dentes pilares sofreram cárie secundária, três fraturaram e nove necessitaram de tratamento endodôntico. A taxa de sobrevida das PPFs variou de 73,9% a 100%. Concluiu-se que a zircônia está apta a ser utilizada na região posterior, porém estudos são necessários para averiguar as causas das lascas do revestimento. Mediante as falhas na cimentação, recomenda-se seguir rigorosamente as instruções do fabricante e atentar para um preparo dental adequado.

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)

The aim of this paper is to report a clinical case with bilateral missing mandibular second premolars that were restored by metal-ceramic inlay-retained fixed dental prostheses. The first prosthesis was of a traditional design and the second was of a modified design. The suggested design is created by modifying the retainer wings of the traditional resin-bonded inlay-retained fixed dental prosthesis and covering the wings with composite resin. The modified design is relatively conservative, esthetic and provides an extra element for the retention of posterior metal-ceramic inlay-retained fixed dental prostheses.

ABSTRACTAn abutment for a fixed partial denture may not contain enough tooth structure, such that the abutment does not provide an adequate ‘ferrule effect’. A crown or bridge dental prosthesis that is cemented onto such an abutment/s may undergo biomechanical failure. Here, the tooth, core, and post complex, on which the crown is cemented, may fracture off from the abutment, causing the crown to separate from the abutment, while the cement that bonds the crown to the tooth, core, and post complex remains intact, such that the tooth, core, and post complex remains inside the crown when the crown separates from the abutment. This article reviews the dentistry literature on the ferrule effect, and presents alternative definitions for terms such as ferrule, the ferrule effect, and the ferrule tooth structure. The article also explains how the use of a surgical operating microscope, or high magnification binocular surgical loupes of ×6-8, or greater magnification improve the ability of a dentist to assess how much ferrule tooth structure an abutment contains, compared to the use of unaided vision.

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.
