“…The authors are tempted to interpret this as a confirmation of the hypothesis. Moreover, these results endorse other studies that identify caries as the main cause of failure, 7,15,20,22,23,[32][33][34][35] while studies based on FDPs with more abutments in function for an equal replacement of missing teeth 18,[36][37][38][39][40] reported loss of retention as the main cause of failure. Caries detection was assumed to be a secondary problem caused by the loose retainer.…”

Purpose: This study evaluated treatment outcomes of 4-unit porcelain-fused-to-gold fixed dental prostheses (FDPs) replacing 2 adjacent missing teeth. Materials and Methods: A total of 102 FDPs made in an undergraduate university clinic for 73 patients were evaluated for up to 20 years, with a mean survival follow-up time of 11.4 years. All patients were offered an oral health maintenance program. Treatment failures were divided into irreversible (loss of FDPs/finish line involved) or reversible (FDPs and finish line intact after conservative treatment) complications and into biologic and technical/patient-related failures. Results: The Kaplan-Meier overall estimated survival rate was 68.3% at year 20. There was a statistically significant difference (P = .007) between the survival rates in the maxilla for the vital group (73.8%) and those for the root canal-treated group (25.1%). Comparing the survival rate in the root canal-treated group for the restorations in the maxilla (25.1%) versus the mandible (66.8%), a statistically significant difference (P = .011) was found. The main reason for irreversible failure was caries (32.0%). Conclusion: The estimated successful outcome of 4-unit FDPs over an up to 20-year period is considered favorable and should be compared with the survival rates of other treatment options for the replacement of 2 adjacent teeth. Occurrence of a previously reversible complication appears to be a predictive factor for an irreversible complication later on. A reversible complication within the first 2 years will lead to an early irreversible complication. Int J Prosthodont 2008;21:259-266.

“…Several clinical studies [1][2][3] reported that fixed partial dentures on natural teeth had a mean life span of 5 to 13 years, while implant-supported fixed prostheses demonstrated a survival rate greater than 90% 4,5) at 10 to 15 years. These findings suggest that prosthetic treatments using dental implants are comparable to traditional prosthetic procedures in carefully selected clinical cases.…”

Retention of crowns cemented on implant abutments with temporary cements

This study was to examine the retentive force of crowns to implant abutments with commercial temporary cements. Six different temporary cements were investigated. Cast crowns were cemented to the abutments using each cement and their retentive forces to abutments were determined 7 or 28 days after cementing (n=10). The retentive force of the cements to abutments varied widely among the products [27-109 N (7-day), 18-80 N (28-days)]. The retentive force of all the cements was not reduced as the time elapsed, except for two products tested. The polycarboxylate cements and paste-mixing type eugenol-free cements revealed comparable retentive force after 28 days of storage. The powder-liquid type cements showed a positive correlation (p<0.05) between the retentive force and the shear strength, while a negative correlation (p<0.05) was obtained for paste-mixing type cement between the retentive force and compressive strength. Mechanical strength of temporary cements could not be a prominent predicting factor for retention of the crowns on the abutments.

“…Numerosos autores han informado que predecir con certeza el comportamiento de los procedimientos de rehabilitación con prótesis fija y coronas individuales es difícil de realizar, puesto que existe un número limitado de estudios longitudinales al respecto (6)(7)(8)(9). Además, sustentan que muchos de éstos estudios se han realizado con desventajas metodológicas y algunos no se han llevado a cabo con grupos aleatorios.…”

RESUMEN. Antecedentes: Innumerables complicaciones hacen que una prótesis parcial fija (PPF) o corona individual fracasen. Por tal razón, se requiere evaluarlas permanentemente, principalmente en los ámbitos donde se forman los profesionales en odontología. Objetivo: Evaluar biológica, mecánica y funcionalmente las PPF colocadas en un servicio odontológico de pregrado en Manizales, Colombia. Métodos: Este estudio descriptivo evaluó 44 prótesis fijas realizadas en 23 pacientes. Los antecedentes se tomaron de la historia clínica. Se valoraron criterios clínicos biológicos, mecánicos y funcionales a través de montajes en un articulador semiajustable. Se realizó una clasificación protésica como tratamientos exitosos, tratamientos con complicaciones reversibles y con complicaciones irreversibles. Resultados: 36 prótesis cumplieron parámetros de supervivencia protésica, entre los cuales complicaciones reversibles relacionadas con alteraciones de los tejidos periodontales y alteración de los contactos interoclusales se identificaron en 20 prótesis. 8 prótesis presentaban complicaciones irreversibles afectadas por severos problemas periodontales y desadaptaciones marginales. No se observaron alteraciones pulpares y ni fracturas dentales o protésicas. Conclusión: La mayoría de las PPF (81,8 %) mostraron parámetros de supervivencia protésica con algunas complicaciones reversibles. Entre los factores identificados que se deben enfatizar en la formación de los estudiantes de odontología al hacer prótesis están el compromiso del paciente con el tratamiento, la higiene oral y el mantenimiento clínico. Ellos son necesarios para garantizar la longevidad de las restauraciones, teniendo en cuenta que el riesgo de complicaciones se incrementa con el tiempo.ABSTRACT. Background: Innumerable complications may cause a fixed partial prosthesis (FPP) or single crown to fail. Therefore, it is important following up them, particularly in those spaces where dental professionals are trained. Purpose: To conduct a biological, mechanical, and functional evaluation of FPPs cemented at a predoctoral dental clinic in Manizales, Colombia. Methods: This descriptive study evaluated 44 FPPs made in 23 patients. Medical information was obtained from patients’ clinical records. Biological, mechanical, and functional criteria were evaluated through analysis of mounted models in semi-adjustable articulators. Decision criteria were: successful treatments, treatments with reversible complications, and treatments with irreversible complications. Results: 36 prostheses met prosthetic survival parameters of which 20 presented reversible complications consisting of alterations of periodontal tissues and interocclusal contacts. 8 prostheses showed irreversible complications, which were caused by severe periodontal problems and marginal discrepancies. Neither pulpal alterations nor dental or prosthetic fractures were observed. Conclusion: Most FPP (81.8 %) met prosthetic survival parameters with some reversible complications. Factors identified that should be emphasized while training dental students in fixed prosthodontics include: patient compliance with treatment recommendation, dental hygiene, and maintenance follow-ups. They are necessary to guarantee lasting results if considering that risk of complications increases with time.
