Immediate Postextraction Screw-Retained Partial and Full-Arch Rehabilitation: A 3-Year Follow-up Retrospective Clinical Study.

The aim of this study was to document the performance of a novel technique (OnlyOne), involving immediate restoration of postextraction implants supporting a partial or full-arch restoration. A retrospective analysis of patients with at least 3 years of follow-up was performed. Implants were tilted mesiodistally and vestibulopalatally according to the available bone. Prosthetically guided definitive abutments were connected at surgery and never disconnected. Anorganic bovine bone grafting was done to preserve the buccal bone and the ridge contour. Patients received a screw-retained provisional prosthesis within 24 hours of surgery and a final screw-retained prosthesis within 1 year. Prostheses emerged from natural soft tissue. Clinical and radiographic evaluation was routinely performed. A total of 70 patients received 153 implants in fresh extraction sockets. The mean follow-up was 38.0 ± 3.0 months (range 36 to 51 months). One implant failed at the 3-year follow-up. Implant survival was 99.3%. Marginal bone level change averaged -0.68 ± 1.2 mm at the last radiographic control. Immediate placement and restoration of implants designed for high primary stability with a definitive abutment placed at surgery and final screw-retained prosthesis with no artificial gingiva is a viable procedure with excellent medium-term outcomes.

Immediate occluding definitive partial fixed prosthesis versus non-occluding provisional restorations - 4-month post-loading results from a pragmatic multicenter randomised controlled trial.

PURPOSE: To compare the clinical outcome of dental implants restored with definitive occluding partial fixed prostheses within 1 week, after implant placement with immediate non-occluding provisional restorations, which were to be replaced by definitive prostheses after 4 months. MATERIALS AND METHODS: Fifty partially edentulous patients treated with one to three dental implants, at least 8.5 mm long and 4.0 mm wide inserted with a torque of at least 35 Ncm, were randomised in two groups of 25 patients each, to be immediately loaded with partial fixed prostheses. Patients of one group received one definitive screw-retained metal-ceramic prosthesis in occlusion within 1 week after placement. Patients of the other group received one non-occluding provisional acrylic reinforced prosthesis within 24 h after implant placement. Provisional prostheses were replaced after 4 months by definitive ones. The follow-up for all patients was 4-months post-loading. Outcome measures were prosthesis and implant failures, any complications, peri-implant marginal bone level changes, aesthetic evaluation by a clinician, patient satisfaction, chair time and number of visits at the dental office from implant placement to delivery of definitive restorations. RESULTS: No patient dropped out. Two immediately occlusally loaded implants with their related definitive prostheses (8%) failed early (difference in proportions = 0.08; 95% CI: -0.03 to 0.19; P = 0.490). Four complications occurred in the occlusal group versus one in the non-occlusal group; (difference in proportions = 0.12; 95% CI: -0.04 to 0.28; P = 0.349). Four months after loading, patients subjected to non-occlusal loading lost an average of 0.72 mm of peri-implant bone versus 0.99 mm of patients restored with occluding definitive partial fixed prostheses. There were no statistically significant differences for marginal bone level changes between the two groups (mean difference = -0.27 mm; 95% CI: -0.84 to 0.30; P = 0.349). The differences for aesthetic scores showed no statistical significance (8.26 versus 7.58; P = 0.445); the same was seen for aesthetics evaluated by patients (Mann-Whitney U test: P = 0.618). Patients in the non-occlusal group were significantly more satisfied with the function of their implant-supported prostheses (Mann-Whitney U test: P = 0.039). Significantly less chair time (mean difference = -28.4 min; 95% CI: -48.82 to -7.99; P = 0.007) and the number of visits (mean difference = -1.88; 95% CI: -2.43 to -1.33; P < 0.001) were required for the immediate definitive prosthesis group. CONCLUSION: This study did not provide a conclusive answer but may suggest that provisional prostheses non-occlusally immediately loaded may increase patient functional satisfaction, chair time and the number of visits, with respect to definitive prostheses immediately loaded in functional occlusion.

[Transient removable dentures]. / Les prothèses amovibles transitoires.

Removable dentures are always transient current. The epidemiology and causes of tooth gaps demonstrate the need to master the different prosthetic treatment. This made whether to propose treatment plans that take into account psychological, physiological and technical support for this patient. Different situations may arise. A gradual transition may be considered or immediate passage to the total edentulous according to general criteria, local and desiderata of patients. After tooth extraction, the transitional prosthesis can control bone lysis thereby it is part of a complete treatment before prosthesis. It also facilitates a good psychological and physiological integration before the prosthesis use.

Immediate rehabilitation of the posterior maxilla with extensive sinus pneumatization with one axial and one trans-sinus tilted implant: a 3-year clinical report and a classification.

Implant rehabilitation of the posterior maxilla can entail difficulties due to reduced bone quantity and poor bone quality, especially after long-term edentulism. In some patients, multiple surgeries are necessary, which may lead to higher patient morbidity and longer treatment times before a prosthetic rehabilitation can be achieved. This article presents an immediate fixed prosthesis in a posterior atrophic maxilla supported by 1 anterior axial implant and 1 posterior tilted fixture placed with an intrasinus insertion. Additionally, a classification scheme for immediate treatment for the posterior maxilla based on the available residual bone is provided.

Rehabilitación protésica inmediata por fracaso de un reimplante dentario: presentación de un caso / Immediate prosthetic rehabilitation because of failure of a dental reimplantation: a case presentation

FUNDAMENTO: la avulsión dentaria es la salida completa del diente de su alveolo, el mejor tratamiento para un niño es la reimplantación de su propio diente, pero la terapéutica ofrece grandes retos al profesional que dependen de múltiples factores. OBJETIVO: demostrar que la rehabilitación por prótesis inmediata, es una alternativa ante el fracaso de un reimplante dentario. CASO CLÍNICO: paciente masculino, de doce años de edad, que acudió con su padre a la consulta de prótesis estomatológica del Policlínico de atención a combatientes de los servicios médicos del MININT de Camagüey, porque hace dos años y medio le fue reimplantado el diente antero superior derecho al recibir un golpe en la cabeza que le provocó la salida del mismo de su alveolo y entonces presentó signos y síntomas característicos de una evolución desfavorable. CONCLUSIÓN: se comprobó la existencia de una reabsorción radicular inflamatoria avanzada, asociada a otros factores como: prolongado tiempo extraoral del diente reimplantado, deficiente medio de conservación, inadecuado tipo y tiempo de ferulización y el tórpido manejo endodóntico. La rehabilitación protésica inmediata fue el tratamiento adecuado para restablecer los parámetros psíquicos, estéticos y funcionales demandados por el paciente.

BACKGROUND: dental avulsion is the complete loss of a tooth from its alveolus; the best treatment for a child is the reimplantation of the own tooth but the therapeutics presents great challenges for the professionals that depend on many factors. OBJECTIVE: to demonstrate that the rehabilitation by means of immediate prosthesis is an alternative to the failure of a dental reimplantation. CLINICAL CASE: a twelve-year-old male patient that came with his father to the stomatological consultation of prosthesis of the policlinic for veterans of the medical service of the Ministry of Internal Affairs of Camagüey. Two and a half years ago, the patient underwent the reimplantation of the right anterosuperior tooth after receiving a blow to the head that caused the loss from the alveolus; then, the patient presented signs and symptoms characteristic of an unfavourable progress. CONCLUSIONS: the existence of an advanced inflammatory radicular reabsorption was confirmed, associated to other factors like: a prolonged extraoral time of the reimplanted tooth, a deficient conservation medium, inadequate type and time of splinting and the torpid endodontic handling. The immediate prosthetic rehabilitation was the suitable treatment to re-establish the psychic, aesthetic, and functional parameters required by the patient.

Transition from failing dentition to full-arch fixed implant-supported prosthesis with a staged approach using removable partial dentures: a case series.

The present retrospective case series is aimed at evaluating a staged approach using a removable partial denture (RPD) as an interim prosthesis in treatment to correct a failing dentition until such time as a full-arch fixed implant-supported prosthesis may be inserted. Eight patients, who had undergone maxillary full-arch rehabilitation with dental implants due to poor prognosis of their dentitions, were analyzed. All treatment included initial periodontal therapy and a strategic order of extraction of hopeless teeth. An RPD supported by selected teeth rehabilitated the compromised arch during implant osseointegration. These remaining teeth were extracted prior to definitive prosthesis delivery. Advantages and drawbacks of this technique were also recorded for the cases presented. Among the advantages provided by the staged approach are simplicity of fabrication, low cost, and ease of insertion. Additionally, RPD tooth support prevented contact between the interim prosthesis and healing abutments, promoting implant osseointegration. The main drawbacks were interference with speech and limited esthetic results. Implant survival rate was 100% within a follow-up of at least 1 year. The use of RPDs as interim prostheses allowed for the accomplishment of the analyzed rehabilitation treatments. It is a simple treatment alternative for patients with a low smile line.

A simple technique for replacing extracted anterior teeth using a vacuum formed retainer.

This technique can be used as an immeciate short-term solution after extraction, implant placement or grafting procedures. Long-term use is not appropriate and it is not suitable where there is poor hygiene or a high smile line where the junction of the flange and soft tissue would be conspicuous. This device is easily removed to facilitate hygiene, it is available almost immediately, is inexpensive, comfortable to wear, conservative of abutment teeth and can be relieved of soft tissue contact. It is not appropriate in situations where occlusal units are required, where multiple teeth are to be extracted, where there are high aesthetic demands or when a long-term solution is required.

Preoperative gingival conditioning as a guide for implant installation and to achieve proper dentogingival contours.

A successful esthetic outcome for implant-supported dentures depends on the careful manipulation of peri-implant tissue as well as the precise placement of the implant. In addition, careful surgical and prosthetic planning is essential for esthetically important areas, especially in partially edentulous cases. This study describes a clinical case that presented absent maxillary central incisors in which prior prosthetic planning was used to perform provisional restorations, that was used to condition the gingival tissues and guide implant installation. These procedures made it possible to achieve a dentogingival contour, interdental papillae, and an emergence profile in the edentulous area. The techniques outlined here proved to be sufficient and support the peri-implant tissues to create a more esthetic final prosthesis.

This report describes the use of a multipurpose template stabilized with existing implants to provide accurate information for immediate implant placement, to facilitate impression making, and to record maxillomandibular relationships for the fabrication of an interim immediate implant-supported fixed prosthesis.

Implante inmediato: ¿mito o realidad? / Immediate implant: myth or reality?

El protocolo de colocación inmediata de implantes post exodoncia, introducido en la década de los 90, fue descrito y propuesto como un gran aporte a la implantología contemporánea. Entre sus principales indicaciones se destacaban la necesidad de preserva el tejido duro y blando, previniendo así la pérdida ósea de la apófisis alveolar. Si bien estudios prospectivos y retrospectivos han mostrado tasas aceptables de supervivencia de implantes instalados bajo este protocolo, reciente revisiones sistematizadas randomizadas con alto cumplimineto de los niveles de evidencia, demuestran con claridad y significancia que este protocolo se asocia a un mayor riesgo de complicaciones estéticas y compromiso de la predictibilidad de la osteointegración. El objetivo del presente artículo es exponer de manera resumida, sobre la base de la evidencia científica actualmente disponible y de la descripción de un caso clínico, antecedentes que permitan aclarar ciertos mitos y controversias de un tema de gran actualidad y permanente discusión en los más importantes foros académicos, proporcionando al clínico elementos adicionales en la toma de decisiones. No obstante lo anterior, sobre la base de la evidenciay experiencia clínica documentada, resultaría razonable concluir que el implante inmediato no prevendría la pérdida ósea vertical ni horizontal y que su indicación, así como los resultados en el corto, mediano y largo plazo, serían fenómeno multifactorial que estaría fuertemente determinado, entre otros, por el biotipo periodontal, grosor de la tabla vestibular, posición del implante, manejo del gap, hábito tabáquico, enfermedad periodontal, trauma quirúrgico, presencia y características de un defecto óseo en la zona a implantar.

Fabricating an interim immediate partial denture in one appointment (modified jiffy denture). A clinical report.

Its advantages include maintenance of a patient's appearance, muscle tone, facial height, tongue size, and normal speech and reduction of postoperative pain. The purpose of this study is to describe the use of a patient's fixed prosthesis for fabricating an interim immediate partial denture in one appointment. Occlusion, occlusal vertical dimension, and facial support are maintained during the healing period in this procedure.

Avaliação da estabilidade do implante pela análise da frequência de ressonância: estudo in vivo com carregamento imediato e precoce em um modelo em cães / Evaluation of implant stability by means of resonance frequency analysis: an in vivo study with immediate and early loading in the dog model

Este estudo teve por objetivo avaliar a estabilidade de implantes de carga imediata ou precoce, em diferentes intervalos de tempo. Material e Métodos: foram extraídos os pré-molares mandibulares, bilateralmente, de oito cães e, após 12 semanas, cada cão recebeu seis implantes (três em cada lado da mandíbula). A carga foi aplicada em pares, em um implante de cada lado, sendo que o primeiro par recebeu carga imediata, o segundo par após sete dias, e o terceiro par após 14 dias. Em cada período, as medidas de estabilidade dos implantes foram realizadas por frequência de ressonância (ISQ). Após 12 semanas, uma nova leitura da estabilidade dos implantes foi realizada. A análise estatística foi feita usando modelo linear de efeitos mistos, que é uma generalização do modelo linear padrão (Anova). Diferenças foram consideradas significantes quando p < 0,05. Resultados: a estabilidade do implante mudou no decorrer do tempo para todos os protocolos de carga, apresentando aumento significativo na estabilidade final, mas as variações foram semelhantes para os três grupos estudados. Nos períodos de sete dias e 14 semanas, o protocolo de carga imediata apresentou menor estabilidade de implante do que os protocolos de sete e 14 dias. Conclusão: a estabilidade do implante diminui nos períodos iniciais após a cirurgia e aumenta no período de 14 semanas. A estabilidade dos implantes do protocolo de carga imediata é menor do que a dos protocolos de sete e 14 dias, sugerindo cautela para seu uso...

This study aimed to evaluate implant stability in function with immediate or early loading protocols at different time intervals. Material and Methods: The mandibular premolars of eight dogs were pulled bilaterally. After 12 weeks, each dog received 6 implants (3 at each mandibular side). Implant loading was performed for each implant pair according to the following periods: immediate (fi rst pair), 7 days later (second pair), 14 days later (third pair). Implant stability measurements were performed by means of resonance frequency for each period. After 12 weeks, new readings of implant stability were obtained. The statistical analysis was performed using a mixed linear model, which is a generalization of the standard linear model (Anova), with differences considered signifi cant at p<0.05. Results: Implant stability changed throughout time for all loading protocols, presenting a significant increase in fi nal stability values, but variations were similar for the three studied groups. At 7- and 14-week periods, immediate loading protocol presented lower implant stability than 7-day or 14-day protocols. Conclusions: Implant stability diminishes in the initial periods after surgery, and increases in a 14-week period. In the middle-term, there were no statistically significant differences in the stability of immediately-loaded implants, one or two weeks after implant placement...

The success rate of narrow body implants used for supporting immediate provisional restorations: a pilot feasibility study.

BACKGROUND: Implants were first designed to be used in the reconstruction of edentulous mandibles. However, with the technological advancement, enormous changes were made to improve the implant design and surface characteristics leading to the wide use of implants in the replacement of missing teeth. During the transition from an edentulous span to a fixed prosthesis, narrow body implants (NBIs) have been proposed to enhance patient comfort and function. Therefore, this study was aimed at investigating the survival and success rates of NBIs used for supporting immediately nonfunctional loaded provisional fixed partial denture (PFPD). METHODS: Either 2.2- or 2.4-mm-diameter dental implants were placed transmucosally into the edentulous ridges of 10 partially edentulous patients. PFPD of self-cured bis-acryl composite material were made using either a vacuform template chairside or a relined prefabricated PFPD. Occlusal adjustments were made to ensure that there was no functional loading on the provisional restorations before they were secured onto the transitional implants. RESULTS: At 1 year, the implant success and survival rates were 38.7% and 93.5%, respectively, with a mean percentage of bone loss of 9.46% (0%-40%) and a mean bone loss of 1.19 mm (range: 0-3.5 mm). CONCLUSIONS: With a favorable implant survival rate, the use of NBIs to support provisional restorations seemed to be a feasible treatment option. In addition, there is merit for research on the long-term use of NBIs-supported final prostheses.
