The Esthetic and Psychologic Benefits of an Intraoperative Provisional Restoration.

OBJECTIVE: When multiple visible teeth are prepared, the prolonged treatment time may lead to patients needing a break that requires them to leave the operatory. Such a situation allows the patient to view their prepared teeth, a process that can be disconcerting to some patients. CLINICAL CONSIDERATIONS: An intraoperative provisional restoration can be made by using a thermoplastic vacuum-formed matrix of the patient's teeth that is filled with white-colored impression material and then placed over the prepared teeth to form a provisional restoration. CONCLUSIONS: The use of an intraoperative provisional restoration can be effectively used to cover prepared teeth while providing normal tooth morphology and facial appearance after preparation of visible teeth. CLINICAL SIGNIFICANCE: When visible teeth are prepared, an intraoperative provisional restoration can be used to cover the prepared teeth and prevent concerned patients from viewing their prepared teeth.

[Gingival displacement techniques in daily practice. Survey among dental surgeons in Abidjan, Ivory Coast]. / Réalisation des techniques d'ouverture sulculaire en pratique quotidienne. Enquête faite auprès des chirurgiens-dentistes d'Abidjan, Côte d'Ivoire.

INTRODUCTION: Access to cervical margins allows the practitioner to record the entire cervical margin in order to provide a true copy to the technician. This requires a gingival displacement obtainable by different techniques. This study aimed to assess the implementation of gingival displacement methods prior to impression taking in fixed prosthodontics. MATERIALS AND METHODS: This is a descriptive and cross-sectional survey of sample of 71 dentists practising in Abidjan, Ivory Coast; which ran from October 2nd, 2010 to November 14th, 2010. A survey form was administered to dentists. The questionnaire was organised around the following headings: identification of dentists and practice of gingival displacement methods. The data processing done using software Epi Info 6 and Excel XP on Window XP, allowed calculation of frequencies, means and proportions and the establishment of connection between variables with the chi2 test. The significance level was set at p < 0.05. RESULTS: The results of the survey indicate that non-surgical methods of gingival displacement, including retraction cords and temporary crowns are those they use most frequently (76.4%) because the vast majority of practitioners (87.22%) believe the most traumatic to the periodontium are surgical methods. CONCLUSION: Our study showed that the gingival displacement methods are frequently carried out in daily practice, regardless of the topography of the abutment teeth and their number, but with a preference for non-surgical methods, particularly those using retraction cords and temporary crowns. The use of injectable gingival displacement paste is not harmful to the periodontal tissues, easy to use and have a very efficient haemostatic action. It should also be known and practiced.

Can virtual nature improve patient experiences and memories of dental treatment? A study protocol for a randomized controlled trial.

BACKGROUND: Dental anxiety and anxiety-related avoidance of dental care create significant problems for patients and the dental profession. Distraction interventions are used in daily medical practice to help patients cope with unpleasant procedures. There is evidence that exposure to natural scenery is beneficial for patients and that the use of virtual reality (VR) distraction is more effective than other distraction interventions, such as watching television. The main aim of this randomized controlled trial is to determine whether the use of VR during dental treatment can improve the overall dental experience and recollections of treatment for patients, breaking the negative cycle of memories of anxiety leading to further anxiety, and avoidance of future dental appointments. Additionally, the aim is to test whether VR benefits dental patients with all levels of dental anxiety or whether it could be especially beneficial for patients suffering from higher levels of dental anxiety. The third aim is to test whether the content of the VR distraction can make a difference for its effectiveness by comparing two types of virtual environments, a natural environment and an urban environment. METHODS/DESIGN: The effectiveness of VR distraction will be examined in patients 18 years or older who are scheduled to undergo dental treatment for fillings and/or extractions, with a maximum length of 30 minutes. Patients will be randomly allocated into one of three groups. The first group will be exposed to a VR of a natural environment. The second group will be exposed to a VR of an urban environment. A third group consists of patients who receive standard care (control group). Primary outcomes relate to patients' memories of the dental treatment one week after treatment: (a) remembered pain, (b) intrusive thoughts and (c) vividness of memories. Other measures of interest are the dental experience, the treatment experience and the VR experience. TRIAL REGISTRATION: Current Controlled Trials ISRCTN41442806.

Percepção de responsáveis sobre medo odontológico e técnica alternativa para remoção de cárie / The caregivers’ perception of dental fear and alternative technique for caries removal

O objetivo deste estudo foi avaliar a percepção de responsáveis sobre os fatores preditores de medo odontológico infantil e aceitação de uma técnica alternativa (abrasão ultrassônica) para a remoção de cárie. Cento e sessenta e dois responsáveis por crianças atendidas em uma instituição pública responderam a um questionário semiestruturado. A média de idade das crianças foi de 9 anos, sendo 52,5% meninos. Resultados mostraram que, gostavam de ir ao dentista 73,5% e 34% apresentavam-se nervosas/ansiosas antes de serem atendidas. A maioria dos responsáveis julgou importante a realização de estudos para descoberta de novos métodos para substituição do motor (p> 0,05) e autorizariam a utilização da abrasão ultrassônica (p > 0,05). Conclui-se que, aproximadamente, metade das crianças tinha medo ou ficavam ansiosas durante o atendimento, e que os responsáveis são receptivos à utilização de técnicas alternativas de remoção de cárie.

Esthetic potential of single-implant provisional restorations: selection criteria of available alternatives.

UNLABELLED: Provisional implant restorations are essential tools used to optimize the esthetic outcomes for single-tooth implant restorations. This article describes three groups of available alternatives and the specific options within each group including removable prostheses (interim removable partial denture, vacuum-formed appliance), tooth-supported prostheses (bonded extracted or denture teeth, cast metal or fiber-reinforced resin-bonded fixed partial denture [FPD], wire-retained resin-bonded FPD, acrylic resin provisional FPD), and implant-supported fixed prostheses (implant-retained provisional restoration). Advantages and disadvantages as well as fabrication guidelines for each option are provided. The author proposes that the restorative dentist consider eight criteria in selecting the most appropriate type of provisional prosthesis for a specific patient situation including the esthetic potential, patient comfort, treatment time, laboratory cost, occlusal clearance, ease of removal, durability, and ease of modification. The patient's esthetic expectations are critical in determining the most suitable type of provisional restoration. Esthetically pleasing provisional restorations are part of the evolving implant continuum, making implant dentistry more appealing to practicing dentists and potential patients. CLINICAL SIGNIFICANCE: Provisional restorations for single implants have evolved from temporary expedients during osseous and soft tissue integration to critical therapeutic tools used to assess patient expectations, communicate with the laboratory, and optimize definitive implant treatment. The selection of the type of provisional restoration may significantly influence esthetics during the period of implant integration and soft tissue healing. However, it is unlikely that there is a direct correlation between the type of provisional restoration used and the esthetic outcome of the definitive prosthesis.

Predictable provisionalization: achieving psychological satisfaction, form, and function.

UNLABELLED: The dentition is the foundation of the human face and is far more than just a masticatory apparatus. The smile, which is the definition of humankind, crosses all gender, age, cultural, and religious boundaries to express emotion. When enhancing or restoring a smile with aesthetic dentistry, the provisionalization phase is critical in conveying information regarding function, occlusion, phonetics, and the patient's expectations among the members of the restorative team. This presentation details a predictable process for rapidly fabricating provisional restorations with optimal fit and performance. LEARNING OBJECTIVES: This article describes the role of provisionalization and a protocol for fabrication of temporary prostheses for optimal results. Upon reading this article, the reader should: Understand the role of provisionalization on the surrounding soft and hard tissue structures. Recognize the role provisionalization plays in patient education and communication.
