Filter by:The aim of this study is to assess the influence of this particular treatment method on the patients' quality of life and masticatory function.
The aim of this study is to evaluate the effect of abutment macro-design on soft and hard tissue responses. This trial is designed as a randomized controlled clinical study in which two groups of fourteen partially edentulous patients will have as part of their treatment one implant placed in the maxillary premolar region.
Purpose: To compare complete denture outcomes between conventional and digital denture fabrication processes. Participants: Sixteen edentulous adult patients in the University of North Carolina School of Dentistry Student Clinic who are seeking removable complete dentures. Procedures (methods): Two complete sets of dentures will be fabricated for each subject: one using the conventional process (A) and the other using a digital process (B). Variability will be assessed by the research team, the treating dental students, an independent prosthodontist, and the patients through quantitative measures. Case selection and results analysis will be evaluated with recognition of the Prosthodontic Diagnostic Index.
The primary objective of the present study is to evaluate the marginal bone level changes occurring in total edentulous patients treated with six or four implants. Secondary objective - overall survival rate - soft tissue status by assessment of bleeding on probing (BoP) and probing pocket depth (PPD) at baseline and after 1,3,5 years - prosthetic survival rates including screw or abutment loosening, framework or veneer fractures
The objective of the present study is to evaluate if loss of multiple adjacent teeth will cause proportionally greater tissue diminution than the loss of single teeth the possibility of counteracting unfavourable ridge modeling after multiple tooth extractions by placing implants in the fresh extraction sites soft tissue alterations at implants and adjacent teeth
Purpose: The goal of guided bone augmentation is to provide an alveolar ridge of sufficient dimension to permit dental implant placement. While a wide variety of bone graft and barrier membrane products are commercially available, limited evidence exists supporting the use of one technique over another. The purpose of this study is to radiographically define the dimensional bone changes following horizontal bone augmentation using a synthetic GUIDOR® (Sunstar, Inc.) membrane. Secondary outcome measurements will include the assessment of inflammation, infection, or other wound healing complications. Participants: A total of 60 patients requiring bone augmentation of a single bound edentulous site prior to dental implant placement will be selected for this study. This is a multicenter study with 30 patients receiving treatment at each study site. Procedures (methods): Patients will be randomly allocated to receive horizontal bone augmentation with synthetic GUIDOR® membrane + freeze dried bone augmentation (FDBA), synthetic GUIDOR® membrane alone, or xenograft BioGide® membrane + FDBA. Cone beam computed tomography (CBCT) imaging will be obtained at baseline and 6 months post-operatively to assess dimensional alveolar ridge changes. Additionally, post-operative appointments at 1, 2, and 4 weeks post-grafting will be completed to assess the presence of inflammation, infection, wound dehiscence, or membrane exposure.
1. Hypothesis/Specific aims The aim of the present study proposal is to validate an implant treatment concept in the edentulous upper maxilla using four implants-supported locators abutments to retain removable prosthesis. Specific aims: - The primary objective of the study is to evaluate the implant and prosthodontics success rates of the proposed implant treatment approach after a follow-up period of 1, 3 and 5 years as well as the biological and prosthodontics complications. - The secondary objective is to assess the evolution of patient centered outcomes with the suggested treatment in the maxilla. Oral health-related quality of life (OHRQoL) and patients' satisfaction relating to their prostheses will be considered. - The third objective will be to compare the implant, prosthodontics and patient-centered outcomes according to the implant distribution; 4 anterior to maxillary sinus (ANT) versus 2 anterior implants and 2 implants in the maxillary tuberosity (POST). Hypothesis: - Implant survival rate using this treatment concept is similar to restoration with implant-supported fixed prosthesis, based on published data. No difference of implant survival rates is found between ANT and POST implant distribution. - Prosthodontics survival rate using the following treatment concept is similar to the ones found with a bar, based on published data. The ANT implant distribution causes fewer prosthodontics complications compared to the POST implant distribution. - There is a significant improvement in OHRQoL and patient satisfaction compared to the baseline OHRQoL observed with a conventional removable denture. The levels of improvement OHRQoL and patient satisfaction are similar for ANT and POST implant distributions.
BACKGROUND: The literature has shown that simplified methods for complete denture fabrication can be as effective as the traditional techniques, but with less expenditure of time and resources, without prejudice to the patients. However, the effectiveness of these simplified methods for patients with more complex medical conditions haven't been deeply explored. OBJECTIVES: To evaluate the effectiveness of a proposed simplified method for complete dentures fabrication for patients with severely resorbed mandibular alveolar bones. METHOD: edentulous patients requesting treatment with bimaxillary complete dentures in a university clinic will be rehabilitated following a simplified technical proposal, being divided randomly into two groups according to the mandibular arch molding technique. In group A, a single impression with alginate through pre-fabricated trays will be performed, while patients allocated in group B will receive a second molding with a more complex technique. After 3 and 6 months, besides important clinical parameters, it will be investigated aspects related to patient's perceptions about the success of treatment. The study will be conducted with a minimum of 30 participants per group, and comparisons between the two groups will be made by means of tests suitable for distribution of data.
With an aging population a prevalence of edentulous patients increased above 60 % among individuals aged ≥65 yr. Face mask ventilation of these edentulous patients is often difficult because of the inadequate fitting of the standard mask to the face. In addition, because of a reduction in muscle tone under general anesthesia, the air space in the oropharynx is reduced, and posterior displacement of the tongue, soft palate and epiglottis tend to close the airway. The laryngeal mask airway (LMA) provides a better alternative to the standard face mask if the facial contours of the patient are not suited to the standard face mask. It is more difficult to perform bag-mask ventilation in edentulous patients than in patients with intact dentition. The laryngeal mask airway (LMA) provides a better alternative to the standard face mask if the facial contours of the patient are not suited to the standard face mask. We aimed to compare the routinely used laryngeal mask airway in our clinic, the LMA Unique™ with the newly released LMA Supreme™ in edentulous elderly patients for the success in first attempt insertion, ease and time of insertion, and oropharyngeal leak pressure.
