In six consecutive patients planned to receive combined orthodontic-orthognathic surgery natural tooth color on 8 incisors was measured before initiation of the combined treatment (Time Point 1- baseline) and after its completion (Time Point 2- after intervention). The statistical interpretation of the results showed that tooth color change in the surgical group was higher in comparison to control groups. Control group I included non treatment subjects, while control group II included standard orthodontic treatment subjects. The results indicated that orthognathic surgery may affect natural tooth color but to small degree, as the color differences were just bellow the threshold value of 3.7 ΔΕ units. Under this value a color change cannot be easily detected by a human eye.
A multicenter prospective observational study in which aim is to illustrate the clinical outcome of dental implants "Kontact N"; and the effects of its nanostructured surface on the osseointegration and secondary stability without increasing the rate of peri-implantitis. All the enrolled patients will be eligible for one or multiple implant-supported fixed restoration(s) according to the routine clinical practice and the manufacturer's instruction for use.
1. Plaque level in subjects using the Modified Circular method is different from that in subjects using natural tooth brushing method. 2. Gingivitis level in subjects using the Modified Circular method is different from that in subjects using natural tooth brushing method. 3. Level of plaque after using the Modified Circular method is different from that before using the method. 4. Level of gingivitis after using the Modified Circular method is different from that before using the method.
This is a randomized clinical trial designed to assess the 1-year effectiveness of two treatment modalities for the mandibular edentulists: conventional complete dentures and single-implant mandibular overdenture.
The result of the study will demonstrate that the functional activity of maxillofacial area with edentulous posterior bounded spaces recovers more effectively in patients treated with restorations on implants comparing to patients treated with fixed dentures.
The objective of this explanatory mixed methods study is to compare a novel attachment system (Novaloc) to a traditional alternative (Locator) for single implants in the mandible of edentate elders. The investigators will carry out a randomized cross-over clinical trial comparing Novaloc attachments to Locators for single-implant mandibular overdentures in edentate elders. Participants will be followed for three months with each attachment type; patient-based, clinical and economic outcomes will be gathered. A sample of 26 participants is estimated to be required to detect clinically relevant differences in terms of the primary outcome (patient ratings of general satisfaction). Participants will choose which attachment they wish to keep, then be interviewed about their experiences and preferences with a single implant prosthesis and with the 2 attachments. Data from the quantitative and qualitative assessments will be integrated through a mixed-methods explanatory strategy. A last quantitative assessment will take place after 12 months with preferred attachment; this latter assessment will enable the observation of attachments' long-term wear and maintenance events.
The aim of this study is to assess the cost-effectiveness of the mandibular overdenture retained by one and two implants and the mandibular fixed prosthesis retained by four implants, based on a randomized clinical trial.
Dental implants are often the preferred treatment option and in some clinical scenarios they are considered the standard of care to restore missing or damaged teeth, due to the limitations of conventional treatments. For fully edentulous subjects, conventional tissue-supported dentures in some cases are associated with severe subjective complaints and difficult adaptation, mainly the mandibular denture, resulting in limited function and detrimental effects on oral health-related quality of life, especially for older patients. The use of implants to retain a mandibular denture (overdenture) has been recommended as a suitable and low-cost alternative to improve denture stability, with positive effects on oral comfort and function. The two-implant mandibular overdenture has been considered an effective design to achieve clinical benefits for patients. However, the main problem facing two-implant overdenture is the high cost of implantation and the relative complexity of the surgical intervention, so the use of a single midline implant to retain a mandibular overdenture was suggested as a more viable solution for reducing costs and complexity of treatment with similar benefits compared to solutions with higher number of implants. Nevertheless, there are few studies that compared the performance of different retention systems and their effects on patient-centered outcomes, such as satisfaction with the dentures, oral health-related quality of life, individual preferences and other subjective ratings of clinical outcomes. Thus, the aim of this randomized clinical trial with a crossover design is to investigate the changes in clinical and patient-reported outcomes following the use of different retention systems for a single implant-retained mandibular overdenture Hypothesis: it was hypothesized that clinical and patient-reported outcomes of a single-implant mandibular overdenture is dependent on the type of retention system, and patients have distinct preferences in relation to different attachments
Prospective, single cohort, multi-center study evaluating the TREFOIL concept for the treatment of edentulous or patients with failing mandibular dentition over 5 years. 90 patients (15 per centre) will be included. The subject population is at least 18 years old, in need of an implant restored full prosthesis providing sufficient bone in the interforaminal where a fixed restoration on three implants is regarded as an appropriate treatment solution. The components are TREFOIL treatment concept (implants and framework).
