The aim of this study is to gather clinical data related to the use of Plastalgin and Plastalgin Fast, in order to comply with the new medical device regulation. The target population for this study is the same as the intended population specified in the study device's instructions for use: children from 5 years old and adults. Collection, recording, and reporting of data will be accurate and will ensure the privacy, health, and welfare of participating patients during and after the study
Since the teeth loss leads to disability & impairment, and teeth restoration lead to improvement in the life quality throughout the oral health improvement. The acceptable function of a complete denture on great extent depends on impression technique which includes the maximum coverage of denture supporting areas and making a combination of managing movable soft tissues along with different kinds of impression materials and techniques for accurate reproduction of oral foundation. Border molding considered to be as an important step in the in complete denture fabrication, since the retention of complete dentures depend on several factors, as the biological, physical and mechanical, these factors could be achieved by mean of an accurate border molding followed by an accurate final impression. The border molding technique is the shaping of the border areas of a custom impression tray by manual or functional manipulation of the tissue adjacent to the borders in order to duplicate the size and contour of the vestibule resulting in maintains of the peripheral seal during function. This property causes the border molding process to require twenty-four insertions, namely eight in the maxilla and sixteen in the mandible causing long working time and discomfort in patients. Hence, the material used for this technique should provide optimum working time, have adequate body, and permit the correction of border moulding by additions. However additions if made to a single step border moulded material would again introduce all the disadvantages that are associated with sectional moulding Single-step border molding is considerably more straightforward than sectional border molding owing to the reduced number of tray insertions. This technique is usually used with elastomeric impression materials, which may not provide sufficient time to mold and record the peripheral tissues of the denture bearing area. The present technique uses light polymerizing tray material for molding tray borders, offering extended working time. This is advantageous for operators with less experience, such as dental school students. Furthermore, correction of border molding is possible with the addition of new material. The technique uses materials that are readily available,and no special armamentarium is required.
This study aims to test the combined effects of different loading protocols and surgical approaches on clinical and patient-reported outcome measures (PROMs) following the use of four mini implants for mandibular overdenture retention. The main study hypotheses are: 1. There are significant improvements in PROMs following implant intervention compared to baseline measures; 2. Immediately loaded mini implants have similar failure rates compared to mini implants receiving a delayed 6-week protocol. 3. Flapless surgery has similar post-insertion outcomes compared to flapped surgery.
A randomized clinical trial (RCT) was designed. Fourteen completely edentulous participants were randomly allocated into two equal groups. All participants received two implants in the inter-foraminal area with ball attachments. Participants in the control group were rehabilitated with conventionally manufactured Polymethyl Methacrylate (PMMA) maxillary complete denture and mandibular implant overdentures while participants in intervention group received digital light processed (DLP)-printed photo-polymerizable PMMA Nextdent maxillary complete denture and mandibular implant overdentures. Follow-up appointments were scheduled at 3,6, and 12 months where data of Oral Health Impact Profile 19(OHIPEDENT19) was used to assess the OHRQoL (oral health related quality of life). In addition, denture retention was measured using digital force gauge device. Data were collected and statistically analyzed.
Fifty six patients were randomly enrolled in the study. Participants were randomly stratified into two control groups and two test groups, from which conventional pick up and digital impressions were made respectively. Patients of group 1 (CIG Axial) and 3 (DIG Axial) received 4 axial implants whereas, group 2 patients (CIG Tilted), and group 4 (DIG Tilted) received two anterior axial implants and two distal tilted implants. All participants received hybrid dentures. Bone loss, implant loss, maintenance of prosthesis were evaluated at 6m,12m, and 24 months follow up period.
A randomized clinical trial (RCT) was designed. The participants were randomly allocated into either of the two groups intervention or control group each of 14 participants. Participants in control group (Group-A) received conventional manufactured implant overdenture while participants in intervention group (Group-B) received CAD-CAM manufactured implant overdenture.
The aim of this study is to assess the cost-effectiveness of the mandibular overdenture retained by one and two implants, based on a randomized clinical trial.
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.
