Filter by: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.
This study aimed to evaluate the oral stereognosis in completely edentulous patients with palatal tori. Oral stereognosis is tested using different test specimens in completely edentulous patients with maxillary tori and completely edentulous patients without maxillary tori.
In this retrospective study, approximately 60 patients treated with 6mm short implants (Straumann, SLA (sandblasted, large-grit, acid-etched surface), SLActive (sandblasted, large-grit, acid-etched, hydrophilic surface), 4.1 or 4.8 mm in diameter) will be followed for 4.5-18.2 years. Clinical and radiographic parameters will be assessed in a follow-up examination.
Purpose: To determine if adjustment of full-arch zirconia frameworks processed on a model obtained with an intraoral scanner and an auxiliary device is not inferior to that of identical frameworks obtained from an elastomeric impression. Materials and methods: Eight consecutive patients ready for a full-arch rehabilitation on already osseointegrated implants were selected. Two sets of impressions were taken, one open tray with polyether and splinted impression copings and a second one with an intraoral scanner. A verification plaster jig was used for the elastomeric impression and a prefabricated auxiliary device was used to adjust the optical intraoral impressions. Two full-zirconia frameworks with the same design were processed and tested on the patient by two independent calibrated operators. Accuracy of both frameworks was measured by calibrated blinded operators, who determined tactile adjustment, Sheffield test, radiographic adjustment, and screwing torque. Overall perception of adjustment was used to determine the better framework to be delivered to the patient. Hº: Frameworks obtained from an impression taken with an intraoral scanner are not inferior in accuracy to those obtained from a conventional elastomeric impression
The primary aim of the present study is to compare the accuracy of a full digital workflow for dental implants insertion to a partially digital workflow, for a limited edentulous space (1 to 3 dental units), in the maxilla or mandible.
Acqua GM (Grand Morse) Helix implants present an optimized implant design with adapted treatment protocol, allowing for treatment of patients with different bone qualities. The objective of the study is to prospectively collect clinical data to confirm the long-term safety and clinical performance of Acqua GM Helix implants and GM prosthetic abutments in daily dental practice setting, by means of success and survival rates of these devices. Devices will be used according to standard routine in daily practice, according to all indications as specified by the manufacturer in the IFU (instructions for use). patients will be followed for 36 months after implant placement.
A questionnaire based study to investigate the effectiveness of an Augmented Reality App in the selection of teeth for dentures. Patients dentists and dental technicians are asked to assess the effectiveness of the App in structured questionnaires.
Twelve participants with edentulous alveolar crests in the distal portion of the arches will be included in the study. At least two implant sites will be identified in each patient and will be sub-prepared with drills or sonic instruments. One site will be used as a test and one as a control where experimental mini-implants will be installed. Reconstructive surgical procedures will be applied at the biopsy sites.
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 aim of this project was to evaluate the impact before and after (3, 6, 9, and 12 months) of oral rehabilitation with conventionalof the insertion of new complete dentures (CD) in the oral health-related quality of life (OHRQoL) in total edentulous patients compared to dentate individuals. This is a clinical trial study approved by the Research Ethics Committee (nº 31105714.7.0000.5626 ) which was conducted on 122 patients who attended the clinics of Federal Fluminense University, with the necessity of CD. The eligibility criteria were: healthy patients without disabilities; aged up to 50 years; complete upper and or lower jaw edentulism for a minimum 5 years; the presence of adequate healthy tissue to support the prosthesis; adequate cognitive ability and understanding to respond to the questions posed. It will be excluded patient with motor disabilities, cognitive impairment and people with special needs. After the installation of the CD a follow-up of one week, three, six, nine, twelve and eighteen months will be performed. The Oral Health Impact Profile (OHIP-Edent) instrument will be applied (in form of an interview) to evaluate the impact of CD on OHRQoL. The scores of the OHIP-Edent index will be calculated using the additive method, summing the numeric response codes for each item. Shapiro-Wilk test revealed nonparametric distribution of data. Chi-square, Mann-Whitney U, and Kruskal-Wallis tests were performed for comparing groups according to sociodemographic data. Kruskal-Wallis test was per- formed for comparing groups and treatments throughout time. A significance level of 5% was adopted, and all analyses were performed on Statistical Analysis System (SAS) version 9.3 software. The responsiveness was assessed by analyzing the change of the scores on the scales and subscales. The changes was calculated by subtracting the post-treatment scores from the before-treatment scores. Positive change scores will indicate an improvement in OHRQoL, while negative scores will indicate deterioration.
