NCT07369583
20 edentulous patients presented for full-arch rehabilitation and was managed using a motion-integrated, fully digital workflow that combined the M-4 protocol in the maxilla with the All-on-4 concept in the mandible. Dual-scan CBCT and facial scans enabled prosthetically driven planning, while stackable and mucosa-supported surgical guides facilitated precise implant placement. Real-time jaw-motion data were incorporated into the design process to individualize occlusion, and definitive monolithic zirconia prostheses were fabricated and delivered on titanium multi-unit abutments using Rosen screws.
NCT07177521
The placement of short implants in post-extraction sockets is a valuable option when residual bone height is limited, minimizing morbidity and treatment time. The management of the peri-implant gap and soft tissues may influence primary stability, hard/soft tissue remodeling, and implant success.

NCT06155630
CAD/CAM (computer-aided design and computer-aided manufacturing) can be a game-changer for better access to care by edentulous patients. Digital overdentures offer potential for more satisfied patients due to better fit and can be provided faster/with lower costs. Providing digital overdentures has potential to enhance access to oral healthcare by the elderly, given the expected benefits (better quality, simpler, faster and more affordable than those obtained traditionally). However, evidence from randomized trials is crucial to verify the relevance of those benefits, especially from the patient perspective, and to confirm those benefits. This trial also serves as an opportunity to improve CAD software and materials, since it will identify technical challenges specific to the provision of digital overdentures. This randomized cross-over trial aims to reveal whether implant-retained mandibular overdentures (IMO) produced by CAD and 3D printing are more satisfactory to edentulous seniors than those fabricated using traditional methods. The investigators will recruit 26 edentulous participants (any sex/gender) amongst previous patients at McGill University, based on the following eligibility criteria: complete edentulism, elderly (age ≥60 years, according to the WHO), need for new maxillary and mandibular complete dentures, ability to complete questionnaires, and previous treatment with two implants in the anterior mandible. Each participant will receive two pairs of dentures, as per the McGill Consensus on Implant Overdentures (i.e., a mandibular overdenture opposed by a maxillary complete denture: (i) one by digital rendering of the mouth, virtual prosthetic design and 3D printing; (ii) a control pair, by traditional clinical and laboratory methods. Each pair will be worn for 3 months according to a random sequence (total follow-up: 6 months after the delivery of the first pair of dentures). Both overdentures will be retained by 2 Novaloc abutments and medium retention matrices. Outcomes will include patient satisfaction ratings and oral health-related quality of life. The investigators will evaluate other patient-reported outcomes, as well as clinician-assessed quality and cost. Outcome assessment will occur at baseline, then at three months after participants have worn each pair of dentures. Following the cross-over, participants will keep their preferred denture pair and return after 12 months to evaluate maintenance requirements, including stained and broken dentures.
NCT05777980
This study examines the effects of prosthetic treatment options applied to edentulous geriatric individuals who applied to Marmara University Faculty of Dentistry on chewing function, food consumption status, malnutrition status and oral health-related quality of life.
NCT04985747
The palatal rugae, refer to asymmetrical and irregular elevations of the mucosa located in the anterior third of the palate, on each side of the median palatal raphe and behind the incisive papilla. The lack of the rugae area on the polished areas of the dentures has been suggested to impact phonetics in denture patients due to lack of tactile feedback. Therefore, the aim of this randomized crossover clinical trial was to compare patients' reported satisfaction with their complete dentures and oral health related quality of life, when provided with a denture with a rough palatal surface in the rugae area compared with a polished palatal surface or an open palatal surface.
NCT03687047
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.
NCT04755166
Background: Placement of oral implants is frequently compromised due to atrophy of the alveolar process. Lateral ridge augmentation with an autogenous bone block is frequently necessary to increase the width of the alveolar process before implant installation. However, harvesting of an autogenous bone block is associated with donor site morbidity. Consequently, bone substitutes alone or in combination with particulate autogenous bone graft are used increasingly to simplify the surgical procedure. Animal and human studies evaluating lateral ridge augmentation with Bio-Oss alone or in combination with particulate autogenous bone graft have demonstrated new bone formation and high implant survival. However, the optimal ratio of Bio-Oss and particulate autogenous bone graft for lateral ridge augmentation and long-term implant survival is unknown. Purpose: Test the H0-hypothesis of no difference in long-term implant survival, newly formed bone, volumetric stability of the graft, gained width of the alveolar process and patient satisfaction after lateral ridge augmentation with Bio-Oss alone or in combination with a diminutive amount of autogenous bone graft. Material and methods: lateral ridge augmentation will be performed in 20 adults with two different ratios of Bio-Oss and autogenous bone graft after a split mouth design. Clinical and radiological measurements will evaluate the long-term implant survival. Cone beam computer tomography (CBCT) will be obtained preoperatively, immediately postoperatively, prior to implant placement, 2 years after implant installation and 5 years after implant installation to estimate the volumetric changes of the augmented area. Moreover, the amount of newly formed bone will be estimated by histologic evaluation after implant placement. Conclusion: Long-term implant survival has never been evaluated after lateral ridge augmentation with Bio-Oss alone or in combination with a diminutive amount of autogenous bone graft.

Implant retained overdentures are a cost-effective treatment for elderly patients suffering from complete tooth loss. Despite the high success rate of implants in the general population, older adults lacking all teeth are a challenging population for implant therapy, often presenting limited bone disponibility, narrow alveolar ridges, diminished bone density, scarce inserted gingiva and several co-morbidities.Thus, improving their possibility of success in implant therapy avoiding further surgical interventions is key. Platelet-rich fibrin (PRF) is a blood derivate that can be easily and economically obtained from patients and that has shown promise of reducing the complications and improving the success of implant therapy, nevertheless its benefits in patients receiving implant retained overdentures has not been stablished. It is possible that PRF can improve the results and diminish the complications of implant therapy in older adults. The investigation aims to demonstrate that the use of platelet-rich fibirn (PRF) is safe and beneficial for implant treatment in older adults suffering from complete tooth loss.
