Lnfluence of the Prosthetic Emergence Profile on the Prevalence of Peri-implant Diseases

Sponsor: Ramón Pons Calabuig

Summary

1. Objectives: To evaluate the influence of the shape and contour of implant-supported restorations on peri-implant soft and hard tissues by using an intraoral scanner. 2. Material and methods: 1. Number of patients to be treated: 120 2. Number of visits per patient: 1 3. Brief description of the different techniques used in the study, authorized and validated in the literature (3-5 lines). A clinical and radiographic evaluation of the dental implants of those patients who are undergoing maintenance therapy treated by the Department of Periodontics of the International University of Catalonia prior to 2017 will be carried out. Additionally, a digital scan of the crown will be carried out using a intraoral scanner. Finally, patients will fill out a questionnaire about their routine dental care. 4. Benefits and harms of participating in the study for the patient Participating in this study implies irradiating the patient through a periapical x-ray in order to assess the bone level of their implants and therefore be able to diagnose the presence or absence of peri-implant disease. Regarding the possible benefits, the patient will help the scientific community to determine the ideal contour and shape of the implant-supported restoration that will prevent the appearance of peri-implant diseases. Likewise, patients will undergo an exhaustive clinical and radiographic review that will allow their dental and periodontal status to be updated. 5. Alternative treatment in case the patient does not wish to participate in the clinical study As this is an observational study, there is no alternative treatment. The patient will have absolute freedom to decline to participate in the study. 6. Treatment to be carried out in the event that complications arise in the patient, once the clinical study has begun If after handling the prosthesis, it is detected that any of the screws that support the prostheses are loose or defective, the MORE department will be informed in order to replace said accessory. On the other hand, they would be informed in the same way in case of detecting any complication/alteration with the patient's implant-supported crowns. 7. Material needed to carry out the study ( To carry out this study, you will need posterior radiographic positioners, radiographs, an intraoral scanner (3Shape Trios®), the implant analogs or replicas, and a basic periodontal examination set (exploratory probe, periodontal probe, Nabers probe, mirror). and tweezers). 3. Evaluation of experimental and statistical results (3 lines) - The data obtained will be analyzed through a descriptive statistical analysis (mean, median and standard deviations). The qualitative variables will be expressed in frequencies and percentages. In addition, logistic regression analyzes will be performed to determine the association between peri-implant status (at the implant and patient level) and the angle/emergence of implant-supported prostheses.
