Popis: Aim: The aim of this study was to detect the effect of flap technique on crestal bone resorption during healing and loading period in implant supported overdentures. Material and Methods: A total of 8 patients, 5 male and 3 female, ranging from 50 to 70 years of age, having completely edentulous maxillary and mandibular arches were selected for the study the whole study was conducted in 4 phases. In the 1st phase Clinical Diagnosis, Treatment Planning & Denture Fabrication was done. The selected subjects will be diagnosed and treatment planning for new denture fabrication was done. In the 2nd phase the denture insertion was done and if required occlusal correction was be performed. After initial recall visit, patient was recalled again after one week of denture usage. In this visit 1st stage of implant surgery was conducted. Dental implant in the mid symphyseal region was placed following all the surgical protocols. Immediately after surgery first IOPA with RVG was taken. After the surgery the denture was relieved at the surgical site and patient was asked to use the same denture. Subsequently after 4 weeks and after 12 weeks of healing the second and third IOPA with RVG was taken. The computer software was used for measuring the bone level. After 3 months of Osseointegration period in phase 3, the loading of the implant was done by incorporating O ring attachment. Again after 4 weeks and after 12 weeks of loading the fourth and fifth IOPA with RVG was taken. The magnification error was checked. The data obtained was saved using Paint software used in Microsoft 8.1. The data so obtained for measuring the bone levels with the help of computer software (RVG 5100) was tabled and statistical analysis was done. Results: The mean rate of crestal bone loss with time was more during first month (0.35mm) then it decreased in 3rd month (0.51mm) and further decreased during 4th month (0.59mm) and 6th month (0.70mm) follow up period. Conclusion: The concept of single implant supported overdentures provides another option for completely edentulous elderly patients with severely resorbed mandibular ridge & with economic constraints in developing countries. Keywords: Dental implants, Overdenture, Residual Alveolar Ridge, Crestal Bone loss, Intraoral Digital Radiography (RVG 5100).
