Aim: The aim of the present study to determine the Ridge Split with Piezotome in Deficient Edentulous Region of Maxilla and Mandible and Immediate Placement of Implant in Bihar region. Methods: A retrospective study was conducted in the Department of Dentistry, Jawaharlal Nehru Medical College and Hospital, Bhagalpur, Bihar, India, for 15 months. 30 patients of age 18-62 years, with partial or completelyedentulous alveolar ridges of insufficient alveolar ridge width (thin/ knife-edge ridges) of no less than 3 mm and indicated for a ridge augmentation by ridge split techniquewere included in the study. A standard aseptic surgical protocol was adopted in all thecases to place the implants. The IOPA’s of all the patients were collected, at the time of implant placement and after 6 months post op. The length of the implant and the level of crestalbone on both mesial and distal sides are measured in millimeters (mm) with the help of a metallic scale. Results: Out of 30 patients that were included 66.67% were female, inwhom 9 implants were placed in anterior maxilla, 11 implants in posterior mandible and 3 implant in posterior maxilla) and 33.33% were males in whom (6 implants were placed in anterior maxilla and 3 implant placed in posterior maxilla). Out of 32 implants, 6 implants were positive for percussion test and 3 implant shown lower ISQ value which resulted in the failure of the implant which was placed in the posterior maxilla. T-Test results were mean value for initial ridge width was 3.8 and the final ridge width was 7.5. The significantdifference is .001. In our study, the mean CRBL immediately at the time of implant placement in 0 months was .08 on the mesialaspect and 0.14 on the distal aspect. Mean CRBL value after 6 months was 0.57 on the mesial aspect and 0.45 on the distal aspect. There has been found a significant bone loss after 6 months of implant placement. P-value was 0.012 (p<0.005). Conclusion: The modified ridge split technique in posterior mandible, anterior maxilla and posterior maxilla is a simple and predictable procedure with satisfactory results. Moreover, this approach is devoid of foreign materials usage and has a low rate cost, therefore, could be employed more often.
