Abstract
Purpose: this study was conducted between 2016 and 2019 at the faculty of dentistry Al-Azhar University Girls branch aimed to improve alveolar ridge dimensions for immediate Implant placement in cases with atrophic alveolar ridge.
Material and methods: six patients fulfilling the inclusion criteria were selected from the out-patient clinic of Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Al-Azhar University (Girl's Branch). Fabrication of two computer guided stents used to guide flapless ridge splitting using piezoelectric device . After ridge splitting, all patients had simultaneous implant and PRF placement followed by clinically and radiographically over a period of 6 months.
Results: was found to have successfully osseointegrated both clinically and radio-graphically. The Implant deviation from the pre-planned virtual implant position was as well found to be within an acceptable range.
Conclusion : computer guided Flapless ridge splitting with PRF and immediate implant placement is an innovative , less invasive , a traumatic , predictable technique .
