Guided Sausage Technique in Bone Regeneration As a Novel Digital Work Flow

The goal of this clinical trial is to compare amount of bone resorption and flap dehiscence following guided bone regeneration with or without digitally designed surgical guide. The main questions it aims to answer are: * Does it differ in amount of bone resorption between the conventional and digital guided bone regeneration? * What is the difference between conventional and digital protocols regarding flap dehiscence following guided bone regeneration? Researchers will compare digital guided versus conventional technique to choose adequately which protocol to use. Participants will: * Receive guided bone regeneration around implant * Visit the clinic after 2,7,14 days for detection any signs of flap dehiscence * Bone gain and bone density will be assessed after 6 months
