简要总结
The goal of this clinical trial is to compare in patients with atrophied anterior maxilla, bone augmentation techniques ( gold standard bone block and tent pole technique).
The main question it aims to answer is :
Does screw tent pole technique provides better bone gain than autogenous bone block in atrophied anterior maxilla?
- primary objective to assess amount of bone gain
- secondary objective assess bone quality Participants will be randomly divided into two groups study group ( tent pole technique) and control group ( bone block) - each group will be followed up monthly for soft tissue dehiscence and after 6 month to assess bone gain and bone quality and then implant placement.
详细描述
• Research question: Does screw tent pole technique provides better bone gain than autogenous bone block in atrophied anterior maxilla?
• Rationale for conducting the research: Several methods have been developed for the augmentation of the deficient bone volume. These include Guided Bone Regeneration (GBR) with barrier membranes, onlay bone grafting, ridge splitting and distraction osteogenesis.
The screw tent-pole method is an effective technique to achieve initial reconstruction of alveolar bone deficiencies. Previous studies have proven that screw tent pole technique is recommended in reconstruction of atrophied alveolar bone and its good outcome in contrary to other bone graft techniques.
This study aim to compare the outcome of screw tent pole technique to conventional gold standard technique of block bone grafts in atrophied anterior maxilla.
