Официальное название
Maxillary Sinus Augmentation Through Lateral Window Technique: Outcomes of Different Bone Graft Combinations (MSA-BGC STUDY)
Обзор
This study investigates the outcomes of a surgical procedure that is performed to increase bone support at a future implant site on the upper back jaw area. This procedure requires placing bone graft material and/or substitutes into the maxillary sinus. The average healing time for the graft is about 6 months. Then, the site will be ready for dental implant. The study will compare healing outcomes of two types of bone graft mixtures used on the same patient (right and left upper jaw regions). The outcomes will be evaluated through clinical examination but also by studying the quality of the tissue through tissue biopsies obtained from grafted sites.
Вмешательства
- Устройство Bone grafting on both sides
The surgical protocol is part of standard of care and will not be changed due to the study except the choice of the bone graft. Routinely (as the standard protocol), allograft (Straumann Allograft mineralized cortical granules \[0.25-1mm\]) is mixed with xenograft (bovine bone; Bio-Oss® small particles \[0.25-1mm\]) bone graft and placed into sinus. In this study, one randomly chosen sinus will receive this mixture (50:50 by volume) as the control. The other sinus on the same patient will receiv
