Filter by:Background: Lateral maxillary sinus augmentation (MSA) is a predictable bone regeneration technique in case of atrophy of the posterior-upper maxilla. Aimed at obtaining quantity and quality of bone suitable for receiving osseointegrated implants, its success is largely due to the skill of the surgeon, but also to the characteristics of the biomaterial used. Methods: Twenty-four patients needing MSA were included in the study. The patients were randomly allocated to 3 different groups: Anorganic Bovine Bone Mineral (ABBM) as control, Tricalcium Phosphate (TCP) with or without hyaluronic acid (HA) as test groups. Nine months after MSA bone biopsies were harvested for the histomorphometric analysis. Secondary outcomes were mean bone gain, intraoperative and post-operative complications, implant insertion torque, implant failure and patient related outcome measures (PROMs).
This study evaluates the effect of citric acid demineralization in autogenous bone blocks consolidation. Half of participants will receive citric acid treatment at the bone block and recipient site. Other half will receive no demineralization treatment.
In this study, the investigators will evaluate the dimensional changes of alveolar bone in the preserved sites in comparison with extraction only conventional healed sockets, as well. 1. Dimensional changes of the alveolar ridge contour after socket preservation in comparison to conventional tooth extraction. 2. Evaluation the stability of implants placed at the preserved sockets. 3. Histological evaluation of newly formed bone at the socket preserved sites in comparison with extracted only healed sites.
The hypothesis of this study is that there is a significant difference in bone maturation after sinus grafting determined by the distance from the buccal to the palatal wall of this cavity.
