Chin area is considered as a suitable donor site for autogenous
bone grafts for alveolar ridge reconstruction before dental implantation.
Despite the common use of chin bone grafts, some neurosensory deficiency
of the of the lower lip, chin area ,
gingiva and lower anterior teeth may
occur.
Purpose: Evaluation of neurosensory deficiency of the lower lip, chin area ,
gingiva and lower anterior teeth following chin bone harvesting for
posterior mandibular alveolar ridge reconstruction.
Treatment of dentofacial deformities with jaw osteotomies has an effect on
airway anatomy, therefore mandibular setback surgery has potential to diminish airway size.
The aim of this study was evaluation the effect of mandibular setback surgery by
bilateral sagittal split
ramus osteotomy (BSSRO) on lower pharyngeal airway size in anteroposterior direction retrolingually
and hyoid bone position.
Assessment the changes in chin morphology after harvesting bone graft from
the symphysis using cephalometric radiographs.
Our present study aimed at evaluating vertical resorption
following ramus and chin grafts applied in the split space after sixmonth
implant delay.
The common problem that may encounter surgeons were the change of the volume of iliac bone grafts which used in atrophic region in the alveolar bone because of the resorption of this grafts during healing period.
This study aimed to compare between
block graft which taken by surgical bur (trephine)and grafts which collected by bone scraper ,in this way the bone graft look like small chips .This study included 10 patients who presented the oral and maxillofacial department in dentistry faculty in Damascus university between 2010-2012 A.D. the patients suffered from sever atrophy in upper and lower alveolar bone for different underlying causes and needed to compromise these atrophy to create a suitable area for dental implantation .The iliac bone grafts were turned into a real bone in the grafted area but the block grafts were saving their volumes more than the grafts collected by bone scraper. We used Mann-Whitney U and SPSS to evaluate the data that collected during the research and the results revealed that the block iliac bone graft which used to compromise the atrophic region would resorb less than the grafts which collected by bone scraper . But these grafts showed that it would be more exposed after surgery than the bone scraper grafts .
