Our present study aimed at evaluating vertical resorption
following ramus and chin grafts applied in the split space after sixmonth
implant delay.
The aime of this study was to determinethe effect of gender on the soft tissue of the
chin at each type of rotation patterns of the lower jaw (Anterior - normal - Posterior)
The sample consisted of 100 X-ray Lateral cephalometric radiographs of (69
female _ 31
male) adults, has been selected according to the following conditions: Age between 18-26
years old, , exclusion of all cases of Intenseocclusal abnormalities ,
Permanentocclusionand there is noformaldentalabnormalitieswithout takinginto accountthe
thirdmolars, The absence ofa previousorthodontic treatment, the patient free fromsystemic
diseasesorcongenital malformationsanddevelopmentaldisordersandsyndromesand there is
no story of a previous surgery in the head and neck area
The sample was divided into groups according tosex andmandibularrotation(Anterior -
normal - Posterior). Then we studied variablesrepresentative the lower jaw rotation
andanother ones representativethemeasurementsof the chinsoft tissue.
The results showed a difference theaveragesof the soft tissue thickness and the
indicators of mandible rotation between the sexes In favor of males, And theaveragesof
thevariables showed Correlationbetween chinsofttissuethicknessin femaleswiththree
typesoflower jawrotation Compared with males.
Chin area is considered as a suitable donor site for autogenous bone grafts for
alveolar ridge reconstruction before dental implantation, using large trephine bur(10mm) considers one of
several ways which appeared for bone graft harvesting. The aim
of this search is to study radiographic
density changes following chin bone harvesting for dental implantology by using large trephine bur
depending on digital panoramic radiographs.
Assessment the changes in chin morphology after harvesting bone graft from
the symphysis using cephalometric radiographs.
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.
