Impaction of the lower second molars is quite rare ranging from 0 to 2.3% population and represents 0.03 0.04% overall dental impactions. This article aims present illustrate simple orthodontic management approaches impaction in synergy with Regional Acceleratory Phenomenon along an overview main therapeutic options, their indications, drawbacks.

PURPOSE Osteochondral impaction grafting to manage isolated chondral defects in femoral condyles usually uses a metal punch to impact the grafts into predrilled cavities. Damage to the chondrocytes during impaction is a concern, however, and new methods are being sought to minimise the damage. We studied if impaction with a plastic punch instead of a metal punch reduces the extent of chondrocyt...

OBJECTIVE To investigate the prevalence of impaction of permanent mandibular second molars and associated dental and radiographic characteristics of Chinese children in Hong Kong. MATERIALS AND METHODS Dental and radiographic records of a group of Chinese schoolchildren were studied retrospectively. Cases of impaction of 1 or both permanent mandibular second molars were selected. Demographic ...

As impacted permanent maxillary cuspids occur in 1-2% of the population, the general dentist should know the signs and symptoms of this condition and the interceptive treatment. Features of buccal or palatal cuspid impaction include lack of canine bulges in the buccal sulcus indicating a lingual eruption path and possible impaction; lack of symmetry between the exfoliation and eruption of cuspi...

Our aim was to determine the effect of the initial pattern of fracture and the displacement of fragments on the outcome of proximal humeral fractures treated conservatively. We followed 93 consecutive patients prospectively for one year. Final movement and strength were compared with those of the contralateral side. The final American Shoulder and Elbow Society score and the Disabilities of Arm...

In revision total hip replacement, bone loss can be managed by impacting porous bone chips. In order to guarantee sufficient mechanical strength, the bone chips have to be compacted. The aim of this study was to determine in an in vitro simulation whether the use of a pneumatic hammer leads to higher primary stability than manual impaction. Bone mass characteristics were measured by force and d...

Keywords: Powder dispersion Impact angle Agglomerates Computational fluid dynamics Discrete element method a b s t r a c t This paper numerically investigated the mechanisms of powder de-agglomeration on mechanical impaction, aiming to explain the experimental observations in our previous study (Adi et al., 2010). A numerical model based on a coupled computational fluid dynamics (CFD) and discr...

Hematological and biochemical parameters were determined in 82 West African Dwarf goats with foreign body rumen impaction (FBR) and 40 normal WAD goats without foreign body rumen impaction (WFBR) in order to evaluate their influence on the etio-pathogenesis of rumen impaction. The mean PCV (26.22%), RBC (9.03 X 106/µL), Hb (8.38g/dl) and MCHC (32.20g/dl) were significantly lower in FBR than in ...

Background Impacted third molars may be responsible for various problems within the oral cavity. Impaction may be due to inadequate space or varied angulations. Assessment of variables contributing for impaction may influence the fate of impacted third molars. MethodologyRetrospective analysis of panoramic radiographs of adolescents in Indian population subpopulation was done to evaluate angula...
