The intraarticular fracture of distal end of radius have bad returns more than extra articular fractures whereform the range of motion in flexion and extension, radial variance and ulnar variance of the joint. Shortness of the radius and the directio
n of articular surface of the radius should be corrected. The integrity of radial articular surface play an important rule in determining results. Displacement of the articular surface more than 1 mm cause an obstinate pain and synarthrophysis thereafter. More than 92% of the patients with disalignment of articular surfaces with space more than 2 mm end with arthrosis in the radial carpal joint. Through examening patients with union with shortness of radius more than 2 mm, we notices recuction of the wrist range of motion ) flextion-extention- pronation -supination) more than patients without shortness. Also we couldnt find sufficient statitics about the pain during motion.
Many complications are associated with the surgical removal of impacted third
molars. One of these complications is the formation of a deep periodontal pocket distal to the second
mandibular molar . Plasma Rich in Growth Factors is a material conta
ining many growth factors Which
have an essential role in wounds healing and tissue regeneration.
The aim of this study was to assess the efficacy of autologous PRGF in bone regeneration techniques to
prevent development of periodontal pocket at the distal root of the mandibular second molar following
extraction of an impacted third molar.
Distalizition of the upper first Molar is a common treatment modality and
very important method to correct Distal Malocclusion, or to create Spaces
in the upper arch.
The Distal Jet has recently been proposed to distalize maxillary molars in
Class II cases with no need for patient cooperation.
