Abstract

Soon after its introduction by W.Clark in 1977 as
device is frequently used in the treatment of class II
orthodontic anomalies. In contemporary literature very
little has been reported with regard to the advantages
and limitations of this widely used functional appliance
nt therefore, the main goal of this research was set - to
make a literature review to describe the indications,
advantages and limitations of these orthodontic
appliances.
Adequate literature research was performed to fulfill
the main goal. As sources of information was used Pub
Med. The keywords used for searching were “twin
block, indications”, “twin block, advantages”, “twin
block, limitations”, “twin block, disadvantages”.
Twin Block device is indicated in cases such as: class
II 1st dev, class II 2nd dev and class III malocclusion,
frontal open bite, deep bite,cross bite, asymmetries
faces, TMJ disorders. It is favorable because it is very
well tolerated by patients, easy to repair, suitable to use
in permanent and mixed dentition and compatible with
f
ixed orthodontic appliances. The biggest advantage is
that there is no difference in either dental or skeletal
changes achieved with partial or fill time wear over
12 months. Most important disadvantages when using
this orthodontic appliance are protrusion of the lower
incisors and lateral open bite.
The possibilities to influence on the type of growth are
limited because they depend on a number of factors,
however, usage of the Twin Block device can achieve
satisfactory effects on the growth of the bone segment
of the orofacial system.
Keywords: twin-block, advantages, limitations,
indications, effects
