Description
[0001] Orthodontic treatments are performed by using
removable and fixed appliances. Fixed appliances methods are developing continually.
[0002] The prevention of the occlusal contacts may be
occasionally necessary during fixed orthodontic treatments. Treatment of some cases such as deep-bite,
cross-bite and scissors-bite with fixed appliances, it is
usually necessary to open the bite temporarily in order
to prevent bracket shearing and to allow for easy tooth
movement.
[0003] In the treatment of deep bite cases, bonding of
the lower incisors requires a certain time. Since, on such
casesthe bitemust be openedsufficientlybefore bonding
of the lower incisors. Otherwise, the upper incisors may
cause the shearing of those brackets.
[0004] In the treatments of the "buccal non-occlusion"
and "telescopic bites", the bite must also be raised to
allow for easy tooth movement.
[0005] Likewise, in the treatment of the "anterior and
posterior cross-bites", temporarily opening the bite will
ensure easy tooth movement and easy expansion in a
short time.
[0006] Out of the above mentioned reasons, raising
the bite, may be necessary in many cases.
[0007] Temporaryand instant raising of the bite, during
fixed orthodontic treatments are commonly obtained by
using removable occlusal plates. However, the application of these plates, beside of their difficulty of usage,
requires complete patient co-operation.
[0008] Bonding ofrestorative materials on the occlusal
surfaces of the posterior teeth can be performed, alternatively. Application of these materials is an appropriate
method for bite opening however the adhesive force of
these materials is nor sufficient to resist to the occlusal
forces due to the absence of cavity preparation. Also,
this method could not ensure the hygienic since, the rest
of these materials could not be cleaned sufficiently after
their usage.
[0009] Review of the literature revealed that this subjectisquiet ignored.Fine, indeep-bite cases, has bonded
"Begg" brackets to the maxillary central incisors to prevent the shearing of the lower incisor brackets. Furthermore, the shearing of the lower brackets were tried to be
prevented by using lingual brackets which are as fragile
as the lowers. More over, this is not an invention, nor a
different wire bending. This is a different use of the existing treatment accessories.
[0010] J. Donald Kinkade has developed an anatomical mouthpiece which relates to mouthpieces which are
used in underwater breathing devices such as snorkels
and regulators and also to mouthpieces which are used
in inhalators and gastric tubes for medical treatments
(Document US-A-5203324). This device is used to facilitate breathing for scuba divers and patients who are attached to life supporting medical machines. Although this
device has an occlusal part, it has not any relation with
"bite raising in orthodontics" nor "bite opening".
[0011] To solve the limitation of instant and temporary
bite raising during fixed orthodontic treatments, I developed a special wire bending and I published it’s usage
as a case report in the Journal of Turkish Orthodontic
Society, in 1995. Same year, 1 presented it in the name
of "Semi-fixed Temporary Bite-raiser" in the 71th Congress of European Orthodontic Society, in Bergen-Nor-
way. This article is also published in the April 1999 issue
of the Journal of Clinical Orthodontics. Since it’s first publication, with my clinical experiences, I developed the
original model and reached to it’s final form, which became now available to the serial fabrication. In other
words, it resembles to it’s original by it’s function, but it’s
form and usage facilities are totally developed. Due to
these properties, it became also a commercial article.
[0012] The aim ofthisinvention,is to instantly and temporarily raise the bite, as described above. However, the
most important is thatthebite-raiserdoesnotnecessitate
patient co-operation since, it is tightened to the molar
tube by its proximal wings and this peculiarity ensures
success of the treatment, in a short time. Furthermore,
it is also valuable for its optimal hygienic conditions. It
has no pathological effects on the molars due to its temporary usage. Molar intrusion may be observed in a long
time application and this reversible tooth movement can
be compensated with arch bending.
[0013] This instant and temporary bite raiser can be
preferred and recommended on proper cases and can
be used with any fixed appliances with minimal modification.
Figure 1: View of the bite raiser.
The components of the bite raiser are numerated in the
figure and described below;
1. Insertion wings,
2. Proximal wings,
3. Occlusal stops,
4. Palatal spur and raise increasing piece (T-hook).
[0014] The bite raiser constructed by using 0.8-1.0
mm. Cr-Ni, titanium, stainless steel or similar metals.
Vestibular side is consisted of two types of elements; a
pair of "insertion wings", serving to insert the bite raiser
into the molar tube, and a pair of "proximal wings", extended from the insertion wings, serving to attach the bite
raiser to the molar tube by an elastic ring or a ligature
wire (Figure 1, no.1 & 2). The two arms of the ensemble
extend to the occlusal surface of the tooth with an angle
according to the anatomical form of the molar tooth (Figure 1). On the occlusal surface, three "occlusal stops"
are extended from the three sides of the occlusal part
(Figure 1, no. 3). They could be bent to the occlusal pits
of the molar tooth to increase the stability and the height
of the bite raiser. The shape is wider on the palatal side,
and narrower on the vestibular side. This shape provides
the settling of the reinforced palatal angles, on the palatal
cusps of the molar tooth. Reinforcement is made by wid1

ening the metal surface on the palatal angles. On the
palatal side, there is a "T’’ shaped palatal spur (or Thook), serving to attach the raiser to the palatal part of
the molar band (Figure 1, no.4). This T-hook could also
be bent to the opposite side, in the condition of the insufficiency of raising the bite.
