Description

[0001] Orthodontic treatments are performed by using

removable and fixed appliances. Fixed appliances meth-

ods are developing continually.

[0002] The prevention of the occlusal contacts may be

occasionally necessary during fixed orthodontic treat-

ments. 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 applica-

tion 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, alter-

natively. 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 sub-

jectisquiet ignored.Fine, indeep-bite cases, has bonded

"Begg" brackets to the maxillary central incisors to pre-

vent the shearing of the lower incisor brackets. Further-

more, 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 ex-

isting treatment accessories.

[0010] J. Donald Kinkade has developed an anatomi-

cal 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 facil-

itate breathing for scuba divers and patients who are at-

tached 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 devel-

oped 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 Con-

gress 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 pub-

lication, with my clinical experiences, I developed the

original model and reached to it’s final form, which be-

came 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 tem-

porarily 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 tem-

porary 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 biteraiser can be

preferred and recommended on proper cases and can

be used with any fixed appliances with minimal modifi-

cation.

Figure 1: View of the biteraiser.

The components of the biteraiser 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 biteraiser 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 biteraiser

into the molar tube, and a pair of "proximal wings", ex-

tended 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 (Fig-

ure 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 biteraiser. 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 wid-

Page 3

EP 1 217 965 B1

ening the metal surface on the palatal angles. On the

palatal side, there is a "T’’ shaped palatal spur (or T-

hook), 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 insuf-

ficiency of raising the bite.
