Abstract
ABSTRACT
A bristle shaft bundle for use in total disinfection of subgingival periodontal pockets, periodontal pocket edges and tooth surfaces has individual bristle shafts arranged coaxially in a ring. A rotationally symmetrical gingival edge cup is provided, in which the bristle shaft bundle is arranged so as to project outwardly in a cylindrical way, continuing in a shaped manner to a cross-section increasing in the shape of a circular cylinder. The two innermost, reinforced bristle layers exhibit in individual cases rotationally circular bristles and project above the multiply stepped, remaining layers, which drop away towards the outside. The inner layer projects further than the adjacent layer to form an exposed layer. A connection layer is provided with a pointed device and the inner layer is provided on the front face of the projecting section with a shaped cross-section which as chosen can be either corrugated, serrated, roof-shaped or pointed and forms an individual, coaxial bristle shaft ring.

~ristle shaft bundle and bristle shaft devices for total subgingival rinslng of ~~~~~
periodontal pocksts, periodontal pocket rims and tooth surfaces.
The invention is based on a new concept: "Health instruction in the field of periodontal pockets" for permanent teeth in the open space of the human mouth and solves this problem by means of a revolutionary new therapy, the use of which puts a stop to the advance of the bacterial process of destruction on all 32 perlodontal pockets which exist around the tooth necks.
To achleve this the latest state of the art has shown that instead of caring for the teeth by cleaning, residual food containin~ carbohydrates should be removed daily from the sub~lngival gap of the perlodontal pocket between the tooth enamel and the epithellal tissue, this bein~ carrled out from the ligamentum circulare towards the tooth crown surface in order to protect the connective tissue fibre of the dental periosteum, from whlch emer~e numerous Sharpey fibres into the dental root cement, from substances which cause rot and decay.
Teeth require such biolo~ica] di.sinfHct~on bec~usc thc force arisin~ due to thc pro.-es6 of chewirl~ pre~sf.~.~s the m~stlc~ted focd up intD the 5nost remote oorFler~ to the ligAmentum circulare, this processs of accumulatlon and deposit causillg fermentatlorl substances and aclds to arise which in the lons run act on the hard thin substances of the tooth enamel which coats the tooth completely and which is composed of appro~. 88% calcium phosphate, 2% or~anic substances, 1.5%
ma~rlesium phosphate, .3~/0 calclum fluoride and .2% fat.
~27S~64 In addition due to infection they also lead to lnflammation of the connective tissue flbres of the dental periosteum and the Sharpey fibre, thus thwartin~ the purpose of the firm and inherent connectlon of the two tissues to the root cement and the bone wall of the ~.lveola as well as the ~lveolar septa in the inter-radicular space.
The process of cleaning the teeth daily on the tooth crown only leads to a lack of mouth secretlon and acid on the tooth enamel; the chemical influences and acids between the epithelium and tooth enamel which are not naturally interconnected have thus remained unaffected to the present day.
The techniques employed for tooth care ~n the USA and the Federal Republic of Ger~any as well as other countries all over the world usin~ tooth brushes or rotation cups fitted with brush arran~ements, published under USA Patents 3,335,444 and 3,177,510 and Patent DE-PS 24 61 053 C2 are ineffective because by this means it is only possible to clean the tooth crown surfaces, to disinfect the periodontal pocket rim and to massage the external ~ums with their mucous membrane.
This is the state of the art as ls considered already familiar in the present applicatlon documents.
Daily disinfection of the periodontal pockets represents a contrasting approach which will offer resistance to the universal sickness of bad teeth and which wlll be of ~reat benefit for humanlty.
~ooth decay and periodontopathlc d1sorders ~rise due to unemptled and non-di~infected sub~lrlglval periodontal pockets in whlch accumulations and depo~its of masticated food containing carbohydrates on the ligamentum clrculare cannot be removed by traditional methods and means of dally tooth care. For the fi.rt tlme the nature of the incidence of tooth decay and periodontopathlc dlsorders and ln partlcular ~27S'764 their reason for arisal has thus been proved and explained scientifically.
Due to scientific advances in the application of such a hi-tech products as bristle shaft devices intensive care is provided between the tooth enamel and the epithelial tissue up to the ligamentum circulare because in accordance with the invention the appropriately shaped bristle shaft tips not only remove the mucous secretion but also help to bring about definitive healing of alveolar pyorrhoea without any irritation by additional antiseptics.
For rotating penetration to the ligamentum circulare a natural, individual, reinforced, rotationally circular bristle shaft is required which consists of piled-up keratinised cells, a medullary strand, a cortical layer, and an outer skin of average hardness; this is arrived at by a specific shaft section and a bristle shaft bundle drawn coaxially into a gingival rim cup in accordance with the invention and in agreement with the main content of Claim 1.
The procedure of raising accumulated and deposited substance which cause decay from the subgingival periodontal pockets on to the tooth crown surfaces as well as the process of rinsing the tooth surfaces is carried out in one operation by gentle control of the periodontal pocket device by the user himself by applying the bristle shaft device of the present invention on the periodontal pocket rim (margi.nal gingivcl). As ~ re~ult of this the tooth ~urfac~ ln tho oonlc trape~e ~pace are included and in the cour~e oE the two-fold rotatlon process the following effects are brought about in one smooth operation taking about 40 seconds:
LCM: ~c 3 ~27~;764 - Protection from decalcification of tooth enamel, - Protection from decay incidence, - ~rotection from inflammation of ligamentum circulare, - Protection from al~eolar phorrhoea (paradontitis, periodontal disorders), - Protection from soft tooth plaque deposits and bad breath, - Visibility of dentin tooth colour due to transparency of the tooth enamel.
Generally speaking, the present invention may be considered as providing a bristle shaft device for use in disinfecting subgingival periodontal pockets, periodontal pocket edges and tooth surfaces, the device comprising: a rotationally symmetrical gingival edge cup having an axis and an external periphery; and means for disinfecting subgingival periodontal pockets, periodontal pocket edges and dental surface and including a plurality of coaxial bristle shafts arranged coaxially in a ring and held in position by the cup, the shafts projecting from the external periphery, the plurality of bristle shafts being formed as individual radially adjacent bristle layers, one of the layers extending beyond other layers so as to have an exposed end for penetrating into a subgingival periodontal pocket up to a ligamentum circulare, another of the layers being arranged adjacent to the one layer for resisting a bending of the exposed end, the remaining layers of the bristle layers being formed as multiple stepped layers which drop off in steps from each other in a radially outward direction for further reinforcing the one layer and the another layer, the one layer be~ny radially innormos~ of the rest of the layers, the one layer and the another layer projectiny beyond the remaining layers, the exposed end of the one layer being formed with a projection 80 as to form an individual, coaxial bristle shaft ring.
