Description
DESCRIPTIVE REPORT OF INVENTION PATENT: IMPLANT-SUPPORTED PALATAL EXPANSORS
The present patent of invention talks about implant-supported palatal expansors and new modifications incorporated to the implant-supported palatal expansors presented in the first patent of invention requirement, dated from November 25th, 2005.
This new set composes the implant-supported palatal expansors braces models that are incorporated to the implant-supported palatal expansion technique, described for the first time in the referred patent. This innovative technique allows the palatal expansion without force on the teeth, avoiding damages on the teeth surfaces, that serves as support to the fixed palatal expansors, traditionally used by the orthodontists avoiding undesired movements on them. This innovative technique allows the bone palatal expansion completely, with expansion force applied near to the right and left surface of the median palatal suture through the expansor elements, developed called implant-supported palatal expansors, which can be inserted in the palatine process of the maxillary bone via trans-mucosal without necessity of surgical incision, or if necessary, a small incision.
The implant-supported palatal expansors receive new modifications in their shape to facilitate the expansor element ( 1 ) opening and its manipulation during the surgical procedure, being smaller size than the two firsts implant-supported palatal expansors braces models presented in the above mentioned patent.
However the width, Ienght and thickness of their integrant parts will be determinated yet.
Nevertheless, they still present the same goal that is to provoke the expansion of the palatine process of the maxilla, opening the median palatine suture without dental support, but directly near the right and left surfaces of the median palatine suture.
These new modifications were necessary to a better performance and reversibility in situation that need the removal and be installed in another position in the palatine process, they can be used in atresic maxilla of all types of dental malloclusions, provoking expansion or disjunction without teeth support, open of median palatine suture, secondary nasal expansion (helpful to patients with nasal estenosis) with evident improvement in nasal breathing (helpful in mouth breathing peoples), skeletal cross bite correction, allow the orthodontic treatment at same time that implant-supported palatal expansor is applied, can stay for indefinite time like contention brace of the expansion or disjunction obtained, takes up a small oral volume with easy hygiene, allow the installation in young and adults patients, there is the possibility to avoid the necessity of the disjunction palatine surgical and avoid the use of bone distractors, having many advantages in relation to the actual methods of expansion or palatine disjunction, as fixed as removal, that are still supported on teeth and mucous palatine, respectively.

The 4th implant-supported palatal expansor model, supported by 2 implant elements type screw ( 34 ) is characterized by an expansor element ( 1 ) that transpass thread in the anterior part ( 23 ) of 2 fixation bases ( 24 ) that have a support cavity ( 35 ) in its posterior part ( 36 ) where the implant elements type screw ( 34 ) are connected ( 34 ) these elements have a screw part ( 37 ), a trans- mucous part ( 38 ), a support head ( 39 ) with screwing edge ( 40 ) that serves to fix the fixation bases ( 24 ) keeping them far from the palatine mucous and an internal fitting ( 41 ) in the superior part. The 4th model was designed to be screwed directly on the fixation bases ( 24 ). The lengths, widths and thickness of the integrant parts of 4th model, will be determined yet.
The 5th implant-supported palatal expansor model, supported on 2 implant elements ( 28 ) and having a stabilizing bar ( 42 ) is characterized by two fixation bases ( 36 ) with double extremity that are transpassed by an expansor element ( 1 ) in its anterior part ( 23 ) and a stabilizing bar ( 42 ) in its posterior part ( 35 ) and in the central part of the two fixation bases ( 36 ) there is a support cavity ( 25 ), where the head ( 27 ) of the implant elements ( 28 ) is connected, these elements have a screw part ( 29 ) a trans-mucous part ( 30 ), a tipping platform ( 31 ) and a head ( 27 ) that serves as support to the fixation bases ( 36 ) on the superior part of each head ( 27 ) where there is an opening ( 32 ) to the connection of cover's screw ( 33 ) that fixes the fixation bases ( 36 ) to the implant elements ( 28 ). The lengths, widths and thickness of the parts of 5th model will be
determined yet.
The insertion technique appropriated to the first and second implant- supported palatal expansors braces models, supported by 4 and 2 implant elements ( 6 ), respectively, will be shown. However, in this disposition the implant elements ( 6 ) can be threads in bone through a insertion procedure via trans- mucous, without necessity of surgical incision, with ease installation and removal, having the quality of reversibility, a utility quality for the cases with the necessity of its removal and installation in another place in the palatine process of the maxillary bone. The method is the same as the traditional ones of the implantology, initial perforation with an spherical drill to mark the places of insertion of the implant elements, after is followed by the use of a cylindrical perforation drill of lesser thickness than the thickness of the implant elements, these elements must be inserted manually or using a micro-motor with reduction, regular and constant pressure, until the implantation elements totally located into the bone. In some cases, if necessary, can be made small surgical incision to move the mucous and installation of the implant elements (6), directly in the exposed surface of the palatine process according to the technique described above.
After the insertion of the implant elements ( 6 ), in general the sutures can be done, if necessary, and the implant-supported palatal expansor, previously chosen by the professional, can be adapted to the heads of the implant elements ( 6 ) and fixed by the cover's screws ( 11 ).
The insertion technique of the 3rd, 4th and 5th implant-supported palatal expansors models will be described more ahead. However, in the present disposal, the implant elements of these models can be inserted through an procedure via trans-mucosal, without necessity of surgical incision, with ease installation and removal, having the quality of reversibility, useful quality for cases when there is the necessity of its removal and installation in another place in the palatine process. The insertion technique of these 3rd, 4th and 5th models is through self- screwed, via trans-mucous, where the proper implant element is used to open its bone store, therefore they must be inserted using a micro motor with reduction and after receive torque until the screw part ( 29 ) & ( 37 ) of the implant elements are totally located in the palatine process of the maxilla, remaining only a small trans mucosal part ( 30 ) & ( 38 ) out of the palatine mucous.
With relation to the activation of the 5 models of the implant-supported palatal expansors, can be fixed directly in the bone, must wait scientific studies to determine how many turns could be done to the expansor element ( 1 ) per day, however the activation must respect the patient sensitivity, being able to be done from 1 to 4 turns per day, or in alternated days to avoid exaggerated rapidly opening in the expansor element ( 1 ) and increasing the local pain.
In adults patients, who the palatine suture is certainly fused, can be ecessary an expansion surgically watched. In these cases the implant-supported palatal expansor chosen to be used, can be installed in the same moment of the
surgery not being necessary previous installation of expansor.
So, the implant-supported palatal expansors work as the others expander braces supported by teeth, but its strength is totally implicated in the palatine suture of the maxillary bone provoking a totally palatine disjunction, without strength on the teeth, neither provoking damage to the dental roots nor undesired movements and without undesired volume in the patient's mouth, can also stay more time installed working as contention brace of the expansion obtained and do not impede the orthodontic treatment progress.
