Abstract

The circular scalpel forms a longitudinal cut through the gums to ensure a clear break or tissue cut for placing dental implants into the bone through the gums.

Description

Sterilizable circular scalpel for cutting the gum in the dental implantation process.

Technical sector

The invention falls within the technical sector of the process of placing a dental implant through the application of an instrument.

State of the art

So far, implant placement involves making a longitudinal incision with a straight-cut scalpel over the toothless alveolar rim in order to discover the underlying bone by separating the gingival tissue and the periosteum from the bone. Once the bone is discovered, with drill bits of different diameters it is drilled to form the implant bed where the implant is placed. Subsequently, the previously detached gum is closed with a suture to cover the bone again with the implant already in place. Then approximately two to three months are expected for osseointregration (implant-bone junction) to occur, after this time and the wound healed it is necessary to perform a second surgery to discover the implant and be able to connect it with the stump that will support the definite crown
tiva.

Currently the general culture of the patient in health has raised the demands of treatment towards speed, post-operative and aesthetic comfort durable, which leads to the development of less invasive techniques possible that respect the integrity of the tissues peri-implants, with the criterion that the more it is removed the more Unpredictable is the result.

Hard and soft tissue maintenance it will depend on the surgical technique that is used, in this it is important experience and skill of the professional who performs the technique.

It would therefore be desirable to obtain a simpler technique and a better post-operative procedure for the patient, that is, avoid detaching the gum attached to the bone and not placing sutures in order to reduce the inflammatory effects of all surgery, the accumulation of food. in the suture threads that make healing and tensions on the wound difficult, as well as reducing the total time of the wound
process.

To this end, the present invention focuses on selectively and precisely detaching the bed that the implant will receive, respecting the integrity of the surrounding tissues as they are not separated from the bone and also avoiding suture placement which significantly reduces the time of the intervention
tion.

Detailed description of the invention

The present invention consists of a single piece With an axis of revolution. Two clear areas are identified as soon as to form and function, one called drive and another called active or cutting. It can be used in two different ways in as far as the drive zone is concerned:

to)

Manual override

For this case The scalpel has a cylindrical volume with a superficial finish effective so that it does not slip between the fingertips of the professional and thus produce the rotation and axial force necessary to make the cut.

b)

Motorized drive

The end of drive has a machining identical to that used by the dental strawberries, so that the scalpel fits conveniently to the contra-angle (lathe) existing in all dental clinics. When the contra-angle is activated, it transmits to the scalpel the rotation that added to the axial force made by the professional produce the cut.

On the other end of the drive and on the same axis of revolution, the active zone or proper court. This consists of a sharp cup shape in its end Its external surface presents a divergence from the edge or active part, towards distal of the same. It also presents a surface milimetrada in its exterior with a series of circumferences carved in low relief and separated by a millimeter the from each other to measure the depth of the incision.

It is presented as a set of scalpels of different diameters to be used according to the diameter of the incision that you want to make and each of the different diameters of the active zone, both for the drive case manual as motorized drive, will be the following: 4.0 mm; 4.5 mm; 5.0 mm; 5.5 mm; 6.0 mm; 6.5 mm; 7.0 mm

The material of which it is composed allows the complete and safe sterilization of the instrument in autoclave

Biomechanics

The specific action of the invention is the cutting gum circular with a margin of 0.5 mm greater than the diameter of the implant Its objective is the removal of the mucoperiosteal layer of the alveolar flange in order to discover the underlying bone for subsequent milling and implant placement, when used in the first surgery, or the discovery thereof when surgery is performed in two phases.

This is achieved by turning on its own axis and deepening in the gum until it reaches the bone cortex, with a Sharp cut and no tear.

Its action is accompanied by an ischemia around the cut, exerted by the pressure made by the scalpel to deepen. This is achieved thanks to the increase in diameter that It has from the edge, which translates into a clean surgical field during the cut with hardly any bleeding, and keeping at all times the correct visualization of the scalpel path during the incision.
