Final year project

Title: design and optimization of dental luxating tools Software used: CREO PARAMETRIC V6 and SOLIDWORKS 2016 Description:

Dental luxating tools are used for removing tooth from the predental tissues surgical equipment which is the tools used in dental tooth exodontia is specific tool will only be used for one specific operation which in turn needs more tools for operation of one single patient which is ok for dental clinics and hospitals but in rural areas and village camps this cause multiple problems In this project I have combined it to one single tool which can perform all the function performed by the dental elevating and luxating tools and Reduce the number of tools carried, made it easy to clean and sterilize the tools fast, our design uses less material, and are handy to use and carry. These elevators approach the ideal for safe effective exodontia Objective

The goal of project is to combine all the different types of elevator into one which can perform all the actions necessary in dentoalveolar surgery and also to provide sleek, handy easy to sterilize elevator

• Include all the straight, left and right elevators

• Any required angle for quick and convenient exposure to all of the teeth

• Make elevator tool handy and convenient for the dentist

• Make it simple to sterilize instrument

• Reduce material used as compared to three tools

• Easy to manufacture and ability for mass production R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com

*These above photographs of the dental elevators are not modelled BEVEL GEAR model (Creo)

This design changes the position of the tip by using a bevel gear mechanism which one of the bevel gear is attached to the shaft which extend to the end which has a screw when the screw is twisted the position of the head changes with it.

R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Advantages of the design

• Small and easy to handle

• Can be made in injection molding

• Double purpose tip both left and right head

Flaws of this design

• The head of the elevator is broad and some part of the mouth are in accessable

• Handle is round and slippery to use

• Only one type of tip can be build only the left and right and not the straight one

• Availability of bevel gear that small is very rare and expensive

• Manufacturing of bevel gear is hard and inexpensive proccessthat consumes lot of time making mass production hard

• Changing of the tips is very hard and requires skill

• Absence of grip in handle make it slip

SWISS knife design (Creo)

With an influvence with swiss army kinfe this deign consist all the three tips the right,left,and straight.this design has very simple geometry and easy to manufacture and very handy R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Advantage of the design

• Consist of all the required tips

• Handy and easy to manufacture

Flaws of this design

• Locking mechanism for the shafts in one fixed direction is not available and unable to design

• The tool has big width which make it hard to gip and hold

• Absence of grip make it slipy

• Tool is bulky

R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com First ball and socket design (Creo)

In this design I came up with new way of locking the tip in one fixed direction with a ball and socket mechanism in which there is a hollow sphere where there is a cut in its bottom which makes a way for a shaft to enter the end of the opening of the sphere has a cone which is larger than the hole cut out so when the shaft is pulled down the cone holds the rotation of the sphere securering it in place when its losen the direction cam be changed and tighted back so that it will not move or slip move.

Advantages of the design

• Able to lock the tip in one fixed direction

• One tip can be used for three purposes left,right,straight sharp

• Even when the screw is not tightened the the ball wont slip out Flaws of this design

• Unable to add straight two point force application tip

• Sterilization will be hard blood accumulating inside the shpere is hard to clean and cause infection to patients

• Due to sphere holder the directional freedom is little compromized

• The handle is small and can cause slipage

• Exposed screw in the rear may cause unintential accidental loosening of the screw disrupting the surgery

• Not Ire sleek design its bulky

R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Second ball and socket design (solid works)

This design is the advancement from the first ball and socket design were we countered some of the problems arised in the third like limited number of tip sleek and deep mouth accessability tips can be changed

R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Advantages of the design

• Sleek and slender design which gives deep mouth accessebility

• Multiple tip can be changed

• Easy to manufacture

Flaws of this design

• Tip locking is just twist lock mechanism which can result in tip unlocking during the surgery and cause sever damage to the throat and esophagues

• Having different tip may result loosing it and defets the actual purpose of new design

• Losening of screw during surgery can occur

• Absence of grips can cause slippage

• Tips gets lost

• Multiple tips are required

R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com

• Sterilization will be hard blood accumulating inside the shpere is hard to clean and cause infection to patients

Neck Ball and socket design (Creo)

In this the ball and socket mechanism is moved to the neck of the elevator its similar to the previous and suffers the same problems but this can also be used as a cross bar elevator. R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Advantages of this design

• Broad handle easy to hold

• The shaft can be moved till 180

o

Flaws of this design

• Tip locking is just twist lock mechanism which can result in tip unlocking during the surgery and cause sever damage to the throat and esophagues

• Multiple tips are required

• Losening of screw during surgery can occur

• Having different tip may result loosing it and defets the actual purpose of new design. Multipurpose swiss design (solid works)

The problems faced in the former designs are eliminated,this equipment supports left sharp,right sharp, straight sharp which can be made by the ball and socket mechanism the straight bent two point force applicator which can be folded back into the handle the screw is moved to the top so it won’t loosen up during surgery by accidental brushing against it.The surface area of the central shaft ball is increased so that the adrasiveness is maximum and prevents slippage,tightening and securing the sharp head is done by screw and thread mechanism, the grip provided makes it easy to grip and provides accurate surgery .the length of the shaft is 90cm which can reach upto the molar teeth and also easy to extract the incessors. R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com The handle is the major part of the elevator it holds all the other components together the head of the handle has a partial shpere where it holds the ball tip ant the rear end there is the Important aspects of this design

• Consists of socket where the tip rest this enables the tip to acts as cyrer’s,straight left,and straight right tips.

• It consists of grip which prevents slipping it can house also the winter’s elevatorin the rear part

• The design is simple and can be produced in injection moulding and casting methods

• Since the screw is in the top accidental loosining of the screw can occur less often in very less often

R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Multi bit screw driver design (solid works)

This idea came up when using a screw driver which there is a slot through the handle and a cap where the tips of dental elevator rather than a screw driver can be slotted into it and then the cap is screwed in now the slots are miss aligned so the tip can come out and it take only two revolution to tighten or loosen a thread completely and it doesn't need complete loosening to remove the tip and different tips can be inserted

R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Advantages of this design

• Multiple tips can be inserted into the slot

• Material consumed is reduced

• Easy to manufacture the tool since it's widely used in market Flaws of this design

• The handle is good for revolution but not for yawing and pitching

• Handle is too bulky making precise operation will be hard

• Accidentally touching of the cap can slip the tip outside R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Cylinder spring locking design (solid works)

This design uses a modified cylinder locking mechanism which is been on market for long period there is a central shaft which keeps the cylinder in the position which locked the tip from rotation and translative motions but when the central shaft is pushed in for rear it gives a space for the cylinders to retract into the hole so that the tips are no longer locked but can be removed and switched for another tip spring is used to retract back the central shaft to its initial position. Advantages of this design

• Multiple tips can be used and can be changed

• Accidentally pressing of button won't relive the cylinders

• Already available in market so easy manufacture which involves very slight modification only

• Handle is flat which is ergonomic and convenient Flaws of the design

Except for multiple tips which can be lost due to human errors there is no mentionable flaws R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Conclusion

Surgical equipment is vital in field of medicine .In this project we have identified a problem a shortage in field of dental surgical equipment which is the tools used in dental tooth exodontia is specific tool will only be used for one specific operation which in turn needs more tools for operation of one single patient which is ok for dental clinics and hospitals but in rural areas and village camps this cause multiple problems and issued like time consuming sterilization, failure to carry all necessary tool due to human error, loosing of equipment,material is consumed more and cost also is very high. Advantages of the design

• All in one equipment

• Easy handling and sterilization process

• Easy prototyping and ability for scaled up production

• Inter changeability of straight elevator is possible

• The tool tip can act as a multiple elevator tool

• Can be manufactured in conventional manufacturing process

• Cost of production will be as same a production on one single tool

• Material consumed for this tool compared to multiple elevator tool is reduced R JOEL JACKSON Phone: 917******* email: adffs2@r.postjobfree.com Other miscellaneous projects
