Biomechanical strategies for optimal finishing
Prepared by:
Dr Mohammed Alruby
الوقاحه هي ان تنسي فعلك وتحاسبني علي ردة فعلي
Finishing: is the last stage of active treatment and depend on the previous stage of treatment
Finishing stage of treatment should be evaluated according to four major categories:
1- Intra-oral:
- Inter arch: midline, and Bolton discrepancy
- Intra arch:
1st order
2nd order
3rd order
Curve of spee
Curve of monson
2- Extra-oral:
Smile arc
Incisors display
Gingival display
Buccal corridor
Incisal plane
Midline
Upper incisor third order angulation
Tooth morphology
3- Radiographic
4- Functional: canine guidance, lateral excursion, anterior guidance
1- Intra-oral objectives:
Intra-arch analysis:
Each tooth must be evaluated with references to its 1st, 2nd ,3rd, order position:
1st order:
- Tooth should have no rotation
- Light inter-proximal contact
- Cusp tip and fossa should follow the perfect arch form
- Buccal surface of upper 1st molar should be parallel to the palatal suture
- An occlusal mirror can be very useful to identify the minor rotation and bucco-lingual displacement of teeth outside the arch form
2nd order:
- The marginal ridges should be at the same level particularly at the buccal segment
- Root parallism should be well
- In extraction cases, small degree of crown tipping will occur and root parallism will required, ----- also accentuating the distal tip in anterior region can help to decrease any excess space in anterior region
3rd order:
- Is most relevant to inter-arch objectives (occlusal relationship)
- A small curve of Monson between the buccal segment allow for proper occlusal function (adequate inter-cuspation without balancing interferences)
- An accentuating curve of Monson results in balancing interferences
- Achieve a gentle curve of spee from the anterior teeth to the posterior buccal segments
N: B:
Curve of spee:
= Anterior posterior curve, produced by F Grave Von Spee in 1890
= It is a line drown beginning at lower cusp teeth following the cusp tip of bicuspid and molars continuing as an arc through the condyle on either side
= There is a reverse curve of spee in maxillary arch
Curve of Wilson:
= Side to side curve
= When looking at a coronal section of mandibular dentition from the front ------ line tangent to the buccal and lingual cusps of mandibular posterior teeth bilaterally
= concave in mandibular teeth and convex in maxillary arch
= this curve helps on:
- Make the teeth alignment parallel to the pull of direction of medial pterygoid which provides optimum resistance to masticatory force
- The elevated buccal cusps prevent the slippage of food from the occlusal table during mastication
Curve of Monson:
= produced by Gs Monson 1920: three dimensional combinations of spee and Wilson
= all cusps and incisal edges in a natural dentition are tangent to a surface of sphere approximately 4 inches (10.2m) in radius with its c

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

23. Carving and polishing.1. Adapt the softened roll of baseplate wax on
the facial surface and extend.
2. Seal the baseplate wax around the neck of
each tooth with a wax spatula.
3. Carve the gingival margins of anterior teeth
with a carver held approximately at 60◦
4. Carve the gingival margins of posterior teeth
by a carver held approximately at 45◦.
5. Use a gas touch to flame the wax surface
taking care not to over heat the gingival
contours. The maxirally waxed denture
shows the gingival contour and the root
forms.
