A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

force
It depends on stress factors
Parafunction
Crown height
Impact width
Implant Number
63. Arch form
English 1993 – AP Spread
Cantilever length = AP spread x 2.5
Tapering - canine and posterior implants with
anterior cantilever
Square - Anterior implant with posterior
cantilever
64. Tapering Ovoid Square
Less dense bone Anterior cantilever with prosthesis Distal
implants, placed to increase AP-spread.
Maxilla - more implants required than mandible
65. Sufficient bone height exist to place long implant,
Avoid contact on central incisors during protrusion, labial
excursion and maximum intercuspation
CANTILEVER FIXED PARTIAL DENTURE
66. Group function - lateral movement
Avoid loading on canine
Lateral guidance provided by central and lateral incisor
67. Two implant supporting a first molar and 2nd premolar with
1st premolar cantilever Active cusp eliminated canine palatal
structures.
68. Three implants placed with Two implants risky
2nd premolar as cantilever and /or contraindicated
69. MANDIBULAR FLEXURE
Picton 1962
Stated that mandibular move towards midline on opening
Because of external pterygoid muscle on ramus of mandible
Medial movement occur distal to mental foramen and
increases as it approaches ramus.
James 1980 & Burch 1982
Movement - 0.8mm - 1st molar
1.5mm - Ramus area
70. FLEXION
Implant - Natural teeth - mandible
0.1mm 0.5mm 10 to 20 times

number of cycles
73. Biomaterial
Stress level below which an implant biomaterial can be
loaded indefinitely is referred as endurance limit.
Ti alloy exhibits high endurance limit
Number of cycles
Loading cycles should be reduced
To eliminate parafunctional habit
To reduce occlusal contacts
74. Implant geometry
Resist bending & torsional load
Related to metal thickness
2 times thicker – 16 times stronger
Force magnitude

Eliminate torque
Increase in surface area
75. IMPLANT DESIGN & BIOMECHANICS

Wall thickness = (outer radius)4_ (inner radius)4
If outer diameter increases by 1mm & inner diameter unchanged
33% increase in bending fracture resistance
If inner diameter decreases by 1mm & outer diameter unchanged
20% increase in bending fracture resistance
79. Implant macrogeometry
Smooth sided cylindrical implants – subjected to shear
forces
Smooth sided tapered implants – places compressive
load at interface
Greater the taper – greater the compressive load delivery
Taper cannot be greater than 30 degree
Implant width
Increase in implant width – increases functional surface
area of implant
Increase in 1mm width – increase in 33% of functional
surface area
80. Implant length
Increase in length –Bicortical stabilisation
Maximum stress generated by lateral load can be dissipated by
Implants in the range of 10-15mm
Softer the bone –greater length or width
Sinus grafting & nerve re-posititioning to place greater implant length
Resistance to lateral loading
81. Crestal module design
Smooth parallel sided crest –shear stess
Angled crest module less than 20 degree-
-Increase in bone contact area
-Beneficial compressive load
Larger diameter than outer thread diameter
-Prevents bacterial ingress
-Initial stability
-Increase in surface area
83. Surface Coating
-Titanium plasma spray
-Hydoxyapatite coating

-Plaque retention
-Nidus for infection
-Increased cost
84. IMPLANT PROTECTED OCCLUSION
Occlusal load transferred within physiologic limit
Misch,1993
width of occlusal table directly related to implant width
Narrow occlusal table with reduced buccal contour permits
sulcular oral hygiene
Restoring occlusal anatomy of natural tooth
-offset load
-complicated home care
86. Apical Design
Round cross-section do not resist torsional load
Incorporation of anti –rotational feature
-Vent hole- bone grow the hole
-resist torsion
-Flat sidegroove - bone grow against
-places bone in compression
90. IMPLANT ORAL REHABILITATION
Constitutes
Muscle relaxation
Absence of articular inflammation
Stable condylar position
Creating organic occlusion
Absence of pain in stomatognathic system
91. Organic occlusion components
Correct vertical dimension
Maximum intercuspation in centric relation
Adequate incisal & condylar guidance
Stable bilateral posterior occlusal relation in equilibrium with
long axis of implant
Absence of prematurities
Absence of interferences in eccentric movements
92. Bruxism patients
Education & informed consent to gain co-operation in
eliminating parafunction
Use of night guard
- anterior guided disooclusion
- posterior cantilever out of occlusion
- soft night guard releived over
implant
Soft tissue supported prosthesis
- soft tissue tend to early load the
implant & hence relieved over it
Removable partial denture over healing abutment
- 6mm hole diameter through metal is
prepared
94. CONCLUSION
Biomechanics is one of the most important consideration
affecting design of the framework for an implant bone
prosthesis.It must be analysised during diagnosis &
treatment planning as it may influence the decision
making process which ultimately reflect on the longevity of
implant supported prosthesis
