• Length of edentulous span
• No abutment tooth posterior to the
edentulous area

28. Evaluation of occlusion
• Collapsed occlusion
• Traumatic occlusion
• Deranged occlusal plane
Herbert T. Shillingburgwww.indiandentalacademy.com
29. • Signs of traumatic occlusion
– Excessive wear of teeth
– Chipping or fracture
– Tooth mobility, migration or discomfort during
occlusal contact
– Pain in the T.M.J , muscle spasm or joint
dysfunction
• Radiographic
– Widening of periodontal ligament space
– Thickening of lamina dura
– Root resorption or alveolar resorption

30. Signs of collapse of occlusion
• Collapse of vertical dimension of
occlusion
– Requires extensive treatment
www.indiandentalacademy.com
32. Treatment Objectives
• Restore lost tooth structure
• Restore lost VD
• Establish new horizontal relation
• Develop new engram
• Transfer data to articulator
• Develop new occlusal relationship for
the established VD&HR

43. Management of less
Interarch space.
1. Surgical reduction of
tuberosities.
2. Osteoplasty and /or soft tissue
reduction of implant region
3. Selective grinding
4. Prosthodontic restorations
5. Endodontic therapy.

44. Management of increased
Interarch space.
•MMay be decreased by addition
of onlay grafts .
•AAutogenous and /or membrane
grafts.
–AAlloplastic grafts

64. Fixed Splinting
• Incase of compromised periodontal support
of remaining teeth
• Short tapered roots
• To improve support for the partial denture
www.indiandentalacademy.com
71. Removable splinting
• When abutment teeth exhibit a alveolar bone
loss of greater than 50% splinting them by
means of fixed splints to adjacent healthy
teeth, the adjacent teeth is also subsequently
weakened
• Splinting may also be accomplished using
properly designed removable partial dentures
www.indiandentalacademy.com
72. • This is done by means of lingual plating in
conjunction with multiple facially positioned
clasp arms
• Thus remaining teeth and removable
prosthesis functions as a single functional unit
• Forces are distributed over increased number
of teeth, increasing the longevity of the
remaining teeth
