9. Maxillary Immediate Partial Denture

10. Restoration of Mandibular Occlusal Plane

11. “A removable partial denture or complete denture that covers and rests on one or more remaining natural teeth,the roots of natural teeth,and or dental implants;a prosthesis that covers and is partially supported by natural teeth,natural tooth roots,and or dental implants.”
It is also called :
Overlay denture,
Overlay prosthesis,
Superimposed prosthesis

12. Three different abutment categories:
Non coping,
Coping and
Attachments

13. Advantages of an Overdenture
Preservation of alveolar bone
Proprioceptive feedback
Support
Retention
Psychological aspect
Convertibility

14. Disadvantages of an Overdenture
Plaque retention
Secondary caries
Encroachment of the interocclusal distance
Need for endodontics
• Bulk of attachments & tissue undercuts
Difficulty in achieving shade
Cost

28. The long-term success of using teeth as overdenture abutments has been well documented.
A study by Crum and Rooney compares bone loss between patients with conventional dentures and patients with overlay dentures.By retaining the mandibular cuspids in the use of an overdenture,the resorption of the alveolar bone surrounding these teeth was reduced by eight times.
Toolson and Taylor showed that,over 10years, 66 out of 77 abutments survived and,of the 11 that failed,6 were due to secondary caries.

29. SUMMARY
A changing paradigm in the treatment planning of patients with a compromised dentition includes an understanding that sometimes it is better to extract non-strategic or severely compromised teeth and to use the natural teeth in a key position for an overdenture.
